PowerBook G4 Aluminium disassembly?


Well-known member
Yes, I've seen the guides and it seems to be a long and tiresome process.

One of my G4s are having overheating problems, and after resetting the pmu with no succes, I consider opening it to have a look.

Any experience?

made one good out of two bad units.

Was painful...

many screws all around, most of them not of the same size, spent a whole afternoon.

I use a cupcake pan (or two) to help keep track of screws.  Helps make it slightly less painful.

IFixit has guides, with numbered steps. Make a numbered grid on paper and put the screws by step in the appropriately numbered grid space.

I once did this surgery on a 12” PowerBook G4 and it was not so very bad, honestly.

A lot of these powerbook g4's have a small scratch line or detaching just above dvd drive. Its best to pull back that slightly left center clip properly to avoid damage to the case.

I just replaced the logic board in a 15-inch Powerbook. I usually grab heavy card stock and fold some packing tape over and stick it down stick side up. That way, I can stick the screws down in the order and arrangement they were removed. The fiddly little hook that secures the front of the palmrest above the Superdrive slot is a bear to remove though. Be patient with that one. I also didn't reconnect the optical drive cable correctly and I'm reluctant to open it back up to fix it. Take your time.

I used the iFixit guide.  Kept the screws for each stage on separate card, clearly marked for position.  Slow and steady, and you'll get there.

They're not bad, they just take patience. If you have ice cube trays or an egg carton you can use them to hold the screws. Marking where they went isn't a bad idea either.

iBooks are way worse.
