You might try looking for a similar or same series notebook at
http://repair4laptop.org/disassembly_fujitsu.html

However, most if not all notebooks/motherboards have only one on-board backup 3Volt cell. If you've already changed it with a KNOWN GOOD cell, and it "didn't work" to fix your problem, then the problem likely isn't the cell itself. But then again, it also depends on what the problem is.

Perhaps it would be better to describe your exact problem.

- thx for the link - i will try this
- battery is 100% ok
- problem is that the computer doesnīt start without prompting,then you have to press F2 etc...and you have to change time, date etc each time you start the thing
- i suspect where is more then one battery built in as in this german forum one post says:

Are you basing that on the last post in that link? All the other links referred to only a single cell, and I think that last post's reference to connecting the batteries (plural) was referring to the coin cell AND the main battery.

I think there is still most likely only a single coin-cell "battery" on the motherboard.

However, many years ago some computer manufacturers used a time/date module (a dedicated time-keeping integrated circuit module) on the motherboard that contained its own internal, NON-replaceable battery (good for about 5 years), and they used a separate cell or battery for the CMOS memory. But that was back in the days when some manufacturers also still permanently soldered-in the motherboard CMOS memory cell/battery rather than providing a lithium cell-holder. I suppose the dedicated time/date modules may be still used in some "single-use" electronics packages (e.g. trackers, weather balloon transponders, etc) but that's being supplanted by GPS data.

But, it's hard to believe anyone still uses those on consumer motherboards.
