Lenovo BIOS Keeps changing

I have a couple of Lenovo V110 laptops with windows 7, the only way for them to work, is for the BIOS to be set to Legacy, however, the BIOS keeps reverting back to UEFI which then causes a boot loop as it can't find the hard drive, it's driving me nuts! I have tried changing BIOS batteries, and updating everything, but it still keeps happening!! Has anybody got any ideas on why the BIOS keeps changing!!!

Did it save legit? Maybe a Bios update could help.

Yeah it saves changes, cause I changed something else to see if that would stick which it does, and I've already updated the BIOS, I've been Goolging for days and I just can't see anybody else with the same problem.

Could it be that the MOBO is dead?
