What is APM?


APM ( Advanced Power Management ) is a power management BIOS specification for reducing the consumption of power in battery-powered notebooks.

 

Retour à la table des matières

 

What does APM do?


APM ensures that the components in the Notebook (UART, DMA, CPU, etc.) that are not being used are put in a lower power mode.

The APM software interface specification defines an environment which allows the application software, operating system, device drivers and the APM BIOS to work together.

 

Retour à la table des matières

 

What is the APM BIOS?


The APM BIOS is the software interface to the Notebook’s motherboard which holds the components whose power consumption can be managed.

 

Retour à la table des matières

 

What is the APM driver?


The APM driver is a component of the operating system which interfaces with the APM BIOS and controls the power management. The APM driver communicates with APM-aware applications.

The definition of APM consists of various states which an APM controlled Notebook can assume, e.g. APM enable, APM suspend.

Windows 95's advanced mobile functions include the APM driver and utilities, as standard.

 

Retour à la table des matières

 

What is the enable state?


The enable state is, for example:
Notebook is in use.
The Notebook is under APM control.
The CPU clock switches to a lower speed or stops.

 

Retour à la table des matières

 

How does the Notebook enter the enable state?


The APM enable state can be turned on and off by users themselves. This can be done in both Windows 95 and DOS/Windows 3.11. The advanced option can be selected in the Power program located in the Windows 95 control panel. The Notebook will now be in the enable state. In DOS/Windows 3.11, it is turned on and off as follows using the 'POWER.EXE' utility program:

POWER.EXE ADV:REG (APM controls power consumption)
POWER.EXE OFF (APM is off )

When the Notebook is being controlled it can be placed in the suspend state.

 

Retour à la table des matières

 

What is the suspend state?


The suspend state is, for example:
Notebook is not in use.
Most devices have been disabled.
The CPU clock is off.

Operational parameters are saved so they can be restored when the Notebook comes on again.

 

Retour à la table des matières

 

How does the Notebook enter the suspend state?


The Notebook can enter the suspend state in various ways.

1. System suspend request

The system suspend request is, in other words, the means by which the on/off switch or the cover switch places the Notebook in the suspend state. The APM BIOS requests the APM driver to place the Notebook in the suspend state. It is then the responsibility of the APM driver to determine whether the system can be put in the suspend state.

The APM driver sends a signal to APM-aware applications concerning the system suspend request. This signal allows APM-aware applications to prepare for the suspend state. The APM BIOS is not allowed to simply to put the Notebook in the suspend state without performing these checks.

The operating system can delay entry into the suspend state if files are still open or the Notebook is connected to a network, etc. The APM driver then looks every five seconds to see if it is possible to put the Notebook in the suspend state. While the system is in trying to enter the suspend mode it beeps to inform the user that it is waiting to enter the suspend mode.

2. User system suspend request

The user system suspend request is, in other words, the means by which clicking on an icon, selecting a menu option or entering a command places the Notebook in the suspend state. The user thus makes a request to the APM driver to place the Notebook in the suspend state. It is then the responsibility of the APM driver to determine whether the system can be put in the suspend state.

The APM driver provides a signal to APM-aware applications concerning the system suspend request. This signal allows APM-aware applications to prepare for the suspend state. The APM BIOS is not allowed to simply put the Notebook in the suspend state.

The operating system can delay entry into the suspend state if files are still open or the Notebook is connected to a network, etc. The APM driver then looks every five seconds to see if it is possible to place the Notebook in the suspend state. Depending on the operating system, the user may be informed by a series of beeps if the system needs to wait for suspend mode. Windows 95 does not make any noises while waiting.

Modem.

 

These days, when using a modem can be more or less regarded as "widely understood", there still appear, however, to be some uncertainties concerning the modem and configuring it. It would not be appropriate to discuss these issues in detail here, so we restrict ourselves to giving a few useful AT commands with a description of their applicability. We assume that you are familiar with the use of the Hayes Command Set and the Terminal Mode of a communications program such as Terminal in Windows 3.xx and Hyperterminal in Windows 95. This covers the following Toshiba modems:

I1I2I3I4I5I6: Information on the modem can be obtained by using this line. The response of the modem gives indications concerning, for example, Product Code, Release Code of the firmware and in some cases concerning the Manufacturer and/or country setting. For example, the OPTEGRA Gold Card V34 PCMCIA modem is FLASH-upgradable: By entering ATI3, the release code of the firmware appears which makes it possible in certain cases to determine whether a FLASH Upgrade is required or not. So, with this command, you can see without removing the modem which make and type it is.

