Questions and Answers

Q: My computer gives me a CMOS error
A: If the CMOS battery is empty, you will be prompted with the following error when you power on the machine.

**** Error in CMOS.  Bad check sum ****
*** Error in CMOS. Bad memory size ***
** Error in CMOS. Bad configuration **
Check system. Then, press [F1] key.....

Please refer to instructions here:
How do I boot my T3100e with an empty CMOS battery

Q: How can I access the built-in BIOS ?
A: Press CTRL + SHIFT + F10 when the computer powers on. If this does not work, you may use the TEST3.EXE utility, a little program by Toshiba which will open up the BIOS settings from a DOS environment. You might want to include this utility in your computer recovery disk. See below for files that apply to this type of machine, or view all files at the files and resources section.

Q: I am still unable to access the BIOS.
A: When the computer BIOS battery runs empty, it will clear all BIOS settings and will prompt you to review the system settings on power-up. This may be used to your advantage to get into BIOS. To force this behavior, disconnect the clock battery entirely. Wait for a few minutes and power up the computer again. The computer will ask the user to review the default settings. Please refer to How do I boot my T3100e with an empty CMOS battery

Q: My computer does not hold settings or time
A: You probably have an empty BIOS battery. The battery holds volatile information in a CMOS chip like information about your BIOS settings and system time. When the battery runs out, the information will be lost. You can still use your computer by going into BIOS settings and accepting the defaults (see above).

Q: How do I replace the computer BIOS battery?
A: The BIOS battery is located on the system board. The correct voltage for the battery is 3.6V. You can replace it with either an original part, or alternatively, you can replace it with a 3.0V CR2032 coin cell battery. In this case you should buy a CR2032 holder, a CR2032 lithium battery and a diode. The diode is required to avoid charging the battery. Take the old battery connector and its wires, solder the coin cell holder to the wires and solder the diode in series as such:
