Similar to the lithium batteries in desktop motherboards? I have a customer who thinks that they do, which I think I saw somewhere, though I've never replaced one for a laptop.
 
I've seen them in a few, but I don't think they all do.

Also in some cases to might be fairly tricky to replace.

It might well worth googling the make and model of the laptop and the words "service manual". Doesn't always work, but sometime you can turn up a PDF telling you how the thing comes apart.
 
If you mean the CMOS battery then yes. The CR2032 is used pretty universally including the PS3

The large battery pack will be a bank of lithium ion cells. The CMOS coin battery I'm not sure about the technology inside, but I doubt it's lithium ion. But said battery size is used in every laptop I've ever seen inside of so a standard coin cell will work.
 
CR2032 are Lithium-Managanese Dioxide cells with a nominal voltage of 3v and will be non rechargeable. I'm not sure but I believe these are popular for CMOS use because they have a very lon shelf life.

The laptop main battery will probably be a Lithium Ion cell with a nominal cell voltage of 3.6v to 3.7v.

They are very different battery technologies and while they do share the Lithium element it's state and the other components of the battery differ greatly.
 
Thanks for the replies guys, well... I found a service manual for the laptop, although now I'm not so sure it applies strictly to this laptop I have here.

I've just spent the last hour taking the damn thing apart, removing over a hundred screws and am down to just the motherboard, with no battery insight.

Here is a picture of it:

So, doesn't look like this particular laptop has a lithium battery?

The model is HP Pavillion ze4120s ... the service manual on HP's website, under this laptop, is here.

Interesting, I'm fairly familiar with most battery types but that's a new one for me. I shall have to do some reading!

Can't see a coin cell anywhere in that image, which is odd. Is there a small panel you can remove on the bottom of the laptop it could be behind? They may have tried to make it accessible.
 
page 2-61 gives details to replace (seems the motherboard needs to be removed?)

3-19 says "Plug in AC adapter for 24 hours to charge CMOS battery." so it doesn't sound like a standard button battery

Yes I was interested to find that out too.

Lithium primary batteries, such as lithium manganese dioxide, offer high energy density, extremely long shelf life (two to three times that of alkaline), a wide operating temperature range, and excellent durability. With cell voltages of 2.8 to 3.6 volts, they provide much higher energy density than alkaline. Lithium primaries also come in a variety of sizes.

according to the manual:

Battery, CMOS Keyboard cover(page 2-13)
Speaker (page 2-15)
Keyboard (page 2-16)
Switchboard PCA(page 2-19)
CD/DVD (page 2-20
Display (page 2-23)
Top case (page 2-26)
Floppy (page 2-32)
Heat sink (page 2-40)
Motherboard (page 2-50)
Reassembly Notes: After replacing the
CMOS battery, set the correct time and
date using the BIOS Setup utility or
Date/Time in the Control Panel.

seems you need to follow up to page50 and completely remove the motherboard to access it. The battery itself might not be in a socket, but rather shrink wrapped in plastic hanging loose, but held in place with the wires. If it is one of these then you might find the contacts for the battery are also soldered or stamped to the battery, which will make replacing it rather awkward :(

So the battery must be on the otherside of the mobo if at all... ? I've followed those removal procedures up to the point of actually removing the motherboard itself.

One of them as you can see requires me to remove the heatsink which means the chip will need paste applying to it again if I leave it removed for too long ( which it inevitably will have to be )... and I have no paste or means to do that.

As well as that it's just gonna be way too much palava to remove the motherboard, it's almost welded to the bottom of the laptop's plastic case.

It sounds like it could be a rechargeable battery of some kind, going back a few years some motherboards (486 era) used a type of nicad battery that looked like a capacitor.
 
if the manual does say plug in the power supply to charge the cmos battery its likely that its a high capacity capacitor rather than a battery but i stand to be corrected each manufacturer to there own. why do you want to know ? if you really need to find out send me a email over trust and i can look at the circuit diagram for you.
 
yay. finally got the motherboard out, so completely stripped it now. And thankfully there is a small silver battery. It's smaller than a desktop battery though. Now, where to source a new one from....

its a maxwell ML1220
