MBP black Screen after Sleep Mode

My MBP goes to sleep but I get a black screen and it won't wake up after pressing keys or mouse. The only way to wake it up is to hold the power button down and restart. The white indicator light stays on and it sounds as if the computer is running, but nothing will wake it up. Can anyone help?

I have the same problem. It doesn't happen all the time, but sometimes when I open my computer after it has been sleeping, the screen will not come on. The only way to fix it is to either hard boot it, or press the power button, then enter, then press the power button again after a bit. The latter tells me that the computer wakes up, just not the screen as I can correctly shut down the computer with key strokes. Mine is an Early 2008 (non unibody) MBP.

Black Screen after sleep mode, and even after restarting

I've had problems with black screen before, usually after sleep mode. I usually then restart the computer, the sound of turning the computer on is heard and then it is working perfectly...however since last night I tried to restart it, the sound of turning the computer on was heard at a lower level of volume, but the black screen is still there...I have disconnected the computer, taken the battery of the MBP reinsert it, plugged it and turned it on. It worked once, but it is no longer working...PLEASE HELP!!!!!! SOON!!!! I have projects to turn in in a couple of hours.
By the way I have the Snow Leopard OS system

Mbp running slow after sleep mode

My MBP runs extremely slow after sleep mode (closing lid). It seems like Safari will take up much RAM. But I use a memory freer which supposedly should solve the problem. So after all I am not sure what is the real cause and what could solve this.
BTW it runs normally after a reboot.
Mine is a mbp 13" refurb purchased in March, 2012.
Processor 2.4 GHz Intel Core i5, 4GB RAM

I too have been noticing problems in slow behavior after sleep mode. It has gotten so bad I have been restarting it regularly or shutting down much more regularly. It behaves almost like normal after a re-start.
It is almost like the hard drive is failing? Last time this happened I put a new HD in. I am usually running a large number of different programs, always multi-tasking, which has been a mac fortie. Seems worse with the last few updates. My I mac is 24" imac 2008 model. replaced drive just before apple care expired.

Black screen after sleep Mavericks security update 2014-002

I get a black screen for about 10-20 seconds on waking from computer sleep/display sleep after installing security update 2014-002 for Mavericks. The computer is awake, because I can click and change windows, pointer/cursor placement, etc., from before the time the computer went to sleep. Never had this problem before this latest update.

If the resets don't help try the following in order as necessary:
1 - boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and repair both the disk and disk permissions. Reboot normally and check for improvements.
2 - boot into the Recovery volume (boot with the Command + R keys held down) and reinstall the system.

MBP Black Screen after software update

This is posted also in OS X.6.8 forum:
Hello to all, Just after dowloading today's latest updates, iTunes, Safari, something about file exchanges and Apple remote I beleive, there needed to restart and once done, no chime and black screen...
All was perfectly fine just before, and I did backup beforehand.
Tried to reset PRAM, restart in Single user, Safe mode, Installation Disk, all with no success.
I will let it powered off and let it cool down for a while if it can help, but it was not particularly hot when restarted.
Any other suggestions ??
Many thanks !!

Hi Clinton,
Thanks for your quick answer.
Actually, I'm using 17" version as I've last check the version was OS X 6.8.
I did pressed buttons to see if it works behind, I believed it works there's light in caps lock, makes noises when I pressed the sound button and esc button.
I did pressed the light F2 still NO DISPLAY.

Black screen during sleep mode (10 second lag)?

Okay, so I love my Mac and I freak out every time I notice something weird. Call me crazy.
Macbook Pro Retina (Late 2013) OS X Mavericks 10.9.4
Whenever my Mac mac goes into sleep mode (idle) and I try to reach my log in screen, a blank black screen shows up. I can move the cursor around however, it takes 10 seconds for my user screen to show up. I restarted my computer and it's doing the exact same thing. Should I be concerned?

Blank (lighted, but black) screen with cursor at bootup
[SOLVED] - Macbook Air Sleep/Wake problem
Dark screen on start-up can only see curser

Help! Stuck on white screen after sleep mode and won't start again!

