Just as the title says I have a Macbook 2,1 (2.16 c2d) and after booting into osx the display shuts off. I can use the notebook as a desktop with an external monitor. Any ideas as to how i can fix this?
View 1 RepliesUpon hitting the power button, it got as far as the Apple logo screen (with chime), and then promptly powered itself down. 6+ subsequent tries have resulted in the same result; it never makes it past the boot sequence. We've tried resetting the PRAM and starting in safe mode, but we get the same result. It's also been plugged into the A/C adapter (and we've tried multiple outlets) so it doesn't appear to be a battery issue.
View 7 Replies View Relatedthe other night my girlfriends white 2009 Macbook (was updated to lion) stopped recognizing the battery. Only would boot when plugged into AC. I have other Macs so I tried different power adapters and switching in a battery that I knew was charged from another Macbook, and still did not recognize. Both batteries show 80% full or more when button pressed on battery. I moved it to my office to debug, requiring that I shut down and move the power cord. Then when I booted up, it started shutting down 10 seconds after reboot to user screen. I did the SMC reset and the PRAM resets, did Safe mode checking. Mac would still not "see" the battery or stay on for more then a few seconds even on AC. I then used the Snow Leopard install DVD and disc utilities, did a complete erase of the hard drive and reinstall of the Snow Leopard DVD. That took around 30 minutes, and the Macbook stayed on the entire time during reinstall. 1st boot after reinstall, stayed on long enogh to "set up" a user, then the shutdown problems appeared again.
Not entirely sure, as the power light on the front has been faulty for over a year, so i can not see if it is "on", but if I plug in a thimb drive, the thumb drive light blinks as if it is getting poweer, I would think thta means the computer is on, maybe the display is just shutting off? I do not have the original install discs, just the Snow Leopard 10.6.3 install DVD and a Lion install thumb drive, how can I do a AHT?

I'm facing an issue with my MacBook Pro Mid 2010. It hangs on startup and only shows a white screen with the Apple logo and an activity indicator.
I already tried:
- Replacing the HDD with a new SSD with Mavericks installed (if I put this SSD into another MacBook everything works fine)
- when trying to boot in Safe Mode it reaches about 25% in the progress bar and then shuts down
- same when I boot in Single User Mode
- when I boot in verbose mode I'm getting this output

This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart. Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. I already tried the Command-Option-P-R keys trick like five times.

My Mac Pro display shuts down on me and goes into a kind of sleep mode but will not wake up, the monitor says there is no connection. This happens during playing video games or browsing the internet on both the mac and pc side. I thought it was the video card (gt 8800) so I bought a new card through apple (ati 4870), after installing the new card yesterday the problem came up again.

I have a 700MHz iMac G3, which froze during DVD playback and it needed to be rebooted. Now it will not boot, the gray screen comes up with the loading circle, but it will just shut down after about a minute. I have reset the PRAM, PMU and it is running 10.4. No beeps or anything when it shuts down, it just turns off.
View 13 Replies View RelatedI have a 2009 iMac with SSD drive and 2TB drive.For the last 6 months, I'd get kernel errors every now and again, and I would reboot and things would be fine. A few days ago, the computer totally froze, and when I turned it on, it would shut right off. I tried booting to recovery partition, nothing worked. I took it to the apple store yesterday and they hooked it up to an external drive and then did a diagnostic test and the genius said it needed a fresh install of lion, that something was corrupting it. So we did that (for some reason though, it took about 4 tries for him to get it), and then I took the computer home and ran time machine.
Every thing worked as it should for about 12 hours, I did reboot a few times in that time. Anyways, now, it's back to where it was where I turn it on, there's a status bar on the bottom that fills about halfway and then the iMac shuts down. The apple genius said that a corrupt program/application might be causing that. I find this hard to believe ... I can understand a corrupt program crashing or not starting, but is it possible for that to not allow the computer to even turn on? The other thing is that when the computer crashed a few days ago, I hadn't installed anything new/etc .... ???

