PowerPC :: PowerBook HD Or Logic Board Options - Rotating Loading Icon?
Jan 26, 2008
I have a 17" PB, 1.33 ghz with 1.76gb ram. In September it gave signs of the hard drive failing. It would crash right after booting and then not boot at all.If I booted into target disk mode i could still access the files. I backed everything up and did many versions of trying to reformat / reinstall my OS to no avail. When Leopard came out I went through the process again to see if that might help but it didn't. Today I replaced the HD and now it still won't boot at all. It goes to the grey apple screen with the rotating loading icon and stalls. I've let it sit there for 10 minutes or more.

Hoping that some of you here still own or have owned Powerbooks recently... I have a PB G4 1.67ghz that I bought in July 2005. Since then, it's seen the back of the Apple Store several times to replace three logic boards, a screen, and a SuperDrive, with the most recent instance being the third logic board replacement. This has left the future of my laptop in uncertainty, as the warranty expires this July. In the past, I've owned several Macs for 5 years or more, including my beloved G4 Cube, so I'm no stranger to sticking with my Mac until it's absolutely necessary to upgrade... and financially, I was planning for this computer to last me another 2 years before I had to upgrade.

I'm still working on this deal to buy a used 12" PB. The seller says that she just replaced the logic board, hard drive, and battery. Now, I see this as a negative. Obviously the computer was having problems, she spent a bunch of money fixing it, and is now selling it anyway. What do you think? Is it a negative that it had problems and needed to be fixed? Or is it a positive that it has a brand new logic board that will theoretically last longer than an original one?

I bought my first Mac (iBook) last December. However, it is now dead from logic board failure. I was looking at Macbooks but they are very expensive, which is why I bought the iBook in the first place. So now I'm looking at 15" PowerBook G4. My question is: If having a G4 proves too difficult in the next few years (PowerPC compatibility and speed), could I put a logic board from a 15" MBP in the PB?

my G3 iBook's logic board has died (it was in that series that had the logic board problem). I had it replaced once already when it was under warrenty. However, the second one has died and Apple will not touch it (unless I pay something like $350 for Apple to fix it). Well, I decided to take matters into my own hands and I ripped open my iBook piece by piece. Now that I have the logic board in front of me, what can I do to fix it? Can I sodder something? Should I take it out and buy a new one off ebay?

last week I started to get scrambled video on my iBook G3 (2002 vintage) running 10.2.8. I got it to start up correctly before freezing twice in the last week, but it appears to have given up completely today. I'm not as concerned about this as I would have been a few years ago, since I have a lot of experience with similar problems. Apple replaced the logic board under AppleCare in 2003 and again in 2004, and this is part of the series of iBooks that Apple was fixing for free for a while as part of a class-action settlement. Apple doesn't appear to be doing that anymore (that's fine, the computer is Old with a capital O and it's not feasible to continue supporting the product), and I assume that this has effectively totaled the computer

I had a fault where my powerbook would not start up. Apple replaced the logic board and now the screen is a very strange colour and flickers.In the video I use the hot corner and the dog changes to the right colour but the windows do not. its very strange.I will have to take it back to apple in the new year but is there anything I can do to improve the image. Its so hard to look at like this.

I'm having my pb repaired from my casing warping. I brought it and the and they agreed to fix it. He ordered the parts and said when they arrive they would call me to bring it in. I guess they could do it at the store ( )i'm surprized it wasn't sent out. ne woot on the order sheet it says "Board, Logic, 1.5 GHz 64MB VAM". Now my question is I did a BTO and upgraded the VRAM to 128. Did he order the wrong part? Will it still work?

My girlfriend has a 12" G4 Powerbook that she claimed was getting really hot. I noticed it was as well, so I installed iStat Pro and saw that the fan was spinning at 0 RPM. So obviously something is wrong. I read a few posts on people having problems with the logic board, which would also cause the fan not to work. However, the computer runs fine, the fan just doesn't turn on when it gets hot. I haven't (and don't plan to) let it get so hot that it would shut itself off or burst in to flame or whatever happens. I understand it's out of Applecare, but I would prefer to fix it myself on the cheap. I'm perfectly capable and willing to replace the fan, but before I crack it open I would like to know if there is a simple way to see if my problem is simply a dead $30 fan, or a $500 logic board.

I recently took my 15in 1.5ghz powerbook to an AASP and was told that my logic board needed to be repleaced. He quoted me $369 and told me the turn around was going to be 4-5 days. I asked him just to be sure: This would include a logic board replacement and would only cost $369? He confirmed that it shouldn't cost more than that. Being the creature of habit I am I decided to take it to a Genius Bar for a 2nd opinion. My appt is tomorrow and I decided to research it further before I went. I have read other reports claiming that Apple charges upward of 500-800 to replace the logic board. Does anyone know if the replacement for the logic board is supposed to cost that much? I don't expect someone to know exactly but I was wondering if anyone has any reports or experience with this.

I have a powerbook g4 15" 1.5Ghz. My VRAM is shot and my computer keeps on going into panic mode or gets hot and just stalls and I have too reboot manually. I just purchased another logic board off of ebay, yes I'm a very brave guy, I installed the new/used logic board and I now see that the ribbon cable recepticles for the keyboard and finger pad are not on the new logic board. Obviously I bought the wrong board. Is it possible to still use it somehow like buy a new top plate or buy an external keybord? The top plate I have now has the fat ribbon cable and also the small one. Can I just get the proper cables? If so which ones are they?

