Either power supply is faulty or motherboard is fried. You can test power supply wires to motherboard with a voltmeter. Should be 12-13.5 volts. To high or very low voltage is bad and can fry video part of motherboard

My laptop won't start up it turns on but then nothing


Unplug the power, remove the battery and then hold the power button for 30 to 60 seconds. Then reattach the power and attempt a boot.

If it boots, then shutdown, add battery and restart.

The laptop's screen display may remain black when there is a corrupted graphics driver, or a problem with the LCD display's back light. (Try tilting the screen to 30 degrees and see what happens.)

It could possibly be that your outputting to the wrong screen - most laptops have a "Fn" button that can be pressed in conjunction with a little screen on the keyboard to switch to either internal display or external (say F1 or F2).

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

How can i reboot my computer please


Rebooting a computer means, pressing the Reset/Restart button. But if you wish to securely restart it, click Start (Windows XP) and then "ShutDown" button, again click "Restart". There's another option when Windows XP is in Classic mode, once you press the Shutdown button, you'll see a small window showing "Shutdown", you can click the arrow button next to the "Shutdown" and then select "Restart", now click the "Ok" button to restart the system. In Windows Vista and Windows 7, click "Start", if you don't see the "Restart" button, you might be seeing the "Shutdown" button, just next to the "Shutdown" button, there's a small right arrow button, click it and select "Restart". Your system will restart.
Let me know if you need further help.
Good Luck.
Thanks for using FixYa.

Will not power up, no fans, post code or display


when you say you press the reset button you mean the power button right?
I assume you just press it and pc restarts...
instead bootup to as far as you can get then press and hold power button until pc turns off then reboot ..you should now be able to access the point where it says windows was shutdown incorrectly or interrupted options to restart normal or last good config etc..
if it doesnt you may need to reinstall windows
