I'm mildly annoyed
in doubt, try fuduntu , which has jupiter already installed.
in some of my earlier tests, I recall:
1. Mint10 run reasonably well on battery..
it is warm compare to win7 ( always cool and battery long lasting)
2. Mint11 cook. 10+ degree more, cannot put on the lap
3. tested with jupiter plus kernel argument to bring down temp, yet it is warm to hot
4. run fuduntu with jupiter, run as cool as ( slightly warmer to) win7.
never tested any Mint12 on this laptop.
