BIOS makes random changes to setup
For several months my BIOS has made random changes primarily to boot order. IAt first I thought it may be a USB legacy thing as it tried to boot from my external HDD. It wasn't often and I just entered setup and put it right when necessary. I checked the battery and it was 3V+.
Recently it got worse and started not only changing boot order but also storage config from RAID to SATA.
Again it's random, not every day, not the same changes.
I replaced the battery with a brand new one 3 weeks ago and it was fine for a fortnight then it did it again today.
My wife bought a new iMac last week (WHAT I hear you say!) which is connected to our workgroup and reads the PC shared files BUT the shares disappear because despite being on the same internet time server, the PC clock is a second or so ahead. Perhaps down to BIOS? When the clocks are out of sync, the shares disappear.
I doubt the CMOS battery has run below 3V in just 3 weeks, so I'm guessing there is more going on.
Any thoughts welcome
