  • flottepige Nov 28, 2007

    I have experienced the same problem. Not sure what to do.If we pull out the HD and let it set for a couple of weeks and try turning it on all is well again for a couple of days. Runs great otherwise. Just every few days it will freeze, turn off and not be able to turn back on. It will try all lights come on, no sounds except for the sound of a trying to boot noise. Any great suggestions. Motherboard issue? Overheating? It is running a recently clean upgrade of HomeXP from the original installed ME. Help if you can.

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.

Black screen when turned onno display


There are several reasons that your Toshiba laptop screen may not come on, even if the laptop appears to be running, and several options you may try to get your screen back up and running without an expensive service call.


Common causes for a blank screen include a backlight that is turned off, a display toggled to an external monitor and improper shutdown errors.


To avoid blank screen errors after your current error is fixed, make sure to follow all instructions in your user's guide to care for your Toshiba computer.


Shine a flashlight directly at your screen and look for an image.

If you see one, this means the backlight on your laptop is off but the screen is still working. This backlight normally turns off only when your screen is closed.


Look for a small metal or plastic pin near one of the screen hinges.

The screen pushes this pin in when it is closed, so if the pin is stuck in the screen closed position, the backlight will remain off.


Tap the pin several times to release it.

You may need to use a small object, such as a pencil tip or straightened paper clip, to reach it on some models.


Monitor Toggle


Press and hold down the "Fn" key if you do not see an image when you use the flashlight.


Tap the "F5" key several times while the "Fn" key is pressed.

This will cycle your screen through the various options that toggle the display to an external monitor.


Attach an external monitor, restart the computer and try this method again if no image appears on the laptop screen.


Click "Start," "Control panel," "Hardware and sound," then "Device manager "using the external monitor if you get an image there but cannot toggle the image back to your LCD.


Select the "Monitor" option to expand your selection and select your LCD monitor from the device list.


Click the "Driver" tab and select "Update" to update the driver, as this error is likely caused by a software driver error.


Force Restart


Press and hold the power button until the computer shuts down completely.


Check the indicator lights at the edge of your laptop to see if the computer is truly off or if it has simply gone into hibernation mode.


If it is off, all lights will be off except the battery-related lights if you have a charger plugged in. In hibernation mode, the power light will blink slowly.


Press the power button to restart the computer again after leaving it off for 15 to 20 seconds. This may fix the problem.


If the blank screen returns or you get a flash of images and then a blank screen, move on to the next step.


Force Power Down


Unplug your laptop from the power source.


Remove the battery by pressing outward on the battery latch and pulling the battery unit completely out of the computer.


Press the power button several times to completely discharge the computer.


Replace the battery and plug the computer back in after about 30 seconds.


Press the power button to turn on the computer.

If you get an error screen upon startup, choose to restart Windows normally.

This error is caused by improper shutdown procedures.


Hope this helps

I have a samsung syncmaster 943NW which goes on for about 5 seconds and then just goes black. When restarting the screen it does the same again, goes on for about 5 seconds and then black. Is there...


I had the same problem with this monitor (Samsung 943nw)
When turned on it would only stay on for less then a full second.
When shining a light on the screen I could see what was on it, so it was just the backlight that was shutting down.

After I turned down the brightness of the monitor, the next time I powered on the screen the backlight stayed lit and it was back to normal.

Hi rkrkeanz,

Black screen issue often caused by display problem. The easiest way to resolve this is by doing a power drain. Here are some steps that you can apply on how to perform a power drain.

--> if system is currently on, please press the power button for about 5-10 seconds to be turned off completely.

2. Unplug the AC adapter from the power outlet.

3. Take out the battery from the system.

4. Now, please press and hold down the power button for about 15-20 seconds.

5. Plug the AC adapter and put back in the battery.

6. Turn on the system.

Hope it helps.

The Startup repair program is running and wont stop


A complete scan can take several hours to complete. If you want to shut it all down unplug it and remove the battery. Leave the battery out for at least 10 minutes, and until it cools down.

Starlogic 20 inch widescreen monitor screen keeps going black


This is probably a back light problem. Take a bright flashlight and while the monitor is on, point it at the LCD and try different angles, etc. If you can see an image, it is the back light, probably the back light voltage converter unit in the lcd. It could also be the back light bulbs.

If you don't see an image with the flash light, then it could be the main logic board.

E500 won't shut down


It is probably not shutting down because there is a program running that will not shut down. Unnstall programs you no longer use and do a virus scan, often the programs that refuse to shut down are malicious. Holding down the power button for 5 seconds should shut down the computer (it signals the motherboard to power down). As for the black screen, not enough detail for me to say.

Monitor problem


You are experiencing an inverter board failure. You will need to replace or repair the inverter. The inverter drives the CCFL lamps that illuminate the screen if the lamps draw to much current or components on the board are overheating it will shut down the backlights. Some monitors have cold solder joints on the toroidal coils of the inverter that causes this problem, very typical with HP monitors, If you are handy with a solder iron you may try just re-soldering board and replacing push-pull transistors for a few more years of use. Provide make and model and I can be more specific about probable cause and solution.
