If you’ve got an Aluminium Powerbook, (either the last of the G4 models or the new intel mac pro models) they are a great machine (the 15 inch is my favourite) but after a few years the hinge can get loose. Thankfully this is not like the old Titanium powerbooks where the hinge was broken, it is just a matter of a few screws that need to be tightened! Here’s how to do it.

G4 ibook motherboard fault.
There is a problem with the logic board in the Macintosh G4 ibooks. It can appear after a year or more in some machines and the symptom is that after being on for a few minutes, the screen goes black (it looks blank, but the light has gone off) , the fan turns on, and the computer freezes. You might think it is a problem with the display but it’s actually a problem with one of the chips on the main motherboard. This article describes the problem and how to repair it.

This is the results of a survey I conducted over a year to see what different models of the G4 ibook are affected by the logicboard fault.
The symptoms of the fault are as follows:
- After being on for a few minutes, your ibook gets a blank black screen, the fan turns on, and the computer freezes.
- You can’t do anything at all except power down the computer by holding the power button.
- You restart and it doesn’t boot up.
- You squeeze the bottom of the computer tightly together just to the left of the trackpad, and it boots up.
- It tends to boot up when it is cold, but then stops working when it warms up.
Here are the results of a survey I conducted here on macintoshhowto.com over a period of 6 months regarding the affected models. It appears all models are affected.
In this article I described the fix for this G4 logic board fault. This survey was to test what models were impacted.

I’ve finally found some time to write up the hard bits, just in case anyone is interested, so here goes. This is not for you to try at home, lest you break your ipod! Continue reading »
