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 am thinking of buying a Power Mac or early Mac Pro second hand and will upgrade the GPU myself and just want to know what PSU (watts) they have.

I was just handed down an old imac g3 400mhz desktop that doesn't power at all.When hitting the power button on the unit or keyboard, the units screen makes a noise. No hard drive or green light comes on at all. At dead silence in the room, i can hear the screen flicker, like a tv would come on. I went to go about and read a few problems before, replaced the battery and even tried a new power cord. Any Ideas?
View 2 Replies View RelatedI 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.
View 1 Replies View RelatedI have an old G4 mirror-door that I use as my PVR. It's stuffed with 4 big drives to record media, but it runs all day and sucks tons of power. Plus, it heats up the cabinet like an oven. Is there a piece of software etc. that can help the mac better manage its power consumption? I don't like using the OS X drive sleep option because the drives always go to sleep just when you need them..

If you are only running one or two applications, using one or two cores, is the power management smart enough to put one of the processors to sleep, or into a low-power mode?
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?
View 2 Replies View RelatedI 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.

View 3 Replies View RelatedI 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.
View 1 Replies View RelatedI 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.

Is there nothing that automatically sets the screen to a certain brightness, turns bluetooth and wi-fi off etc., and then adjusts it back when plugged in to the charger?
Cannot use the external keyboard's USB sockets anymore for mouse or printer. Warning says not enough power, use computer's plug. But there are none left. Tried to adjust power management.
No betterment. Can't boot from DiskWarrior CD anymore.
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.

View 2 Replies View RelatedMy girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.
View 10 Replies View RelatedSorry to mention the 'W' word, but wondering if anyone has had this issue.
Basically Apple wireless keyboard works perfectly in Windows, but the Bluetooth power management kills it after just a few seconds, which is extremely irritating. It works after you've 'woken it up' again though.
I can't find anywhere to change this, and no joy with a forum search / Google.
I have a big problem. For some months now I haven't been able to start up my Mac. It's a Mac PowerBook G4 bought back in 2002. It's a laptop. When I push the start button it shows me the grey screen with an apple. Then the screen turns blue showing the white and square icon with an apple, Mac OSX and the line for loading saying "starting Mac OS X..." When the loading sign is complete or almost complete it stops. Nothing more happens. It just stands there the blue screen with the loading line that looks pretty complete. What can be wrong? Some time ago I was asked the message: if I want to use the new way of starting up my computer, and I clicked YES, because I thought it was the normal software updating. And eversine then it hasn't been able to finish starting up. Can anyone give me suggestions of what to do? Or maybe tell me what is wrong? Maybe it has something to do with the "new starting up" message I said yes to, or maybe not.
I really hope someone out there can give me some advice, because now I haven't been able to use my Mac for months!
Has anyone had the following problem? My Macbook Pro is 2.5 years old and has recently been shutting down for no apparent reason while plugged and unplugged into the power adapter. I went to the Apple store a few weeks ago for an issue where the Macbook Pro would not turn back on at all. They had to replace the logic board. But after that, I now have the problem of the shutdowns. I went to the Apple store and got a new power adapter because mine was broken. I thought that would be the problem, but it isn't. I also recently reinstalled my operating system and the problem is still occurring. Does anyone have any advice? My laptop is a 2.2 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM. My battery is in 'poor' condition, but according to the Apple experts, the battery has nothing to do with this issue.

My G4 Powerbook 17" 1.5mhz stays on most of the time. Only thing that really gets any rest is the screen once in a while. For this reason, is it better to just power it off the powersupply and take out the battery? Any harm done in having the battery there and charging for extended periods?

View 8 Replies View RelatedI've recently acquired a (rather old) PowerBook g3 (Lombard if you are wondering). However, I have by yet acquired a power cord for said notebook.
The laptop was free, but the power cord will apparently not be so I expensive. Basically PowerBook will be used for writing papers, other non-Internet stuff I need to do this year (senior in high school). Right now I am using my iPod touch as my primary computer. My question is, should I go ahead and just pay the money for a power cord or should I just suck it up and wait until may-isu when I get a new notebook? Obviously I'd like to avoid paying a lot but would the money for a new cord be worth it? If not I could always use google docs for papers when I'm not at the house, how advantageous would having an actual notebook be
I recently tried to upgrade my powerbook with a new HD (see but forgot to format the drive before trying to install the operating system. I gave it another go last night but with the new disk installed and everything back in place, it would not power back up. I took it to bits again and checked everthing was connected including the little ribbon cable from the keyboard but still nothing. I put the old disk back in with the same results. there is no response from the power key at all. Everything is pushed home where it should be so I'm a lttle worried about what could have happened.
View 1 Replies View RelatedI have a PowerBook G4 with a broken power connector, and a brand new hard drive for my Mac Pro which I bought to transfer the files to. What is the best way to do it?- I could attempt to open the case and remove the harddrive myself, get a 2.5-to-3.5-inch harddrive adapter for about $10, and put it in my Mac Pro. From what I've read this would work, although I've never tried anything like it and I'm not sure how hard it would be.
View 9 Replies View RelatedI have a PowerBook G4 1.67 that shut itself down sometime during the day yesterday, and will not power back up. It's completely unresponsive to the power button, with no signs of life whatsoever.
I've tried resetting the PMU. There has been no new hardware or software installed. This has been tried with 2 batteries, and 2 AC power supplies.
There is inconsistency with the color of the AC power supply tip, as it doesn't seem to indicate the strength of the battery. Regardless of which battery or how much charge is left, the tip is Green, and will flicker Yellow very quickly once, when plugged in. It was Green following the initial shutdown, Yellow when I placed a dead battery in it, and then eventually turned Green. Now, it seems permanently in the Green / flicker Yellow state.
It did fully charge one battery while like this.
