I've bought my unit in a flea market. It had some problems with graphics but they've been fixed by fixing loose CPU module connector. It had Win98 installed, but it was very slow so I've reverted it to Win95.

In Windows 95 I had small problems with sound card driver (re-installation helps), in Win98 it just works.

BIOS Battery:
It is under small cover in the bottom of notebook.

0. Remove battery, FDD, HDD (remove screw then slide lock in the bottom of computer).
1. Start by removing 3 screws in the rear. ONLY topmost 3 screws, lower 2 screws are for LCD panel.
2. Open notebook and carefully remove upper cover, this one with power switch
3. You will see two screws with ground cables running to them, they are keeping keyboard in place. Remove them.
4. Remove screws labeled KYBD in the bottom.
5. Pry the lower part of the keyboard off. Remove keyboard..
6. Disconnect keyboard ribbon cable, TrackPoint plug and microphone connector. Do not destroy the plastic bolt which goes to the rear of bottom casing.
Now let's get access to the memory slots. They are slots, not sockets like in most notebooks so RAM modules have to be slided into them.
7. Remove 2 screws holding LCD panel.
8. Carefully lift the panel off and put a whole notebook in a flat surface.
9. Remove sheet of metal.
10. Remove 2 screws keeping LCD indicators, remove them too.
11. Remove left piece from under hinge. Remove screw which is keeping the topmost PCB.
12. Remove screw and right plastic part under hinge. You probably will have to disconnect LCD's connections too.
13. Now just pry the board off. Not this smallest one near fan, the large one with heatsink. Be careful when installing it back.

Assembly is the reverse procedure.
After you've assembled it back:
 -  Have you connected BOTH grounding wires?
 -  Have you connected microphone connector? :).
