Lenovo W500 Black Screen | Tried all the manuals already...
Hello,
I just joined this board though I hope to get some help here.
First of all, I know that there have been sevaral threads discussing these issues already but unfortunately non of them could help me to solve the problem.
Sometimes when I boot my W500 the screen stays black. The computer is booting up in the background but the screen is either just black with background light activated or just black as if the computer was turned off.
I have switchable graphics activated and all drivers were installed properly and according to manuals that promise to solve this issue. I tried every posible combination in the BIOS (including resetting the whole configuration of course). The BIOS is up to date. Windows 7 is installed.
To be honest, I doubt that it is an hardware issue. If the screen stays black there is at least one thing that I can do: I remove the hard disk, start the pc and hey.... the picture is back. I put the hard disk back into the pc and it works for 1-2 boot processes. Maybe this just unloads the CMOS but I doubt that this is the only reason though pressing the on/off switch sevaral times with disconnected power cable does not do the job (or at least very unfrequently).
I would like to know how this works, so that maybe I can come up with a proper solution. I need my W500 for daily work and always removing the hard disk is totally annoying.
Unfortunately the Lenovo Support on the phone was not very helpful. They said it was a Windows 7 issue and that I should install Windows XP for my notebook to work properly. Weird though they are offering drivers for Windows 7 ;-)
I think I do not have to explain why Windows XP would be a bad choice anyway, today (security,compatibility...).
I hope you guys can help me! Thank you for your time!
I also have a W500 and am using it now. Unfortunately I am running Linux and do not experience this problem.
Can you connect an external monitor when the screen is black? This might let you see something. Try to learn how to log in to the system using only the keyboard (write down steps with arrows and/or tabs) and see if you can log in while the screen is black. Windows may reset the graphics after login and that might at least help you narrow down your problem or give additional information.
I am using the integrated graphics option in the BIOS. You mentioned trying all the BIOS options, but perhaps changing them is causing a n+1 problem. It will be fine on that boot, but the next one causes a problem. Can you verify this blank screen happens when you have integrated graphics set? If so then set the graphics option to only discrete and try a few boots. If you can use either one that would be important information and help narrow down the problem.
My W500 is awesome, and I have been very happy with it. I hope you can figure out this problem and fix your problem.

my apple tv 1st generation appears to have locked up. it constantly now displays only a black screen.No function reset etc from remote use.The led status is constantly blinking orange. I have tried all the manual tips etc but still blank. Any ideas anyone?
Gary.Same/similar thing just happened to me....two days ago or so. Ran fine for months since going from wifi (major problems) to ethernet now.
I hadn't been on atv 1 for a few days and had it powered down. Turned it on and it ran thru the startup video/sequence then did the ole sit on a black screen where you can hear the remote responses (say, if i hit left on the remote - the 'option not available' doink noise is made instead of the usual sound you'd get if you were moving to the left on the menu.....not sure if that description makes sense?
The 'exit' or moving out of a menu 'noise' does sound, as does the enter/moving into a menu noise.
This has happened in the past, but more when i had it set up via wi fi.
Thing is this time i left it sit on the black screen while reading the paper, and after about 5 minutes, the menu screen finally showed up. Everything was really sluggish to start - but it was there. But, then, i reset it to see if the sluggishness would go away, and back to the black screen after the startup video.....and then 5 minutes later, it came up.
Not sure what is going on...but did have the blinking orange light for a while during the issue.
Don't think its an age thing as it did this even when i first purchased it....
Once into a video or music it runs fine (though i did notice that every once in a while with the music playing from my itunes, it would have a second of silence mid song like it paused for a second, and then would resume as if nothing happened.....
Any ideas whats shaking with this? Does this sound similar to your issue or am i in a different ball park. -
Hello, my iphone 5s fell, thereafter i tried taking a picture, the camera app just shows a black screen and hangs, the front camera works on other apps (such as facetime and skype) but the rear camera is not working, all other apps work perfectly well, how do i resolve this
Double tap Home button and delete Camera app from multitask-list.
Do a
Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data

Hi, My wife has developed a problem overnight after charging her phone. The Problem is a black screen. I have tried all the recommendation from the support article, however the iPhone 4 screen still remains black
Take the iPhone to an Apple store genius bar for testing, and if it is defective and under warranty they will replace. Since you say iPhone 4, was this a used or refurbished iPhone?

My phone died last night and when I plugged it in it wouldn't turn on.I tried restarting it but it has yet to turn on since last night,It was just a black screen,i try the on/off and home buttons together but its not working,What should I do?
How long have you had your phone? Because if you've had it a long time, the battery in the phone might of died on you. Or have you dropped it in water, snow, from high up? All those things could of disconnected something internally in your phone, or permentaly damaged the internal hard drive its self, or the sims card.

