Nice to meet you, *****!
When does it happen?

Customer Replay

Happened once when I was using an Fn key. I cannot turn it off or on. Nothing can be seen on screen

Do you press only Fn key or combination?

Customer Replay

Fn plus another f key but I am unsure which

Can you give me a model laptop?

Customer Replay

Where can I find it on the case?

Check under the laptop.

Try to use a combination of FN and F4.

Customer Replay

Nothing. No response with power button
I left the computer unplugged and recharged it again no response at all when trying to turn it on.

Please, try to Press Ctrl + Win + Shift + B

Customer Replay

No response. It is difficult to tell if the computer is switched on. Nothing on screen, no noise.

When you are trying to charge it, do you see any light indicators, which it is charging?

Customer Replay

To my great surprise after pressing the start button twice. the computer has started. !!!!

Customer Replay

I ran the battery down and then charged it colour went from red to blue.

Is the screen working now?

Customer Replay

yes. Any idea why?

It might be a glitch from the software side
Please, if it will happen one more time - contact us
Is there anything else I can do for you today?

Customer Replay

but do you think the key combination you suggested did anything?

Yes, it might be the case.
This is a combination to reset the video driver

Customer Replay

Ok thanks very much. I was thinking it was dead and burried.

I'm glad everything works now!
Is there anything else I can do for you today?

Customer Replay

everything was working until I pressed Fn +F9 . The screen went black and nothing worked. thinking about it this was the same key combination I used the last time it stopped working

The solution that had helped you before, didn't work now?

Customer Replay

I have sound but no picture

Have you tried pressing Fn + F9 again?

Customer Replay

good idea! It is working.

Is there anything else I can do for you today?

Customer Replay

why do you think this key combination causes a shutdown?

Because that's what the developers intended)

Customer Replay

ok thanks
