when new, battery provided over 5 hours of use. Now it only gets 2 hrs with full screen brigthness, and only 2.5 hrs if I reduce brightness to 80%.
Since this is just 11 months old...I think HP should give me a new battery. Will they?
Also...what battery does this use? My system seems to report that it's HT0341XL. Googling produces 2 results HT0341XL and HT03XL Are these batteries BOTH acceptable, and Interchangeable? The HT0341XL is very hard to find and more expensive. Everyone offers the HT03XL
SO there's 2 questions here.....will warranty give a new battery, and which one?

I did the battery calibration, several times now over the course of a couple months. It still runs out of power in 2 to 2.5 hours. The battery is failing....actually has been failing noticeably for months now. AND...you didn't answer my question on part number for replacement....are the 2 part numbers the same, or not???
