cmos battery location

[Navy75]

I have recently did a clean install of win7 from xp and since then have had to reset the boot sequence.  After some searching I realized that the cmos was not retaining it settings for date/time, etc.  After booting through the recovery process the win7 os works find.  I have downloaded the manual but have not been able to positively locate the cmos battery under the keyboard.  My laptop is a HP Pavilion zv5000 or zv5260us.  I would like some direction as to its location, if it is soldered in and  is replaceable?

Also, I would like to upgrade the primary RAM from 256 to 1GB.  The secondary was already running 1GB.  Is this a possible upgrade?

Any help would be appreciated.

I actually used to own a very close model to that and can vouch that it can use 2 gigs of DDR 800 SO-DIMM (first gen DDR). One slot is under a door on ther bottom and the other is under the keyboard which is not too hard to remove. Here's the Manual:

I see nothing in the Manual about the RTC battery or its location which leads me to believe it is soldered to the motherboard.

Thanks for the information.  That confirmed what I had thought.  Since my last posting I have located the cmos battery, under the key board, but tucked under the mount plate for the mother board.  It looks like it will require a complete disassemble to replace.  What I have found on the internet is that this particular battery is soldered to the mother board but is replaceable. 

Is there a way to confirm the actual charge condition of the battery without removing?

Not really since you can't get a meter on both sides but if she will not keep date or settings that is about all you need to know.
