• HP 15 laptop: flickering horizontal line at the top of the screen

  Hi, I bought this laptop 10 months ago and its been great until about a month ago. A month ago the hard drive doesn't work faster (Super slow r/w) and is noisy. 2 days ago a horizontal line at the top of the screen started flashing when I started the PC. Then I rebooted a few times and nothing. I finally found it flashes only when the pc is unplugged. I loaded 100% and it continues to blink. Update my display drivers did not help either.

  Video: https://www.youtube.com/watch?v=7zJioGvs2Bg

  In the video you can see lines flicker. When he started there was only one, but it has gradually increased to 4 sound at this time. Also, the line crosses the screen completely but is no longer visible to these 4 points.

• Dv6 7246us horizontal line on the screen

  Hi all

  I have a DESIRE DV6-7246us, just updated to upgrade to 8.1 WIndows, yesterday, display fell asleep and trampled, I now have a flickering horizontal line at the top of page 1/3 of the screen. It is a single horizontal line that appears to wrap the text what ever he is going through, around the other side of the screen.  windows 8.1 upgrade was completed Monday, and the line began yesterday.  The computer is stock, with a genuine copy of Windows.  Please help I have runa small business, and this computer is invoked daily.

  Thank you

  Hello again,

  I could solve the problem with an updated graphics AMD HD SP60282 driver.  The only horizontal line has disappeared since I updated the driver.  Previously, it did not matter if I rebooted or the monitor kept awake, it never disappeared.  Now everything works as it should.  The driver can be found by searching SP60282 on the HP site.

  Thank you!

• NB 550 d - 11 d - horizontal line in the middle of my screen

  I have a toshiba NB 550 d - 11 d a few weeks ago.
  It has been very slow since the beginning.

  Then, the fan has started to be marketed all the time and now I see a horizontal line in the middle of my screen.

  Hello

  I fear that the problem is related to a hardware problem m.
  The internal display is affected or the graphics chip on the motherboard is faulty.
  In both cases the hardware must be replaced
  Therefore, you should get in touch with a partner service is available in your country for this problem
  I hope that your warranty is valid

  Good luck

• Satellite L830 - horizontal line across the screen

  All new Satellite L830 has a horizontal line across the screen.

  What can be the cause and how can be fixed?

  If the laptop is brand new it back as soon as possible and ask for replacement.
  On this virtual path, it is not easy to say what the problem is here, but it may be related to faulty display, especially if you can see from the first moments when the laptop is turned on.

  Don't try anything. Request a new one. If you can not new, contact the nearest Toshiba service provider and ask for help. They need to exchange the defective part.

• Satellite Pro M10 - horizontal lines on the screen in different areas

  Hi all

  I hope someone can help.
  My Satellite Pro M10 seems to suffer a display problem where I have horizontal lines on the screen in different areas.
  It would be well for 10 minutes and when the laptop seems to warm up this problem begins, then shortly after
  The laptop would crash and enter in a resolution of 800 x 600 16 colors or sometimes freeze.

  Graphic drivers have been resettled, and even a new installation of Windows XP from the recovery CD does not help.
  A reboot doesn't solve what the same thing happens again and after one minute of use, so I thought it might be a video or cooling problem.
  I changed the video card I had a spare part of my last motherboard hoping this would solve the problems, but the problem persists.
  Perhaps a cooling problem? Or problems of motherboard?
  The motherboard has been replaced twice, hoping that this isn't another mobo problem.

  Any advice would be great.

  Thank you.

  Hello

  I m not 100% sure but to me it looks a bit like an overheating problem
  Maybe the graphics card may not be properly cooled after a certain period of time and that's why these strange horizontal lines appear on the screen.

  I wonder how you were able to replace the graphics chip on the motherboard?  :|
  If I m not wrong not the chip is fixed and the replacement is very easy and difficult

  It of always difficult to say what's maybe wrong without running several diagnostic tests in most cases this problem may be related to the defective chip or motherboard and so the following should be checked

  Sorry, but that's all I can suggest.

