Hi there! I was working on my G4 Powermac, with only one program open when I the battery was running low. I plugged it in the wall and the orange light on the little the plug that goes in the machine lit up. But the battery icon on screen didn't indicate any charging. When the orange light lights up on the plug it always starts charging! I turned it off and on again to get my work on a USB stick, but when I turned it on again it was only one 1% battery left so I had to turn it off..Now it has been plugged in for a long time and I can`t turn it on. The mac appears to be sleeping but the screen is black... I tried taking the battery out and in again.. to no change. When I test the battery level by pressing the battery-tester-button down one dot is fully and an other is blinking.. Does anyone have any tips. I had my mac for about 3 years
I haven't had any problems with this before. Where the outlet on the machine has a small dent in it and the so the plug doesn't sit as well in the machine as usual.. Someone please help me. I have a big deadline tonight.

well I took it to apple today and they took out the battery, held down the power button for 10 seconds, put the battery back in and turned it on. it work just fine and it was charging and everything in the store. then I took it home and it wouldn't charge but I moved it to another outlet and then it worked. so I don't know if its fixed or not?? they guy at apple told me that if it keeps doing that then it would have to be sent out for repair. so I just have to wait and see.
stupid computers!

I found a solution on youtube. If anyone has mentioned it already sorry for reposting.

take the back off of your G4. Lift up the CD drive and you will find a little cord which is plugged in. Unplug that cord and replug it in. Fixed two laptops which would not power on at all.

Didn't find the answer you are looking for?

Ask a question
Mine was doing this too.... I solved it by reconfiguring the battery settings.... When it's off, plug your mac in and press shift+ctrl and power button, release and press the power button again a few seconds later... If it doesnt work you probably need a new battery or something! I'm no expert but it worked for me !

Meg: Thanks for your post. I have been trying to get this powerbook G4 15 inch to boot for a month. I finally went to the Apple Store where the "genius" told me the logic board was dead. Her analysis lead to this conclusion by simply depressing the power button and stating "it does not turn on". Simply genius. She indicated that I really don't want this computer anymore because it will not keep up with the speeds of the internet today and that it was built in 2002, first generation of titanium powerbooks. I should upgrade to something newer in the store. Right. I asked her geniusness to print a list of apple service providers in the area. Our little genius could not get the printer in the apple store to print for 1/2 of an hour. Truly Einstein material here. Now I felt I could not give up on my misdiagnosed G4 friend. The problem was that it had been sitting in a closet for 6 months. All batteries were dead. I wanted to resurrect the old boy and became quite frustrated that there was no response even while plugged into the receptacle. I checked hundreds of posts all leading to nothing. Getting closer to the trash receptacle with my sick buddy I then found your post and voila! Shift+control+power button. The drive bumped and I heard that cheerful startup sound. Thank you. The genius bar really needs some help and maybe you can mentor one of two of them a month. Happy New Year!

Sorry, but your post does have nothing to do with real life, not a piece of facts, just crying. Nothing for the community, just for your ego. not worth reading it.

itzker > I think your post is really funny - the way you describe things. My g4 just chirped again after the shift + ctrl + power so everyone's happy.

Don't ever give titanium g4 up. it's too gorgeous even when it's dead.

Christina, your AC charging post has crapped out on you, a bad problem with the iBooks/Powerbooks before the advent of the MagSafe adapter. Constant wear and tear on removing/plugging the adapter wears out the charging post. You'll need to get your AC/Sound card replaced. Costs about $200 for some place like Macresq.com to do it for you. I replaced mine myself, but it's not for the faint of heart, as it takes about 20 little bitty screws of 10 different sizes to open it up and replace the part.

Once you've done that, your battery should be alright and start charging again once the adapter is being recognized again.

would you be willing to provide instructions on replacing the AC/Sound card? i've been googling & can't find anything.

Apparently reading on other forums the problem seems to be the battery. The g4 battery has a lifespan of 2-3 years and it wont hold a charge and the battery lights dont even go on. Purchasing a new battery will solve this problem.

TRY TO CHARGE IT!!!!

I have the same problem, sent that to Apple, they tried changing the DC-inboard, battery and power adaptor, without success. Conclusion: the problem is in the Logic Board, which needs replacement. Too expensive for an old computer. If anyone wants to buy it, I'm selling! Powerbook G4 17" 1.67GHz. Just email me.
