BIOS setting keeps switching from AHCI to RAID?

Question

Dell Optiplex 9010 which is new to me. I got it and in the Bios the SATA setting was on RAID and it wouldn’t boot. Switched it to AHCI and all was well. But now every time I unplug the PC, it goes back to RAID! Also says something about date and time need setting. Could this be the motherboard battery is dead?
