My laptop won't turn off even when I hold down the power button. What should I do?

[kirbychan234]

The keyboard suddenly stopped working, so I went to restart it. The computer started updating, and then once it finished the updates, it never turned off. Right now it's just stuck on a black screen. I've tried holding down the power button for at least a minute but it still won't turn off. I have no idea what I should do now. Please help!

You may have to wait for it to drain of power, or pull the battery if it isn't under warranty and you can open it up.

Once done, try the following...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

Once you can see the display (if you can) on the external monitor, then you can determine what the problem is.
