(I just posted this over at [URL] but figured I might as well post it here too) My Old iBook g4 1GHz, has just started kernel panicking. it wont start at all, it kernel panics my MacBook Pro when i try to start it in Target Disk mode, and it wont boot a DiskWarrior CD, or an OS Install disk i have either. I did manage to run an Apple Service Diagnostic Test CD, and it found no errors. ive booted into Single user mode, run fsck -fy and get no errors.
I tried:
/sbin/mount - uw /
and get the following message:
"

I have an iBook 500Mhtz PPC G3, 384 RAM, 10GB HD, Dual USB. Several months ago, I opened it up and it simply would not start up. No start up sound, no noise from the fans/HD/anything, motionless. Completely dead. I've held (many times) the PMU, and tried almost anything. Is there anything else I can do to get it to AT LEAST turn on? The battery is dead, and the charger is fine, but the battery won't charge. I tested the charger on a PB G4. I'd rather sell the whole computer as a working computer. I figured I'd get more money that way. do I need to sell it for parts?
View 3 Replies View RelatedI've had my 15" MBP for just over a month, it was a refurb purchased direct from Apple. I've noticed the video issue where the top 1/2 of the screen would flash, blink. It's happened maybe 3 or 4 times. It seems to only happen after it wakes from sleep and the only fix is to reboot. I know i can switch the video card over and from what i read, it solves the issue.
Here's my question, since I can't get it to do it on demand, ( i did however record a video actually 2 on 2 separate occasions) should i take it in for repair now? will the problem get worse? or should i wait it out for bit in case something else goes wrong down the road??
Since the day I got my MBP two months ago I have always had it hooked up to a small HP HD monitor via HDMI. The other day I tried hooking it up to my 32 inch HDTV and now I am experiencing a weird problem. The TV and the Mac recognize each other but the screen continues to flash/blink every second (almost like it is loosing conenction). I check the cords and everything is fine which I assumed because everything is fine when I'm connected to the HP monitor.
View 5 Replies View RelatedEvery once and a while, usually when my MacBook is running on it's battery, the screen will show a black screen for nearly only a millisecond or two. It's not too bothersome, and it usually blinks back to normal before I can notice it, but nevertheless I don't want it, and from what I can recall, this only started happening after I installed the Snow Leopard Graphics Update. Is anybody else getting these problems on their MBPs or MBs? MacBook config details in my sig.

All I can think is that one of my kids may have trashed it but it's doubtful. What could have happened? Do I need to re-install OS?

When visiting a site that uses java my web browser blinks when ever there is an update to the information on the screen. Is there something I should change in my java preferences?
View 6 Replies View RelatedI set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?

Then tonight it just shut off instead of sleeping and now it won't start. All I can get if I'm lucky is the start up chime and a super quick flash of a white screen.

The cooling fan, that is. It had been making a noise for a few months. Today I suddenly noticed a big drop in speed even for basic tasks such as scrolling down browser window. I realised the fan was silent, so I checked with Istat, and the fan was at 0 rpm. I immediately switched off the machine. A very faint smell of burn plastic is perceptible if one sniffs my MacBook. My questions:
- The MB was active without a working fan for 5-10 mins at the most. What are the odds that I cooked some crucial part?
- If I did cook some crucial part, could a technician tell when s/he opens the MB to change the fan?
- How much should I expect to pay (in the UK) for replacing the fan?
I'm trying to figure out whether I should get a new MBP 13''. I was hoping to hold back until the next refresh, as the hardware on the current version isn't that different from what I have in my 2007 MB. Thanks in advance for your help.
My computer is a MacBook Pro running Mac OS X Version 10.7.3, 2.2 GHz Intel Core i7 with 4GB memory. Start-up has become somewhat erratic. Consistently, if I close the lid on the computer it won't restart when I reopen it. I'll have to hold the power button down for about 15 seconds, let up and then press it again. Sometimes restarting after a shutdown the computer will go through the long start-up I associate with a crash shutdown. Sometimes login start-up items don't start up. Sometimes I have to click somewhere on the screen to make the menu bar at the top of the screen visible. Overall, unexpected things keep happening. Although I don't think it probably relates, Chrome is my primary browser.

Whenever I take the hard drive out my laptop just stops working and it's back to normal when I put the hard drive in, is there a way for me to use my laptop without having to physically have my start up disk (hard drive) plugged into my laptop?
Macbook Pro can't start up beyond the grey start up screen. There's a spinning wheel and bar that moves to 1/4 before Macbook Pro shuts down automatically.

