Laptop is moved....screen goes black

I upgraded to snow leopard a couple of months ago and a couple of weeks ago I started having this problem: sometimes (and it seems to be happening more and more) when I move my laptop ( the screen goes black (sounds like it goes into sleep mode) but I can't get it back and will have to shut it down and restart. This happens when its running on the battery or plugged in. Any ideas?

Try a SMC reset.

Portege M400 freezes, screen goes black and fan speed increase when moved

Can someone please help me?
I recently received the Portege M400 from a friend 4 days ago and reformatted to Windows XP Tablet edition.
All was going well until I wanted to move the laptop to my coffee table, but as soon as I move the laptop it freezes, the screen goes black and the fan speed increases dramatically!,
So far I have had no success in fixing this problem and I much appreciated is some one could help me!

Hi there,
I have the same laptop. Bought it from a friend also! That was a year ago. It was working perfectly till 6 months ago when I had it going 100% like yours. Screen freezes, fan speeds up and hangs up once it is moved. Recently, even if it doesnt move it hangs up also. I have tried many things like reinstalling drivers and Windows.....etc.
I dont think it is Windows problem or drivers problem, because if you run BIOS and try to move the laptop, it also hangs up!!
Tried updating the BIOS, also no benefit. I ended up opening the laptop and having a look to the motherboard (thinking that I could see something that I could fix!! But again, did not get any results.
I tried also disconnecting peripherals one by one to see whether I could spot the problem, I disconnected the battery, the hard disk, the optical drive, the wirelss modem (from inside), memory, and even the bluetooth, but could not spot the culprit.
I believe now that the problem is basically the motherboard (sort of wear and tear insulation problem) and it is beyond my humble expertise.
I am sure if I would contact TOSHIBA, they would not be of much benefit as I am a second hand user. And if I try to buy from them a main board, they will charge me hell of money.
I hope that this is helpful for you to avoid you wasting your time like me.
Please if you would come into any progress, let me know. Likewise, I would be happy to update you.

My laptop screen goes black when i plug in an Hdmi cord

Initially I had both my tv and computer off. I connected the dvi to the tv and the hdmi to the laptop and turned them both on. I had no issue using my laptop as i tried to sync the computer to the TV. However i must have accidentally hit something in the graphics options as my laptop screen went black. I unplugged the hdmi cord from my laptop and the screen came back up. But now for some reason everytime i plug in the hdmi cord to the laptop the screen goes black. When i take it out it the screen comes back up. Did i change something that is causing this to happen? Any help would be greatly appreciated. Thanks

I have pretty much the same exact problem and setup as DaveA1. I have a Toshiba Satellite Laptop C55T-A5123 which I just purchased a few months ago and when I connect my laptop to my SONY TV via the HDMI cable the screen on my laptop goes black and the TV says no signal. It was working just fine up until about a week ago when I was watching a movie through my VLC player and then the screen flickered a couple times then video went completely out and I've never been able to get it to come back even once.
Here's the specs on my laptop:
http://www.newegg.com/Product/Product.aspx?Item=N82E16834114907
So far I have tried on two different TVs, swapped HDMI cables which work on my other HDMI devices, system restore and attempted to update various different drivers. I am curious to find out if Dave was able to find a solution to his problem.

Laptop screen goes black when HDMI connected to TV

I have a Thinkpad Edge 431. I've set it up in Control Panel to duplicate both the laptop and the external monitor when connected by HDMI. It works fine.
When I connect it to my TV, the laptop screen black. The TV displays "No Signal" until the HDMI connection is made. When the laptop screen goes black, so does the TV screen. No sound or picture.
This was working fine until recently, and I can't figure out if I somehow changed settings to make this happen. It's clear that to me that the HDMI port on the laptop works, as does the cable.
The TV port works (I've switched the connection on the cable box to each HDMI port on the TV, to make sure they work).
I can't change anything in Control Panel when I connect the HDMI, because the screen is black.
I've updated the Lenovo system.
The other relevant piece of info: the Intel Graphics Card control panel says that Monitor/TV Settings are not supported (although until recently, I could easily display the computer on the TV).
Can anyone help with this? Thanks!

No video and audio signals to the tv connected

[SOLVED] Connecting extra Monitor, laptop screen goes black.

Whenever i connect a additional monitor through HDMI (my only output), the laptop screen goes black. If i do FN + external_monitor switch, then the laptop screen turns on but the external monitor turns off.
If you move the mouse you can feel that the desktop has been extended as i wanted, it is just that one of the screens keeps going black. The gnome display settings show both screens as active, the menu is so minimalistic that there is not much to do.

As a side note, the custom kernel is almost identical to the original archlinux one, just that USB 3.0 module is disabled.

Any ideas?

The problem is now fixed,
For some weird reason, this time the gnome settings did work. Must have been some sort of rare bug that now i cannot reproduce.

