All I want to do is expose Gateway NV53 motherboard so I can change CMOS battery so the laptop can power up properly. After removing the main battery and removing the bay cover, what do I do to expose the motherboard to replace the 2032 CMOS battery? Can you refer me to some simple documentation? I have the Service Guide, but its description on page 87 of how to replace the motherboard never really explains how to uncover the motherboard..
 
Thank you. The CMOS battery seems to appear at 5:27 in white circular plastic ring just above a small green circuit board on the bottom edge just to the left of the memory that was pulled out from the bottom right. I didn't realize you would have to remove so many components to get to it.
