Question about Computers & Internet
The CMOS battery is one that energises the Bios IC, when we switch OFF the system, to retain the previous status in its memeory. To replace it, you have to open the sytem. It can be located very near to the BIOS IC. A lithium disc button type battery, have 3Volts can be located inserted in a small cage. You cantake it out, and place an other battery of same type. But when you take out this abttery, all the settings of the BIOS IC will be resetted to its orginal factory settings, including date and time. You have to readjust all the Bios settings, after replacing the new battery.
So it will be best to note down all the present Bios settings, and write it on a piece of paper, before replacing this battery. OK.
