Hi

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

AND/OR - Windows Logo key + Ctrl + Shift + B
(This key sequence actually restarts you graphics driver (W10 only).)

AND/OR - If you’re using multiple displays, try projecting video to a different monitor.
Press the Windows Logo key + P, select a display, and then press Enter.

Thanks for the reply but this hasnt done anything.  When it first happened last night I could hear the fan working it was just the screen that wasnt.  Now it just doesnt seem to be working at all.

Hi,

When you attach the ac adapter does the charging led come on? Do any leds blink?

Let me know,

When we connect the charger the charging led comes on as does the power led

You have tried the power reset:

You say that after trying the advice given by @Lil_Boy_Blue there has been a change? Does the fan still come on? Have you tried attaching to externaL MONITOR/TV?

The power button led comes on when you attach ac adapter or when you press the power button?

What is the model or product number of the PC (not serial)

Thanks for the help and apologies as i am not very IT literate.

There was no change at all from the Little Boy Blue advice (apologies for the confusion).

The Charging LED is on orange and the ac led is on as well.

I have tried the video link and followed the instructions with no luck.

The model is: 14-cm0999na
