Powerbook suddenly sleeps, will not wake up!

it's getting hot in here

Thanks for all the suggestions. I too feel upset by this issue, which I as able to remedy under extended warranty. However I have to agree with some of the sentiments above. To quote Apple themselves:

Your toaster doesn’t crash. Your kitchen sink doesn’t crash. Why should your computer? Think of the countless hours you would save if your PC worked on your time — not the other way around. Then think about a Mac.


If you spend more of your precious time figuring out why your PC crashes than you spend taking out the garbage every week, you need a Mac. Still not convinced? Just ask the millions of people who use and love a Mac why it’s become such an integral part of their lives, and most will tell you the same thing: it just works. Letting them do what they want to do. When they want to do it. All the time.

That’s because a Mac offers absolutely flawless integration of hardware and software. Only with a Mac do you get a system built by the same people who make the OS, applications, and the computer itself.


Take a Mac out of its box and you experience that hand-and-glove fit from the get-go. Plug it in. Turn it on. And you’re ready for anything. With a Mac, you’ll find all of the essentials built right in. USB. FireWire. Ethernet. Every new Mac comes with built-in antennas for wireless networks, so getting on the Internet from anywhere is a mere matter of turning on your Mac. No reconfiguring your network settings. No plugging in some clunky wireless card.

The real secret behind the Mac’s crash-resistant performance lies deep within the operating system itself. Beneath the surface of Mac OS X lies an industrial-strength UNIX foundation hard at work to ensure that your computing experience remains free of system crashes and compromised performance. Time-tested security protocols in Mac OS X keep your Mac out of harm’s way. Most Fortune 500 companies, governments and universities rely on UNIX for their mission-critical applications. And now, so can you.


Of course, should you happen to experience the occasional hiccup with your Mac, you won’t get the runaround. Because Apple makes the whole enchilada, one phone call — or better yet, one visit to the friendly Genius Bar at your local Apple Store — can solve both hardware and software problems in one fell swoop. And when you add the AppleCare Protection Plan, you extend your support options to include three full years of free telephone help and comprehensive repair coverage. That ought to save you some time and sanity, too.

Good luck to all those who have either PowerBooks or MacBooks, whether or not these issues are related or not is perhaps fudging the issue: there is I think something underlying this issue, which it would appear requires the user to be a complete computer expert and able to afford and predict any problems, it's somewhat unrealistic. In hindsight the AppleCare is totally necessary, but as these machines are so expensive, it is becoming almost too expensive to own and run a Mac. Pity. The squabbles above - which are both personal and pointless are not helping. In my timid viewpoint I think there is an issue here between shutdowns and sleeps. I hope you guys look out for yourselfs. Creativity shouldn't have to cost so much.

Hi all with the latest Powerbook 15" 1.67GHz.
I've had mine for exactly a year.
I am making video documentaries with FCP. My huge frustartion is that I have to get my next film done and........

In the last couple of weeks my laptop started going into sleep mode despite preferences set as never sleep either with power or battery.

Sometimes it will wake up if I press the spacebar several times. Sometimes it will not wake and I have to take out the battery, press the start button for several seconds, replace the battery and have to go and set teh year etc yet again?

wow, the same exact thing happened to me a few days ago , I have done every thing mentioned on this forum and did this:
cd /
sudo mkdir kext.backup
sudo mv /System/Library/Extensions/IOI2CLM7x.kext /kext.backup/
sudo mv /System/Library/Extensions/AppleLM7x.kext /kext.backup/
sudo rm /System/Library/Extensions.kextcache /System/Library/
Extensions.mkext

and then reseted the nvram.

unfortunately non of these things help and I've been told that I need to change my PMU.

Does this mean that i have to get a new logic board or can I buy the PMU separately ?

Cheers,

Toki

You can't get the PMU separately. However, I can almost guarantee you that the PMU has nothing to do with it, so buying a new logic board would be a waste of $800. If it's the thermal sensor failure that nearly everyone else has, you need a new topcase (~$200-250) which includes working trackpad hardware.

My anient Powerbook 17 titanim sleeps still

I caanot wake it up. I restart the machine and everything seems fine, then suddenly the black screen. The number lock lights come on and the caps lock key will light up, but I cannot get it to wake up for anything. I have tried a few things to get it to work but nothing helps. Once, I did something where I was typing in stuff like the computer was a pc in dos mode. It was crazy, it did not help. But I did find out that nothing was wrong with my screen. I believe it is software related. I have read the posts above and will try a few of them. I wanted to see if this problem is similar to what has been decribed in previous posts or if someone has experienced this specifically.
