Where is the CMOS Battery..?

Admiral Huddy · 23 Nov 2007 at 09:27

I've had brought to me an old Toshiba 1640C laptop. The owner has forgotten the CMOS/BIOS password (he has provided proof of purchase) so just a case of locatting either the Jumper or removing the CMOS battery yeah?

Well I've had the keybaord out (a feat in itself) and had a good look inside but I can't find anything... Nothing on the Toshiba website and google doesn't come up with much..

Any help would be great - thanks

On my (old T23) Thinkpad it's underneath the main battery, no idea if that helps or not..?

Best bet would be to take all the chassis screws out on the bottom and start from there, the bios battery is USUALLY on the underside of the laptop.

i think the old toshibas used the parallel port dongel thing to remove the passwords, only available from service centres or maybe online auctions

There's usually a master password for each model. Phone Toshiba and they should be able to look it up based on your serial number.

Some Toshiba's allow you to bypass the BIOS password by holding down Left Shift during boot.

Not sure if that helps but worth a go. Also, at some point Toshiba used the word Toshiba as their backdoor password, again maybe worth a try (possibel lockout after a few failed attempts though, so be careful).