X0: This command selects the Standard result code and turns off Dial Tone recognition. The latter can be useful when you want to initiate a call abroad: The modem will immediately dial the number without first checking whether the dial tone is present. This thus allows the modem also to be used abroad. This only works for outgoing calls, however. Incoming calls will probably not be possible due to differences in the "Ring" signal.

Z(n): The modem is reset and configured with the settings from profile (n). n can be 0 or 1 (see &W). During this reset, modems with automatic (line) interface recognition check to see what (line) interface is actually connected to the modem and configuration takes place accordingly.

&C1&D2: These two commands usually go together: They ensure that the modem follows the status of the Carrier. When the carrier goes low, the modem will "disconnect".

&W(n): This command gives you the possibility of writing an active configuration to either profile 0 or profile 1. These profiles are generally resident, so highly suitable for permanently setting two different profiles. HINT: When software is used which does not offer the option of entering an initialisation string, the "hard-coded initialisation string" usually consists of ATZ. The modem will be reset and configured with profile (0) settings. So, before the above-mentioned program is started, you can assign the right configuration/parameters to profile 0. (E.g. via echo at……… > com(n) under DOS.) You then start the communication program and it should be configured with the settings from profile 0. You will have thus "sneakily" created an initialisation string.

&F: Restore Factory Settings. The modem is restored to the factory settings without erasing the contents of profiles 0 and 1. This is a fixed reference or starting point when configuring a modem. When this command is included in the modem initialisation string, it can sometimes cause problems. Restoring the factory settings can take the modem too long. In such cases the ATZ command can provide a solution.

&V: This retrieves the active configuration plus the contents of profiles 0 and 1. Unfortunately not all settings may be shown. \N3, for example, is usually not to be found but \S, on the other hand, may well apply.

%C0: MNP5 and V42bis data compression are disabled with this command, which can be a help when there is both hardware and software data compression (e.g. when downloading using the z-modem protocol). When an error arises due to a fault on the line, the error correction will have to ‘battle its way’ through both data compressions which will mean that the download speed will fall off dramatically. By adding %C0 to the initialisation string, hardware compression is disabled so that only the software data compression is active and any errors on the line can be much more quickly fixed. The (download) speed will then remain higher and more constant.

\J1 (not supported by all modems): Adding \J1 can in some cases add to the stability of the connection. The speed of the com port is adjusted to the line speed.

\N3 Auto-Retrain: The modem starts by attempting to connect at the highest possible baud rate and may switch back to a lower speed when the modem it is calling does not respond to the higher communication speed.

S Registers
The Hayes command set includes the ability to set certain registers within the modem, enabling or disabling certain features. These normally take the form of ATSn=xyz, where n is the register and xyz the value to be set. See your modem's manual for more details, since these are often different on different makes of modem. However, one theat is very useful for users of Toshiba's integrated world-wide modem is register S133, which allows you to set the country settings, using the following table of values:

Country Register value (Hex)
USA/Canada 19
Australia 1
Belgium 2
Denmark 3
Finland 4
France 5
Germany 6
The Netherlands 7
Italy 8

Introduction for all battery-powered Toshiba computers.

 

All modern notebooks use rechargeable batteries.These batteries can be of the NiCd (Nickel Cadmium), NiMh (Nickel Metal Hydride) or Lithium Ion type.

The NiCd and NiMh batteries have virtually the same properties, except that NiMh does not contain the heavy metal Cadmium and so is less harmful to the environment and has a slightly longer lifetime.

The Lithium Ion battery offers the most advantages for the user.

To get the most from the battery, it is advisable that you train it. You do this by working under battery power as much as possible. It is therefore also advisable that you observe a set working method.

To make this completely clear, we will explain a number of issues in more detail below.

Recommanded working method with NiCd and NiMh batteries.


To get the most out of your battery, it is advisable to consider a set working method. An example is described briefly below.

You charge the battery just until the battery LED lights up green. You then remove the AC adapter or power cable and so work using the battery.

As soon as the battery is almost empty, the computer gives a signal in the form of a red blinking battery LED. This means that you still have a limited amount of working time left. If you have more than one battery, put the computer in RESUME mode (this can be done using the Fn+F3 key combination, MaxTime or in the Setup of the machine) and turn the computer off by pressing the on/off button. Swap the empty battery for a full one and start the machine up again.

