2 I cannot use my laptop whenever I plug the charger in.

On the Bios screen, go ahead and unplug the power adapter and check if the screen goes blank/black. If the screen dims out gradually, or just goes out altogether, there could be a problem with the FL inverter of the laptop. Type "Control Panel" in the search window, then select Control Panel from the list. I have a user whom has a prblem with her laptop, everytime she undocks it the screen goes blank (I suspect she must have a external monitor connected to the docking station), there is still power to the laptop and the FN + F5 key does not fix the To fix it, I had to go to Power > On Battery > Global Settings > Display Refresh Rate Switching, and set it to Disable. I do not want my laptop to change brightness when my laptop power is plugged in or unplugged. I've checked the power settings and set all of the settings to 'never' but still have i just installed windows 7 and updated to win 10. 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.
