Try pressing the power on button for like 10 seconds. it should really turn off the notebook. wait like 30 seconds, then turn it on normally. it should start.

if you have the notebook connected to an external display, disconnect the external display first.

Laptop black screen


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.
or if wont start
Here are the fix steps:
1. Turn off your computer
2. Disconnect every wire from it (including power)
3. Disconnect the battery from the bottom of the computer.
There will be two tabs labeled 1 and 2.
4. Re-plug in the power wire. (the battery should not be in the computer)
5. Turn on the power. The screen will work. Choose start windows normally. (if you get that screen)
6. Go to Control Panel -> (Mobile PC) -> Power Options -> Under Balanced choose change plan settings
7. Choose Change advanced power settings
8. Find Processor power management and change the minimum processor state from 5% to 100% for each On battery and Plugged in.
9. Click Apply then OK
10. Shut down you computer.
11. Disconnect the power cord.
12. Re-install the battery on the bottom of the laptop, plug in the power cord, and restart the computer.

Screen wont come on, on my Toshiba laptop computer


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.

One thing to try is if you can, connect an external monitor to the computer. Turn it off and then back on with the external monitor on. If video on the external monitor then the problem is with the laptop monitor most likely the FL inverter or the lcd itself. If no external video, it is most likely a motherboard problem.

To verify that your laptop is function and the monitor is now. Try plugging your laptop into a regular computer monitor. If the computer turns on and displays an image on the secondary screen, then you'll need to look into having your laptop screen repaired.

This could be either that your screen has failed, or has just become disconnected somehow from the screen to the laptop motherboard on the inside of the unit.

Computer turns on but screen stays black


This is often caused by the screen lights or screen failing. Try looking at the screen from different angles in different light conditions, you might just be able to see the image.

Right click anywhere on the desktop, open the screen saver tab, click on the power button at the bottom. You'll see a box that reads monitor, set this to never. That should take care of the screen shutting down. As far as the orange light, I'm guessing that's the battery light, and it's time for a new battery.(It should be green and flashes orange when the battery no longer works properly)