If you do not have a spare battery, proceed as follows:

When the computer tells you that the battery is empty, connect the AC Adapter or power cable. You will now work using the adapter.

Depending on the type of machine, the battery is or is not then being charged (see table).

When the battery LED goes green again, remove the AC adapter or power cable and you will again be working using the battery.

Repeat this process each time and you will know that when you need the battery you can rely on it. You will also instinctively know how long you can work between battery recharges.

When you are certain that you will be at the office all day (and so working with an AC adapter or power cable), charge the battery until the battery LED is green and then remove it from the machine.

Recommanded working method with Lithium Ion batteries.


The recommended working method in 4 is aimed at reducing the notorious "memory effect". Since Lithium Ion batteries do not suffer from the memory effect you not need strictly follow the working method in 4.

It might, however, still be a good idea to observe a set working method. After all, mobility and flexibility stop when your battery is empty.

Lengthening the working time between battery recharges.


You might already be aware that power consumption is directly proportional to the performance of the system.

This means that when you want to achieve a longer working time before recharging the battery, this will be at the cost of performance.

You can work longer between battery recharges by cutting down in a selective way on the major consumers of power.

What are these consumers of power?

- processor
- LCD panel illumination
- Hard disk / CD-ROM

With the aid of various MaxTime Power Management options such as: Lower Processor Speed, Sleep mode, HDD Auto off, Display Auto off and LCD brightness and by turning on the Advanced Power Management, it is possible to achieve a longer working time.

Charging and battery usage tips for all battery-powerde TOSHIBA computers.


Discharge the battery until the computer gives a signal in the form of a red blinking battery LED.
Recharge the battery at room temperature. This is the temperature at which the battery will give the longest working time.
If the computer is not being used for longer than a week, charge the battery and remove it from the computer.
If you have more than one battery, use them in rotation.
Work as much as possible using the battery and as little as possible with the adapter/power cable.
We would also like point out that the battery is a consumable item and has a limited life.
With proper use, proper charging and discharging, you will increase its life.

Battery Pack.

Battery packs are completely discharged at the time of purchase. Therefore, you must charge fully before using your computer. Totally discharging the battery pack before charging, will allow the battery pack to be charged to its highest capacity. When the battery pack runs out, the LED will blink in red. Connect the AC adaptor to recharge the battery. When not in use, the battery slowly discharges. When not in use for a long period, the battery may be completely discharged.

Checking the remaining battery capacity
When the LED turns red, the battery will run out in 3 minutes. Connect the AC adaptor immediately. The remaining battery capacity can be read from the icon bar. If your PC does not have an icon bar, use the Pop-Up Window. The Remaining Battery Capacity Gauge shows E for empty, F for full. Always turn your computer off and remove the AC adaptor when switching battery packs.

Cleaning the battery terminals
Keeping the battery terminals clean will help maximise the operating time. Wipe the positive and negative terminals with a dry cloth. Removing and replacing the battery pack will ensure electrical contact. This should be done when using a battery that has not been used for a long time.

Maximising the operating time of the battery pack
Enable Resume, and turn your computer off when not in use. Close the display, if you are not using the keyboard. Set the Display Auto Off option to the minimum value. Set the HDD Auto Off option to the minimum value.

How to maximise the life span of your battery pack
Remove the AC adaptor when the battery is fully charged. Use the battery pack until it is completely discharged. A green battery LED indicates that the battery pack is fully recharged. Note that the operating time decreases at low temperatures.

Advanced Power Management (APM)
The latest Toshiba battery operated machines support the industry standard Advanced Power Management. As more applications become APM aware, standard battery life will be increased.

Where to store battery packs
Battery packs should be stored in a cool, dry place, out of direct sunlight. The battery pack slowly dissipates its charge over time. At 20 degrees C, or 68 degrees F, this will occur in about three months.

When a battery pack needs to be replaced
A battery pack can be recharged about 500 times when used as directed. If the battery light blinks red shortly after fully recharging the battery, the battery needs to be replaced. Please purchase a new battry pack.

Recommended operating conditions when charging
A battery pack is charged to its full capacity if charged under room temperature. The recommended charging temperature is 10 to 30 degrees C (50 to 86 degrees F).

The battery charger where applicable
The Battery Charger can charge up to three battery packs. It is ideal for use with spare battery packs.

