I've got a late 07 macbook pro with those faulty 8600 nvidia gpus. My macbook pro was working fine last night and now this afternoon its got a blank screen upon startup. I can still hear the chime and it still boots into the OS as i can still change the volume and backlit brightness etc.... Is it confirmed to say that my luck has ran out and the GPU is dead?
My warranty has expired and have no extended applecare + I bought the macbook in one of those education apple store. Will I still be able to get the free repairs as stated by apple and even if I do, won't they still replace the logic board with another unused faulty one and down the track my macbook pro will still be prone to that same failure?
So my wife just got a brand new macbook about a week ago, but accidentally dropped it about a foot or two this morning. The "case" which we got from macmall did practically nothing, and I think one corner of the macbook took the brunt of it.
Now, the macbook won't get past the grey startup screen. I'll see the mac symbol, and then a "no entry" (circle with a diagonal line through it) sign, and then the system will just hang.
I've used the Mac OS X install dvd to use Disk Utility to try to repair the hard drive, but Disk Utility didn't find any problems. Everything was green and good to go.
I'm running the Hardware Test now, but I was wondering if anyone here would have any ideas about what to do next, or what is causing this problem?
Update 1: The hardware test said everything was fine, too.
Update 2: It can boot in safe mode! Everything looks good from the safe boot, I've got access to all the files and everything..........................
I just bought a Lenovo Y50-70, with no operating system. Problem is, I'm not able to enter the UEFI or start the installation media in any way. I'm just presented with a black screen, whatever I do (tried every key while powering on: novo button, F2, DEL, F12, ecc...). A
Basically, turned off my computer yesterday, and I turned it back on today, and it opens the dell loading screen, then the vista loading screen, then the screen goes blank, but the light is on but nothing appears on screen,
I also can hear the vista opening music from when the sign in page opens........
also when I boot in safe mode it works perfectly with no problems ??
When i boot my laptop everything seems to start but the screen remains blank. Nothing will come up. I have taken it apart several times to make sure everything was connected and reaplied arctic silver to the cpu and vga.
My Inspiron N7010 was working fine until 2 days ago. I had it playing a movie through the HDMI port to my TV & then the video started to freeze up. Starting the next day, when I tried to start it up, it beeps 8 times & goes to a black screen, then eventually it turns off. I opened it up & re-seated the CMOS battery & checked all the ribbons. Tried holding the "d" key while powering on, the screen cycles through the colors & then goes black & powers off. Tried connecting to 2 different external monitors, could not get a picture on either.
I have an HP Pavilion g4-2149se Notebook running Windows 7.For the past 2 weeks almost, whenever I start my computer, before getting the Windows welcome screen, I get a lingering blank screen with a cursor. Then, it'll finally get to the welcome screen, but before it loads my desktop, I'll get another lingering blank screen with a cursor. Honestly, I'm grateful that my computer is still starting up at all... But is there any way to fix the lingering blank screens? It's making me nervous.I've looked around the web for a solution for days, and anything I could find I've tried, but nothing has worked. I uninstalled all recent Windows updates, hoping one of them had went wrong, but no luck I scanned for virus' and malware and found nothing. I've only downloaded one program since I noticed the problem began (4K Video Downloader), though the program doesn't seem to be a problem.
I have an issue with my Inspiron N5010 screen, it doesn't work when switching on my laptop on Battery or AC mode. It happens a lot of times when I turn on the laptop the power button, the power indicators at the bottom turns on normally and the laptop is running without any weird sounds. But the screen is pitch black even doesn't show up anything when I concentrate on it in with a lamp or any light.
When I press the power button again even after 5 mins from the start time of being running the laptop just turn off immediately and doesn't take time to switch off as If the windows wasn't loaded!
I was resolving this problem by disconnecting the AC adapter > removing the battery > Pressing and hold the power button for 20 seconds technique.but today it doesn't work anymore, If there's anything I can do to get the screen backlight to work normally ....
