For such a relatively small device, a lot can go wrong with your laptop or computer. One of the more frustrating things that could go wrong is when your screen won't turn on. You may find that your fan is working, but there is nothing on your display, or there is just no signal. This is occasionally referred to as the black screen of death (bsod), fortunately you should be able to fix it. If your computer boots to a black screen here are a few ways that you could remedy the problem.
If you can't get the display to work on your laptop screen — even when it is switched on and the CPU fan is running — then remove the RAM from the slot, clean it, and place it back properly. (You can also try inserting it in another slot.)
Note: Before touching any of your PC's internals, remember to ground yourself to remove any static electricity.
If you have two RAMs inserted, then remove both and replace only one. If you check the display and it still isn't working, try switching out the RAM. If you are replacing the RAM, make sure that it is compatible with your computer's specs.
If the problem persists, then try connecting an external monitor to your laptop. Simply look for the VGA connector (there will be a monitor symbol) on your laptop, and connect it to the external monitor. Then turn your laptop on.
If you find that the screen works normally (it doesn't turn black) in safe mode, then there is probably a corrupted drive for your video card (safe mode loads the generic windows driver and not the one specific to your card).
If your computer is starting normally, but then as soon as Windows has loaded, the screen goes black, this solution could help. Before you try to replace a graphics card or do a reinstall of an Operating System, Check to see if the jumpers on the hard drive are set to master.
This is a small clip that sits in pins on the back of the hard drive. Cable select could be going out and cause the same symptoms. If you are not sure how to set a jumper just google it for directions and it should help, but hard drive a labeled. CS-for cable select, SL- for slave, and MA- for master.
Do you have a black screen, except you can see and move the cursor? In this situation, typically ctrl+alt+delete and doesn't respond, and rebooting to safe mode results in the same black screen.
and press Enter.
If shell and userinit are having different data values then change it as mentioned above. Just double click shell and userinit and enter the data values as shell --> "Value data" should be Explorer.exe
Once you have done this, download some form of anti-virus software. We recommend Malwarebytes Anti-Malware. Update to the latest version and perform a Full Scan - the default is Quick Scan, so you will need to select this option.
If you suddenly notice a change in resolution, as if the computer has started up in safe mood, and then opt to change the resolution (above 800x600 in some examples)- you may find that the screen goes black. A quick fix for this is to immediately press the F8 key after the start up screen, and selecting Enable VGA from the menu. You should then be able to reset the resolution and resolve the black screen issue.