Spare battery packs
You can increase portability with additional battery packs.

Increasing the number of interrupts.

As the number of standard equipment and devices increase on notebooks, the number of free interrupts decrease.

Taking the Toshiba 510CDT as an example, there are 2 free interrupts available when the machine comes out of the box. If Cardbus mode is used for PCMCIA, only one interrupt is left. If the machine is docked to the Enhanced Port Replicator II or a Desk Station V+, no free interrupts are left. This makes adding other devices like PCMCIA cards difficult.

Configuration A = 510CDT Default Settings, Preinstall Software.

Configuration B = 510CDT Default Settings except PCMCIA = Cardbus Mode, Preinstall Software.

Configuration C = 510CDT Default Settings except PCMCIA = Cardbus Mode, Preinstall Software, DSV+.

  1. Unless the end user is running a PC card (PCMCIA) that needs Cardbus, switch to PCIC mode. This will save one interrupt. If no PCMCIA cards are going to be used, either disable the PCMCIA slots or put them in PCIC mode. Do not leave the slots in Cardbus mode if they are not to be used.
  2. Disable any unused ports or devices. These ports could include Infrared, MPU-401 (MIDI), COM1, COM2 (Modem) and LPT1. For example, if a Tecra 740CDT machine is docked to a Desk Station V+, the Infrared port cannot be used and should be disabled. The MPU-401 is one of the least used ports so it can be disabled by most users.

Toshiba DAA modem support.

Fax modem to 33K6
Upgrading the Toshiba Advanced PCMCIA V34 modem from 28.8Kbps to 33.6Kbps is possible due to its built-in Flash Memory that allows users to upgrade the modem to the latest specifications. This again shows the benefit of the Flash Memory in the Toshiba V34 modems which offers the user optimum protection of investment. With the new ‘firmware’, it is possible to upgrade the Toshiba V34 modems from 28.8Kbps to 33.6Kbps. In comparison with existing 28K8 modems, the speed with which files can be exchanged increases significantly. With the upgrading of the Toshiba V34 modems, Toshiba Benelux is anticipating the extension in the near future of the current V34 standard for 28.8Kbps of the International Telecommunications Union (ITU) up to a speed of 33.6Kbps.

Firmware upgrade instructions (Ver. 724 - 33.6Kbps)
The upgrade method described below is only possible with an MS-DOS or Windows 95 PC. If the Toshiba V34 modem is used in a Macintosh or OS2 system, the upgrade must be performed on a PC with MS-DOS or Windows 95. The upgrade to 33K6 can only be performed on Toshiba V34 modems which have a serial number higher than 3100449. The Toshiba V32bis PCMCIA modems cannot be upgraded.

  1. Ensure that the Toshiba modem is in the right PC card slot (the slot that you always use for the Toshiba modem.
  2. Ensure that your notebook is being powered from the normal mains power supply; do not use the batteries in your notebook during the upgrade
  3. If you use Windows 3.11 or 95, go to the DOS prompt
  4. Insert the disk with the upgrade files in drive A or B
  5. Type A:\ or B:\ (depending on the drive in which you inserted the disk) and then <ENTER>
  6. Type PDENA APBI724.BIN <ENTER>

The upgrade will now proceed and take just a few seconds. The notebook must be restarted after the upgrade before the Toshiba modem can be used again.

Troubleshooting
Problems concerning the upgrade of your Toshiba modem may arise if the PDENA.EXE program cannot make contact with your Toshiba modem, your Toshiba modem itself is not suitable for an upgrade or when your Toshiba modem already has the latest firmware.

PDENA cannot make contact with your modem
When you attempt to perform the upgrade, a number of different error messages may appear which indicate that the PDENA program cannot communicate with your Toshiba modem. Error messages that often arise in these cases are:

Card is not present Your Toshiba modem is in the wrong PC Card slot and so cannot be found by PDENA. Place the modem in another PC Card slot and try to perform the upgrade again. If you do not have any other slots in your notebook, type PDENA APBI724.BIN /B

Invalid base Memory Address Communication with your Toshiba modem is being hampered since a specific part of the required memory is being used. To solve this problem, you can make a change to your CONFIG.SYS in which you must use the EMM386 option:

When using DOS
DEVICE=C:\DOS\EMM386 …(OTHER OPTIONS)… X=D000-D400

When using QEMM

DEVICE=C:\QEMM\QEMM386 …(OTHER OPTIONS… /X=D000-D400

Your Toshiba V34 modem is not suitable for an upgrade

When your Toshiba modem does not have the right chipset (the serial number is lower than 3100450), it will not be possible to upgrade your Toshiba modem. The following message will appear on your screen; 'Incompatible upgrade file for product'.

