Green means the battery is fully charged. Orange is charging. Sometimes these machines will not start up with a fully drained battery, they need some charge before starting. Plug it in. Hit the start button and go take a shower. When you come back it should be booted up.

No light will not come on. Power adapter works. I unpluged it for being away for 4 months. Upon return pluged it in. NOTHING HAPPENS

Any suggestions??

Same here kept my PB for longer then a month as now can't start, Done everything is suggested here. Kept is plug for more then a over night charging. Still didn't charge the battery or started with mains on.

Please Help.

I have had this kind of problem too where my charger is fully OK and the battery works too. Even though the battery last for just 30 mins max. The recieving point of the charger does not accept taking in electricity to the G4 PB. I tried to open up the keyboard cover in order to clean the reciever. The charging process takes alot of warmth and makes the metal in the recieving part on the computer a bit dirty. In kinds of makes a layer of dirt/flame/electrisity-burn on and this layer is making it difficult for the elerctrisity to come through. I cleaned it up yesterday and the charger worked ok for a while. But the same thing happened again this morning and I tried to use a spray soap bottle and a toothpin to clean it again but it didnt work. Probably because of the soap and water still keeping it wet. You should wait until it get dried.

Update

But what other options is there to solve this problem?
