myhart01 :
I took it appart and removed the CMOS battery for 10 minutes and it did not work.
When I put it back together still required a BIOS power up password. This Notebook belongs to a 10 yr old grandma brought to me for help at the senior center. I am a volunteer there. Switch or jumper might be it but no manual specifies where.
The old remove the CMOS battery trick does not work anymore.
Nowadays, the password is stored in Flash memory which does not need electricity to retain data. You can remove the battery for 10 years and the data will still be stored in Flash memory, unless of the memory itself deteriorates.
The best way to reset the BIOS password is to have the original owner call the laptop brand's tech support for instructions. They'll need basic info to confirm that person is indeed the actual owner.