I have a X1 Carbon 3443CTO and it's running fine.Last night everything was ok and I went into the BIOS and changed AHCI to compatibility (don't ask me why, I was doing some testing), then I went "Exit and Save Changes" (at the last page of BIOS). As soon as I press Enter the screen freezed there (as opposed to reboot)Since it hangs there I hold the power button and it shutdown.Then I power it up again, but now, here is the problem:
1) The computer turns ON, keyboard backlight flash on for a second (normal) 2) Screen stays blank (no, it's not the backlight faulty) 3) power light turns ON (normal) 4) no sign of activities pressing any buttons, no beep sound
I recently got the Macbook for Christmas and it has been giving me no problems until last night. I was watching a video on it and I had it plugged in, as the battery was running low, when it all of the sudden went blank and shut itself off. I thought that maybe the battery had died for some strange reason, since it had not been in its charger long, went on my other computer and dismissed the situation until this morning.
When I unplugged it, checked the battery life (it was full, by the way, 8 green lights came on) and then tried to turn it on, nothing happened. I held down the button for a long time and still, nothing. I tried plugging it back in and turning it on, still nothing.
I got the manuel out and tried the Command, P, R and Power button thing, which made the laptop make a small noise. Then I tried once again to turn it on, but the screen just went to a lighter gray and nothing happened. When I pushed it again, it went dark. I tried removing the battery and putting it back in, but it still did the same, and I even tried holding down the power button for five seconds while the battery was out. Still nothing.
I've had my MBP since 1 week now, and I've been using it a lot. At first, the startup time was around 35 seconds, but recently I have noticed that the blue screen at the end of the startup process is staying for much longer than it should (around 8 seconds).
I have tried:
-Repairing Disk with the Disk Utility and the Leopard DVD -Repairing Permissions -Defragmenting (3rd party software) -Deleting the ApplicationEnhancement.bundle file using [command-S] -Deleting preference files of uninstalled programs.
But nothing worked. The blue screen still lasts 8 seconds and the pointer appears at the top left corner. The startup time is now 50 seconds, which is about the same as Windows and I don't want that.
saying that the screen of the macbook is really bad, with no specifics of why it is bad. I was just wondering if its just the viewing angles that everyone is complaining about? or is it something else?
Is there a lot of backlit bleeding on the new Macbook PRO 13"? My 13" unibody Macbook has horrible backlit bleeding. We are looking for a second computer and want to go with this notebook (Macbook PRO 13") as we love our current Macbook unibody, except for the screen which has bad backlit bleeding. Are the new screens much better? I can't find any informationpictures comparing both...
I was incidentally looking for some calibration tips for my Unibody Macbook Pro (late 2008) and I figured, why not set up a thread in which we can actually share our calibration profiles...
I've got the 9C84 which is the LG/Philips LP154WP3-TLA1 as far as Google says.
You can check your display manufacturer in System Preferences click Displays, go to Color tab and "Open Profile". In this list scroll down to number 17 which is "Apple display make and model information".
This is what Google says: 9C84 = LG/Philips LP154WP3-TLA1 (15" MacBook Pro) 9C85 = Chi Mei N154C6-L04 (15" MacBook Pro) 9C89 = LG/Philips LP133WX2 (MacBook UniBody)
Don't know about the Air, sorry.
There are quite a few people sharing their calibrations on Macrumors and other forums, I've tried some of them and frankly, they're either too blue or too bright...........
my white 13.3 inch macbook has developed like a flickering problem, its a good few years old, max memory on this one is only 2gb's. well anyways, the screen, it has only done it intermittently but when opening it for wake up, or when the screen dims, it ocassionaly does like a flicker thing, but only for a few seconds, then it stops. my guess, its the screen invertor.
i was working on my thesis in a completely dark room and realized that the screen on my macbook pro flickers even if the background is completely white. this annoyed me to no end since i have sensitive eyes, so i set out looking for a temporary fix before i try and get apple to replace my panel. anyhow, luck has it that there is a fix out there that at least temporarily stops the flicker (i havent seen it posted on nbr before, and my apologies if this is old news): press ctrl-shift-eject to reset the screen. once it goes blank, hit any key and your display should be good to go. worked for me and my screen has been flicker-free for ~30 minutes.
