Quick! Will a laptop thinkpad 600 boot up without a cmos bat.

[Kaieye]

I have a dead laptop and I removed the cmos battery and it does not boot...

Yes it will boot without the BIOS battery.

Nope, it wont. You will get 2 constant errors until a working cmos battery is in. Unless it just doesnt turn on at all then its probably just busted.

... which you can bypass, if my memory serves me correctly.
I'm thinking he means POSTing, however.

Never got around it on a ThinkPad. You need a battery.

Can't bypas on the 600 series, even if you enter the correct info, on the next reboot it will still crap out. Trust me. I have about 20 of em at home.

As others have said,
Depends on the laptop.

Most
Toshibas
Compaq's
HP's
Sony's will boot with a bypass without a cmos battery.

Understood, but he's said that it's busted; i.e. not POSTing. If it's not POSTing then how would he reboot it?

I think he's saying that it's dead to the world, he's tried clearing the BIOS by pulling the battery, and it won't boot. All that, to me, says lack of POST

Perhaps... but ThinkPads are notorius for failing post due to bad CMOS battery... replacing it is the only way to be sure.
