I had recently done a clean image from backup and decided to install the latest Intel Integrated graphics driver for my R61, not from the Lenovo website but the Intel site. This was apparently a bad idea as I started getting wierdo errors when I would change power sources, ie. AC or Battery. I thought it was the Power manager so I installed the latest from the Energy Star compliance link in the Lenovo download section, but that did not solve it either. So I did a clean install and went piece by piece into the setup and almost as soon as I installed the latest(14.33.1 package) from Intel this started happening. I uninstalled the latest and greatest from Intel, went back to the Lenovo downloads and redownloaded the "suggested" package and all was fine.
It seems this is one of a couple issues with this version and thought I might post to 1.) ask if anyone else noticed anything and 2.) help inform the general population.
