This blog entry is a continuation of another series of tests that were run on a HP TX2 in an effort to understand battery depletion trends. This time around, I'm going to explore additional settings to both understand & hopefully improve battery performance. Obviously this is a work in progress, but once completed ... it'll get posted to the front page.

Testing

What's to be gained by collecting data while a laptop operates on battery power? Well for one, we'll hopefully learn some interesting facts about batteries. Perhaps, we'll gain some insight about processors or even subtle differences between kernel schedulers. But mostly, we should be able to predict how long we can park at the wifi coffee shop and surf whilst all the power outlets are unavailable.

It's that time of year again. New laptop to flesh out with Fedora. This time it's a HP dv4-2155dx with integrate GOBI WWAN using Fedora 12. I've got just about everything working except for the multi-format SD card. You got that right, the GOBI works! Read on for full details...

Having finally gotten Fedora 11 running reliably (http://bisque.linuxsoup.com/?q=node/50) on the tx2, now it's time to move to Fedora 12. In short, the news is mostly good. Touch screen, pen/stylus, wifi, ethernet, video & suspend/resume are all working now. Here are my notes on setting up Fedora 12 on a HP tx2 1025dx notebook.
