Default [Q] Power tips for the Acer W700

Does anyone have power tips for the Acer W700? I have the screen brightness down. I'm not using the 'power saver' mode because of an issue with Windows 8.1. After installing 8.1 it began to drag. Let me know if there was an update or something that fixed that and I missed it or something. It seems that soon after I'm running the Acer w700, that its down to 75%. So the next thing to look at is some Acer running software. I don't use the 'Acer Ring', but yes I still have it installed. I've heard it uses some good power. Let me know what other things, others have tried, and had success with? Or should I just be thinking of a new battery?

Thankx,

Robert
