  Use of AL1511b laptop computer screen 5820 T-6401 in Italy. Simple adapter or converter needed? AC adapter / CC seems to be internal. Can I just attach an adapter at the end of the wall to the monitor cord to fit Italian DC connector configuration or do I need a converter between the end of the US AC 3 earth-pin male connector and the Italian DC Jack?

• Black laptop computer screen discoloration

  Hello! I'm here because I had a problem with my laptop recently. I have a HP Pavilion G6 (don't know what year but I bought it in 2012) and for about 2 weeks, my computer screen has just been randomly fades to black.

  It is not closed, it stays on and I can still here sound, but the screen remains black. I tried to use an external monitor, but it did the same thing. Also, I get no error message like this happens.

  I ran malwarebytes and AVG, removing all he detected, but the same thing is happening. I don't know what is happening.

  I did not open my computer or anything like that. Just in case, he began to arrive.

  I hope that someone can provide an answer, it would be greatly appreciated.

  I suggest you try to do the following:

  Press Windows key + R-> type regedit-> press ENTER. Click Yes, if UAC prompts.

  See the link to back up the registry first, before continuing:

  http://support.Microsoft.com/kb/322756

  Now, in the left pane, navigate to the following folder:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

  Once you select the control, you will find a set of entries in the right pane.

  Double-click "WaitToKillServiceTimeOut" to change the value. Change it in 2000.

  

  Click Ok, close the registry editor and restart the PC to check.

  If the problem persists, try this:

  Click Start-> type cmd-> press Ctrl + Shift + Enter (to start cmd in administrative mode). Type the following command and press enter (make sure all your files are saved and all applications are closed):

  shutdown-s-t 00-f

  This stops the PC. Check the time it takes to turn it off. If the problem does not occur, change the value in the previous method in 1000 and check. If the problem persists, change 500 then check.

  If the problem occurs, it may be due to drivers. Try to update the drivers, specific display drivers. If no update is available, try to reinstall the drivers: uninstall the drivers, reboot the PC, install the drivers, reboot the PC and then check.

• Laptop computer screen problems!

  I walked on my laptop and the screen cracked, but it worked well. But NOW the screen keeps shaking so that I don't see anything on the screen. It starts and stops, and it does not occur when I use the word. Is there something I can do?

  There is no you can do in addition to the replacement of the screen; continued use may cause other components to fail. Contact the support of the manufacturer of the laptop computer about the replacement of the screen. As an alternative, you may be able to locate a known local computer repair shop to do the work; I do not recommend using one of the chains of big box stores.

• Pavilion dv6700: Pavilion laptop computer under Vista: Windows does not start, the Startup Repair cannot fix it. What to do next?

  Hello
  My laptop seven year old made me proud til yesterday, but now it does not fire upwards. Instead, it hangs for a minute or two (black screen, no HARD drive light blinks, nothing), while it charges to a screen with two options - either start the system restart or start Windows normally. The second option takes me around the loop again. The first option tells me that it cannot fix the problem automatically. When I display the error details, it lists all of the tests, as adopted successfully, but ends with the words: "Root cause found: failure so that the Setup program is underway.

  I'm sure I know why she fell: two days ago, I left all my files on a portable player and defragmented the disk. The idea was to speed up the machine and get it running like new. He immediately started to hang when connecting, so I thought, well I'll go for a complete restoration of the system. I followed the procedure using the disks provided with the machine, and that's when it stopped working completely. I felt that this was more than the aging than HARD drive could take.

  My attempts at rejuvenation have actually caused his untimely death? Or is there a difficulty - something I could undertake?

  Or should I just bite the bullet and go and buy a new machine? When everything (screen, keyboard and trackpad) worked so well, it seems a shame...

  Any help or thoughts welcome. Thank you

  If you really want to resurrect, you could certainly purchase a new hard drive and try to restore the system of work using the recovery media - but then, even if it did work, you would have still lost all your data, settings, and applications in the process - and having to reinstall all your applications everywhere again.

  Hey, don't feel bad, I'm guilty of this too - has recently attempted to resurrect an era Tablet XP PC so that it can run Win10!  He went from XP to Vista, Win7, for Win8 - and along the way, gains of new memory and drives hard - but the Win10 bet was too.  So, I got to a "give up to use it.

  However, I also kept a cell phone 5 year alive by replacing the HDD with a SSD and adding more memory.  So now it is faster than ever, it has been and works like new.

  But... He has NO touchscreen, there no USB3 ports, it doesn't have 1 GB ethernet - and the list goes.

  Thus, it works very well for what we use it for - but it can't really be upgraded, so sooner or later, we will have to replace it.

  Everything depends on how much you need 'new' - touch screen, stylus, handwriting, camera, 3 USB ports, display port jack, HDMI ports... etc.
