Locked Laptop

[derekpara]

Using Google search with Firefox on my Acer laptop (Windows 10) I clicked on a pop-up label which asked me to continue with Google of Firefox ( I think). Anyway, I clicked 'Google' and immediately the screen went black with the work 'Locking' flashing on screen. The machine then shut down.
Every time I try to start the machine, the power button flashes for a few seconds and then powers off without getting anywhere.

Any help appreciated.

Thanks.

Sorry, Facebook, not Firefox option.

Is it plugged in to the mains or running from its battery?

Sorry again ! ' ..continue with Google or Facebook'.

Battery.

[JimF]

So what happens if you plug it in to the mains?

I think I'm going around the bend, Jim !
Hadn't used the machine for a few weeks and thought it would carry on as it left off; adequately charged.
After charging for a couple of hours it started up ok but is very, very slow. I now takes several minutes to start any programme, whereas it was previously quite fast. Anyway, it wasn't the dreaded ransom scam to unlock I was worried about.

Sorry to have wasted your time, Jim. Have a great Christmas.

Cheers.