Tomorrow morning the brand new MBP 13 2.53 goes back to Apple for yet another dead pixel issue! The Staff in my local store are so, so helpful and are always there to help, but this will be my 4th pixel related return. It's a mighty fine machine but I'm beginning to feel like "that guy" who always takes his macs back!
View 12 Replies View RelatedI recently noticed 4-5 dead pixels (gray, not fixable with software) on my 1.5 year old MBP (see sig below). Definitely a bummer as I had to go through 2 MBPs when buying this computer just to get one without any dead pixels. I don't know why or when these pixels died. I have AppleCare and I am wondering if Apple will do anything about this. Is there a threshold for repairs (e.g., only 10+ pixels is repairable)? Has anyone ever got a repair/replacement for dead pixels? Is there anything I can myself to fix this problem?
View 4 Replies View RelatedI was using my macbook pro at a client, working fine.I put it in my back and head back to the office and one hour later when I go to wake it from sleep, I notice the pulsing light is not on.The battery still had a charge, so I tried turning it on and all that would happen is a brief blip of the white light and then it would power off. If I held down the power button, I would hear the DVD drive starting up but as soon as I let go, it would power off or if I held it long enough, the light would flash rapidly and then it would power off. I tried resetting the SMC controller, reseating the RAM, different RAM, and even taking the top case off to make sure no cables were loose.
View 12 Replies View Related1. Six months ago in Thailand MacBook just cut out. Rebooted and had that flashing folder with a question mark. This was all that happened. Did not have OSX discs to run check on HD. Shipped MacBook home.
2. Arrived back in UK. Now Screen will not appear, it flashes for a fraction of a second before switching off. Blank screen is all I get apart from this.
3. Changed HD with my friends from a MacBook Pro. Same thing happened, nothing basically.
4. Put OSX Disc in, now will not eject. I notice that if I let the system boot, I can' say for sure whats happening but the green lights for the capital button etc do not work. Infact I'm pretty sure the Keyboard is not working.
5. There is no sound at start up.
I had a slight spillage behind my computer. I'm not sure if any actually went into the air fan at the back but i paniced and picked it up and tossed it around a bit. Now I can't get anything from it. There is a pulsing light on the front of the computer now. Previously the screen was black but it appeared the computer was still running.

Recently it ran all the 10.4 software updates and was running fine (did some tech work on it for a friend and it was 10.4.0 to start), it worked perfectly for 1.5 weeks but today it just went black. no power ring on the power cord slot, nothing -it is like it shorted out. Is there a reset button or a reason this could have happened?

View 5 Replies View RelatedI have been having issues with my Macbook for the past 2 days. Basically it will freeze for nothing, and any soft i try to run will quit unexpectedly or it wont even start (past the Apple screen).
I ran a FSCK and it says it repaired the errors but the issues remain.
I tried installing Snow leopard, but the install also crashes.
I was told my HD might be dead even though i can still access its content 1 out 5 times i boot the computer.
I cant run a time machine (it gives me an error).
So my question is..is there a safe mode i can boot it to plug in my external hard drive to save my stuff before i buy a new HD?
Thanks !!

I have a Macbook Pro Late 2009 model, I just inserted a disc and it won't take the disc at all. Do I have a dead drive? What should i do?
View 7 Replies View RelatedI have a macbook which is just over a year old, it has been working flawlessly, however, I shut it down earlier today (normal shutdown) and now when I try to turn it on nothing happens.It is totally dead and unresponsive.The battery is fully charged, I tried another battery from my brothers macbook and it makes no difference, my battery works fine on his macbook.
I have searched online for info and have tried all the various key combinations on start up to get it to book up, but it is still totally dead.
I'm really worried that something majorly bad has happened but I don't know what could have as it has not been touched between the perfect shut down and now, I the last time I used it was a couple of hours ago.
I have owned my new MBP for less than 3 months and I have already spotted a dead pixel. It is about 2.5" about the dead center of the monitor. Whenever I have a browser or any other light background up I see it stick out like a sore thumb. I did a search on the forums and saw that Apple has a "policy" regarding these things before they will replace it. The nearest Apple store is 3 hours away and they want me to bring it in. Obviously I don;t want to drive all the way there for them to turn me away. What do you guys think....too OCD? The short amount of time I have owned it though makes me want it fixed...and I can't NOT see it now that I know it's there (yes it's a double negative).
