Just resurrected a dead 5300CS!

[switch998]

Last week, I bought a powerbook 5300cs that wouldn't power up, according to the owner, for $5 locally. Figured it just needed a new power jack. Turns out pressing the reset button would sometimes yield a green light only, a chime and then freezing, or just some noise from the speakers. I took the laptop apart and found no obvious signs of any damage, but when I looked closely at the processor, I noticed that one side of the processor's pins broke free from the logic board!

Anyway, I resoldered (by hand ) all of the 603e's pins, and got the machine up and running again. Since I figure the heat from the processor caused the solder to crack in the first place, I applied a little bit of thermal paste to the chip.

Hopefully this helps anyone that has a powerbook with similar issues

Hahaha I just reached for the "Like" button. Gotta spend less time on Faceborg.

Well done Have you ever done any soldering at that pitch before?

Baby that hard drive...one of mine just gave up the ghost, and it was quite a chore refitting the drive sled to take a 12.5" factor drive from a 1400. The originals for the 5300 were these weird 17mm drives with holes in different places.

Congrats on the successful resoldering!

As a matter of fact, yes I've done micro-BGA stuff by hand (Well, the stencil part) in the past too. Just an FYI, you can make a decent buck on eBay through repairing macs.

Either way it was pretty damn frustrating, and it was a decent amount of work, but I would have hated tossing the powerbook.

Should have just gotten the reflow nozzle on your BGA station and did it that way. Thats what I do.

I was too afraid to burn the chip, and I wanted to put new solder on the pins, so the reflow station I have was not going to work (theres on way in hell I'll ever lay solder paste correctly).
