Screen is black, no fan is running, LED lights for volume is on/off

On a random day, I opened up laptop to use and hit the power button, everything turned on but the screen slowly went white. turned back off & then back on & still did same thing. A couple months later, tried to use it again, LED lights for volume, network, and light on front of laptop are lit, but everything else is not; screen is black, no fan running. This is only when I plug an HDMI cable from one laptop to another. Laptop was plugged into charger, when it is unplugged of hdmi, it is completely useless. Is there some way I can get the files back that i had on the laptop? my brother said a while back that it is completely shot. Id really appreciate some help & if anyone knows the fees I would have to get it fixed by HP or best buy, that'd be great! ( if it is even worth fixing, let me know.)

If you want us to help, then tell us what kind of laptop we are discussing. What are you trying to do by running an hdmi cable from one laptop to another? It will do nothing so don't do it. You can check to see whether it is the motherboard or the screen by connecting an external monitor and see if it gets a picture on the external screen. You can get your data off by removing the hard drive and using an adapter to connect it to another computer.

I dropped my iphone, it cracked (it alredy had some cracks in it) and the screen is black but sometimes has a background light.. When i plug it in to charge or to the computer it vibrates every 10 seconds and itunes does not recognize it. What can I do?

I dropped my iphone 4 pretty hard, it cracked (although it already had a few cracks in it) and now the screen is black but sometimes has a background light turn on and then off. Holding the home button and off button at the same time do not work. When I plug it in to charge or to the computer it vibrates every 10 seconds and itunes does not seem to recognize it. It gets really really hot when plugged in (which I don't think is normal). icloud does not recognize it under "find my iphone" either. What could the problem be? I am wondering if dropping it dislodged something inside. if so, what did I dislodge and is it possible to fix this myself?
Thanks

Sounds like that drop was a critical one, my friend. I would make an appointment at your nearest Apple Retail Store, because you're going to need a replacement. Also as a side note: the reason that the charger is making the phone vibrate over and over is because there is a disconnect somewhere in the charge port of the phone, causing it to plug in and out over and over.

My screen wont turn on, and the screen is black. It was working fine, but then it just turned off. The only way it will work is if I close my laptop, and pinch the two screens together

You have a hardware problem and you should take it into a apple store to be looked at and fixed.

My screen is blacked out, it will pop back in for a few then fade back out

my screen is blacked out, it will pop back in for a few then fade back out; does this happen to anyone else?

Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings

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.

Please add indicator LED light for the HDD and sleep back, add some system hotkey

After Lenovo have announced the new T440 T540，we were shocked by the graphic card: GT720m (game card) and no indicator LED for HDD. At last we need a NVS graphic card to do some grophic related work or mobile business.
So we waited for the new w540, after coming to public we were shocked again there is :
- no indicator LED for HDD, sleep, wift and bluetooth,
- no hotkey to disable touchpad
- no hotkey to sleep
- no turn on/off screen hotkey
- no hot plug for cdrom or second HDD
these are miserable and somehow funny, maybe no indicator for apple is ok as most new macbooks are all SSD
rather than mechanical hard disk.
maybe no led for sleep for apple is ok as Mac OS goes to sleep very quick and they use SSD. But for thinkpads we close the lid and wait for the moon LED light to take thinkpad freely, also for the sake of hard disk rotation. Now we need to look at the power button which is impossible when the lid is closed.
no hotkey for sleep ? some friends said " Fn+4 acts as a suspend shortcut (I think it was added in BIOS 2.05)" , we hope it is ok.
no notkey to off display? no hotkey to disable touchpad? It is really unconvenient
So is there update for these minus? Hotkey may update by the BIOS and driver. Will lenovo do so? After testing well, it will be back really easy to use.
And is there any Modle B for w540 to add LED back ? Missing indicator LED for HDD is nightmare for troubleshooting. Miss sleep indicator in front of Thinkpad(A-Side) is miserable for bringing sleeping w540.
Miss wifi and bluetooth is also unconvenient..... And it is not a very hard work.
Also it is said there is no driver update for fingerprinter reader from AuthenTec, because AuthenTec is bought by Apple?
For thoso who do is really smart but also keep the good previous features,
PLEASE

