First take out the battery, and run it on AC power alone , if it runs ok its the battery that has died, it you still can run the laptop with orw/o a bttery then the internal power supply has died.

Sounds like the infamous electrolytic capacitor plague (see http://en.wikipedia.org/wiki/Capacitor_plague -- also read the discussion page)
In the early years of this century chinese spys stole a formula for novel electrolyte from a leading Japanese chemical company but unfortunately they only copied page 1 of the two-page recipe. The incomplete electrolyte went into many millions of capacitors reducing their life span dramatically. I understand these capacitors were made until 2004. That's about the time the G320 was manufactured, at least mine.
I opened and disassembled everything, I saw some "swollen" 1500uF/6.3V capacitors, replaced them and the G320 would start again.
This may sound easier than it was, however. I live in a country where computers aren't made no more and spare parts are hard to find. The G320 has 4 of the above caps in upright position and 4 placed horizontally. I could only get some larger types that do fit horizontally but not vertically. Thus I had to replace a bad vertical one by one of the remaining good horizontal ones and then replace the horizontal ones by the bigger ones.
If you re-assemble your G320 make sure you use the shortest 3 screws for the the points where the upper cover is fastened to the metal sheet frame that presses the cpu against the heat sink. If you use a longer screw (which I did) you may experience that a destroyed 4x56 ohms resistor network chip on the mainboard can also be hard to be relaced in non computer producing countries.