I used utilities to source my 10.6 snow leopard install disc to my main hardrive, and now when I turn on my computer the apple with the spinning wheel stays on the screen and stuck like that. How do I fix it Help please. I already tried all the commands such as Command R, Holding down the Option key, C and holding down shift at the start up but nothing happens.
initialy All I was trying to do was downgrade 10.7 to 10.6 .You have to consider the possibility the hard drive may be dying. If your data isn't backed up, try one of the tools below:
https://discussions.apple.com/docs/DOC-1689
Once you are sure your data is backed up, we can examine other possibilities. In the meantime call AppleCare for your original installation DVDs. You may need them. -

i am unable to manually add artwork via itunes 12 on windows 7. I've tried all the suggestions to no avail. Has anyone succeeded on the same platform as me?
The new iTunes 12 Get Info dialog lacks right-click context menus (at least for now) but it still accepts most standard keyboard shortcuts and drag & drop actions.
Delete Artwork
On the artwork tab of Get Into, tap the image in question, use Backspace or Ctrl+X. Delete doesn't work.
Or, tap the image at the top left of Get Info, this time use Backspace or Delete, it is Ctrl+X that doesn't work.
Add Artwork
Select artwork, press Ctrl+C to copy, tap the centre of the Artwork tab, press Ctrl+V to paste.
Or, select artwork, press Ctrl+C to copy, tap the small image area at the top left, press Ctrl+V to paste.
Or, you can drag & drop to, or sometimes from, the same locations.
You can also copy artwork from the Get Info dialog to Windows Explorer with the keyboard shortcuts.
If the source image is on a web page right-click and use Copy Image rather than copy. (With Chrome I get a one pixel wraparound so tend to go for a temporary local copy anyway - not sure whose bug this is, but it isn't new.)
If you have multiple images embedded drag the one you want to be the primary artwork to the leftmost position.
Replace/Remove All Artwork
The top left image box can be used to add or delete art from multiple tracks. In either case all existing artwork in all tracks is replaced/removed.
Old Style Get Info Dialog
Select some items, right-click, hold down shift, then click Get Info from the context menu. (Use alt/option on a Mac)
If you still cannot add artwork via any of these methods then I would suspect a permissions problem. See Repair security permissions for iTunes for Windows.

I turned it off manual then restarted it only to get the beach ball of doom. I tried all the different reboots suggested in the manual without success. I'm not tech savvy so would appreciate very clear instructions if you have a suggestion that doesn't show up in Apple's as to how to get rid of the beach ball. Many thanks. Jude
Jude,
You can do a couple of things. The first thing I'd try is restarting in Safe Mode. To do that when you hear the startup tone hold down the Shift Key until you see a progress bar appear. Let it fully boot, while you're in Safe Mode open Disk Utility(Applications - Utilities - Disk Utility) and Repair Disk Permissions. While you're in Disk Utility also run Repair Disk. After completing the 2 DU actions then restart normally to test the machine. -
new airport: can't get my macbook or my imac to join my wireless automatically, my other stuff still joins without problems but i have to join manually with the book and the imac ?? I've tried all the settings and every thing else I can think of.....
Running on Lion, never had a problem before until the old airport died and I replaced it.try connecting the device in _*recovery mode*_, then restore from your backup.
also, make sure [_*Apple Mobile Device Service*_|http://support.apple.com/kb/TS1567] is installed and started.

T42P. Does not boot/startup. Black screen. All indicators except the battery and power are off.
Hi all,
I am new to the forum and so very desperate for help!
I have a T42P (2373-C61) machine. All of the sudden today, it blue-screened. I turned it off, then tried to turn it back on.
Now, it is not coming up at all. I can not even get to the BIOS or see anything in the screen!
All the lights/indicators are off except these two: the battery/power and the little z (the on indicator).
The NumLk and Caps Lock indicators flash every 15 seconds or so.
The hard drive, bluetooth, and wireless lights are off completely.
Tried getting to the BIOS by unplugging the battery and using the AC only but nothing happens when I press F1 or the IBM button.
Also, tried a suggestion from other users that requires unplugging Battery/AC, pressing Power button 10 times, then the 11th time for 30 sec. Still nothing happens.
No HW/SW was added to the machine recently...
Any suggestions is appreciated..It can also be the LCD itself...
BTW, if the graphic card has failed that equals motherboard replacement since it's soldered to the planar...
Let's hope not...
Good luck and keep us posted.
Cheers,
George
