Laptops :: Why Powerbook Going To Sleep?
Aug 9, 2009
I have a Powerbook G4 that I bought used a year ago. It has worked perfectly with no problems at all. Yesterday it started going to sleep randomly during use. It would wake up when the space bar is pressed and be fine for a while. This was happening every 10 - 15 minutes. Since yesterday it has gotten worse and worse, happening more and more often, and now it won't even stay awake long enough to click on something. Any ideas of what could be wrong??? I'm sorry I don't know what operating system or anything, I'm not all that Mac savvy.

I have an iBook G4 (14-inch screen, 1.42 Ghz.) and it has a cracked screen. I also have a PowerBook G3 PDQ (14-inch screen, 233Mhz.) with a good screen. Question: Can you swap the screens even if they were made 7ish years apart?

I have a very old PowerBook that did have OSX running on it fine. Recently it has stopped working completely and when you startup it takes you to a blue screen with a question mark and a finder icon flashing on top of a folder. If you give it long enough it will just shut off. I have tried booting from a CD but I can't seem to get that to work. I boot up holding down the option key and it brings me to a window with a picture of my hard drive and a picture of the CD drive but when I click the cd drive and then click the forward button it merely acts like it's refreshing the list and doesn't actually boot from the CD at all. I've also tried holding down C during boot up but it ignores that and just goes to the same old flashing question mark and finder icon screen. The CD I am trying to boot from is the same OSX cd that I originally installed OSX on this computer from so I know it works.

We have about 10 PowerBook G3/400 computers in our school running OS 9.2.2. They haven't been used in a couple of years and now none of them will boot up. No power. I checked Apple's website and found an article called Power Management Unit. It says to hit the reset button, wait 5 seconds and then hit the power button, but it didn't work for any of them. Does anyone have any ideas?

I just acquired a 1 GHz 15" Powerbook Ti. It is in good cosmetic condition except for a few dark marks from the keyboard on the screen. I can feel them with a fingernail, so I know they are residue from the keys. Is there any way these can be removed without damaging the screen? I have had very good results using toothpaste and a damp cloth on other surfaces, but I am leery of using even a very mild abrasive on the screen. I have even used newsprint on some sensitive surfaces with good results but if you make an error on the screen, it is either permanent or expensive. I suppose I could try in a corner but I know there are anti-glare coatings on the screens and I could make things worse. This is most noticeable when there is a light-colored area displayed right under the marks.

I recently inherited a Pismo, 400 mhz and a 6gb hard drive. Other than the tiny hard drive, the computer is in great shape and has a lot of service left in it. I was able to load Tiger on it, and it's working fine. I replaced the hard drive with a 100gb Seagate, but when I tried to format the disk,the new hard drive didn't show up during installation attempts. However, the volume was visible in the system profiler and the disk utility...I reinstalled the original hard drive, and that booted successfully so I guess that means I didn't damage the hard drive cable, which I had feared. Does anyone have an idea about this? So odd that that I could locate the drive in the disk utility but not at the installation screen.

My Titanium powerbook was running when suddenly the screen went crazy, flashing colors and bars, then went blank black. Now can't boot at all, even from external drive. If I hold down the start key I eventually get a faint humming sound and the little "alive" light at the bottom of the display bezel flashes for a short time. If I repeat this it takes at least 15 seconds to happen. I have turned it off for a while and even removed the battery but nothing changes. Can't afford a new one, need help to fix it.

My 1999 PowerBook G3 "Lombard" does not start when I press the power button. Is there a way to force it to start without it, or do I need to get a replacement button?

My Friend has a 15" Powerbook (2nd last rev.... 1.67ghz with lo-res screen) and it's been on the fritz lately. It operates completely normal and then it suddenly goes to sleep. When I wake it up it's back to normal just fine. It goes to sleep after about 3 minutes of use.

My PowerBook had a battery problem (dead battery which did not charge anymore). It lost date and time several times while mac was on AC and power cord was removed. Now it has a brand new battery.
Since then, Powerbook does not go to sleep mode anymore:
- if it goes to sleep following settings of energy saver prefs, it doesn't wake up anymore, black screen and LED stays on
- if I force it to sleep through the Apple menu, it freezes with a black screen with the following white text: You Mac needs to be restarted by pressing for a few seconds on the power button.
I have tried to reboot with apple-alt-P-R and waited 5 reboot
I have tried sudo pmset -a hibernatemode 0 in the terminal
Nothing changed...
Any (good) idea out there???

My G4 PowerBook (Aluminium 15" 1.67Ghz, A1104) keeps putting itself to sleep at odd times. This is without a main battery in place, and a dead PRAM battery, both of which I'm waiting to replace.When I wake it up, it tries to power up, HD spins, but then goes back to sleep without even the screen coming on. I can do this like 5 or 6 times, and then eventually it wakes up and stays awake. For a while.or the first time today it wouldn't actually even start up from a total shutdown 2 minutes revious. It was just dead. After about the 6th press of the power button it started up.

I had an iBook, now I have a powerbook. Both have the feature when I shut the computers and they are in sleep mode, the light goes from dim to bright to dim to bright..... It drives me nuts. I have to put my computer in a drawer or cover it up at night. Does anyone know how to turn the light off? or have it be constant? Is there a download that fixes it?

My G4 Rev E PowerBook won't wake from sleep. The battery died and the computer slept, but now when I boot it, it gets to 3.5 progress bars and freezes. I have tried rebooting but I can't seem to get out of the resume from sleep mode.
Any ideas? It doesn't show the grey Apple screen like it does from a fresh boot, just the progress bars that show up when the battery dies.

My powerbook g4 has started to go to sleep while i'm working on it. The problem has started some time after i have updatet my system to leopard. I have checked the heat sensor and the one at the trackpad has problems in showing the temp all the time. Furthermore it sometimes vary from 4 degree c to +100 degree c. This looks odd to me since it only occurs in periods.

I do NOT want my Powerbook G4 AL 15 to go to sleep when I close the display lid. I want to manually put it to sleep when I want to and have it run with the lid closed when I want it to. What should I type in the terminal?

I was wondering how/where the sensor is/works to tell the computer to go to sleep when the lid is closed. I am doing some mods (discussed in the marketplace forum) and would like to try to keep that sensor intact if at all possible, but i realized I have no idea where it is located or how it senses that the lid is closed on these.
I searched the forum a bit and found nothing, and can't find anything in google other then sleeping problems... unless I just am horrible at googlin.

Recently my powerbook g4 aluminum 15" won't wake from sleep mode, and i can't turn it off with the button. When the computer does turn off the only way i can get it back on is to open it up and reset the logic board by disconnecting the back up battery for a little bit. I've tried reseting the PMU,

When I try to print from my Powerbook G4 to my HP 6500 wireless printer it will not work. I have found out that if I turn off/on the printer then it will print. So, it must be an issue with the computer not waking the printer from a sleep mode. Anyone have a solution to this that doesn't consist of me turning off then on the printer? I have tried to reinstall a few times with no avail.

I've a problem with my PowerBook G4 (12-inch DVI and Mac OS X 10.4.11). When I close the lid or when I manually try to make it sleep from the apple menu, it goes into sleep mode put only for 1 second and then shuts off (crashes). So instead of being able to wake up the computer, I have to boot it up from off.

I am leaving for a week long trip and many parts of it will not be able to run the computer off of the powercord, which is a problem because I get about 40mins of wordprocessing use out of it when I run the battery alone. Can someone explain what the significance of these levels are for my Powerbook G4 15'' (Alm) 1.25GHz, namely the cycle count and full charge/remaining capacity?
