Replacing back up battery in G4 PB which wont recognise ethernet cable

I have an apparently working 1 GHz Powerbook G4. I took the Airport Express
card out of it to lend to my offspring. Now the G4 wont recognise that any
ethernet cable is connected to it at all. Port isn't damaged, the cable just
isn't recognised.

Tried power reset, C-O-P-R, moving eth to first place in Leopard Network
list, and am out of ideas. The date and time do however revert to 1967
whenever I leave the computer for a few days so I thought this might be a
backup battery. Apple says it is a button one on the circuit board but
somehow it defies googing on the 12. inch model?? (or I am using the wrong
term for what is called the PRAM battery on the 15 inch). Does anyone know
what battery this is and how to replace it on a 12.2 inch G4? (and whether
it can have any effect on whether the Ethernet cable is seen or not?)

1. upgrade 15" PB G4 using 12" PB G4 CD?

2. Replacing the HD in a PB G4/667/GigabitEN ?


My HD is really becoming full... can I replace it with a larger one ?

PowerBook G4/667 "Gigabit Ethernet", came with a 30GB HD (there was an
option for a slower 48GB model).

Can I replace it with a larger one, like 80GB ? Any compatibility issues ?
Then, what is the best way of transferring all the softwares from the
"old" HD to the new one ?
- Make a full image on an external Firewire HD and reload it onto the
new HD ?
- Reinstall the system from scratch and transfer all software/data ? Any
issues with moving software ?
