Problem with a HP Laptop. When switched on, the screen stays black and after about a minute, the computer restarts itself (screen remains black). It just continues doing this. After a few days, the computer started working again, but this time it has not. It has done this about 3 or 4 times. Have you any ideas as to what the problem may be?

This video shows you how to restore the BIOS in your computer:

you have sleepsettings set to start button, set it to shut down.

It may be a couple of things, inverter, backlighting, the switch that controls the display when you open and close the lid. Here is a video to help you troubleshoot the issue: http://www.youtube.com/watch?v=2Yi6GNFcP3w Have you cleaned the fan, vents, heatsink recently? Take a look at this: http://www.techradar.com/us/news/mobile-computing/laptops/how-to-clean-your-laptop-of-dust-and-dirt-942783

To do a power reset, unplug your laptop, remove the battery and hold the power switch down for 30 seconds.

otherwise it may be problem with your screen back light...

The problem could be the backlight or its inverter is bad. IF picture remains but lights only go out. Also it is normal for the screen to go black if the laptop is not used.

If the picture itself remains on the display but it just goes dim, try turning up the brightness, if noting happens, most likely the backlight of the screen or its inverter is or has gone bad.

Would need to be confirmed in person.

If the picture does not remain on the screen and the laptop shuts off, your charger might not be working, and your battery is low.

Would need to be inspected in person.

1) Switch on Laptop
2) Immediatley press the F8 key continuoulsy until a advanced start up menu is presented
3) Choose safe mode

Take out the Battery and power plug then put them back and try starting the computer again. I hope this solution was helpful.

Well are 2 reasons for this behaviour of your notebook...first it can be an issue with the graphics card installed on the motheboard or its an issue with the Monitor cable which is connected between the motherboard and the LCD.

Following are the steps that you can try to resolve the problem:

At first we need to check whether its a hardware problem or not.

1.Restart the computer and tap on the F10 key for a while which would take us to the BIOS SET UP UTILITY...

2.Now we need to wait for sometime in this screen so that we can check the status of the screen whether the screen goes dim or it remains normal..

3.If the screen remains normal for around 10 minutes then its not a problem with the cable,

4.Now we need to get back to the windows screen and try installing the graphics driver for the notebook.

Let me provide you a couple of drivers for the notebook.

I am providing you the drivers assuming Windows Vista installed on the system

if you have an ATI card installed, the install the below mentioned driver:

if you have an NVIDIA card install the below mentioned driver:

or you can install the drivers directly from the manufacturers website..


Hope this works.

Check all you cables etc.. If this does not correct the problem it is most likely the video card integrated on the motherboard.
I had a dv1000 do the same thing. The bad news is the motherboard will have to be replaced.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/robert_33deecd2f8e91168

Completely remove the battery and unplug the power cord for a few minutes. Reinsert battery and power up. You can also hit F8 when starting and see if you can boot into safe mode.