Bought the iMac last week, updated to 10.5.1. Worked well until this morning after I did a security update. Then put it in sleep mode - and basta! After I wanted to work on it again - it didn't restart. So, I had to switch off using power button, but it never started again and always got stuck on the white screen with the Apple logo and the rotating loop. Tried to repair permissions - cannot do it, as it says there is an error. Tried to re-install from DVD the Leopard while archiving the previous information - can't do either - says error. Now trying to re-install it again with an erase option. But this is not a good option, people! This is pretty very much disappointing, Apple!
Can anyone help, please!

Boy that is way too bad.
Could you tell us what the error message was?
While sometimes the error messages are not very informative, other times they are. That might be a clue as to what is going on.
When you restart from the DVD you have the option to access Apple's Disk Utility and repair the disk.
You might want to try that, skip repairing permissions at this point.
You can also reset the computer by unplugging all cables including the power cable for at least 15 seconds and then plug in the power cable and keyboard and restart.
You can reset the PRAM by holding down the command-option - p - r keys simultaneously during restart and waiting for the startup chime then releasing those keys after the second chime to allow the start to continue.

Again getting black screen after Exiting Safe Mode in Windows 8 as suggested by hp

I'm again getting black screen after entering safe mode after upgrade to Windows and exiting from safe mode but after exiting my laptop display was of 8.b but after some time it again went back to same black screen problem .I disabled Intel and amd hd 86graphics driver in safe mode.please help .

Hi there ,
Thank you for visiting the HP Support Forums and Welcome! I have looked into the issue you are having with your display Turning Black after entering Safe Mode. I found a document for you called Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot. It would be very helpful for me to know what has been done already so that I can narrow down what troubleshooting would be best for you. You mentioned in your post "again". Is it an intermittent issue? Please follow these provided troubleshooting steps, re-post with the results of the steps in the document, and any other troubleshooting steps you had tried and the results. Have a great day!

No video after sleep mode.

Brand new home built system (all new components unless noted otherwise) running Windows 7 64-bit Home Premium on the following hardware:
MSI X58 Pro-E motherboard,
Intel Core i7-920 (2.66) CPU,
Enermax PRO82+ 525W powersupply,
Sapphire ATI HD5670 1GB GDDR5 PCI-E video,
8GB Corsair 1333MHz RAM,
WD Velociraptor 150GB 10,000 RPM boot drive,
WD 500GB Caviar Black for file storage,
Plextor DVD-RW,
CoolerMaster case.
Older Viewsonic VP2030B monitor,
Older Microsoft Desktop 6000 V2 keyboard/mouse.
With standard Windows 7 power saving features enabled, the following
intermittent problems occur:
After the system has gone into sleep mode, the video card provides no signal to the monitor. Moving the mouse or touching keys on the keyboard obviously bring the system back out of sleep mode, but no video signal is received. Unplugging the DVI-D
cable from the card results in the Windows sound indicating a change. Plugging it back in, results in a Windows sound indicating the change. This happens when you unplug one end of the cable, it doesn't matter if it is at the monitor end or the video card
end - as long as the other end is of course still plugged in. The only resolution to this "no video" state is to reboot the computer with the power or reset button.
On some occasions when turning the PC on, there is no video signal. The system boots properly (although the BIOS screen takes about 15 seconds to appear - something MSI says is OK), and can be shut down with the correct keyboard sequence. The monitor
runs through VGA, DVI-A and DVI-D, but no signal is ever received so it goes into standby mode.
When the computer boots properly, usually while it is still loading Outlook (which is set to start automatically), the screen goes completely blank for 5 or more seconds, then comes back on and the monitor menu indicates that it is running at the correct
resolution, and then the video works correctly from there on in - unless it goes to sleep.
On some occasions, when recovering from a "no video after sleep mode" incident, everything on the screen has been moved towards the upper left side of the screen. The Outlook window which is normally quite large (80%) and centred on the screen has been reduced
in size to about 50% and shoved into the top left corner. Also, the 4 gadgets that normally run vertically along the right side of the screen have been moved up and towards the middle of the screen, one or two of them often overlap others.
Things I have done/tried:
All Windows 7 updates,
All motherboard BIOS updates,
All video card drivers and software updates from ATI,
Replaced the DVI-D cable,
Uninstalled the video card and drivers, and moved the card to a different PCI-E slot,
Replaced the video card with another Sapphire ATI HD5450 card (temporarily).
Sapphire thinks it's a hardware problem with the original card, but since temporarily replacing it with another card, the problems continue, so I doubt that is the issue. (Plus I have to pay $25 to ship the apparently defective - under warranty card - back
to them.)
These problems have happened intermittently since the system was built in January 2010 and they seem to be quite random, sometimes not happening for weeks, other times happening every few days. Sometimes the system is in sleep mode for 1/2 hour and it happens,
other times it is in sleep mode for hours and it happens (or doesn't).
Any help would be appreciated.

