I have a gaming laptop. I been playing games on it for many months now (got it in July). All games on max settings have been running smoothly for me. Until today. Today I was playing a multiplayer game from 2006. The game is not demanding at all and my computer can easily run it. I never had any problems running this game. I played the game and then exited the game. Afterwards I went to do other stuff on my computer for 2 hours. Then I go to play my game again, but suddenly the game is running at really low FPS rates. It feels as if it is running at 15 FPS rate. In fact, I tried some other Steam games and they all were running slower than usual. I did nothing to my computer. I downloaded nothing. It was just like it always been. Except somehow the games started to run on low FPS rates. I suspect that maybe the low FPS rates is a problem from the Steam servers, but as I only have Steam games on my computer I cannot check how non-Steam games run on my computer. I have no idea what this is. I figure that I should look for any changes in the computer. My computer seems to give me the following message every time I turn it on, " the AC adapter cannot be found, the battery may not charge". I never had this before. When I shut down the computer and turn it on I get this first message before Windows 7 loads. When I look at battery it says "85% avaliable, not charging". It seems that the computer is not charging my battery. Other than that all seems exactly as it was. Maybe this is irrelevant to my question, but I bring up anything that is suspect. Perhaps, the computer does not fully recognize the AC adapter and so it is operating on low resources - hence the low FPS rate. (Yes, I did at one point in those 2 hours unplug the power supply from my computer). What should I do? (By the way. Please do not tell me to run virus tests. I know it is standard on this forum for members to tell others to run a virus test, but I know for a fact my computer is clean. I go to secure websites all the time and always am up to date with my anti-virus program. I know that cannot possibly be a reason. Furthermore, in that 2 hour interval I only been using secure safe websites, such as Gmail, so I know I could have not possibly picked up a virus. I just say this because I really do not want to run all these anti-virus tests, and downloading them, for several hours only to show that I was clean all along).
