Hello, does your laptop appear to be physically damaged (if it has been struck by lightning). Add a photo if possible.
For a start, you can try this:
1. Disconnect everything
2. Unplug power
3. Push 2-3 times the start button to eliminate remaining current
4. Reconnect everything
5. Push the start button
.
I was watching movies at night before the lighting struck my computer, then I heard thunderstorms so I unplugged everything that was plugged in and while I was trying to sleep that night I saw a bolt of lightning and it went through my plugs... I can't explain more because i didn't see everything.
Unfortunately, I think its probably cooked... you can try going to your local PC repair store once the Coronavirus lockdown has been eased (if this is the case in your region).
