An elderly neighbour gave me her laptop to look at. Originally W8, had been upgraded to W10. Had been working OK, but various problems a week or so ago. Tried allsorts with no success so decided on a reinstall from a USB ISO image. Said it could not find a partition. Shut down and on startup after the advent screen got a blue box asking for password. I assume this is the BIOS password which owner has no idea about. Took the base off and removed the button battery, but no joy.

Any thoughts please?

Maybe the PW is listed in the instruction book. Try downloading it.

Laptop BIOS passwords are secured in a chip on the motherboard to prevent erasure by removing CMOS battery. Other than changing the chip then nothing you can do However not sure how its got switched on on its own.

What type of BIOS is it Award / Pheonix? there are some backdoor password you could try if you know the BIOS make.

Nothing in the manual. Thanks FB - that's what I was afraid of. I have no idea what triggered it before - never seen it before. I've been unable to determine the BIOS make - nothing in the specs, and can't spot the chip on the mobo.

Finally gave up and bought a mobo off ebay for £20. Windows loaded from a USB ISO and even activated without any problems, so job done!
