Yw😌. If it doesn‘t keep time or date, it could really be the CMOS. Good luck 👌

I’m no expert, but have you tried to change the CMOS Battery? After I haven’t switched my laptop on for some time, it would bootloop 3-4 times before turning on. Changing the CMOS battery did fix it for me.

Same. I recently changed the battery on my 6 year old laptop. Works still fine. No need to buy a new one

And often less harmfull than alcohol