Hi again,
OK, I finally got around to trying this. I still have to check if that actually fixed it, but I managed to get into the "Factory" OSD screen.
I had my system running, disconnected my new monitor and plugged in the flaky old Viewsonic. I then:
1. Depressed and held down the #2 button, then depressed and held down the Power button,
2. Almost immediately the amber power light turned-on, the backlight turned on and the output image from the PC showed up.
3. The On Screen Display (OSD) for all the monitor setting came up (at the bottom of the screen instead of the middle where it normally is), and underneath the Main Menu window in the OSD, along the bottom of the overall OSD window, the word "Factory" appears
in the middle between the control button keys (#1 for exit, and #2 for enter). (It's not normally there.)
4. Using the down arrow key on the face of the monitor, I highlighted the "Factory" menu item, pressed the #2 key and voula! there was a whole new simple white text on bright blue background window, which among all sorts of settings included "Factory Reset"
(which is the default selection).
5. I pressed #2 again to accept and it was done.
All that is left is to do is some user testing to see if the monitor behaves as new.
Additional informtion: in the top of the "Factory" menu it reads: "LOVP AU Ver.0.36"
I took photos of everything and will post them on my Flickr account. To find them go to wwww.flickr.com, click on the search button, then on the next screen click on the People tab, enter my name and click search.
Thanks again for the advice.

Black Screen After Upgrading to Windows 8

Hi
I'm experiencing a black screen after upgrading a Dell N5050 B890 to Windows 8.
Tried to refresh the installation but the problem persited. re-installed the Windows 8, the machine logged in successfully but the problem arose again after reboot.
Urgent assistance needed

This problem is solved...
I guess the problem is concerned with the display module controller in the BIOS which is having a slight compatibility issue with windows 8.
This issue is solved by updating the BIOS of your Laptop/PC to the latest version. You can download the latest BIOS from the website of the Laptop company/Motherboard Company.
But for updating the BIOS, you have to start your computer/Laptop for at least one time in Normal Mode. So here are the steps to do so...
1) Boot the Laptop/PC.
2) After the boot screen (The Circle Animation & Windows 8 logo), you will be presented by the lovely & awesome blank screen.
3) Wait for 1 minute so that drivers load into the memory.
4) Press the Power button of your laptop/PC for only a moment (Just Press and release it quickly. Don't hold. We don't want to shut down).
5) This will force the laptop/PC to go into Sleep mode.
6) When the laptop/PC goes in sleep, the laptop fan & other sounds will stop.
7) After 4-5 seconds, press the power button again & release it quickly.
8) Voilllaa!!! The laptop/PC starts & you are presented with the lock screen. Now..... Login! What are you waiting for! :P
This is not the permanent solution. It just lets you start you Laptop/PC.
After updating the BIOS, I strongly suggest that you must download the latest graphics driver for your Computer/Laptop to avoid any further issues.

Black Screen After Boot up

My T420s (2 months old) recently has been giving me a black screen after boot up (no "Thinkpad" image is displayed during boot up). System totally unresponsive -- I have to push on/off button multiple times. Subsequent boot up usually OK. Sometimes once I'm up and running, upon entering sleep mode, the machine will not wake up.
I have adjusted power management setting and and up-to-date on all drives. HELP!!!

if this is constantly occurring this would mean something is wrong with the Thinkpad's hardware, since this laptop is fairly new, you should consider getting it fixed under warranty.

[SOLVED] Black screen after GRUB

Hello everyone
I was setting up a machine with E17 and was trying various DM's since none seemed to work. After attempting to use LightDM, I get a black screen after GRUB. I was trying to read the various logs at /var/log/ but I cannot understand them properly. I tried reinstalling entrance and LightDM with no luck. I even tried editing grub's entry appending '1' or 's' and still no dice. Any help would be appreciated.