I will be purchasing the new Core i5 15" MBP in a few weeks and have been reading a lot of good things about it. With all the good things I see a few bad. I was wondering if anyone with the new MBP could answer these questions?
1. Is the Display better than the last generations? ( In particular the high res)
2. Someone said in another post boot time is slower than the 2009 C2D MBP? Can a few people confirm this?
I have read a few people say the new screens are less brighter than previous models and this has me very concerned? Of course I hope they actually turned up the brightness setting before making such claims.
Last week my macbook pro started have gray or blue screen problem, it won't boot all the time I turn on, instead I will turn into gray or blue screen and won't do anything else, the OS is to the latest version, and if it start normally it goes blue or gray screen everytime I use final cut pro, I mainly use this mac for editing videos, I try everything like safe mode, I even format the hard drive but the problem still there...
View 5 Replies View RelatedSo my old 15" early 2006 Macbook Pro (1,1) no loger recognizes the primary display. I can use an external monitor just fine, but when I go into System Profiler, it's like my primary display disappeared. I reinstalled Snow Leopard, reset PRAM, NVRAM, repaired my permissions, tried to update my mac, but litterally nothing I have tried has worked.
It started when I tried to install both Windows 7 and Ubuntu. After completing the Windows 7 installation, I restarted my computer and it just hung on the Apple logo. I could feel the fans begining to spin really fast and it felt like my laptop was on fire. I restarted my computer, let it cool down, and it hung at the Apple logo again. I rebooted it a final time, and nothing. Black screen. No backlight or image...nothing.

I have an old 450mhz powermac g4 and about a billion old sticks of pc133 (and some pc100) ram.
So I have 3 128mb PC133 memory sticks, and when i put each in the powermac individually (as the only mem stick in the computer), they work fine.
However, if i put any more than one stick in the computer, it will turn on but not boot up or display anything.
I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

I've had with my mac in a few years of smooth sailing. I'll take that as a good thing.Anyway, my Mac Mini (PPC, 10.4.11) always just recognized the exact model/native resolution for my display... One day booting up it decided to boot into 800x600 for some reason. When trying to switch back in the system pref the native 1440x900 had DISAPPEARED from the list.

View 3 Replies View RelatedI'm considering buying a used MacBook Pro (early 2008) from a seller on eBay. The seller disclosed "Sometimes the machine shuts down after startup" but adds that he does not know why.
Does this sound like something anyone has encountered and if so, was it serious?
My computer started to shut itself down without warning at around 10% battery power when my battery was bad. I bought a new battery, which works fine, but the problem persists. The computer does never tell me that battery is low or anything; it simply shuts down at 10% without warning and I can't seem to be able to do anything about it.
Info:Mac Pro
This started about 2 days ago, there was no apparent signs of such a thing going to happen.
My MacBook suddenly shuts down in the middle of my work. Shut down as in a sudden shut down, as if the battery was removed. There is no shutdown process, the whole screen just goes black. I've realized that this happens more recently when watching youtube videos, playing flash games etc.
Example : Computer dies in 10 minutes when watching videos/playing games. Computer dies in a few hours or NEVER when just typing, surfing.
It doesn't seem to be a battery problem. I've removed the battery and had my Macbook run on the Charger before, and it still died on me...

If my macbook air gets extremely hot and shuts down means that i need to take it back to the apple store?

MacBook Air, Mac OS X (10.7.4)
I have a late 2010 MacBook Air.Unfortunately, I'm in a country without an Apple store or any kind of official Apple support (no phone number to call).
2 days ago, I plugged in a little USB modem device (wireless is rare here) and my laptop shut down suddenly. It refused to restart at all until I did an SMC reset and then it was working fine (including with the USB modem plugged in).
However, the next day, the same shut-down occurred (when I plugged in the modem again) and now SMC reset is not doing anything. I've held down the start button for a very long time and there aren't any signs of life. The light on the charger shows that it is charging when I plug it in.

As of a few days ago my MacBook Pro has been acting oddly. When I shut the clamshell and reopen it again a few minutes (or hours) later it's hot and makes sounds as if it is working hard at something but the display will not turn on. I usually end up turning it off anf then on again via the power button. I have a wireless keyboard attached due to damage to the laptop's own keyboard, but use the laptop's power button (which still functions). I've reattached, and reset, the keyboard a few times in case that was the problem but had no luck. It doesn't hinder my usage of the computer once it's on again but it is strange.

I have a Macbook pro (OS 10.8.6), when I put it to sleep by closing the lid or explicitly choosing sleep option,it goes to sleep, but when I open the lid, the machine shutsdown. I have to press the power button for around 30 seconds to start the machine. In the logs I could find--Shutdown due to error code --79 and sleep failure shutdown.
