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.
I'm not a fan of Unity, Compiz and, or Ubuntu fanfare, but I first test
ran Ubuntu 11.10 "Oneiric" beta2 from a USB Stick for about 3-4 hours on
a DELL Inspiron N5010 and then installed a proper release on this laptop
a few days ago for my nephew as dual boot alongside original Win7 which
I did not want to remove due to a simple reason that this laptop is
still under warranty till November 14, 2011. FYI, the machine runs fine
here even while booted off of a Ubuntu partition :)
I have not read, but still hope that the page at

<http://tldp.org/HOWTO/VAIO+Linux.html> helps solve your problem.
