Laptop is great in terms of performance but there is either something seriously messed up with the drivers/bios/or the battery. Sitting at the desktop with a clean install of windows and 40% screen brightness, I get roughly an hour and a half of battery life..... That is also with it on the "Power Saver" profile of windows. I have also tried very big undervolts using throttlestop but that does nothing to help battery (Does help thermals, so I am assuming it is drawing less power hinting towards maybe a big bios or software problem...? )
