cmos battery 6 years old

By jfucik ·
My old Sony is probably due for a cmos battery. How do I go about doing this? I can remove and replace the battery but I am not sure of any further procedures?

re: replacing battery

by ThumbsUp2 In reply to cmos battery 6 years old

If you make the switch really quickly, there may not be a need to do anything. However, it's always best to check.

Before you replace the battery, go into your BIOS and write down all settings. After you replace the battery, the BIOS may have been reset to factory default. At the very minimum, the system date/time will be wrong, so set it. Then, look to make sure that everything else is set exactly the way it was before the replacement.
