checksum invalid, check bios setup....

[krystalclear1]

Ive been getting this error on my laptop and I truly have no idea how to fix it.

Every time my laptop turns on from being off I get this "CMOS checksum is invalid" error.... and then it tells me to "check BIOS status"

If I were to update the BIOS on my laptop will that delete things off of my laptop. Also I read that I need to figure out which update my laptop needs -- How do I go about doing that?

Ive tried following tutorials online, but I don't want to accidently change something and screw up my laptop (I've done that before accidently deleting a file that I needed my laptop to run on). Please ADvise, any help is truly appreciated!
