ED#98 : What Happens When The CMOS Battery Fails?

Dashken · 1st Jul 2008, 09:21 PM

Ever wondered what happens if your CMOS battery fails? Most of us know that the CMOS settings are retained whenever the PC is powered, but what happens when you turn off the PC? Will those CMOS settings just go poof? Or will they remain intact as long as the power supply remains turned on?

Believe it or not, no one knew for sure, so iModAMD decided to test a few motherboards and find out.

Did you leave the batterys out for the same ammount of time on each board, I was always told that all boards would loose their CMOS data after about 10-15 minutes of having no battery.

Other then that Great article

Wow, that's a special review! Thanks!

I still remember the most notorious CMOS battery ever - where they are SOLDERED onto the motherboard.

Nice pun, Mack Daddy, 386SUX processor...

Personally I once HAD a 486DX-33 system with that barrel-shape battery SOLDERED onto the board.

The most annoying part is, not more than 3 yrs after the purchase (purchased in 94) and the computer started having alzhiemer diesease, where it forgets and forgets and forgets the time, date and the other settings.

And I have to everytime auto-detect the HDD, or else it won't enter Win95... hahah!

I loved these coin-shaped batteries, they are obtainable even in convenience stores, 24/7.
