Hi everybody! 1. Battery Should I take out my battery when I have plugged in AC power supply ? My laptop is always set on Lenovo dynamic graphic, and main task of it, is gaming. 2. Graphic Sometimes when im on "desktop" screen blink once (fast blink) and then Laptop is not reading GTX660M. After blink i must restart laptop to be able for GTX660M GPU use... Is it some kind of issue ? Or just Nvidia/Lenovo drivers are crappy and after turning off dedicaded GPU, drivers can't turn it on again ?

My alienware m18x came with the latest graphic drivers provided by Dell, however, I have an issue with this driver version: stuttering when mouse goes on the upper right corner of a game I play often, 'heroes of newerth' - they say the solution is simple, update to either 10.1 or 11.6 driver version. The problem is that my laptop won't accept any driver but the one provided by dell, I completely uninstalled the dell one and tried to install the one provided by amd, unsuccessfully, since it install but does not work. Anybody have any idea? Thank you.
