Hi everyone, not sure if I am in the right place so I'll ask first to not waste anyones time: I bought myself some cheap 3rd party battery packs for my Lenovo G500 and the current BIOS version has a serial number lock and tells me those are bad and won't use them.

The vendor told me to downgrade to an older BIOS version which I can't get my hands on though so I am stuck.

Is there a BIOS/procedure available to make my knockoff battery packs work in the machine?
