hi.
i have with me an old computer i been asked to install ubuntu in but there is no way of doing anything before i get pass a bios password. which they have forgot. also there is something strange about the keyboard not responding to input at all and it cant just boot from cd. it is correct to assume the only way is to remove the bios and put it back in after a good five minuttes right. i do not want to destroy anything .
thanks.

If you want to reset the BIOS, remove the battery and leave it out for 5 minutes. Put it back in and boot your old machine up and see if it's still asking for a password to get into the BIOS.

Disconnect the PC from the power and there should be a link to the bios battery (probably a CR2032 button cell) on the motherboard, which you can remove and then reconnect after 5 minutes. Hopefully that should do it.

i can not spoil or destroy anything by doing this can i?. i done it once before on my old computer and it went well but i also seen my brother having to buy new motherboard from playing too much with bios updates .

Hey,
Like everyone said above, remove the BIOS battery and leave it out. However, don't put it back in for ATLEAST 30 MINUTES. I've left it out once for 10 minutes and it didn't work. The info in the BIOS needs to clear and it can take up to 45 minutes. And no, if you take the battery out, it will not ruin your BIOS. Just be sure to mind the + and - when you're putting it back in.

Good Luck!:)

There may be an option to stop anything writing to the bios or boot sector in the bios settings. Make sure that's turned on.

@Kevbert: I doubt if he will be able to access the BIOS if he's lost his password. Accessing the BIOS requires a password and he doesn't have it unfortunately. I hope that the battery fix will work.

Just a warning regarding the IBM Thinkpad series. I lost my bios password, and removed the small internal battery to "reset" the bios.

But instead I got a message that the computer has been tampered and was now locked.

Now my T41 was worthless without the bios password.

But I found help here:

www.allservice.ro

I downloaded some programs and built the simple I2C programmer/reader.

I managed to read the contents of the eeprom and decrypt the bios password to get the t41 going again.

Much trouble for a lost bios password, be sure to keep your bios password.
