Hello all my ACER TC-885-UR19 keeps reverting back to RST with Optane in my BIOS. I have removed the optane stick in the m.2 slot and replaced it with a Samsung 970 500gb m.2 drive. I also got rid of the hard drive that came with the computer. The computer reboots around three times and then gives me the option to go into the BIOS where i manually change it from rst with Optane to AHCI mode. when i f10 and save it, it reboots in AHCI mode and runs fine. When i shut down the computer and power it off i have to go threw the same procedure all over again. How do I get it to not ever go back into RST with Optane mode ever again? Thanks for your time in advance!!

    Are the time and date also out of sync? If the bios information is not being saved, it may be necessary to change the rtc battery.

    Well I had a few of those batteries around, and put a new one in. You were right! Saves my Bios settings now. Funny this computer is not that old I am surprised the battery went out that quickly. Egydiocoelho thank you very much, and take care!
