MacBook :: Black Screen But Sleep Indicator Is Coming On And Off
Feb 18, 2012
I've got pretty old MB that was bought back in 2007, and it's been working ok up until today. All of a sudden I can not boot it, the screen stays black. Whenever I turn it on the screen flashs for ~100ms and then remains black, at the same time the sleep mode light is on and off not gredually fading in and out like when it is in sleep mode but sharply. Safe boot didn't help, PRAM reset didn't help, booting into the firmware (CMD-OPT-O-F) didn't work as the screen stays black. . I can hear hard drive working but other then that I see no signs of life (even caps lock and num lock keys don't get highlighted when I press them)
Today, my mac freaked out on me twice. I was watching something via Quicktime and all of the sudden the screen went black and green and started going crazy like it was twitching or something. And I got this loud noise coming out of my speakers. My MacBook is about 3-4 years old.
since last night (monday) i have opened my mac book pro up for sleeping because i never shut my computer off....well last night i opened my computer up, typed in my password and then all of a sudden my screen went black....i called apple support and got it fixed but then again it happened again to me this morning? why is this?
My macbook pro is only a month old, and I've done nothing to it besides write documents and use facebook. Every time I close the lid so the computer can "sleep" it does, but when I open the lid back up, it refuses to wake up. My friend has the same computer and automatically her screen lights up when she opens the lid from sleep. My screen will stay black up to 10 minutes sometimes. Why is this happening? Should I bring it in to Apple? Also, when I shut my computer down, starting it up is another hassel in itself. The screen goes white like it's suppose to, but only for a split second. The apple in the center never shows up, and the screen just goes black. It's very aggravating and I feel like I'm the one with the only messed up mac.
when my macbook pro go to sleep mode and after i try to started it - I got black screen and have a loading cursor mode, If I close my macbook and after 3 minutes open - all working fine!
Info: MacBook Pro with Retina display, OS X Mavericks (10.9.4)
I just purchased a brand new macbook air this past week. I noticed within the first day of using that if my machine went into sleep mode, and I hit a key to take it out of sleep mode, it would go to a black screen with my cursor for about 30 seconds.
It does not do it every time but enough that it is annoying. I am coming from a mid 2011 mac air that did not have any issues. (only replaced for all day battery)
Do you think this a hardware or software issue? If i swap this mac out do you think I will just encounter the same thing?
I have read numerous posts regarding waking from sleep issues but they all seem to be affecting MacBooks purchased between 2012 and 2013.
My MacBook Pro 15 inch mid 2010 model i7 processor is having problems when I close the lid and the computer goes to sleep. Heres how my problem is occouring. I close my macbook pro lid. After waiting about 10 min (my macbook sleep time) I lift the lid. Once I do this i see the screen.... for about 2 seconds and it suddenly goes black. I fix it by turning my brightness down 1 bar then turning it back up 1 bar. I dont remeber this happening on snow leopard it seems to be a lion issue and a lot of other users are having it.

When I open MacBook Pro (in sleep mode) I see rainbow on black screen. I have to keep the power button. I have this problem only when I open (after closing) my MBP. It started after an upgrade HHD to SSD (OCZ Agility 4). SMC reset did not help. I have MBP 13 late 2011 i5 2,4. Mac OS X 10.7.4.
my macbook air 13 display only black screen and pointer when wake up from sleep. its not frequently happen. to become normal it take 10-15 sec, is it hardware problem or software problem?
I recently had to reset the SMC on my Macbook Core Duo in an attempt to rectify a separate issue and now I don't know if the sleep indicator LED is behaving abnormally, because I don't seem to remember for sure how it was before the SMC reset.Can anyone tell me if the Macbook's sleep indicator LED on the bottom right hand corner should be lit when the machine is switched on? I can almost swear it wasn't before, but now the LED is constantly lit up.
I have a 2 month old 13" MBP which I absolutely love. The only hitch is that there is an oddity when connected to my Dell 2008wfp display. It only happens when I wake the MBP from sleep. A number of things happen sometimes. Usuaully, when I wake the MBP from sleep, i get a black screen on both displays and all I can see and control is the cursor. Sometimes the main display will be black, but the MBP display will show the desktop wallpaper, but again, I can only see and control the mouse cursor. It should also be worth mentioning that the keyboard is rendered non-functional as well.
Sometimes, OS X will appear on both displays, with mouse cursor active, keyboard inactive, but I am unable to click anything or interact with anything OS X.
Anyway, I'm at the point where I need to mention this because it happens quite frequently and its getting rather annoying. The only way I can get out of this hang, is to cold reboot the machine. It happens everyday and at least 50% of the time I wake the MBP from sleep. When not connected to the display, I never get this occurrence. Also, this display worked perfectly when I used to own the classic 15" MBP, so its hard for me to pinpoint what exactly is the anomaly that is happening.
Anyone else experiencing this same issue? I am using a mini display port to DVI adapter to the Dell display.
I noticed a couple of days ago that my sleep indicator has stopped working. When I shut the lid the computer goes to sleep.... when i open it back up after 30 seconds or a minute msn tries to reconnect and i heard the cd make that little noise that it does... anyone know of anything i could try to make it work again?
