Does my 5400 have Plug and Play BIOS?

The there are two versions of ChemBook™ 5400, the 5400 and the 5400P. The major difference between the two is that 5400 does not support Plug and Play, while the 5400P does support Plug and Play. There are two ways for you to determine which version you currently have.

1. Look at the bottom of the notebook, and look for the label with the model number. If the model number is "5400T" for TFT or "5400D" for Dual Scan, then you have the older version without Plug and Play BIOS. If the model number is "5400PT" for TFT or "5400PD" for Dual Scan, then you have the newer version with Plug and Play.
2. Boot up the computer, and look on the first screen. If you see the line "Plug and Play BIOS Extension v.1.0", then you have the newer version with Plug and Play BIOS. If you don't see the above message, then you have the older version without Plug and Play BIOS.

If you need BIOS update, go here. If you have 5400P, then download the file 54pv24.exe. If you have 5400, then download the file 54v601.exe.

Why doesn't the floppy drive work with 64MB Installed?

If you have 64MB of system memory installed, you must upgrade the BIOS to version 2.3 or above. Otherwise you will not be able to access the floppy drive. To download the BIOS Update file, click here. Since you must boot from a system diskette to upgrade the BIOS, you would need to remove one of the 32MB DIMM modules before you upgrade the BIOS by opening the CPU panel on the bottom side of the notebook. After the BIOS is upgraded, you can re-install the DIMM module.

How do I use the floppy drive and MPEG Module simultaneously?

If you wish to use the floppy drive and the MPEG module simultaneously, you must install the MPEG module in the floppy drive bay in the notebook, and install the floppy drive in the mini docking station. Then, start the computer, press Ctrl-Alt-S to enter the BIOS configuration setup, and disable the option "Internal FDC" in the Disks menu.

Why does the trackpad behave erratically in LCD Expansion Enabled Mode?

If you have a SVGA LCD, and use 640x480 VGA mode expanded to fill the screen, you will notice that the mouse behaves erratically, i.e., it clicks on something it is not pointing on. To resolve this problem, you need to disable the LCD expansion mode and use either 640x480 VGA resolution with a border around the display. In order to display full screen correctly, you have to use SVGA 800x600 resolution.

How do I restoring battery capacity?

Because of the battery's "memory" characteristic, the batteries need to be fully drained and recharged to restore the full power capacity if it is used for the first time or after extended usage. The following shows how the full battery life can be restored.

1. Keep the machine on until the machine shut off automatically due to low battery, even if there are battery low warning beeps.
2. Pull out the battery and let it cool down. To prevent overheating, the machine stop charging the battery if its temperature is over a certain limit.
3. After the battery is cooled down, plug in the battery and AC adapter. The Power-On LED Indicator (the left LED on the right side of the notebook) will show a red color and will turn to orange color after a few seconds, meaning that the battery is being charged.
4. Wait until the Battery-Charge LED Indicator (the right LED on the right side of the notebook) turns to green color, which means battery is full or that AC adapter can not charge the battery any more.
5. Pull out the battery and let it cool down. Repeat steps 3 and 4. After the battery is charged for the second time, the original battery capacity should be restored.
