Okay so I have a 12" PowerBook G4. Model number A1010. My atepmom gave it to me as a gift because she got a new MacBook Pro. I bought a new power adapter because she had lost the old one and I plugged it into the wall and I heard components inside moving but there was no startup chime and the screen stays black and the power level indicator on the battery flashes green whether it is on or off. Is it supposed to flash amber when it is charging? I already tried taking out the battery and holding the power button for 5 seconds. Restarting it and whatnot. Nothing is working. I her a faint humming when it is on and it gets kinda hot on the bottom while it is charging. Can someone please help?! I'm sorry if this is in the wrong section. I am new here. All answers are welcome!!!
