Bought a used Microsoft Surface with the battery trapped at 50% and a password on the BIOS.

I've tried every single trick I could Google. I've got a dozen live disks and any of them that sounded promising get trapped by secure boot. Microsoft wants me to exchange it for a $250 referb.

There's really nothing more wrong with it than the battery capacity halved and I really cannot justify $250 after just spending good money on this system.

Are there any work arounds that can help me gain full access to my property?
