TiBook 400 sleep woes

At about the same time, I started to have sleep problems with the machine.

I'm a lurker who needs help with a TiBook 400 mHz. It's been a good, solid machine ever since I got it. Recently, I upgraded to 10.3 and replaced the hard drive with a 60 gig. At about the same time, I started to have sleep problems with the machine.

A lot of the time, but not always, it will not wake up after falling asleep. It will sound like the hard drive is starting up and the other associated "I'm awake" noises will commence, but the screen remains dark. If I try to restart, often it will not restart. It will either give the chime and then hang with the screen dark (but the HD sounds like it's spinning) or it will get to the apple screen and freeze. Once, momentarily, the folder icon with a ? came up but then it progressed to the apple screen.

Sometimes it'll start up just fine.

It never crashes while I'm using it. If I set it so that it never goes to sleep, I can use it for hours with no problems.

The system software has been reinstalled twice. I put the old hard drive back in and still experienced the same problems.

The local repair shop says it's probably a bad logic board and possibly also a bad modem. Altogether, it could cost me over $500 to fix and it's a fairly old machine, so I'm looking for second, third, fourth opinions and you guys have always been great for this. I'd love to buy a new PB but I just can't afford it.

Any ideas?

Thanks, Melanie

Check your RAM. If you've got aftermarket RAM installed, try removing it. Software RAM checking utilities may or may not successfully detect problem memory. OS X will choke on RAM that seems just fine in OS 9, so it's not a case of works or not, but more subtle.

IF it's not the RAM, then it does seem likely to be something on the logic board. (but I'm no expert on TiBooks)

I have a TiBook 400 running 10.3 as well. It doesn't have the sleep problems you describe. So, my guess is that it's not the OS X 10.3 and the TiBook 400 being incompatible.

If I try to restart, often it will not restart. It will either give the chime and then hang with the screen dark (but the HD sounds like it's spinning) or it will get to the apple screen and freeze.

This by itself would suggest a hardware problem.

I also have a WallStreet I 250 running 10.2.8. Last month it had random shutdown and not restarting problems. I swapped in a different PMU board and that revived it. It will still sometimes not wake from sleep, but that's pretty much a known issue between OS X and WallStreets.

I don't know if the TiBook has a separate PMU board or the PMU is just part of the logic board.

Have you tried resetting the power manager??

-R.

I don't think so either. We reinstalled the system software twice just in case there was something wrong, but it didn't fix the problem.

Yup. Doesn't fix things.

My computer is currently in the shop and will probably need a new logic board, and possibly a new modem. The RAM checked out fine. Thanks for the help. I was wondering if there were any obvious or well-known problems that could be causing these issues.

The repair is going to cost around $500 but without the funds to buy a new computer, I guess I have no choice but to fix the one I've got. I plan to save up for the G5s that I expect will be out next year?
