Re: lenovo L540

spbios and SMDFlea are absolutely right. If you only want to reset your Lenovo L540's BIOS password, you need no new BIOS flash. The SVP is held in the chip SMDFlea's picture helped me to locate. Though the chip is a P24S08, it is so tiny, that only "08 -1 EL" is printed on it, so it's hard to recognise.

To reset the BIOS password you have to short legs 5 and 6, as others have already stated. [B]Timing is critical.[/B] If you short them too early, the laptop won't boot. If you short them too late or for too long, you'll get the password prompt....
