HP Pavilion N3390 Laptop CMOS Battery Location

Guest
Hi,
I have replaced the RTC/CMOS batteries on some of my
old laptops, and it is a big help if I know in advance the location
of that battery.

I failed to find the location of this battery on the web for my HP
Pavilion N3390 laptop. Note: I was ripped off at www.eservicemanual.info
when I was misled with their claim to have a service manual. What I paid
for turned out to be a user manual (I already have).

I will be very grateful to anyone who can tell me the location of the
CMOS battery.

Thank You in advance, John

I would have thought that this battery would be a user replaceable
item, in which case it should be identified in the user manual.

If it's not a user replaceable item, then perhaps it is integrated
into the RTC/CMOS RAM IC. Do you see any "fat" ICs?

That takes the fun out tearing apart a laptop.

I couldn't find any useful docs for something that old. Nothing on
the HP web pile.

I have some photos of a similar HP N5250 laptop:

I don't see the battery in the photos. As I vaguely recall, it was
under the touchpad and I had to remove the palm rest plastic in order
to get to it. I should have some similar antiques in the office and
can check tomorrow (time permitting).

Hi Jeff,

I did not disassemble my laptop yet, but if I knew that the
battery is somewhere under the touch pad, that would be very
helpful. If this was my only laptop, I probably would have found
it by now. Fortunately, I have other laptops I can use in the meantime.

Thank You for your help, John

Sorry, I forgot. I just checked the junk pile and there's nothing
similar to be found. I'm afraid you'll have to open it up and look
around. Look under the various trap doors on the bottom first. Look
under the battery. Although my photos show nothing under the
keyboard, look under there anyway. Those are the usual hiding places.
However, if those fail, my best guess(tm) is under or near the
touchpad. Good luck.
