Bios password

Hello everybody ,


I'm a system administrator at a german firm , my problem would be a couple of day's I lost half of my keepass database including some bios passwords.

Two of the computers are still in use and I would need a solution to access bios without password on two lenovo laptops B50-80 . As I read around I seen there are some backdoor passwords or something like that , I know the other solution service , the only problem the laptops are out off warranty since october this year , if anybody could help would be great.


Thank you

Re: Bios password

Hi there, Balint           -


Thank you for writing in to the Lenovo Forum - happy to have you here today.


BIOS passwords cannot be reset. The "fix" is to replace the motherboard. Still you can try the below steps:

You’ll need to move the CMOS reset jumper found at the bottom of your motherboard. Go through the HMM




1) Disconnect the power cable from the back of the system

2) Press and hold the power button until you hear the capacitors drain


Update us how it goes.
