PowerPC :: 12" G4 Powerbook Fan Replacement Or Logic Board?
Nov 18, 2007
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.
My 17 inch iMac G5 1.8ghz seems to have died. For a while it's been refusing to power up and then powering up randomly but now it wont power up at all. I've looked on the logic board and reset the SMU etc but I can only get the first LED to light up. I think this means the logic board has died. Is it worth replacing the logic board and can it be done easily myself? Or should I just bite the bullet and pay out for a new alu intel iMac? I'm in the UK btw, any ideas on logic board prices?
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?
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?
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.
the two logic board (motherboard) of the MackBook Pro and PowerBook G4 looks very similar, but i do not have two side by side in person. this idea was tossing around in my head, so what do you guys think ? has anyone done this swap ?
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 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 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.
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?
After my MacBook Pro 2.5's logic board failed( and was replaced under AppleCare) after owning my MBP for just 17 months, activity monitor often shows asl ( system log file) manager at about 100% CPU. Fans spin at 5000rpm. Never had this issue before the logic board replacement. Also, Safari 4.04 frequently crashes; never had this issue either before, either. Occasionally, after restarting my MBP, the Apple doesn't appear on my screen but instead I get image of a folder alternating with a question mark. When trying to use installation disk to start up, under 'select the system you want to use to start up', Mac OS 10.5.8( the OS that's on my hard drive, will not show at all...it's missing. After restarting several more times with installation disk OS 10.5.8 eventually appears as a selection. Why would these issues appear only after the LB was replaced. I suspect that the replacement logic board or its installation is not 100%. Something's not quite right there.
I have an A1260 that looks like it's undergoing the problems repaired by this program: [URL] However, I've had this thing apart, replaced the hard drive with an SSD, the optical drive bracket is very bent from when I replaced the optical drive, my display bezel is cracked in two places and held up with duct tape, and it generally looks like hell. Will they still repair the logic board despite all the other, ahem, modifications? I could probably put the original parts back in, but despite that it will be obvious I've taken it apart. It is and was out of warranty when I performed these. Should I take it to a retail store or just call Apple and ship it to them?
I have a Rev. A 1.83ghz MacBook which my partner uses. In the last six months we have had an increasing number of problems with it. First, there were the intermittent sleep problems: delay going to sleep, failing to wake. Then it killed three batteries consecutively before Apple replaced the sleep switch and power connector unit (thank heavens for AppleCare). That was back in July. Now the same problem has recurred: the battery is dead and fails to accept charge. Got a call from Apple yesterday to say that they've switched out the logic board and that the item is ready to collect.
We have eight months left on the AppleCare and what I want to know is: 1) What exactly can we expect from a logic board replacement? Do Apple really have a stockpile of 1.83ghz logic board's floating around in case someone needs a replacement or is there any chance of a processor upgrade with this repair?.............
I got a mac mini out of warranty (core 2 duo 1.83 ghz) that just died on me. I went to the apple store and they sent it in for a diagnostic. They confirmed that the logic board is dead and will be around $350 to replaced. I'm still weighing my options and was wondering if anyone can direct me to a site that sells replacement logic boards to see if I'm better off doing the repairs myself?
Last week my friend gave me their macbook for free and told me it had a fried logic board. I took it just because I wanted the learning experience. I'm a freshmen learning engineering, so if soldering/de-soldering is needed I should be fine. I'm wondering how to figure out what is wrong with the logic board, ie. if it got water damage because I was thinking maybe I could try to get replacement components for the logic board. Also it came with a 60gb hard drive, but I was wondering if I could upgrade that. I know I need a 2.5 sata drive, but I was wondering if iIhad to get the hard drive from apple or if I could just go on newegg and buy any hard drive that has 2.5" sata connection.
My Early 08's 8600 failed recently (was still working but I got like 10fps on games and it failed the test) so I had it replaced at a few apple stores (an ordeal and frustration in and of itself). Anyways I was wondering if I need to do anything since the logic board has been replaced. Is a format necessary (for optimization and speed and for compatibility)? When I turned on my computer it gave me a warning about my clock being set to March 20, 2000 and a Y2K compatibility error. Should I be worried? All in all everything seems to be OK - unfortunately since my MAC addy changed I can't access Time Machine backups anymore and have to start a new backup
My white late-2007 MacBook recently had its logic board repaired, and ever since then, some weird things have been happening with it. The first and most annoying thing is that connecting my external display (HP w2338h) to use my MacBook in desktop mode simply does not work like it did before. I'll connect the display, make sure mirroring is turned on, shut the lid of my MacBook, but instead of going to sleep, my MacBook will just shut off.
I'll disconnect the display and open the lid to turn it back on, and it then proceeds to show me the regular Apple boot screen...but with a status bar beneath it that I've never seen before. I've attached a picture of this. Forgot to mention that I did once get the external to mirror my MacBook, but that when I did, the picture quality wasn't quite as sharp as it was before the repair. I tried reconnecting it, and haven't been able to get it working since.
I recently had a problem where my 13" 3 yr old macbook would just blink off. then it became shorter and shorter until it would not start up. i brought it to apple who told me after inspection that it had liquid damage and the battery connector and logic board needed to be replaced for an astounding 800+ dollars. the book only cost me 1100!! i got the book back (obviously i didnt pay that, i am sane!), i fiddled with it by trying to start with just the battery. no response. with the battery and charger. starts for just seconds. and then with just the charger. walla! starts up and runs like new.
I'm going to the Apple Store on Wednesday to most likely have my logic board replaced. To those who have had this done, how long does it normally take?
Also, if they determine (for some reason) that this repair is not under warranty, will they call me first to tell me so I don't get a huge bill?
As a side note. Where are the water sensors in the 17" MacBook Pro. I haven't spilled anything on it, but I have used it in some humid situations, and I fear that some of them may have been tripped erroneously. I don't know why I fear these sensors so much, but I just do.
I have an ibook g3, 500 with os x 10.3. I bought it a long time ago in Germany, so it has a German keyboard. Yesterday I replaced the logic board, since my ibook showed signs of the well known logic board / graphics failure. That went well, graphics are working now. But, suddenly the hardware or the os does not recognize the keyboard anymore. I can not type in anything at the log in screen. No lights are working on the keypad as well. Funny thing is, that, when I hold down the apple key at the start up, this works and will get me into the start up options screen. So, I am not sure if it is a matter with the hardware or with the os.
Another thing I recognized: when I put the computer to sleep at the log in screen, the sleep led will light up, but then the ibook will immediately wake up. - This might be connected to the keyboard problem. I bought the logic board replacement in the US. Could this be the problem? Does this logic board probably have trouble with the German keyboard? Or, do you think the logic board replacement is broken as well? Would using an American keyboard help?
