I'm going to suggest replacing the CMOS battery for the laptop (it is a button type battery inside). Here are two videos which should help with doing that https/www.youtube.com/watch?v=ITEYHPQMXGQ and https/www.youtube.com/watch?v=3OouOALZus8 the first shows the battery better.
The drawback of my suggestion is that I could find no CMOS batteries for that model from a few searches I did.
