[wplug-erie] dual boot laptop over heating

In my experience with laptops, they will "overheat" basically because of how
the are designed. Between the laptop charging all the time ( I assume
because he's using it multiple hours at a time so it needs to plug in) and,
small fans to cool hot processors, it just seems inevitable. Every laptop
I've ever owned becomes very hot after hours of constant use no matter the
OS. On the other hand you don't say if its getting hotter when running
Linux vs MS, though I'm assuming it is because your question seems to imply
that there is a different in OS's. To be honest though I'd look at the
battery power management for Linux if it's gettting hotter than Windows.
The IBM may not have as efficient driver for battery charging and isn't
"trickleing" the lithium battery correctly. I'm only guessing to look there
because I'm assuming again that the battery module is towards the front of
the laptop and that is where the excessive heating is. Basically when the
battery is discharging it's producing heat and the Linux kernel may not be
telling the computer to ignore battery and just use the inline power so it
keeps discharging and charging the battery constantly. All in all though,
if it's not causing either OS to lock up and neither OS is saying there is
something massively wrong, it just let it be and get a laptop cooler to help
keep it cool.
Good Luck,
Just Bill
