Hi all,

I recently bought a Sony Vaio (VPCSB16FG) laptop which I converted today to
a dual boot setup by installing Ubuntu Oneiric. However, when booted into
Linux, the laptop overheats and the fan noise becomes unbearable, so much so
that I had to shutdown the machine to prevent any potential damage to the
hardware. On logging out to the user selection screen, the fan slows down
but it is still audible. Using Unity 2D instead of 3D seems to help a little
bit though I am yet to extensively test that.

The Windows 7 that came with the laptop has been running absolutely fine for
the past few days, so this does not seem to be a hardware defect. My two
year old Dell Vostro running Ubuntu Natty also has absymal battery
performance (30 minutes after a full charge) so could it be that Linux is
really inferior to Windows when it comes to power management? The Vaio is my
first machine in many years where I did not immediately replace Windows with
a Linux distro and have been able to directly compare the power management
of the two.
