It GLODs intermittently and I cannot make it work consistently.
I've had it apart about 3 times, trying various things, and unless
it is the RAM, I assume it is either the board or processor.
When the machine has power, the power button on the keyboard has no
effect. However, you can press the hard-power button on the back
panel and the green light will come on and stay solid. If you press
the hard power button again, the speaker will pop and the light will
go out. I was thinking maybe it was the AC power connection, but
the same effect was had with a charged battery.
It's been like this for about a year and I've only successfully
gotten it to boot about 4 times. If you let it sit with no power
for about 3 months, you can usually get it to boot after about 10
minutes of fooling with the right combination of taking the battery
out, plugging it in, putting the battery in, praying to the right
god, and orientating it with certain heavenly bodies. The last time
I booted it was about 2 weeks ago when I put a new PRAM battery in
it. It started up with some process that I'll call "luck", I used
it for about an hour, shut it down, and haven't been able to reboot
it since. Some time ago I tried running it with no PRAM battery
plugged in, and it seemed to work okay, but it froze on waking from
sleep, and I was only able to reboot once after that, whereupon it
froze during the boot process.
It kind of acts like a terminally fubared power manager, which I
suppose it could be. I believe there is something fairly seriously
wrong, however, as I heard a capacitor (at least I assume that's
what it was) squealing like mad when I was last trying to get the
little bugger running. I've tried it with three different power
supplies, there was no difference in behavior with any of them.
I've gone so far as to strip it down to the chassis, unseat and
reseat the processor, and do the same with the memory and all of the
internal cable connections. No effect.
So, my decision is, rather than keep screwing with it, I'm going to
just take advantage of the (really great) deal I was offered on the
list and do a 'replacement'. I've not really owned a PowerBook that
I like as much as the 2400, so never mind moving on. Actually, my
first laptop was a Duo 230, then a gigantic PowerBook 540c, then a
Duo 2300c which I really really liked, and when I finally did that
one in (actually, I just left it someplace where a glass of water
could be easily spilled in to it... then a glass of water was
spilled in to it), I moved on to my 2400c which I absolutely love.
My job let's me make use of a dual-USB iBook, which I traded to from
the 500 MHz Pismo I was using, but none of them are quite as
comfortable as the 2400.
Hmmm..did you check the fuses on the I/O and motherboards ?
Swapping the CPU might fix the problem.
