Been running my T-40 for days on AC, battery (high capacity, sticks out
the back) is cool to the touch.

Fan spits out quite a bit of hot air, can't leave my chocolate bars next
to my tp, they melt quite quickly (but the coffee seems to stay warm;)

Feeling the bottom, there's a definite hot spot below the e-r-t keys,
but sharply drops at the battery.

FWIW, HTH
