Very unique laptop situation

[Jessesau]

For some weird reason my performance in game in terms of fps is better when I'm not charging my laptop at the same time. I run 30 fps with the charger out and 5 fps when I'm actively charging my laptop. Any ideas?

You try taking the battery out when you play on AC power? There could be an inbalance of power somewhere.

Removing the battery when I'm charging does make the performance stay at 30 fps, but I don't wanna have to remove my battery each time, any idea on how I can leave my battery in with it charging and have my performance stick?

Has this always happen, or just recently?

I've never tried hardcore gaming on my laptop before, got myself Just Cause 2 a couple days ago and that's when I noticed this issue.
