Hi, seems like a common issue accross the board with no real resolution, I have a Lenovo L430 which I purchased recently, I installed 64-bit Ubuntu 12.04 with kernal 184.108.40.206-generic, with unity desktop and im getting system freezes a few times a day, I have to do a hard reset (hold power button down) to reset my machine, the mouse pointer freezes and the laptop is completely unresponsive.
The action I've taken so far:
1. Removed Unity desktop, replaced with Xfce
2. Replaced Open Java with Sun
I however still got a freeze, very annoying.
I know allot of people are experiencing these issues at the moment, and upgrading to 3.4 kernal seems to be an option, however im a bit reluctant in case it makes matters worse as I use the latop for work and cant afford to have a load more crashes during my work day.
