Hello everyone,
My Powerbook G4 400 will not boot at all! When I press the start button, nothing happens, but when I say nothing is nothing. The battery must be fully discharged, because no lights when I press the little button battery. So I plugged. I already reset the PMU as set in the FAQ of this excellent site, but it changes nothing. I greatly need a little help here. Do you have any suggestions please.??
I too have the same problem with a G4/500, test with new battery, AC adapter nine new hard drive, new memory, nothing to do, the powerbook does not start, do not start or noise or what.?? I have an adapter 550 that lights green if everything goes well and the light is red-orange. The last time I used it two years ago, everything was fine, I boot even on a FireWire drive as my internal 2.5 was released. I wonder if it's repairable and if so how much, if not already seen the original hard drive has dropped I feel inclined to drop.
I was using my Powerbook G4 400 for over 4 years without any trouble when I replaced it with an imac after some months of cabinet decided to restart my powerbook and it does nothing happened. Though I press the button the computer does not start. I tried to boot without battery, with battery, let it load 48 H, but no success. So I change the motherboard complete with a friend (motherboard change the G4 550 with the DVD by a combo of 550). After that it worked flawlessly. Then I returned to see my old motherboard G400 attempt to locate the famous battery which is HS, but I find none leaving cell. :wacko:
I do not know how to explain it, but the fact of putting "old" machine rest for a certain period has the effect of killing them. I had the same problem with a titanium 400Mhz, after a year and a half in my drawer, I came to the show and he wanted more time before starting his resting there was no problem. I tried a bit above (removed the battery memory) and after that it was willing to resume but it was hard to start, sometimes it wants more, and I had to wait some time (one or two days) before retry starting. From him, I installed a 10.4 and I served as a home server, it is on 24/24 and it must be a year since I've rebooted and it turns over again without worries. I suggest you remove the battery and just plug the mains, leave it like that for a few hours and then try to start it. If he will not remove the memory battery, that's all I can say.
Try to Install or reinstall Mac OS. The type of disk installation kit should be a valid CD or DVD for your Mac. There are several original disks Apple.
- Installation discs for Mac OS included with every Apple computer when it is delivered. These discs are usually gray.
- The software restore discs, sometimes provided separately from the installation disks for Mac OS, and applications that contain the iLife suite. - More and more often, the restoration of the iLife software is from the same installation disk as the Mac OS.
- Disks used to launch a test of the physical state of the Mac. This is called an Apple Hardware Test or "AHT." Again, the test AHT, often starts from the installation disc of Mac OS.
- Disk upgrade from one version of Mac OS to a higher version. It is in this case disk added to the contents of the box Apple sent or requested by Apple when the Mac came with a version of Mac OS already replaced by a new version on the latest Mac. These installation disks are most often named "Upgrade CD" or "DropKit CD" or similar names.
