Re: I sat in bios for 30 minutes and it will still shut down. it still sounds like bios setting of power management is bad.  Again I suggest reset CMOs jumper and replace with new CMOs battery.
Optiplex 7010 can't update bios, tried everything.. I tried updating bios within windows 10 and didn't work, I tried using a FreeDOS usb to update to no avail... I am running out of options as I really need to update the bios in order to fix some issues.. I also tried turning off Intel virtualization to update bios and it's still not updating.. disabled bitlocker.. So what happens is I try update bios and it tells me it's gonna automatically reset the pc to finish the update, ok that happens but all it does is a normal reset and there's no indication of a bios update. I check the bios in order to confirm and it is always still on A08 bios version. Please help thank you.
