Hello all, Just got a new XPS L521X with 8 pre installed but the battery life isn't that great. I am getting mixed responses about if this is the normal battery life (about 25% an hour). I put "powercfg /energy" in CMD and I got this back:

Code:

Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled




PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.

Do any of these things really effect battery life and if so how do I go about fixing it?
