Based on your description, it would seem that your laptop's problem is only the display, more specifically the backlight. Often problems such as these are caused by the inverter circuitry, a long PCB strip that converts the laptop's DC power to a high frequency, high voltage that in turns power the CCF lamp (cold cathode florescent). They are readily available for most brands and models. Probably the most difficult part in thee actual repair would be disassembling the LCD panel display lid and covering to expose the inside. The part number would also be printed on the said PCB.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

How do you remove laptop from lenovo mini dock plus

To remove the ThinkPad, from the ThinkPad Mini Dock Plus Series 3, the user turns the seperate key. The user does not need to remove the cable lock from the ThinkPad Mini Dock Plus Series 3

otherwise I would take it to a local computer shop they may have a spare key laying around or have a trick to opening it.

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

When turning on the monitor the LG logo come on and then a few seconds later ......It goes into low power mode and the screen goes black. Tried everything !

Make sure there is a solid connection between the monitor and the computer. Also, make sure the computer is on. The monitor won't power up completely unless there is a signal going to it. Also, see if the power pack on the monitor's cord is awfully warm. You may have an overheating problem and as a safety the monitor shuts itself off. If it is warm try plugging the monitor into a surge protector or different outlet. Don't use a power adapter that didn't come with the monitor. It may provide too much or too little power. If there is still a problem, contact LG. Hope this helps. Good luck.

I own a lenovo 3000 g400. my problem is that monitor remains completely black when it is turned on,but it seems that its hard drive is working ,as shadows of icons can be seen.


Did you try to adjust the brightness by pressing Fn then the arrow key going to the right, if nothing happens,try to boot you computer to safemode by restarting the computer and then keep on tapping F8 then choose safemode from the list, if its still the same,theres a possibility that there is a problem with the LCD itself and need to be replaced.

Hope this will help...
