cmos battery

jassi_9

Hi the time and date on my computer has gone out of sync

and i get the warning when i boot up "cmos battery low"...

what kind of battery do i need to buy to replace it? are they generic for computers or specific to motherboard + voltages etc?


finally where is a cheap place to buy one?....ebay?

thanks

open up the case and look on the motherboard , you should be able to see it , looks like a 10 p piece , round and silver , read the number then get one from Maplins

straight swap when you get the new one

Usually a CR 3023 in a standard desktop PC, available everywhere for less than £2. e.g. here

You've gone numerically dyslexic, espresso! Normal type is CR2032...

[edit: but then that's obvious from the link you posted, which says CR2032...]

their site gives some good advice too

once you have changed the battery you will have to go into the CMOS setup to restore your settings. the default settings usually work ok then teeak as required.
