Blank screen will not turn off


You turned on your laptop and horrors upon horrors, the screen is BLACK! You see that the laptop has power but besides that nothing is happening. I want you to know that there is a very good chance you can get out of this situation quickly and without any cost. This fix works on all brands of laptops:


• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up. Replace your battery.

A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,
if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black. Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.
Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.
Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.
Trace the cable coming from the laptop screen to the connector found beneath the bezel.

Reconnect the display cable to the motherboard if the cable has come loose from the connector.
Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on.

If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective.

If the external monitor works, the LCD screen could be broken.

If the monitor doesn't work, the motherboard or video card might need to be replaced.

When I open my laptop, I have to press F2 but could not enter the bios, the screen becomes dark and went straight to windows. what should I do.


From the symptoms, it could be a faulty keyboard -

First though, are you pressing the F2 key soon enough?
I'd turn on the notebook and then start pressing the F2 key repeatedly.

If that fails, I'd borrow an external USB keyboard to test it with first and see if it does the same thing....

Often, if the keyboard has had something spilt in it, or it has come loose, of just failed, the keyboard will not respond to any input.

If, under windows, the keyboard works fine, then that may not be the issue... if it fails under windows, you'll probably need to replace the keyboard - usually pretty easy and cheap enough to do.

"the screen becomes dark" - too dark to see? or just dimmer, as if you took out the battery charger?
if you cannot see it at all, or just barely see it - the screen inverter may have gone, or the backlight in the lcd panel, or the cable from the mainboard to the inverter...

If you are still having trouble, feel free to provide some more info re describing the dark screen issue...

Hope this info helps.

My laptop boots but nothing appears on the screen


You can check this by connecting a pc monitor to the spare VGA port on your lap top and switching the screen output. (Fn and one of the number keys with a screen on it)

If the picture on you spare monitor is good, your graphics card/chip is good, if not, you've located the problem.

If you do, get a good picture on the spare monitor, switch back to your laptop screen and look closely at the screen while, is there a very faint/dark image. If so, your inverter has failed or become disconnected. If nothing, your screen has failed or become disconnected.

You can possible check these connections yourself, if you're not handy with tools then don't because its delicate work and you need to be careful to prevent further damage.

Disconnect all forms of power - batteries & ac adaptor.

Give yourself plenty of time and space.

Open the laptop, there should be plate between the keyboard and the screen. This is usually screwed and clipped into place. So remove any screws, may include the back of the screen hinges. Then prise up, very carefully, the plate, look for more screws or resistance as you go, you don't want to break it. Eventually you should overcome all the small clips and remove the plate.

Look for ribbon connectors, probably 2 or 3, check make sure they're all home and good. If one is loose, then re-attaching it properly could well be the cure to your problem.

If they were all connected properly, then you've probably got a failed inverter. Needs replacing and this is where I stop, you need a diagram or repair manual.

Coloured lines on my screen


What type of notebook is this. Most dell models you can remove the plastic power strip above the keyboard. You need to lay your notebook screen flat so it is level with your keyboard then use a flat head screwdriver to gently pry open the bezel from the left hand side. Once that is off you can remove the two screws attaching the keyboard. Then reseat the lcd cable which should be in the cetner. Have you tried connecting your notebook to an external monitor. If that does not work then your video card is bad.
