CMOS battery for laptop HP Pavillon ze4354EA - where is it?

Hi gurus,

I completely opened my laptop in order to replace the CMOS battery, but unfortunately I am unable to find it! Where is it located?

Is there a picture for it?
Thanks

    Hi Palmbeach,

    thank you again for your replay.
    Unfortunately there is any "silver button cell" on the mobo, **r soldere neither plugged. I'm very sorprised by this layout. Maybe I need to look for something different, but I have ** idea about what :(

    Just FYI, I do NOT suggest going to Toshiba to get the problem solved!!!
    My A135-S2386 was losing time, took it in (100 miles away) under warranty, with a "while I wait" promise. Instead I had to bring it back when they got a part (the battery) in. I brought it back -- they still insisted on keeping it, to make sure it worked properly. Finally got it back after 4 days. Clock STILL did not work, and now, lots of other things are fowled up. So now, Toshiba is on the "NEVER AGAIN" list along with dumb dell! Guess I'll try Gateway again next - they were big enough to admit their errors!

    The battery is somewhere on the motherboard. I believe it is a silver button cell. You should be able to locate it. Sorry the manual was not very helpful. I guess HP don't expect people to change it. Good luck anyway..

Hi there.
Errors 161, 192, 163.
All three of these errors are connected to the back up battery.
To resolve this problem:
1. open memory flap on base of laptop (small philips screwdriver required)
2. find the small connector with 1 black & 1 red wire coming from it.
3. disconnect above connector and gently pull the Red&black wires. The backup battery should just pull out from under the casing.
4. get replacement battery. Either
a. call IBM spares (07900 247 490 in UK) and ask for FRU:
02K6502. UK price is about £8 + £15 delivery + VAT.
b. if comfortable with soldering iron: Carefully open the packaging on the backup battery using a sharp knife.
Remove the solder tags from the battery (these are spot welded so need to be cut/broken off). Buy a new CR2025 battery from any computer shop, jeweler, or camera shop.
Using electrical tape, insulate all round edge of battery
Solder the leads onto the new battery - note polarity. Red wire to +, black wire to -.
Using more insulating tape, wrap battery so that all exposed metal is covered.
5. put new battery into laptop (reverse steps 1-3)
6. start up computer, error 192 has gone, but still shows 161, 163. Select OK.
7. reset date & time, and OK
8. when screen shows 'O / I' restart laptop using on/off switch at side.

Good luck and thanks for using FixYa!!