Your Toshiba V34 modem already has the latest firmware

If your Toshiba modem already has the latest firmware, you will of course not need to upgrade it. The following message will appear on your screen: 'Upgrade not required because card has same firmware'.

Pre-installed software.

All machines are supplied with both DOS/Windows 3.11 and Windows 95 installed on the hard disk. Users are able to make a choice of the operating system they want to work with. This is a once only choice and the operating system not chosen is then deleted.

The contract that Toshiba has concluded with Microsoft does not provide for DOS and Windows to be supplied on diskettes or CD-ROMs with the machines. For DOS and Windows 3.11, the software is provided as ‘images’ on the machine; the end user can transfer this software to diskette with the Master Disk Creator, thereby obtaining the original Microsoft software and the special Toshiba software. There is a similar procedure for Windows 95, with the difference that the original Microsoft software can only be copied once to diskette.

In addition, every end user with Internet access can download special drivers and utilities from the European Support Centre.

Upgrading Processors.

Many notebook users ask about the possibility of upgrading older notebooks with more recent and powerful processor technology. Unfortunately, it is not possible to upgrade the processors used in Toshiba notebooks. There is a good reason for this. The design of the processor is completely different from those used in desktops. The Intel processors are soldered directly onto the motherboard by means of an advanced production process known as Tape Automated Bonding (TAB). This process, together with the related TCP (Tape Carrier Package), makes it possible to squeeze Pentium technology into the confines of an A4 notebook and still cope with the vast amounts of heat that Pentium produces.

For notebook users who wish to increase the speed of processing, we recommend looking at the option of increasing the working memory (RAM). Graphical operating systems, and especially Windows 95, work much better with increased memory. This is a much more cost effective method of increasing speed. We recommend moving to 16 MB from 8 MB, or to 24 MB or 32 MB if users are not in the market for a new notebook. The more graphics intensive notebook is, the faster the PC will be with more memory.

The Resume mode.

Customers have been reporting varying lengths of time and beeps emitted when shutting down the computer in Autoresume mode and they want to know what is "normal". They have reported anywhere from 2-3 beeps and a couple of seconds to shut off all the way up to 15+ beeps and about 20 seconds until the power has been switched off.

To some customers it's not really clear what the resume mode is really doing, especially with any applications that might be running at the time of shutdown. In order to determine what is to be expected during resume shutdown, our engineering department was asked what type of "housekeeping" procedures the resume mode added to system shutdown and what variables might affect that process.

The length of time/number of beeps to complete shutdown depends on the interaction of APM (under resume) (see note, below) with those application software packages using the power management facility. Since we have designed in support for APM (both APM.SYS supports and the APM in BIOS on the newer machines) the process to shut down under resume has involved a routine status query of APM aware/active applications running on the system.

The bottom line is: the system waits for the response of the application that all APM service interaction has been tidied up and suspended in preparation for shutdown. The query is on a timing cycle of clock ticks and so we are always close to ready for shutdown since we are repeating this query continuously while in resume mode. The software application is then reporting to the system under the program calls to APM.

Software programs aren't always well behaved in their calls to APM. Some apps don't return the expected response to the system under proper APM protocol. Other apps don't return a response at all! This delays the ability of the system to respond quickly to the shutdown process. The system waits for the response from applicable APM affected programs and if it doesn't get an answer within a certain amount of time then shutdown happens regardless via a "timed out" default. The system takes close to 20 seconds to "give up" and time out and almost as many beeps are emitted while the system finishes waiting. If an application is open under Windows and it gets "lost" in its own program code when queried then it may not have done the cleanup needed for it to close out smoothly. This is why proper APM configuration is so important when using the 32 bit file access option under MS Windows for Workgroups. The access needs to be supported by the APM configuration on the laptop to insure that the computer's battery save mode features don't interfere with activities involving file integrity. (In other words - trashed files/directories can result from improper APM configuration.)

Under the MS-DOS operating system, this type of timing out for "no response" from the software may mean a resume failure when powered back up. If an user complains that his autoresume feature is unreliable and hardware testing doesn't reveal anything wrong (good backup battery and mains are charged) then it is possible that APM configuration of the system is having trouble with a particular program or combination of programs supposedly APM aware.

