Please help with dying powerbook G3 (bronze)

Hello,

I have a powerbook G3 (bronze model M5343) that has an odd problem. If
I can get it to turn on, great, but once it's off, it won't turn on
again for several weeks (sometimes months). I've noticed that when it
doesn't turn on, the sleep led will be solid, even though the machine
was shut down, and is off. If I press the reset button, the led will
turn off, but I still can't boot. Pressing the reset button again
causes the led to be solid again. If I then disconnect the power cable
and battery (internal & external), and let it sit for a week or two,
it may power on. When it does power on, the power button won't work at
first. If I hit reset, the sleep led gives off one flash. If I wait a
few seconds, the power button will work, and the powerbook will power
up. Once it's off, repeat.

Any ideas on what I can do to solve this problem?

Thanks in advance!

I have one of these - the 333 MHz variety. I it might help if you reset
the PMU (power managenment unit) and possibly replace the backup
battery. Googling will tell you how to do all of these things.

also, you could have a look in macfixit:

When he hits th reset button and then waits 5 seconds, he is resetting
the PMU.

You might want to check the PRAM battery:

There's a switch inside the machine I think - possibly confusing this
with G4 powerbook (which I also have)

Probably you're right, I might be confusing methods with a powerbook G4
which I also have. It's be worth replacing the backup battery, as I said
before.

Yeah, odd thing about that. One of the fixes I've tried was resetting the
PRAM, as mentioned on Apple's support page. After many tries, I got upset
and left the battery out for a couple of days. When I re-attached the
battery, it still wouldn't turn on. Shortly after that, it got put in a
corner and forgotten till a week ago. I hooked it up, and after holding
in the reset button for 30 sec, it fired right up. Odd thing was, the
time was correct. Off course, I made the mistake of shutting it down, and
it hasn't turned on since. Thanks for the suggestion, though. I still
will probably look into replacing the battery (if I can ever get this
thing to power up again.)

Here's a question:

When the powerbook is plugged in, the green led on the top is lit up.
Every other time I press the reset button, the light will turn off. Oddly
enough, when it does run, the led is not on. I assumed the top led meant
the powerbook was on, but I wonder if that is incorrect. By chance, does
the led, or maybe something else, give off any kind of diagnostic codes
(like something similar to a pc's beep codes?)


Thanks in advance!

PS: Sorry, I wrote the original message on google (I was bored at work
with my dead powerbook). To avoid confusion, I'll write all the messages
from here on out at home instead.

I think he needs the whole PMU board replaced. I have a Wallstreet that
had weird power problems --- it would turn itself off randomly --- and
the sleep LED being on solid. I replaced the PMU board and it has been
much better. Before I replaced the board, I reset the PRAM numerous
times to no avail.

Well, he may very well need a new board. Is that the first
troubleshoting step you recommend?

When it has run, it's never shut itself off. Then again, the most its run
in the last 6 months is less than 10 hrs total. When your wallstreet would
shut itself off, would it not want to turn back on, or would it power right
up?

Thanks in advance!

The symptoms were very random. When it was bad, the machine would not
restart. I just get the solid sleep LED (which some have called the
"green light of death")and the fan blowing. I suspect that this is an
indication of a bad PMU.

On the PBG3's, you pretty much have to disassemble the entire machine
to replace the PRAM battery (unless the Lombards are very much different
from the Wallstreets in this respect). So, yeah, I'd say that if he were
going to go through that trouble to replace the PRAM battery, he might
as well change the PMU board while he's at it. Much of this depends on
how much it will cost him to get a replacement PMU. I got one from eBay
for $20.

Oops. I guess it is a lot easier to replace the PRAM battery in a
Lombard than in a Wallstreet:
