• HP Envy laptop monitor does not light

  Just bought this HP Envy with Windows 8 just over a month ago.

  Today, after the installation of an HP recommended that Windows Update the monitor does not light.  The power led is on the internet led is activated and the CAP turns on if you press.  Still no monitor.

  Bought it at best buy and it's a drive of 1 1/2 at this store if I have to take it to Geek Squad

  If you have windows 8.1 on it then it looks like the update of kb2903939 killed. I fight with this problem since Christmas.

  Power cycle the cell several times without leaving start completely. It should bring up a screen of recovery. If you can find the path to start safe mode, you can uninstall kb2903939 and then restart. That fixed my problem.

  Otherwise, it should be a call to HP or Microsoft support.

  Hi Uther 9,.

  If the monitor does not remain during the self test, it is defective.

  * Turn off the monitor
  * Remove all cables from the computer monitor
  * Turn on the monitor
  * The floating red/green/blue/white dialog box should appear on-screen on a black background and stay on

  However, it seems that you already have, is most likely a hardware problem:

  Reliability Monitor uses data provided by the RACAgent scheduled task. Reliability Monitor will begin showing an indication of stability, and event information specific 24 hours after installation of the system.
  The RACAgent scheduled task runs by default once the operating system is installed. If it is disabled, it must be enabled manually in the software component for Microsoft Management Console (MMC) snap-in Task Scheduler.
  Membership in the local Administrators group or equivalent is the minimum required to complete this procedure.
  To enable the RACAgent scheduled task
  1. Click Start, click in the search box, type taskschd.msc, and then press ENTER.
  2. in the navigation pane, expand Task Scheduler Library, expand Microsoft, expand Windows, and click RAC.
  3 right-click RAC, click view, and click Show hidden tasks.
  4. click on RACAgent in the results pane.
  noteNote
  The RACAgent task name is maybe not completely visible. If you don't find it, expand the name column in the results pane.
  5. in the Action menu, click Activate.

  If the steps above does not
  2 reset the reliability monitor:

  3. open the Folder Options and select (dot) the hidden files and folders option, and click OK.
  4. open Windows Explorer and navigate to C:\ProgramData\Microsoft\RAC.
  5. to save the history of reliability data-
  WARNING: This is an optional step, you will not be able to restore these data if you do not back up this data and it will be gone for good. If you want to ignore this, go to step 6 instead.

• Firefox has only display problems in the upper left region of only my Dell U3011 monitor; the monitor does not have these problems with any other application

  Some parts of the Firefox window are translucent, allowing the image of the desktop to show through. These regions are anything but great internet site central image which behaves normally. Unless the desktop is completely black this problem makes reading the tabs, address bar and the bookmark are difficult if not impossible. I encounter this problem only on my new Dell U3011 monitor. Firefox is the only application that has this issue on the Dell monitor. The monitor built into the laptop that animates the Dell monitor does not exhibit this problem. The laptop is a Lenovo W540 running Windows 7 64-bit. Thank you very much for your help. Steve Schupbach

• HP monitor does not display "DVi signal.

  My HP LP2275w monitor does not display "DVI signal" when connected with a DVI cable (supplied), but when it is connected via a VGA cable and adapter DVI/VGA (both supplied) it works but no BIOS screen. It begins immediately with the logo of the VICTORY.

  I just bought new HP Pavilion 500-158eg, Intel Core i5-4440, with AMD Radeon HD8570, 2GB processor, running on WIN7 Pro 64 b. VGA and another port of the motherboard are initially blocked so I can connect the monitor only via the output HDMI or DVI on the graphics card.

  I should note that on my old machine without a name with the graphic upgrade ATI Radeon, there is no problem and I used the same cable. There was an electric shock that causes the collapse of the motherboard so I can't even re - check on the old machine. I can't verify if there is a problem with the DVI cable because all laptops in our housing have only the VGA output...

  All solutions?

• Arm, wrist and the screen does not light.

  I just wanted to give a few comments. When I walk, carry heavy bags and I want to watch the time I lift my arm to look at my Apple Watch and the screen does not light. Maybe its because the movement of the arm is subtle, since I am carrying heavy bags. I was wondering if that could be repaired since both times I tried it, annoyed me. Walk in a street busy NYC with my groceries, I would like to know something, briefly, on my watch as I walk with the duty to stop or to disembark the bags.

• Screen does not light after the start, but after standby on Satellite M100

  Hello
  I have some experience with computers and laptops, but this problem exhausted all of my knowledge.
  My girlfriend has a Toshiba Satellite M100, PSMA1E. He currently works on Windows XP, SP3.
  The laptop has always had problems closing/stand bye. He would stand bye and the screen would not. She would usually be manually turn off (holding the power button) and restart.

  Same thing happened last week, but with me. I turned off the power button but when I turned it on the screen was completely black. After a few attempts, I realized that everything worked; I could hear the usual audio files and XP Boot, but there was no way I could get the job of the screen.

  The strangest thing is that the CMOS/BIOS, one with the Toshiba logo settings screen, also does not appear. If it's an OS problem, I thought that I would be able to access the BIOS at least, but it does not work. FN + F5 does not work.

  Then, strange yet something happened. I was turning it on and off with keyboard shortcuts and I realized that if I put on stand bye using shortcuts and then go back on the screen turns on perfectly well (there is a cause of adjustment resolution icons are irrelevant, but it works perfectly fine).

  From that on I tried everything I know. Update the BIOS, all Windows XP updates, all Toshiba QuickFix, cleaning the registry with different tools, uninstall and reinstall the video driver (ATI Radeon X 1400) utility, shortcuts keyboard, power saver, tools hardware Toshiba, looking to start up programs, services, everything I could possibly think off.

  What intrigues me is that the Toshiba start screen will not be displayed. I can't access the BIOS, but I tried to restore the standard values of the BIOS with Toshiba hardware tools. It did not work. I don't even know if reinstalling XP will work because whenever I turn it on it is all black and I have to make the stand bye / Tower on Tower.

  When I have it plugged into an external monitor, I could see all starting the process (initial screen of the BIOS and Windows). I then tried to access the video driver display configuration but it would show only the external monitor. It would only detect the laptop screen after a stand bye / turn back on, and then it worked perfectly: the screen two screens simultaneously, extended, everything. Ah, changing BIOS selection automatic the LCD + external monitor does not work.

  I am really puzzled here and I can't understand it. I really don't think it's a hardware problem, because the screen works 100% after the stand bye. I guess that XP is do something during the closing down that completely 'stops' my screen, even after starting, and then I can only turn it on with the thing stand bye.

  Any help would be really appreciated!

  Best,

  Hi guys

  I had a similar problem on a series of Satellite A200 and I could solve works to update the BIOS and update the graphics driver.
  In addition, you must make sure that all available MS fixes and patches have been installed.

  Unfortunately, but that's all I can suggest. If the problem persists and you would not be able to solve update components then an ASP needs to check.

  Good luck

• Equium L20-197 does not light up at all - on button / stop flashes and nothing happens

  Hello

  I own an Equium L20-197 and it currently has a power problem. It does not light up at all. When the device is connected to the machine the orange light comes on to show that there is a power source but when I hit the power button the flash just buttons and nothing happens.

  If I hit him again once all the lights go out and the whole system fails.

  Any ideas on how to solve this problem?

  Hello

  Did you put this phone in the standby or hibernation mode?

  Read this description, it seems that the laptop has been in one of these modes and cannot wake up.
  Try to remove the battery from the laptop and unplug the power adapter.
  Several waiting time (~ 20 min) and reconnect the battery and the AC adapter.
  Then try again to put the laptop.

  If she will not be able to boot up the laptop I presume the ESF on the dysfunctions of the motherboard.
  In this case the contact of technicians would be desirable.
