I thought that since this is a part that should be replaceable by the user, it should be reachable (like the memory, harddisk, you know). Guess again !
After flipping through the service manual (which I had luckily found), it seemed that there were no disassembly instructions for this battery. Looking on the blueprints of the motherboard, it showed the battery as being on the underside of the motherboard - ergo, requiring full disassembly of the laptop… wtf?!?
I’m damn glad that I had the manual, because otherwise I think getting this thing apart is not quite so easy.
Here are some after-disassembly-pics:
And here, the battery…
which ofcourse had to be of another type than the five we have in the house, so now I have to wait with the reassembly until tomorrow after I get the friggin’ battery!
