Comment 19 for bug 370173

I can confirm on two different laptops:
After upgrading to jaunty 9.04 they both run overheat even when closed
Acer aspire 5630 with 2.6.28.11-generic | intel core duo 1.66GHz
Acer aspire 5730Z with 2.6.28.11-generic | intel core duo 2.16GHz
both are integrated video

This is definitely an os issue. Both were fine running on gutsy and intrpid.
Both do not overheat when I boot into windows.
