Top It All said:Since upgrading to Windows 10 from Windows 8.2 I cannot use my laptop whenever I plug the charger in. I used to think that the screen went blank but today I noticed that it dimmed so much it almost was blank but not quite. If I unplug my charger, the screen returns to normal. Is this a setting I can alter or is it a bug? It is very frustrating that I cannot use my laptop if it is connected to the mains.Click to expand...
