G505s: System becomes very slow when plugged in the power adapter

Question

I have a problem with my G505s. Whenever I plug it in to charge, the PC slows down very much. Apps take a long time to open, Youtube videos take a long time to load and games which I have downloaded lag a lot even on low settings. 

 

I noticed this when I was playing a game; the settings I had were 'Ultra' in which there was no lag but when I plugged in the charger the game was completely unplayable. I switched the settings down to 'low' but there was still a considerable amount  of lag. 

 

The laptop has a short battery life already and hardly being able to use it while charging.

 

How can I fix this?

Answer

If you notice the battery charging slowly, please try to update your BIOS to version 2.05 or above from the link below

I purchased model g50-70 model about 6 months ago.  In the last few days, the battery sometimes charges and more  times it doesn't.  Can't tell if it's the battery or the ac adapter.
