My lenovo screen goes black on rebooting and then write thinkcentre what should i do


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.

Hp pavilion dv7-4165dx black screen


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.


Hope this helps

Help please, just replaced lid on emachines d620, all went well, just turned it on and screen is completely black. The logo shows very feigntly as it powers up, boots up fine but completely black screen.


It sounds like the cord connecting the lcd screen to the laptops motherboard has been disconnected. You will probably have to disassemble the screen portion of the laptop and reconnect the power wires.

Toshiba Satelite P305 Laptop gtoes black. How to solve that? It was working fine and suddenly I turn it on and though I can see the on lights the screen remains black.


Hi.
Try this: Press and hold down the power button for 10 seconds, let go and wait for a minute before powering it on again.
This procedure will reboot the laptop from its internal power supply. I hope this helps. :-)

My Aspire One netbook seems to be frozen. Screen is black but I cannot turn off computer. It is 751H with 11.6"screen.


Well try hold down the power button for at least 10 seconds until the laptop powers down. if this doesnt work, pull the power cord out to the laptop and take the battery out.

Put the battery back in the laptop and power up.
If u still just get a black screen whist the laptop is on after that its most probably the graphics controller that has malfunctioned.

If that is the case, call ur local Acer hotline and the will come and collect and repair and return if still under warranty.

Well my toshiba satellite u405-s2820 turns on but the screen is just black... what I'm I to do??


Firstly unplug everything from the laptop (even the power) and remove the battery, hold the power button down for 10secs then plug the power back in only, see what happens...

If nothings changed...
Try and plug a normal monitor into the VGA port and turn the laptop on;
you will get the toshiba POST screen if the graphics card still works (then the actual screen is at fault)
if you dont then the graphics card is at fault..


[Just a thought... does the laptop bleep when you first turn it on?]

Let me know how you get on...
