I do computer repair and have run into an issue that I cannot figure out. My customer has an iBook G4 and the screen will stay blank as if it's off even when the power button is pressed. I've tried turning it on only on AC power; I've tried Cmd-Option-P-R; I have tried applying pressure in various places. When I asked my customer about what was happening when the issue started, he said his kids were on it, the battery died and the next time he tried to boot it up, it wouldn't work. It gave him neither errors nor lines on the screen; it just wouldn't turn on. Now the strange thing is everything else works. The fans spin, the hard drive spins, and it gives the startup sound. I tried to see if maybe the brightness was to low but that didn't work either.
I have a MAC IBook (800 MHz 32VRAM) ibook and when I turned it on this morning I got a blank screen. I tried turning it off and on several times to no avail. I know the computer is on because when I touch the sound button (F5) I could hear the noise, but I have just a blank screen. I am assuming its a monitor problem or did I touch a function(s) key by mistake and it blanked the screen.
I'm trying to fix the blank screen but I don't want to use any heat. I found this method. This is the only one I found that didn't use a blow torch or such. [URL] Do any of you know where I can get a heatsink like that or if just the fins are available anywhere? I'm not sure what to search for when I do it online and I tried different variations but all the heatsinks I find have fans. I don't want to spend more than I have to since I don't need the fan. I also don't really want to buy online unless I can't find it in a retailer.
I just got this iBook 12" in the mail been to a mac shop before I bought it where the owner was told the screen had died. Motherboard was said to be Ok by the repairer. I replaced the screen with a know working one and the screen was dead. Then after the fiddle of pulling it apart again wondered if I could use the hard drive on another ibook. The hard drive I put in another iBook which loaded up fine with display. Later I tried again but it was a dead screen? Is it that both ibooks have faulty motherboards? Motherboard determines a display? Or could it be the display module? What else could cause dead screen? Cables good.
I was using my computer normally, it started to move slowly, so I properly shut it down. After leaving it off for a few minutes, I started it up again. However, every time I press the power button, it comes on and there is just a blank gray screen. No folder with a question mark on it, just a blank gray screen.
I have had my g4 for about two years and all of a sudden the thing decided that it's not going to turn on anymore. Power is getting to the machine and a certain amount of whirring is heard but not the signature! as it starts. The screen remains blank and would stay like that all night if I let it. The only thing I did differently before this appeared was to take it to work in a different bag a few times. Rucksack before, Side bag (more vibration).
Ever since I downloaded 10.7.4, a blank grey screen appears at startup. If I click on the mouse, a white square cursor appears which I can drag around and `uncover` a place to input password. Then the galaxy image appears, and I have to input password again.
I purchased a used ibook from owc in January and have had it back to them twice for repairs. Lately, it stopped booting up again and they told me to use [URL] to take the mobo out and ship it to Arizona to have the solder refloated. I did and got it back, put it together and it would boot up, only to run for 15 minutes and shut down. Thinking I missed something, I dissasembled it today and reassembled it. Now it turns on with a blank screen, the fan runs on high, and it will go no further. I tried to reset the power manager, reset the p-ram, the hard drive is only a few months old and my brain is getting fried with frustration.
My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!
My g4 ibook gets stuck on the grey start-up screen, with the spinning wheel, and then goes to a blank blue screen.When I try to perform a disk repair in safety mode, it gives me the following feedback
My brother's iBook G4 (I think it's a 2003 model) has a problem with the screen. When the computer is turned on, the screen stays black, although the backlight is on (the apple glows). Sometimes, on start up, the screen works normally for a random amount of time before going fuzzy and then black again.
Any ideas on how to fix this? Is it likely to be a problem with the hardware in the actual computer, or just the screen? Or is it a software thing?
New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.
iBook (M6411) shows a folder with a question mark on start up.
Turning on the laptop with the option key held down (for start up manager) shows the osX HD but cannot start up from it. If I try start up from a CD it works fine but disk aid does not show the osX HD.
6 month old MBP 15", been running 100% fine, plugged it into a projector the other day and it auto changed the screen resolution. I unplugged the device, went into settings and changed my screen resolution back to it's factory size as well as command & the minus key to make sure I wasn't zoomed in on anything.Â
I then did a system update for the following; Airport utility, Safari, Ricoh Printer, Digital Camera Raw, java, Itunes.Â
Restarted the computer as the updates had finished, then when turning back on the loading screen with the grey background, apple symbol and rotating loading symbol was zoomed in as much as the resolution would allow. So i restarted a couple more times, still the same thing - every time i turn the computer on the loading screen is massivly zoomed in, once it's done loading and moves to the log in screen it is fine.Â
I've tried plugging into the projecter again and editing my settings, that did nothing. It's like because i updated while the settings where wonky it's saved it somehow?Â
Info: MacBook Pro (15-inch Late 2011), Mac OS X (10.7.4), Only on loading screen!
