A:Answer If you expect any battery powered piece of hardware to give you the gaming performance and play time you want for anywhere over an hour, I think your expectations are a little bit high. Ifyou're gaming for 2-3 hours with this laptop unplugged, im thoroughly impressed. IMO While gaming you should always be plugged in.
For other stuff, like word, excel, browsing, and emails - I've had mine survive for a good deal of time on just battery. If you're having power issues I'd suggest adjusting your power profiles to mitigate extraneous power use, reducing brightness, or just finding an outlet.
