It works well, but "zzz" noise is very annoying!
Opening the case, I found there are four big fans and a small one in it. The noise came from the small one, which is on G400, not from the other four big fans. How can I get rid of the annoying noise? Just try, try, ...
Disassembling the fan, I found there were some dust on the ball-and-roller bearings - that's the problem. So I blew off the dust and put a little oil on it (just a little); then assembled and installed it. Turn on the computer, the noise has gone! It is as quiet as a one-fan-machine.
Go to IBM website, download some updates. Refresh the BIOS, G400 firmware (after updating, the RAM becomes 16M, I think another 16M is for the other display) and CDROM firmware. Now the computer is like a brand new one.
