Black screen for hp laptop

I have a hp pavillion dv000 laptop that I have used for about two years or so and all of a sudden its screen just went black...nothing. I cant even see a resemblence of my desktop when i turn it on although if i press the sleep button i can see the display for about a second. but, everytime i press the button it puts my whole computer in hibernation.

I dont know if the problem is my backlight, inverter, or my lcd, and even if i did i wouldnt know how to go about fixing it. I want to replace it completely with another laptop but there are some very important documents that i want to transfer over to my external hardrive first but cant because i cant see anything on it.

i thinkig about hooking it up to an external monitor another laptop but dont know how or what cord i would need to do that with. If that doesnt work, would i (or somebody else) be able to take out the C drive and put it in another laptop?

Thanks

Hi,

Initially, a couple of ideas ou may want to explore:

  • hook an external monitor. Often there would be a VGA connector at the rear of a laptop specifically for this purpose. It would need a standard 15 video cable normally attached or with the external monitor. You may need to cycle through Fn + F? keys to enable the external monitor. F? would be the function key with the small monitor icon;
  • remove the hard disk of the erring laptop, connect it to a 2.5 to USB adapter and attach to a free USB port of a 2nd computer. it will be treated as an external storage device much like a thuimb/flash drive and therefore would allow copy and paste;
  • tap on the cover of the laptop, the one right behind the LCD screen anywhere on the sides, this is in the hope that it is a cold solder or loose connection;
  • run the laptop with the lid not fully opened;
  • slightly warp/twist the lid/LCD, it could just be a loose connection;
  • if the display works even just momentarily, then chances are that no major repair work is required. The bulk of the job would be in the opening and offhand, no major component replacement.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

  First of all the backlight, inverter, lcd is not the problem if you see any display, even for a second. An external monitor connects just like it would for your desktop computer -a 15-pin connector -the only connection for an external monitor. Do that connection while the computer is off! Fn + F7 switches between the lcd internal monitor and the external monitor if you do not see a display at boot on the external monitor. If you find that the video card/motherboard is history then the internal hard drive can be removed and connected to another laptop or desktop computer. There are inexpensive adaptors or hard drive cases that allow you to connect that drive to any computer. If you are not interested in doing that then you can also take that hard drive to a computer shop who can easily transfer that data to another hard drive, burn a cd/dvd or put it on the internet for you to download with another computer.  The only consideration for putting the hard drive in another laptop is that you cannot boot from that drive on another laptop. If you use an adaptor to connect to a desktop then that hard drive will be a removable disk or slave, never the primary boot drive.

Ihave an hp pavillion laptop where the screen went black and need a solution to fix


First hook a spare monitor to the video output jack usually on the back, if picture comes up! it indicates a bad inverter board, or the backlight has stopped working, if the spare shows the same problem, it means the video graphics card is defective and normally built into the motherboard.

its the common problem with graphic card, if its nvedia chipset graphic, there is only one temp solution, ask any hardware machanics to put a glue and heat the display ic, then it would work for a week, in that period buy the amc from hp service centre, after a week if there is a prob, company will have to replacd the motherboard

Screen dim to black


This will be a problem with either the screen inverter or screen backlight. You will need to take it to a shop for diagnosis, in order to find out which one it is. If it turns out to be the backlight, then the entire screen will have to be replaced. They are considered a sealed unit, and the backlight can't be changed out.
