I have a Pavillion dm4 Notebook PC Windows 7 Home Premium. Yesterday, I unplugged it from its charger with a 100% charge. I was down to 10% charge in about 2 hrs 15 mins. I have read that leaving my computer plugged into the charger will shorten battery life. Is this true? What can I do to extend the battery life?
I never heard of calibrating my battery until today. I just installed HP Battery Check. It tells me that I need to calibrate my battery, with a message to “Check here to learn how to calibrate your battery.” When I click “here”, I get a pop-up that says “XM|HPSF has stopped working” and “Windows is checking for a solution to the problem…” That’s it. No solution appears. How do I calibrate my battery?

This document provides the info on how to calibrate the battery with a W7 operating system.
Leaving your notebook constantly plugged into ac power will shorten the life of the battery.
Please see this document for battery care tips.
Personally, if my notebook has been plugged in for nearly two weeks, I just unplug the notebook from the A/C adapter and run the notebook on battery power until I get the notification of low battery power and to connect to ac power.
