• HP pavilion Beats: Hp pavilion bat screen black at home but I can see the mouse

  When I turn on my hp Pavilion beats edition that works perfectly well. But when I put my password it loads and then goes black. I can still see the mouse, but not the screen. I rebooted several times and I'm out of ideas.

  Hello

  Try the following.

  Boot the computer normally and log.

  Black screen, hold down the ctrl and alt keys and press delete.

  Select Task Manager.

  Click on file and select the new task.

  Type rstrui - also enter a tick in the box for "create this task with administrative privileges" - and click on Ok.

  When the system restore interface is loaded, choose a restore point at least 48 hours before the log - it occurs first and then proceed to the system restore.

  If the above is not correct the problem, try to run the steps in the link below.

• Empty the Pavilion dv4 screen. CAP and lock number will Flash 3 times

  I have a pavilion with a white screen dv4.  The cap and number lock led's will blink 3 times.   I tried to remove the memory and restart with a single in a slot, then in another location, and then Exchange and repeating.  Still no change.   I removed the battery and power supply and power button that stood for a minute, and then tried to restart and still no change.  Any other ideas?   Or is she dead?

  with these symptoms, I guess it's a problem more serious. For troubleshooting, please contact any nearest repair center.

• SCREEN BLACK WITH WHITE AFTER START POINTER

  I went on vacation and turned off my computer.  When I got home, I stupidly plugged in my blackberry storm, while the system was starting the system.  Now all I get is the black screen with the white pointer stupid.  I tried the solution of Task Manager and a few others who were listed in the similar questions to no prevail.  At one point I did a boot repair tool and he returned with it could not repair the iso standards, ico or something like that.  I did a system restore to an earlier date to before I left and that did not help.  Please help me.  Thank you.

  Hello

  You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel - device
  Manager - graphics card - Double click on - driver tab - click on UPDATE driver - then right click
  on devices and UNINSTALL - REBOOT.

  Another method to try to get to the desktop (try in normal Windows Mode without failure)
  CTRL + ALT + DELETE and on the tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - then
  on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is reached
  by tapping F8 as you start several times.

  First check this thread in case it is simple and if not to come back to this thread.

  Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
  That there is no information on a black screen as it is on a blue screen just adds to the
  Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a
  Google to see the proposed repairs, whom some have worked however these cover a wide
  field efforts.

  Here's a video of one of them.

• Satellite C850D-10W - upgrade screen, black Win10, bios not start

  Hi all

  I have a Toshiba two years C850D-10W, which came with Win7 Premium. After several months of flashing notice suggesting to upgrade to Win10, I decided to give it a go. I was stupid enough to not not to check if my phone would support these updates, and I have not discovered too late that it would not be on the official website.

  This subject happened is that during the installation process, to halfway through (maybe 43%) I got a message saying that the system should reboot several times. The problem is, it never exceeded the stadium to restart, and the system is now in a loop by which underscore fixed unblinking appears in the upper left corner and stays there for about five seconds. Then the system restarts and underscore appears again, and so on for ever, no logo Toshiba, no chance to select Safe Mode, nothing. I can enter the BIOS menu and I tried to boot the system from the backup DVD I did when I bought the computer so I could go back to Windows 7 but it does not work, the system just does not recognize. The HARD drive is fine, I got out and opened it on another computer as if it were an external hard drive and all the files are still there, but I can't do anything else.

  Any help would be much apprectiated, thanks a lot

• Windows Resume Loader black screen on HP Pavilion dv4-2145 dx laptop Windows 7

  I have a HP Pavilion dv4-2145 dx laptop with Windows 7. After pressing the button "on", the logo operation windows says its "recovery" windows, but a black screen titled "Windows Resume Loader" appears with the following message:

  The last attempt to resume the system from its previous location failed. Attempt to resume again?

  With the 2 following options:

  1. continue with system summary, (which does not work and I end up with the resumption of the "Windows" followed a blank black screen...)

  2 Delete restoration data and proceed to system boot menu (I haven't ' truei stops because I wasn't sure what that meant)

  But I managed to go to the reviews section diagnostic systems and it seems that he pass all 5 of the test, including hard drive and memory, poster, etc. So I don't know what the problem...

  Please notify.

  Thank you very much!

  Hello

  I think that in this case, you will have to choose the second option - "Delete restoration data and proceed to system boot menu" and see if that fixes the problem.  If all etc. documents you had open before hibernation were saved, then you should not lose anything.  If there are unsaved changes (for example if you have added to a document), the file will be to the point that his last record and you lose additional data.

  Kind regards

• Pavilion dv4-2155dx screen shows no info on the first boot

  My machine generally works very well, except for one annoying thing: on my previous Pavilion (dv4-1435dx), he showed the HP logo and a message that made me know I could press F2 or do anything to get into the BIOS setup screen.

  But on this machine, all I get is a black screen, which makes it very difficult to know when to start press any function button is necessary.

  Is there a way to turn it back on, or it has never been available on this model?

  If someone knows something, your help is appreciated!

  _______________________________________

  The PDADoc!

  I think that HP this disabled by default on new versions of the bios, use F10 to enter the bios and see if there is a setting, you can change to return to the home screen, or press ESC to show for this start-up cycle.

  Key to the new laptops HP options, everyone can work on your

  ESC = Boot screen

  F1 = Information System

  F2 = System Diagnostics

  F9 = Startup Manager

  F10 = Bios setup

  F11 = HP System Recovery

  F12 = Network Boot

  After using F10 to enter the bios use F9 to load the bios default settings.

• Screen & player stalls voids on Pavilion dv4-2045dx

  Having formerly operating Pavilion dv4-2045dx a friend.  When turned on, no screen activity is displayed.  Hard diving turns upward, but not for very long, so it doesn't seem as if Windows is actually behind the empty screen loading.  I tried to connect a monitor to the display port, but nothing appears on the external monitor or integrated display.  The command has been removed and the data seems to be intact.

  I guess the screen is dead and with it the computer.  Any suggestions before I tell him, is it time for a new laptop?

  Physically, you need to open the case and look at the type of processor before ordering a new. I'm not sure of the dv4 on top of my head, but some use laptops that are welded on the processors and you should replace the whole Board. In addition, with processors, you might be able to get more life out of it by scraping of old thermal compound on the CPU and the heat sink and thermal paste new application.