  Best regards from my friend

• HDMI output on Qosmio G40 - horizontal line on the screen

  I connect my Qosmio G40 to an 46F86BDX of Samsung LCD via HDMI. On all my films, when there is a shift, I see a horizontal line on the screen. Sometimes is in the middle of the screen, sometimes lower.

  I tried my pc with another TV and a different cable, but the same problem. Someone knows the same thing?

  Thanx

  Hello

  > On all my films, when there is a shift, I see a horizontal line on the screen.

  If I understand issue you this horizontal line appears ONLY on and external TV and ONLY if there is some faster movements of the pic.

  If so, then I think it has nothing to do with G40 Notepad.
  I have read that those issues could be related to the new TVs LCD then to watch movies in high definition.

  I think you should read a few tests and reports on similar issues on LCD TVs

  See you soon

• HP EliteBook 8440p: white horizontal lines on the screen who retreat down in the minute

  Hi again. I've already posted about this so there are pictures and a full description of my post a few days ago. In short, when the laptop was arrested or sleep for more than a few hours, it is white horizontal lines on the lower part of the screen that slowly fade completely down. The lines do not appear on an external monitor in dual mode.

  I removed the screen twice now and checked / reinstall connections to the screen and under the keyboard. The problem persists.  I flashed the BIOS a few days ago and the problem persists. The webcam, microphone and WWAN/WLAN are all in perfect condition and the computer works fine apart from this problem of screen work.

  Until I drop the most money on this used laptop that is my only question at this point sounds as strictly a matter of cable/display on the screen? If it's a motherboard problem I would see other problems? If it is the graphics card goes wrong I would see other problems? As I said, the computer works perfectly once it is running.

  Anyone has any useful ideas?

  Hello

  You can try to connect this unit to an external monitor to check if there is a problem with the motherboard or display

  If the external monitor works fine, then there is no problem with the motherboard, only the display panel needs replacement.

  If the problem persists in the external monitor, suggest you to update the graphics drivers and see if the problem resolves

  I hope this helps

• ProBook 450 - second series of recovery media, blue screens windows 7 (win 8 okay, not the hardware problem)

  I had a new HP probook 450 G1.

  Immediately, I swapped the 750 GB for one SSD drive and tried to install Windows 7 from the recovery media. The operation has failed. Contact HP support, they sent new media.

  I used new media. Windows 7 operating system installed. As soon as I install the drivers, the PC goes in a loop of the blue screen.

  I can install the chipset drivers and wifi. Don't know what the other driver is causing the blue screen. I can also install from the windows media 8, so this isn't a hardware problem - wife hates just windows 8.

  Basically, please either give me a few troubleshooting steps or I'll go back to the PC. I'm NOT insterested in a manual process long to determine which driver is the problem and the recovery download media manually the drivers one... should work.

  After you have reinstalled the original 750 GB hard drive with the replacement media, I managed to an attempt to "recover". So, I decided to sit and try, by the process of elimination, all drivers.

  It turns out that the technology Intel Rapid Storage Technology driver was causing the problem. When I installed everything BUT that, the laptop works very well. Notice that I use a fairly new SSD Crucial of M500. It is quite possible there are other people out there see it. You really need to install the driver of rapid storage technology, it is fast enough - not not even 100% sure what good to give the driver.

  So I gave myself wrong guidance by the initial recovery of defective media. The second group of work recovery media, but the version of the driver intel 12.7.3.1001 does NOT work with the Crucial M500. I checked the Intel site for driver downloads, and it was not clear that they have a newer driver appropriate right now. Maybe someone else can tell?

  This means that the LCD screen of your laptop will have to be replaced to solve the problem.

  External display display normal display shows that the solution to video display inside the laptop (integrated in the chipset or graphics module) is operational.
