Battery life was getting short, less than four hours.
The repair was straight forward. I read thru the guide once and completed the repair.
I cleared an area on my desk and used a white cloth (not paper) to make it easy to see the small screws and keep them from rolling around.
Two screws for the main cover are included in the kit, I would like to see the small screw holding the battery connector also included. I almost lost mine, even with the precautions I took.
I used my Beebe binocular loupe to help me see the very small parts and start the screws.
