When i shake my laptop, its screes becomes black

Go to BIOS and check if the screen will shake in there if not try to uninstall and re-install the video driver that you have. If the screen is also shaking in BIOS it means there is something wrong with your video card.

Make sure the internal VGA cable is connected on both ends and that the scree power is plugged in a good rule to follow when building/putting back together laptops is to try to test it with everything plugged in before screwing hope that helps =]

your screen is either about to fail or was severely pressed against a hard surface. unfortunately in most cases you just have to change it if the lines become too many. but in the mean time you just have to soldier on

I can't guarantee that you will receive a e-mail to your address, because I just work here and you must contact me through channels. Now, let us see... If you think that the computer is alive, forget it! Dwelt by mysterious ghosts, boo hoo! However a computer is a complicated machine and can think for itself and make decisions, but not like any brain of an animal or a human. Computers have to have someone make their decisions. This is actually the one thing that they can do: they follow instructions 100%, had two memories: one short term and one long term. But still they are not living beings! I am sure that your computer will be fixed and you will be very happy for it if you can provide me with the following information: Name of computer, model number, Mother Board ID and a detailed description of what happened in your own words... Even though I am sure that you know, I would like to caution you, not to tinker with any of the controls on the MB. A slight increase to the CPU chip supply voltage, can cause such a high current that certainly the heat sink of any CPU cannot dissipate the heat and the CPU chip will commit suicide. The MB ID can be found in between the white PCI sockets, or else around the RAM memory sockets. They only list the serial number. Using the serial number on the IT, you can find the name of the manufacturer. So, we need that number. The letters and numbers are so large that you cannot miss it...So, I will expect your information! Thank you for considering our service...