This is my first mac, it's a Macbook Aluminum Unibody 13" 2.0GHz... this is the only problem I've encountered.... I know it's pretty minor, but I like things to work as they're supposed to, especially when they're this new.
I've noticed that when my rMBP (late 2013, Mavericks) turns off the display automatically while on battery (as configured via Energy Saver) and I try to wake it immediately, I get a black screen with the cursor, rather than my password/unlock screen. It remains a black screen, with the cursor moveable, for 5-10 seconds or so, and then the password/unlock screen will appear as usual.
This does not happen if:I don't try to wake the display/computer immediately after automatic display sleep (e.g., I wait 5-10 seconds and it's fine)I turn off the display using a hot corner and immediately wake the displayI put the computer to sleep by closing the lid and immediately wake it by opening the lidI select Sleep from the System/Apple menu and immediately wake it by pressing a key or clicking on the trackpad
Why automatic display sleep is causing this temporary black screen? I currently get around it by setting the time for automatic display sleep while on battery to 10 minutes instead of the default 3 minutes to minimize the chances of needing to immediately wake the screen. I'd like to keep it at 3 minutes if possible to maximize energy savings, but the temporary black screen is really annoying if I didn't really want display sleep and consequently have to wake immediately.
due to my low skills in electronics I want to know this.The shiny logo at the back of apple laptops, and the shiny sleep indicator, are these some kind of lamp? If so, dont they ever run out of electrons? Like when you have to change your light bulbs at home. I have never heard of them stop working so I guess they work in some other way?
PROPOSITION: Turn the sleep indicator light to a power indicator light.
I just noticed, the sleep indicator light pulses when my MBP is in sleep, but is always completely off when it's in use. This is actually a little frustrating, as sometimes I leave my MBP idle with the screen off and the backlit keyboard off as well, and I can't tell if the thing is on or not since it's dead silent.
Also, I noticed that when I leave my MBP plugged in, idle overnight, the sleep indicator light is solid in the morning. It's definitely not indicating sleep, since the unit is on, so I'm not sure what it means.
Anyway, anyone else think the sleep indicator light should be solid when the computer is in use? How would you tell the difference between an MBP that is powered off, and closed and slipped into a backpack, from an MBP that is simply powered on but fails to enter sleep for some reason?
Is there a way to keep the light on forever, sort of like a power indicator? ALL my previous laptops have some sort of power LED just so you can at least tell it's on. It just doesn't make sense to me.
When I wake from a long sleep, my screen comes on but everything is black. If I move my mouse around, the tiles behind the pointer switch over to whatever app is open. When I invoke expose/spaces, the screen fixes itself and displays everything.
I've been experiencing a black screen with a frozen cursor (everything is basically frozen) after waking up from sleep in Windows Vista. The Mac side of things are fine, and its super annoying, because I have to do a hard reboot each time this happens. I tried google, but it appears that everyone that has a problem similar to this has a responsive computer or just needed a different driver for their graphics card. I've tried installing a different X1600 driver for this, but it didn't work. I'm on a MBP1,1 running Windows Vista SP2 (fully upgraded) with Bootcamp 3.1.
For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.
In the last 2 months or so, I have seen my MacMini 2011 OSX 10.7.3 crashing withing a minute of wakeup, after sleeps of more than 2-3 hours.
Sometimes the Black screen occurs almost immediately, sometimes it takes up to a minute after the desktop appears (after logging in). This did not occur until I got 10.7.3 and only within the last 2 months.

when working on my new Imac sometimes the machine put itself in sleep mode! The screen turns black and I have to enter my password. Sometimes it happens 2 times in 1 minute; other times once in 1 hour.
I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all.
I have an early 2008, 24-inch iMac. This problem started after I installed an OS X Mavericks update (and has continued). Basically, after the screen is asleep for a while, if you come back and move the mouse / tap the keyboard, the desktop never reappears. The screen stays black but the mouse cursor shows up and you can drag it around. I've seen some similar issues that said they could get the app switcher, but that never happens for me. Just mouse cursor and black screen, no matter how long you try to wait it out or tap buttons. The only solution is a cold restart, although I think in the past I was able to fix by turning off energy saver settings for putting the display to sleep. It doesn't happen every time, I'd say it happens over 50% of the time. The problem actually kicked in with one particular App Store update of Mavericks. I believe it was 10.9.3 if I recall correctly.
when i leave my macbook pro alone for a little and the screen goes a little dark to prepare for sleep, i click the mouse pad and it doesnt come out right away. it also does this sometimes when i close the laptop and open it.
Lately my 13" early 2011 Macbook Pro has been locking up when in sleep mode. All I get is a blank screen and the cursor which responds, but no buttons pushed on the keyboard resolve issue. Resolution thus far has been to hard boot the macbook...
when i have my macbook on and close it (sleep mode) and re-open it at a later time. it typically makes four noises (basically sounds like it is reading the hard drive for 1-2 seconds when you open it. lately it is making those same noises but noticeably slower. what could be causing this? is my hard drive going to go out on me soon? i have about 10 GB free on it.
So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3.
The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.
I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests.
At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower).
