Lenovo B50-30 BIOS password problems following BIOS update 9CCN35WW

Hi. I have a Lenovo B50-30 mode 80ES. It was set to require a password on startup starting with a capital "A". While experiencing charging problems, amongst other things, I updated the BIOS to 9CCN35WW, downloaded from the Lenovo support site.


Since updating, the laptop no longer asks for a password on startup (No big deal, I applied a windows password), however, when pressing F2 to access the BIOS (which I need to do, the F keys are the wrong way round), it asks for a password, When pressing to strike a capital A, the laptop beeps and doesnt enter it. It wont accept capital letters anymore, therefore it wont accept the pre BIOS update password.


I have referred the laptop to Lenovo service, including returning the laptop, and they have been nothing short of useless. They said they couldnt repair it under warranty because of "Marks, cracks, inappropriate treatment" and it would cost £255 for a replacement system board. I really couldnt see why I should pay for an issue created by their support system, so I asked them to return it unrepaired. Upon arrival, the laptop was immaculate, so I dont know what damage they were referring to.


Is it possible to downgrade the BIOS to a pre update revision, to change the password and then reset it to one the new BIOS approves of?


Thankyou in advance.

Hi AndyP1972,


Welcome to the Community Forums.


About password issue as declared in the hardware manual (page24) here:


"If no master HDP is available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either the user or the master HDP ... .


Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee."


As suggested here on the same discussion, removing password and resetting BIOS defaults before upgrade are advised and that passwords are user induced scenario that Service Centers do not cover under normal warranty as they usually replace the entire systemboard instead for a fee.


Installation of new BIOS may be blocked by initial BIOS password lock for it to proceed so I am not optimistic that it would work. You may check if maybe an external USB keyboard works on this situation.


Update us how it goes.

The password is based on key location.  Capital and lower case are the same.  Try lower case.