*APM Note: This is assuming that the Toshiba computer is a model that supports APM and that the system is configured correctly for power management. The setup varies within the models by level of APM support (1) APM.SYS installed in config.sys or (2) APM contained within the system BIOS. The MS-DOS device file POWER.EXE must be installed within the config.sys file for APM to be enabled.

In either case, configuring the Windows environment is the same across the Windows 3xx platform (including Windows for Workgroups). APM support is enabled for Windows by specifying the MS DOS with APM as the system type. This selection installs a virtual driver within the [386enh] section of the system.ini file for Windows called: vpowerd.386.

This article lists steps to help you troubleshoot problems using the Shut Down command in Windows 95.

When Windows 95 shuts down it performs many functions, including the transition of all protected-mode drivers back to real mode, the completion of all disk write functions and flushing of the disk cache, and the closing of all currently running programs, which also includes running the running programs' Close Window code. When Windows 95 does not shut down properly, it may appear to stop responding (hang) for several minutes, holding at the "Please wait while your computer shuts down" screen.

Shutdown problems in Windows 95 can be caused by an incompatible, damaged, or conflicting device driver, a damaged exit sound file, or incorrectly configured or damaged, hardware. To troubleshoot this problem, perform the following steps:

d. Restart Windows 95. When Windows 95 restarts, you receive the following error message: Your Display Adapter is disabled. To correct the problem, click OK to open Device Manager. Click Cancel. When the Display Properties dialog box opens, click Cancel. If Windows 95 continues to hang on shutdown after you complete these steps, reinstall Windows 95 to a different folder to rule out the possibility of damaged files. For example, if Windows 95 is currently installed in the Windows folder, install it in the Win95 folder. If your computer has a Plug and Play BIOS, you may want to reinstall Windows 95 using the "setup /P I" command to rule out a bad Plug and Play BIOS. If Windows 95 still hangs during the shutdown process after you reinstall it, your computer may have faulty hardware or faulty system components including RAM, the CPU, or an internal or external cache. Contact your computer's manufacturer for assistance.

 

View the Bootlog.txt file to pinpoint the problem. If Windows 95 still hangs during the shutdown process, examine the Bootlog.txt file for "Terminate=" entries. These entries are located at the end of the file and may provide clues as to the cause of the problem.

 

Each "Terminate=" entry should have a matching "EndTerminate=" entry on a successful shutdown. If the last line in the Bootlog.txt file is "EndTerminate=KERNEL," Windows 95 shut down successfully. If the last line in the Bootlog.txt file is one of the following entries, check the listed possible cause:

Last line Possible cause


Terminate=Query Drivers Possible QEMM or other memory manager issue.

Terminate=Unload Network Possible conflict with real-mode network driver in the Config.sys file.

Terminate=Reset Display Disable video shadowing. You may also need an updated video driver.

Terminate=RIT Possible timer-related problems with the sound card or an old mouse driver.

Terminate=Win32 Problem with a 32-bit program blocking a thread. Possibly Microsoft Visual C for Windows. KBCategory: kbtshoot kbenv KBSubcategory: win95

Does a Toshiba notebook have simultanious video?

Yes, a Toshiba notebook has the capability of displaying the image on its own display as well as on an external monitor. The resolution for simultaneous video depends on the resolution of the notebook’s TFT/STN display. If the notebook’s display is 640 x 480, this will also be the resolution for the external monitor. This also, for example, applies for a notebook resolution of 800 x 600 - the resolution for the external monitor will also be 800 x 600 in simultaneous mode. The resolution for the external monitor may also be set to another value. This depends on the notebook’s capabilities. See the user’s guide for your notebook.

Display problems can arise when an overhead display with a resolution of 640 x 480 pixels is used and the resolution of the notebook display is 800 x 600 pixels or higher. When configuring the display to a resolution of 640 x 480, which is required for the external display, this resolution is emulated on the notebook’s display. This means that there is a black border on the notebook’s display containing a screen with a resolution of 640 x 480 pixels. The TFT is, however, still being driven at 800 x 600 pixels, so if an external display with a resolution of 640 x 480 is then connected, this will not display the image correctly in simultaneous mode.

If you only drive the external display, so are not in simultaneous mode, the notebook’s video controller will switch to a screen resolution of 640 x 480 and the image will be correct on the external display.

The image is properly displayed in simult
