I need to change the cmos battery in my PC but despite being told by my local Computer shop that all I have to do is take the old one out and put the new one in..I find that all the "advice " I get from the Internet tells me to save various settings before I do this.........Do I HAVE to save stuff or not is my question?..Thanks in advance...
Thanks VHG......I have NOT made any changes to the BIOS and the reason I am changing the battery is because when I shut down my PC the date and time are lost...OK when I am using the PC (if I reset the time it keeps it) ..it's just when I turn off for the night...
switch off the computer and put the cmos battery from the motherboard.
after that you can put the new battery in the motherboard .
your data will not lose.
because cmos battery is used only for to keep the time and date in to the computer.
you do not need to save any changes into the computer .only the date and time should be set again.
