hi i just formated my computer and i correct the date and time. when i turn off the computer and turn it on the next day the date and time is not correct again so i manually change it and the following day it still the same. What do i need to do so it can automatically update the time and date when i turn it off and on the next day? also, the bio screen keep appearing when i turn it on.

Hi there, it sounds like your cmos battery (on the motherboard) is either faulty or flat. You will need to buy another one.

it never happen to me b4. so u saying it is the battery? i thought the battery is lifetime. Ok i give it a try thanks.

can i buy the battery in any store? or it has to be in the store?

Hi gh,

The battery in question normally does have a lifetime limit...but lifetime can mean anything - can mean the lifetime of the computer, lifetime of the "warranty"...whatever the manfucatorer wanted.

Most lithium batteries have a guranteed life of 5 years. Anything longer then that is a plus.

I think most of the batterys are a cr 2032 is that correct? in Australia I've even got the at K-Mart. I'ts a flat button battery it just clips in and out very easy to change.

thanks for all ur help that really works. hopefully it can keep working for awhile.