Narcoleptic laptop - screen goes black while working

Hi ho,
About a week ago my mac started acting strange. I'll be working and the screen will just go black. (it just did it again! Sometimes if I'm listening to music on my mac, the music will stop, so it's not just the screen going black, it's like the computer goes to sleep out of the blue.
I was trying out bittorent for the first time and I'm wondering it it's related to that, if there is something I don't know coming on to my computer from the internet, please advise. I took bittorent off and it'll still appear. A window from Opera will open, so I took Opera off my computer in case there is something downloading. I never use Opera, so I don't know why it keeps coming up.
When it goes black, sometimes if I click the power button, I'll hear the disk repower up and the screen will go on, but it isn't all the time. Once I get it started again, it may be a few minutes and it'ss do it again without warning, or it could be 10 seconds. There's no rhyme or reason.
Another thing I notice is that the laptop will get hot, and I'm wondering if it's an emergency mechanism if the computer is getting too hot.
Please help, of course, I'm dead without being able to use my computer! And this is totally messing with my productivity!

Hi, madamep. A properly-functioning Powerbook should put itself to sleep (not shut down entirely) before it gets hot enough to do real damage to itself. That may be what's happening with yours, as you say it seems to be getting pretty hot.
I suggest opening Activity Monitor and seeing whether something is using a lot of CPU cycles a lot of the time, thus generating extra heat. If you find that something is, and it's something you recognize and can comfortably turn off, do so. Then see whether the unexpected-sleep problem diminishes or disappears. If there's nothing drawing heavily on your processor, are you using the Powerbook on a soft surface (bed, sofa, lap, etc.) that's inhibiting airflow around the PB's shell and through its cooling vents? If so, don't: it needs unobstructed airflow all around it, including underneath — that's why it has little rubber feet, to keep it elevated slightly above your table- or desktop. Always use it on a hard, flat surface, and if the feet have come off it, replace them with something that will provide airspace under the PB at all times. Also check to make sure the vents haven't become clogged with dust or fuzz: use canned compressed air or a household vacuum cleaner (not the brush attachment — that can generate a lot of static electricity that's dangerous to electronics) to clean the vents from the outside.

Re: Satellite M100-221: screen goes black moving the display

Hi,
I have a problem with the lcd display on toshiba satellite M100-221.
When I move the display the screen goes black.
The display works properly only when the angle is close to 90 degrees.

Hi buddy,
Im not a technician but I agree with the user above. For me it sounds like a hardware problem and you should go to an authorized service provider. The technicians can check your notebook and exchange faulty notebook parts.
You can search on the Toshiba website for nearest ASP. ;)

My screen goes black

This happens very rarelly but when it does its always at a bad time. I am working on some things and all of the sudden my screen goes black and there's nothing I can do. I have to hold down the power button until it shuts down then I start it up again. WHATS GOING ON??!!

Hi Michael and all,
I encountered the same phenomenon that Michael mentioned in the last post. First, my computer screen would go black for just a few seconds. For me this would always happen when my screensaver pictures were just about to turn off and put the computer to sleep. When I'd try to bring the computer screen back up by moving the mouse or tapping the space bar, it was like a struggle for the computer to come back to life, and I'd have a black screen for a few seconds, hearing the drive revving up, but no picture and no glowing sleep light (by the way, I have a flat screen G5).
Then, last night, instead of just a few seconds, the computer went motionless for hours. Again, this happened just as I was trying to bring the computer screen back up after it was in the screensaver mode and moving on to the sleep mode. The computer would not respond to any keyboard command, but the mouse was still awake and glowing red. The power button on the back of my G5 was non-responsive. I read all of the posts here on the Apple forum (by using my laptop), panicked, and thought, "forget this". Said a little prayer, unplugged the Mac from the wall, waited a minute, and then plugged it back in. Miraculously, I pressed the power button and the computer started right up normally, with the happy Mac sound and all. I didn't even lose any data (luckily, I back up regularly to discs).
The first thing I decided to do, after reading all of the posts on this forum on what seems to be a big problem, was to go to my system preferences and opt to never have my computer go to sleep again. I'm only leting the screensaver start up after an hour away from my computer (which is very unlikely--I usually shut it down after 30 minutes use). My thought is that this is some bug that occurs when the computer is transitioning to sleep mode, and again, I came up with this theory by reading all the posts on this subject.
Michael, I am responding particularly to your post, because it seems to reflect most exactly what happened to my Mac. Today, all is well, and I hope it stays that way.
In sum, my suggestion would be: don't let your computer even flirt with the sleep mode until Apple has some concrete fixes for this problem that don't require $$$ (by the way, I read one post from someone who paid almost $800 to have it fixed, and I can't remember if it was ever really fixed).
Hope this helps,
Anne
P.S.--Now if someone can answer my much-less-critical question about signatures that I posted, I'd appreciate it!

My screen goes black all the time!

