Hi Prop1,
Welcome to PCHF. When you post a new thread, if at all possible, choose a forum that is most closely related to the question you have, in this case, that would be General Computing, Hardware.
I am moving this thread for you. If you have questions concerning how to choose a forum, or how to post in the different forums, please feel free to post that in the New Members forum. I am sure any question you have others will have as well.
In regard to changing your cmos battery, other than making sure the computer is off, (You'd be suprised :tongue: ) you don't need to do anything special before changing the battery.
Look forward to seeing you in the forums
TTFN
LGW