I have an iBook g3 running Tiger that I bought second hand almost two years ago that has been working perfectly up until yesterday. I use it for uni during the day and usually turn the machine off overnight while it charges. The other night I left it 'asleep' while charging instead of off. When I came to use it in the morning it would not wake up and was totally silent although it's pulsing 'on' light in the front part of the casing was on. The charging cable was still connected and was green, indicating a full charge, but the battery-life light display, when pressed, showed only a single light, which flashds a few times, indicating the battery wasn't fully charged.
While trying to get the thing to do something I removed the battery. This caused the ibook to turn off the pulsating light - it was completely off and apparently not drawing power from it's adapter, which was still plugged in. I have been trying since then to get the computer to turn on. No matter how long it is left charging, the battery never indicates anything other than a single light with a few flashes, the computer will not turn on and the cable of the charger stays green when plugged in. I have tried inserting an older battery - which I know worked, it just only used to hold an hour's charge or so - and it will not charge at all. I have also tried resetting the PMU, which appears to have done nothing
I have a white 12" iBook 700 MHZ running OS 10.3 that startups very erratically. Oftentimes for a week or so it will startup just fine. Then it will not boot up at all with just battery power, the adapter or both. This problem started a few months ago. I've tried using a different battery and power adapter, resetting the PMU and resetting the PRAM. A couple of hours or days later it will startup again after switching around the battery and power adapter. At times when it is running with the battery in and power adapter connected to an outlet, the battery will begin running down instead of recharging it. Does anyone have any ideas as to what is going on? Is it possible the power port is defective? Or a new logic board is needed? We love this computer and would like to salvage it if possible.
I just change the name of my computer and now when I restart I don't have the login window. The computer just keep going in the Mac OS window with the blue line forever.
I just downgraded my iBook G3 600 from Tiger to Panther to see if it would increase the machine's performance. I did a clean install of Panther, upgraded to 10.3.9, and now for some strange reason, when I boot the machine (even cold) the fan comes on and constantly runs, which it never did before. However If I wake the machine from sleep the fan doesn't come on -- it only happens from a full boot-up (every time).
My iBook G4 (see sig below) has an intermittent problem. It usually sits on my desk, plugged into the power adaptor, always on. The only time I ever do a shutdown is when I'm taking it with me to the airport. Here's where the problem happens -- WHEN it happens. I start it up and one of two things happens:
1. I get the old question mark disk icon, or 2. I get a plain grey screen
Sometimes, if I do a manual force reboot (cmd-ctrl-power) several times in a row, it will finally boot correctly. The lovely grey Apple logo shows up, and all is well.Other times, when that fails, I boot from a DiskWarrior CD. Sometimes it can't see the internal HD. Other times it sees it, and when I run DW, it does find errors to fix. Yet other times, DW sees it, and finds NO errors.
When the iBook is working, the internal HD's SMART status shows as Good.So, whatup with this? Is the drive actually going bad (SMART status notwithstanding), or is it maybe the controller or some other logic board component? I could chuck the iBook and get a nice new MacBook, but this 2004 antique still suits my needs.
P.S. BTW, the internal HD backs up to an external FW drive daily, so there will be minimum heartache if/when the thing totally bites it.
I have a 4 month old iBook 12" 1.33/512/40/combo with the following problem. It went into sleep mode and never woke up. after complete reboot 1 long beep and silence. after taking the battery out and disconnect for about 4 hours I get the beep, but inbetween absolute nothing. Anyone has tips or a solution. there is no additional memory installed.
I'm relatively new to Macs and I wanted to try a clean install (or erase and install) on my ibook. I recently purchased a MBP and since Leopard is on the horizon, I wanted to do a "trial run" of installing an updated operating system. I know that you can just hit update instead of doing a clean install, but I've been reading that things run better when you do a fresh install. My old ibook still has Panther on it and I figured I could try to install Tiger on it from my MBP disks.
I know that this represents a violation of the license, but I thought it would be worth it to ensure that I don't make any major mistakes when I'm doing the same procedure with my brand new MBP when Leopard gets released. When I tried booting from the disk from my ibook I got a kernel panic which I interpreted as a sign that it was not a good idea so I abandoned the project. Now every time I try to start my ibook I get another kernel panic and I'm afraid I just broke my old computer.
