Windows 10: Lenovo IdeaPad S340: Screen flickering/blinking when charger plugged in.

Hi everyone, i was wondering if you could help me regarding the above. Whenever i plug the charger into my laptop the screen goes absolutely crazy and blinks out, goes black, blinks again. I've tried to change the refresh rate from 60 hertz down to 50 but the only option is 60.

Can anyone recommend the best thing to do here? Need this sorted ASAP for Uni.

Flickering and blinking laptop screen

I'm using a laptop with Windows 10 and an Intel HD Graphics 4600 display adaptor. A few days ago I attached a Dell D3000 dock to my laptop, and almost immediately my laptop screen started to flicker and repeatedly blink off and on again. I disconnected the dock, which did not resolve the problem, and since then I've tried various techniques to fix the problem, but none of them have worked. In order, this comprised of:

1. attempting system restore - but all five restore points were corrupted (?!);
2. updating the driver for the Intel display adaptor;
3. rolling back the driver for the Intel display adaptor;
4. uninstalling the driver for the Intel display adaptor;
5. downloading Windows 10 from the Microsoft site and re-installing it.

The problem has persisted even when I disconnected everything from my laptop, took it to my workplace, and switched it on there (using its battery for power); so the following possible reasons can be ruled out: its location in my house, any attached peripherals, a faulty power cable.

I am certain the problem is in some way connected to the Intel HD Graphics 4600 display adaptor:

1. after I completely uninstalled it - which reverted the graphics card to the standard Microsoft one - the screen didn't flicker or blink once afterwards (I left the laptop switched on for about an hour without incident, whereas previously I would experience as many as ten 'events' a minute). This rules out a possible damaged connection between the body of the laptop and its screen. However, when Windows auto-installs updates it reinstates the Intel one...
2. ...and when the laptop is switched on the screen flickers and repeatedly blinks off and on again...
3. ...although, strangely, connecting an external monitor to the laptop (HDMI to HDMI) results in neither the laptop screen nor the external monitor flickering or blinking. The problem returns when I disconnect the HDMI cable from the HDMI port on the laptop.

I now have the inescapable feeling that when I attached the dock I somehow fried the Intel display adaptor, and it isn't possible to fix it: I have read in the forums that replacing the graphics card on a laptop is well-nigh impossible. But if anyone else can suggest an approach I haven't yet tried I'd be very receptive!

As an aside, I contacted the retailer and they have sent me all of the drivers that are available for my system, but I don't know how to install them.