No, I can't get it to work changing DM's. I'm not sure if I pacman -Syu before changing DM's another time. Maybe it wasn't LightDM's fault afterall.

Yosemite upgrade: function keys no longer work, no keyboard lights and have to sign in twice after sleep mode. Anybody else having these problems?

Hi,
Since I did the Yosemite 'upgrade' last week I have been having problems with my MacBook Pro that never happened before. The most frustrating problems involve my keyboard which doesn't light up (checked my settings and they are correct) and the top row of function keys don't do anything so I can't adjust the volume, brightness, etc. Then if my screen goes into sleep mode, when I wake it back up I have to sign back in twice - I never had to sign in at all after sleep mode before.
I'm finding that in order to get it working properly I am having to completely shut down and start up again but when the keyboard problems are happening I can't get anything on the apple dropdown to work either (i.e. shut down, restart, etc) so I can only shut down by pressing and holding the on/off button.
I've never had problems with my Macbook before and feel like Apple have completely ruined it in one update! I've had a look through other posts on here but can't find anybody else having these problems so I would be really grateful if anyone could help me and offer me some advice on how to sort it out.
Thanks!

Black Screen After Windows 8 64-bit Upgrade (Clean Install) on TouchSmart IQ508A (IQ500 series)

Hi there,
Just installed Windows 8 and am getting a black screen after booting up like many others. I currently have disabled the graphics driver and this has solved the black screen issue but I can no longer use my web cam for Skype (although web cam works for W8 Camera App oddly).
To date I have tried the following:
Loading up the latest Nvidia drivers from the Nvidia website
Attempting to use the drivers for Windows 7 both in compatability mode and normally. I unzipped SP44488 to get this working
I know many others are having this problem so I really would like someone from HP to respond and state whether a Windows 8 display driver for the Nvidia GE Force 9300M GS is being developed.
I ran the compatability wizard prior to the clean install and it came up with no issues so I am very disappointed I am having these problems.
I've found out that HP have a customised version of the above card so that explains why the Nvidia drivers dont work so I believe HP is therefore obligated to provide a driver.
If anyone else is having similar issues please respond as this will hopefully lead to more action.
cheers
Steve

I'm in the same boat. On my IQ804, the Nvidia GE Force 9300M GS card crashes when I use NVidia's latest Windows 8 driver and Microsoft's LIVE UPDATE drivers. I have to resort to the Standard VGA driver in order for the pc not to crash into a black screen.
I read on another forum you can try installing a July 2012 version of the driver from NVidia and that should solve the problem. I tried it once. Using the July 2012 version, the screen would stay on longer, but eventually it crashes into a black screen...but definitely more usable than the latest from NVidia and Microsoft.
I too have heard that HP used a customized version of the graphics card and that's why neither HP nor NVidia's drivers work.
I also tried installing the Nvidia GE Force 9300M GS drivers for Windows 7 that I downloaded from the HP website. It didn't work either. It actually failed to install altogether, saying my system is incompatible.
As is, the pc works fine. But videos and games that require motion is noticably choppy.
Any help from HP??

Black screen after login while on battery with graphics switching enabled

Getting a black screen after entering my password while logging into my account while on battery with graphics switching enabled. Everything is up and running, I just can't see it.
I can log into the guest account on battery
I can log into my account while plugged into power
I can log into my account on battery if graphics switching is disabled
I believe something that is starting up in my account is causing the system to switch from integrated to discrete graphics on login, and that switch isn't working correctly on battery power.
As a work around for now, I can run with graphics switching disabled, but I'd like to solve this so I get longer battery life.
MacBook Pro Retina 15"
Mountain Lion
All updates applied

I had the same issue and managed to reslove it.
Shut down your machine.
Power it back on while holding the 'shift' key (left or right, doesn't matter)
You will see a greay progress bar go across the screen while you boot in to 'safe boot'
Once booted, login, and go to Energy Saver and turn on 'Automatic Graphics Switching'.
Reboot back in to normal mode, and you should be able to log back in and see again.
I did this without being plugged into AC power.
Hope it helps!
Cheers!
