won't switch off

[junewear]

My lap top won't turn off. The fan is running the external mouse light is still on. The last thing I did was update then it crashed so I pressed control alt delete to shut down. From there I have a black blank screen!!??

There may be something running then that needs to be done, but the screen is the issue.

Try this...

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.
