When it turns black take a flashlight and shine it on the bottom of the screen where the start button would be. Look closely and see if you can seen any faint images there. If you do then your backlight is malfunction. That typically is not a self-fix for the typical user.
If you don't see anything can you give us some more information.
- Are any lights flashing just before or after the screen turn black?
- If you restart the computer will it work again?
- Will the screen go black even if you are actively working on the computer?
If its not the backlight let us know the answer to these questions and we'll continue. As always please don't forget to rate this posting.
Locate for a Switch with a WiFi symbol (Ususally, a Tower with emitting rays), press it (In many laptops, it will get lit when pressed), turn on your WiFi Router and wait for it to be detected, when your Laptop informs you of it, then connect it by double clicking on its icon or choose select or connect.
THE EXTERNAL WORKS ? IF YES MAYBE IS YOUR INVERTER DISPLAY DEFECTIVE. IF NOT YOU HAVE PROBLEM WITH YOUR CHIP GRAPHICS ON MAINBOARD AND NEED REPLACEMENT
I have installed the pack numlockx, activated it with the procedure described on ubuntu.org. Then by making CTRL SHIFT VerrNum (ubuntu.org procedure), the numeric keypad that had been inefective for one year began to work again...
Might be there is a battery problem start it with power cable plugged in. Or avail the service of your manufacturer, if its under warranty you can get it replaced.
Are we talking about the NEC Versa P7200?Let me see if I have this straight..........Turns on, just shows a blue screen, then shuts off.That about it?Virus?I would be more inclined to say the laptop is dirty inside.Air is used to cool the hardware components inside a computer.Basic cooling system consists of a Cooling Tube, Heatsink, and Fan Assembly.Cooling Tube:Slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.Has a metal plate, or plates; attached to one end.Heatsink:Small strip of metal that has Tall, Thin, fins protruding from it.This is mounted to the opposite end of the Cooling Tube, from the metal plate/s.Fan Assembly:Small multi-bladed fan sitting in a D-shaped shroud.Let's look at an example, (Not for yours),http://www.ebay.com.au/itm/NEW-NEC-Versa-S900-Fan-Heatsink-GC054009VH-8-V1-B492-M-/270295120853?pt=US_CPU_Fans_Heatsinks&hash=item3eeed83bd5Two views are shown.The view on the Right is a Top View.Let's refer to it, with references also to the other view. The Bottom view.At the bottom you see a rectangular shaped piece of metal, with 4 holes in it. One in each corner.For this particular model it sits just on the Processor.Heat is absorbed by that metal plate, and the curved copper Cooling Tube absorbs heat from the metal plate.The Cooling Tube then transfers the heat, to the rectangular shaped finned Heatsink.The Heatsink absorbs the heat, then radiates it away with it's Tall, Thin fins.Air flow from the Fan Assembly, helps carry heat away from the fins of the Heatsink.If the fins of the Heatsink are blocked off with 'Gunk', and also the fan blades; the laptop overheats.['Gunk' = Dirt, dust, hair, lint, food crumbs,....you name it ]This is an example of a laptop that is dirty inside,http://www.youtube.com/watch?v=AkAeE5I5E_AYou can see this model has 3 Cooling Tubes, and metal plates; plus 3 Heatsinks.(0:46)When a Processor overheats it turns off. (BIOS turns it off)This is a fail-safe feature that is built-in.Keeps the Processor from burning up.Also the Thermal Paste dries up from overheating.And Thermal Pad.(A Thermal Pad is a material that is impregnated with Thermal Paste)Thermal Paste is used on top of the Processor, most of the time.Other times a Thermal Pad is used instead.A Thermal Pad is generally used on a graphics chipset.For additional questions please post in a Comment.Regards,joecoolvette

Restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer As the computer is booting repeatadly press the F8 key as the computer is booting If done properly the user should get to a screen similar to the below screen. Select the option for Safe mode command prompt only Windows Advanced Options Menu Please select an option: Safe Mode Safe Mode with Networking Safe Mode with Command Prompt Enable Boot Logging Enable VGA mode Last Known Good Configuration (your most recent settings that worked) Directory Services Restore Mode (Windows domain controllers only) Debugging Mode Start Windows Normally Reboot Return to OS Choices Menu Use the up and down arrow keys to move the highlight to your choice. select safe mode with command prompt Then type at the C:\> prompt: type DEBUG and hit Enter.

Finally type: Quit and hit Enter one last time to quit DEBUG back to the C:\> prompt. Now you're ready to reboot your PC, and press the appropriate key or key combo (look it up in your motherboard manual if you don't know it) to access your BIOS Setup. Youll notice the password is gone. If this fails try typing At command prompt type debugyou will get a - prompt where you can type the following (<enter> means press enter, not type enter*) A <ENTER> MOV AX,0 <ENTER> MOV AX,CX <ENTER> OUT 70,AL <ENTER> MOV AX,0 <ENTER> OUT 71,AL <ENTER> INC CX <ENTER> CMP CX,100 <ENTER> JB 103 <ENTER> INT 20 <ENTER> <ENTER> just hit enter on this line G <ENTER> Q <ENTER> Basic BIOS password - works 9.9 times out of ten If this fails you will need to Select safe mode with networking to download you could download all of these or just one save them to a usb drive for later use if one fails to remove the password http://www.tech-faq.com/reset-bios-password.html At some stage you might need to press Ctrl+Enter rather than just Enter if on a Dell Latitude E5410 http://majorgeeks.com/CmosPwd_d239.html A CMOS BIOS password recovery tool Editors note: This tool should only be used by experienced computer users. Please see the enclosed read me if you would like to run it from Windows. Failure to follow instructions (from Windows) will cause your anti-virus to flag this as a virus. Hope this helps.
What is your question? The volume is located in the Tray Notification Area, Sound icon, right click, adjust volume.OR , open Control Panel, Sounds, adjust.
Several memory vendors will help you find the answer. I like http://www.crucial.com/store/drammemory.aspx It walks you thru finding how much and what kind of memory you have and what you can install.
