Toshiba Satellite A200 notebook BIOS UPDATE v.1.50-WIN for Windows Vista
Before updating BIOS
You MUST have the AC Adapter connected to your notebook prior to updating the BIOS. Failure to do so, may cause damage to the notebook if the notebook loses power and fails to complete the update process.
In the event of a power loss during the BIOS update process and your notebook no longer works, you will need to have your computer serviced by a Toshiba Authorized Service Provider (ASP). For an ASP location, please visit the Service Locator on this site.
Toshiba recommends the following steps before updating the BIOS:
On some models, it is not unusual to see a CMOS checksum error when you first reboot the computer after installing the new BIOS. If you see this message on your screen, press the appropriate key as instructed to enter the CMOS settings. Save the CMOS data and you won't see the CMOS checksum error again.
