I just was given a Problems PowerBook G4 1.67 15" (DLSD/HR - Al) was told it wasn't working and I thought I could fix it up. So I got this home and tried to boot it nothing no chime no lights no nothing. I did some searching around online and found that other people reported that resetting the PMU fixed this problem so I thought well its a start. I followed the directions: Removed Battery, unplugged AC Adapter and held down the Power Button for 5 seconds. Put it back together and pressed the power button. Wonders of Wonders I get the chime and see the swirling circle thing that signals its trying to load OS a minute later it shuts down. I try booting into Safe Mode no such luck same thing.
Try booting from a OS X 10.5 disc and it boots up. I run Disk Utilities and it gets done about 1/2 way and tells me that verify failed. I try to run repair and it fails as well. I boot up from another Mac using Target Disk Mode and it does the same thing. So either the harddrive, harddrive cable, or logicboard has a problem. Since I don't have the original discs that came with computer I go online to Apple's website to download the image for AHT I find something for PowerBooks but it seems to mention everything except my model. I download it and burn it anyways and it fails to work I try to boot up and it puts me into Open Firmware. I googled all over the place and everyone says that only the discs that came with this computer has the correct version of AHT on it, is this true? The next problem is I think the battery is dead. I charges to full lights but it discharges really quick. The next problem which may indicate something being wrong besides the battery is I cannot get it to power on with just the AC Adapter. Also when the battery discharges the computer powers off even if I have the AC Adapter plugged in. Now it could just simply be that the aftermarket AC Adapter that I got with the computer is not high enough wattage, (it has on it HQRP AC Adapter and what looks like a model number of N1650) When I google this I get information about about a Dell AC Adapter. This doesn't show any wattage but has the following information. Input: 100-240V~1.5A 50/60HZ. Output: 24V<insert strange symbol I cannot figure out how to add>2.65A. I tried using the one I have for my iBook that is a 48W adapter and says all the same stuff except the amps are lower and have the same problem. Do you think the battery is dead or is it possible the adapter just isn't a good match. Any help would be appreciated. I would like to fix this up but am on a limited budget.
