BIOS battery G42-415DX

The BIOS battery for a G42-415DX that I just bought used was rattling around inside the case.  I was able to coax it out through the hard drive bay but now I want to put it back in place.  Can anyone show me instructions on how to replace the BIOS battery?

Re: BIOS battery G42-415DX

Hi,

 

Unfortunately this will require a lot of disassembly as the RTC cell is clipped to the underside of the System Board - see Page 96 of your Maintenance & Service Guide for full details.

 

Regards,

Go here to the maintenance and service guide on page 86. You will need to download adobe reader to be able to see the guide.

Re: BIOS battery G42-415DX

How did you put the cmos battery back? Is it possible to get the cmos battery in place via the hard drive bay?
