My computer still functioning even its shutdown already

When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.

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

Thank for contacting Fixya, I will be glad to assist you.

Here are some steps you can try to resolve the issue:
• First, hold in your power button for approximately 10 seconds to do a hard shutdown.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the startup sound for the third time.

• Release the keys and allow the Mac to start up.

If neither of these processes do not work, have your RAM memory checked, as this could be a factor in your G4 not booting up.

One other factor to consider, especially given consideration of the flashing light and no boot up, depending on the type of G4 mac you have, would be the power supply, which is what gives your G4 the power to boot up and function.

Hope this helps.

Old computer technicians trick. 1st, remove the battery and unplug from any power. Hold the power button down for about 10 seconds to short the board and clear any charge left in the capacitors. Plug in power supply and press the power button. It should boot up fine and you can put the battery back in.

try to reset it by removing the batery and the power cord an pressing for 30 sec the power button; if is not working maibe you have la faulty LCD inverter and msut be changed.

check your video card ...or try a diffrent montor

Sounds like a classic case of hardware failure!!!!!!! possibly your motherboard, start by removing the battery, hard drive and optical drive.
disconnect the laptop monitor and connect the laptop to an external monitor.
remove the memory modules clean the brass contacts with a eraser and place back in the machine 1 at a time to check to see if they work, remember to plug in the AC power suppy, if you see the post screen then its a memory issue and you can then reconnect your laptop monitor to see if it lights up, if everything works but the monitor then its the inverter or backlight that has blown and is easily repairable saving you money on a brand new screen

oh no please stop,you do know that Fn-F1 puts the eeepc into sleep mode and Fn-F5 switches from internal to external monitor ,its very easy to hit these hotkeys accidently,im sorry i couldnt have told you this earlier
