XPS 13 L322x: How to Increase Charging Speed & Improve Touchpad Register?

Hey guys,

It's been years since last time I used the consumer line, and finally bought this ultrabook. Just have two things (which I know are issues, but were never really discussed for solutions in practical manner) I would like to ask away.

1. Is there a way to improve the charging rate? 14,141whr peak charging speed is way too slow. I was expecting something like 20whr at the least. I know the charging is limited to the 45w ac adapter and the bios, but is there any kind of tweaking I can do to increase the charging rate?

2. Is there a way to make the touchpad register movements/clicks with better accuracy? I never had problems with it moving in opposite directions, etc as indicated in early reviews of the machine. But my problem is that it isn't "sensitive" enough or has issues recognizing the movement for a prolonged time. I maxed out the sensitivity setting which kind of helped me. I know the driver was recently updated and isn't anything perfect, but at the same time would like to know your feedback on whether the rubbery texture is hindering any real accurate micro-recognition for accurate registry.

Love the size and the weight but these two things are quite annoying. I might as well lug around the XFR again.