I've searched high and low for any and all alternatives to working with my, shall we say, "experienced" Powerbook Titanium, despite it's age(it's not old, it's chronologically advanced!). After looking things up and being able to think of nothing, I figured I'd finally register here and hope for some good advice from people who possibly know more about Mac hardware than I do.I received my laptop in June of 2002(it was likely bought either that month or April) from my father. As far as I was aware, it was a brand new Powerbook bought from Comp USA...with the latest specs and peripherals at the time. After 7 years of using and loving my laptop(despite the fact the battery is completely dead, both hinges are broken and removed to keep the wires from accidentally being cut until I can afford new ones, and the CD drive no longer working), it's come to a point where I'm needing to try to breath even a little new-found life into my true love...or be stuck using "The Rex", my overbearing Desktop PC with its snooty Windows XP and massive noise-creating fans.

I came across a powerbook g4 (dvi, 15 inches, 800mhz, 512mbs, airport card, dvd-rom + cd-rw, after market battery never used and after market ac adapter)) sold "as is" on craig's list. I picked it up for $50. It had everything but the hdd. The first time i plugged it (without hdd) I got the flashing ?. I swapped in another hdd and all I would would get the apple chime followed three soft beeps (nothing on the screen). And then eventually, I would power it on and the only sign of life I would get is the caps lock light on, and the num lock light only if I hit F5 (again nothing on the screen). If i let the powerbook sit without the battery for a while, then I would get the apple chime again but then the power cut out right away. This happens with the adaptor or the battery only which leads me to believe it's not the dc-in board. I have tried different ram, disconnected the airport card, disconnected the cd player. I have tried resetting the PMU and every key combination to reset the PRAM (it never seemed to make a difference).

I'm looking to get this titanium powerbook but it has a broken screen, possibly bad backlight? I can get it for a good price and I would love to have it to replace my ibook. I don't know the specs for sure but I am positive I think it's the DVI version since it has the keyboard that looks like the ibooks(same placement for the keyboard release latches).The guy said it worked fine on an external monitor but just recently he said it won't boot now and it now makes a high-pitched whining sound. Anyone know what that is? I'd like to use it as a headless mac until I locate a new screen for it.

Love my 12" PB 1.5ghz. Running Leopard on it. But the memory cap of 1.25gb with 256gb soldered on to the board (and only one memory slot) bugs me. Especially since this is the same logic board that goes into the 12" iBooks last revision that have 512mb soldered on to their boards. (Their memory cap is 1.5gbs and it does make a difference, especially on the 1.42ghz iBooks).I just asked Gary Dailey of Daystar if they could solder a 1 gig chip on the board.. seems like a better "upgrade" than overclocking with Leopard's memory demands Will let MR know if this can be done. If so, i'm in.

I was using my trusty powerbook 500 mhz and when i closed the screen while the machine was on, after @ 1/2 hour i opened the screen up and NOTHING!. i restarted and nothing again, the caps lock key will light up, so i am assuming the power supply is ok. No chime and black screen, any suggestions on what it might be...im thinking logic board, if so what ones will fit that model

I have a PowerBook G4 15" 1.33GHz that up until now ran flawlessly. Today I was watching a movie on it with some friends when it randomly shutdown. Since then, it no longer turns on. The battery is fully charged and there is no problem with my AC adapter. With just the battery, nothing happens when I press the power button. When the AC adapter is plugged in and I press the power button, the optical drive spins at full speed for a few minutes and then the PowerBook shuts itself down again. I have attempted reseting pram and pmu with no success. I think it could be a dead logic board but I'm not sure. Would it be worth the money to buy a new logic board or should I just part it out?

I was given a free G3 Pismo Powerbook. DOA and traced to dead internal battery. Successfully replaced and the unit is now alive except I have determined the video chip is toast. Everything works except display to all output types is shot - bad colour, vertical lines, huge cursor etc.
Lots of logic boards available on ebay for about $30. This would make a decent starter computer for my young boys.
I'm looking for good instructions to replace the board.
SPECS
Pismo Bronze Keyboard
G3, 400 Mhz
512 MB ram
10 GB drive
DVD ROM optical drive
2 USB + 2 firewire 400 + S video + RGB

so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.
i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.
i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.
the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.
i cant find anything on that model, except for on ebay.
and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]

Would it be possible to get a logic board with a 1.33ghz or faster processor out of a 12.1" G4 and swap it in to a G3? Are the parts even compatible? I know from building engines that certain years and parts are interchangable but I don't know about computers.

I'm looking fore some help/opinions on a friends iBook G3 800/30GB/256MB/10.2.8the problem is- when you press the power button, it powers on and you hear the (all is ok) chime. now sometimes it will boot perfectly fine and others you get nothing, just a blank screen.Now i know these things were notorious for logic board failure, but could this just simply be the HD, and if it is, how easy is it to change.

As the title implies, I've got 3 year old G5 iMac sitting as a paperweight at my desk. At least half that time ago the logic board died and I was quoted a repair bill of around $900. I couldn't go with it, but I couldn't decide what to do with it either. I now have to get rid of it and since I know that this model had lots of issues with logic boards I'm hoping some of you will have some good advice.

I've got a 900mhz G3 iBook that my wife uses. The logic board was replaced on it once already. It's really starting to act up again. I see Apple is still honoring their Logic Board switch out. What are the chances they'll upgrade it to a G4 or a macbook ? Has any recently sent there iBook in for a logic board replacement? How'd it go, how long did it take?

Can you put a 800Mhz g3 logic board in 700Mhz g3? I read somewhere that I will have grounding issues. Is that true? Has anyone done this? My ibook has been sitting here unused for the last 4 months and I would like to see if I could get it working. (The video chip has died and I have tried to get it back)
