fan

Just bought an HP 4530s from newegg. Laptop is great, but..

The FAN is always on. I did some googling, found it is a known problem, but no easily googlable solution.

Tried to:

Update BIOS to the latest
Disable "CPU fan always on when plugged in" BIOS setting
Installed Windows 7 Home (came with), Live CDed Ubuntu, Windows XP
Spent 2 hours with horrible HP support
Some other things that I can't already recall => spent too much time on it

Laptop is not refundable (learned it the hard way, after the fact, by looking at the NEWEGG clever policy that is hidden in "details")

I would really appreciate a workable solution / workaround / hack. The laptop is for my friend who will most likely be running Windows XP/7.

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More

It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't… >>> More