Ever since I installed Leopard, my screen will go black if I don't type anything for just a few minutes. (I can barely see what's on the screen ... BARELY)
My laptop is plugged in and receiving power so that's the reason.
I have checked my power settings at that is not the issue.
I have checked the timing on my screen saver and that is not the issue. (my screen saver doesn't start when this occurs)
Does any have any suggestions?

Sorry you're having this problem.
A few years ago we had a similar issue on one of our machines, it was an early MacBook. Ended up being a cracked circuit connection on the motherboard. Changes in temperature caused the crack to expand and contract resulting in a shut-down followed by an automatic reboot. Sometimes over-and-over. I understood from AppleCare at the time that those symptoms could have also been any number of things including a intermittent issue with a powersupply.
If you take it back to the Apple Store at some point, I would ask them to have it run some CPU intensive tasks that closely resemble what you are doing when the screen goes black. It took us several try's to find the problem. Calling AppleCare each time to discuss it and troubleshoot before making the trips to the Apple Store really moved things along. In fact, it wasn't until the Apple Store had cracked the case from the inside that things kicked into a higher gear and AppleCare phone support sent out a pre-paid FedX package to send it to a refurbishing facility. Never a problem since and I know the people who have the machine today.
PS Can identify with the trip to the Apple Store, our closest one is in Knoxville, 2hrs from us.

Screen goes black randomly

Hi everyone.
I have a very strange issue on 2 different PCs.
From time to time the screen goes completly black, and I have to wait about 2-3 seconds for it to restore the picture.
Both have NVIDIA video card, one PC has GF8900GT the second GF7200.
Both PCs running GNOME
In both PCs the screen is connected via DVI port.
One PC has Arch installed for about 4 months the second has a 3 days old installation.
I also have a laptop with Arch (about 4 months) but I didn't expirience any issues there.
I'm not sure what the problem is, but it really annoys me.
I'll be very gratefull if someone points me in the right direction.
Thanks in advance.

Satellite L405D-11V - Freezes and screen goes black when watching video

Ok, so I have the Toshiba Satellite L405D-11V, I have had a fault, basically, the computer would freeze at any time and the screen would go black, with the fan and lights still going, this could be on start-up, or a few hours into using the laptop, so I decided to ring up Toshiba's tech support and they arranged for my laptop to be collected and sent off for repairs.
I was able to track the repairs online through the tracking service, and was able to see what they were doing to my laptop, it said that they ordered a part, it was in progress and the repairs were finished.
However, I got the laptop back today, I turn it on, everything is fine, I start using the laptop everything is fine, then I decide to watch a video on youtube, and it freezes again, so, I power off holding down the power button, hoping it was just a one off, I turn it back on, and load up the video again, it freezes and the screen goes black again, after working out that when ever I watch a video or play a game, it causes the computer to crash and freeze like before the repairs. So there is still a fault, but im not sure what to do
Its still under warranty, I purchased the laptop from Comet, but I dont really want to send the laptop off for repairs again and to find it will come back with the same fault, is it worth sending it off again, perhaps seeing if comet will replace the laptop as its still under a year of buying the laptop, or is it just gonna be worth saving all the hassle and buying a new laptop? If this fault has happened to anyone else, I could sure use some help, and if someone could shed a little light as to what might be wrong?
Thanks

Hi buddy,
Did you change something on configuration after you got your notebook back from repair? Did you update a driver or something else?
What operating system you are using on your Satellite L405D?
To be honest its really hard to say why it happens because the technicians test everything to check if your notebook runs properly.
In my opinion you should try updating the display driver. Maybe its causing the issue
If not I would recommend installing Windows from Toshiba recovery disk to restore factory settings. These settings are pretested by Toshiba and should work.
If you still have the problem you must contact the technicians again. I mean you could track the repair online and according your posting everything worked well during repair so in my opinion it shouldnt be a problem to contact the guys exactly.
Explain your problem very detailed. I think everything can be clarified then. :)

PB screen goes black when TV is plugged in

I occasionally plug my PB G4 12" into the TV using the Video Adapter. This used to work fine - the desktop would span both TV and PB screen, just as it does when I have my external monitor plugged in.
But when I upgraded to Leopard this stopped working - when I plug the TV in, the PB screen goes black 90% of the time. And when I unplug the TV the PB screen stays black - I always have to shut the laptop down while the TV is plugged in and start it up once the TV is unplugged. But the PB still works fine when I plug an external monitor in.
Any ideas how to make this work again? Thanks.

Issue with Macbook Pro (early 2011) screen going black.

I installed an SSD with Mt Lion. Periodically the screen goes black like it's going to sleep. It hasn't done this in the past just noticed it the last few weeks.
The SSD is a Crucial with 8GB of Crucial memory. I've got all the software fixes up to date. Has anyone else seen this. I've read a few postings, one mentioned issues with Mt. Lion and another with a logic board in the laptop.

Well, seem like there's already ton of thread related to this issue ...