Today on shutting down the W540, I get the Windows blue shut down screen with the comment:
"Operations are in progress, pleases wait. The machine will be turned off automatically after the operations are complete."
OK, so I waited 20+ minutes.... Mouse logo spinning, but no idea what i/o's are going on. Fast disk access? Slow disk access, intermittent disk access? Or is it locked? CtrlAltDel has no action. Mouse cursor does move.
So did a cold boot/restart (still not knowing what was happening in the Black Box). Must have locked up restarting, as I waited 10+ minutes with NO IDEA what was going on, a REAL "black box".
Cold booted again, and tried a Safe Mode. Worked!, and did a check disk - said not errors????. All OK now.... but WHERE IS THE HD LIGHT!!!!!!!
Now I just cheked, the Dell, ASUS, TOSHIBA, SONY workstations have them..... We need to review this carefully at the R&D level, AND NOT LISTEN TO MARKETING! T'was, my fault for deciding on the W540, I never checked that specification, and just ASSumed all the indicators lights would be there! Now I'm stuck with a $2,500 toy - never feeling secure in the work being done. I need rwo more workstartion, but it will be a nuissance to be on two types of workstations.
When I run my Stat package, it takes sometime 1+hr of analysis, I have no idea if the program is waiting, paused, or locked.... no HD activity light, no heartbeat no idea if I need to reboot, or wait. Maybe it's an act ot terrorism to waste US worker's time ???? <g>

DV5-1159se LEDs light on bootup then go off, reboot starts

After I powerup fan starts, all LEDs are lit for about 5 seconds then it all repeats, over and over. Screen stays dark. I did hard reset, made certain insides plugged in firmly. Any ideas?

No Notification LED Light for Missed Calls Since Update

I used to get a LED light notification when a call was missed. Now since the new "update" I no longer get the notification. Anyone else notice this? How do I get the LED notification light back?

This happened to mine right after updating, and was easily fixed by clearing the Cache of my texting and email apps. None of my LED indicators were working, but it's a simple fix. Just go into Settings -- Applications -- Manage Applications -- Select your texting and email apps, and select Clear Cache. That will also fix your call/voicemail notifications. No need to go buy an app.

IMac G5 screen goes black and fan gets loud...?

This has never happened before...
Randomly tonight while on my iMac the screen shut off. The computer was still running, but my screen was completely black like it was off, and the fan got really loud. I turned it off then back on each time it happened (3 times), and it would turn back on like nothings wrong but then after probably 30min. of using it... it would happen again.
Any idea what it could be? This had never happened before, and I couldn't find a whole lot on google.

"my problem might have to do with overheat and/or I might need to "vacuum" part of my mac. No idea how to do this and I'd like instructions on how."
Since the iSight cannot be taken apart unless you take it to an AASP, the only thing you can do is use a vacuum hose specifically one w/a brush on the end so as not to scuff up the plastic. Just run the hose over all the computer vents.
Make sure your computer is OFF when doing the above.
Also, when troubleshooting, disconnect all devices from your computer except for the keyboard & mouse.
Move the computer to a less dusty place and/or move it where the computer can get plenty of ventilation.
You mentioned that you read rockstar's post. Therefore, please advise all the troubleshooting suggestions that you have already tried. This will eliminate all the +"been there, done that"+ scenarios. Thank you.

My screen has black as the backlight instead of light. I did the update shortly before this occurred.

MY screen has a black backdrop instead of light. Wonder where to change the setting. Not in the settings that I can find.

Hi Lisa,
Go into Settings>General>Accessibility and see if "White on Black" is turned on. If it is, turn it off. Also, check the "Triple-click the Home Button" setting to make sure that the "Toggle White and Black" is not turned on there.
Hope this helps!
Cheers,

If you have a VGA display and a correct display adapter, you should be able to see the computer's desktop and access it there.
The http://ifixit.com site has various repair guides and as a reference, you could look into the proper one for your model and build version of Mac to see what they say. Some users of their site contributed comments in a few of them.
http://www.ifixit.com/Device/Mac_Laptop
Details are important, since the model number may represent many years of changes, and not tell exactly what one you have. And the serial number in your computer can be used to identify-by-serial number, information on the model you have, its configuration as shipped, year, etc.
http://www.powerbookmedic.com/identify-mac-serial.php
Or try & find it at http://everymac.com database.
There are circuits, and cables that flex when the display lid is closed, plus another one that sits by the logic board that support display function, so one of these probably has failed. It would require an authorized repair or someone very handy and experienced in this design of portable computer repair. I doubt a casual user would be able to replace the correct parts; then without causing another kind of issue if they messed up some other parts that currently are not contributing to the symptom you noted.
Troubleshooting is something an expert can do. But you can use the computer with a second display so long as you have an adapter that will work with the kind and type of ports and plugs that are there. Other adapters exist that may not work, but can look very much like those what do.
Good luck & happy computing!

Upgrading to 10.9.4 causes slower startup time & system gets hot and causes fan to run during startup for no reason! Never did this before.

Macbook pro 7,1, osx 10.9.4.. just upgraded from 10.9.3. 10.9.2 was installed fresh in January.
Before that I had snow leopard. Never before has the fan turned on during startup in the 3.5 years I've owned this machine. That means the laptop gets hot? Why would it get hot at startup? And it takes 5-10 seconds longer to boot now too.

Same problem here. I just upgraded from 10.9.3 to 10.9.4 and the fan hasn't stopped since. Before seeing this post I was starting to get VERY worried. Now I'm thinkin..... Apple - ya gotta fix something here!!
