Hi all,

I've just been having a weird problem. The contrast was low, I
thought it was badly set and then I handled the Newton and it was
very hot on the back, under the CPU/SER Board (under the top card,
right side if you look at the screen).

I removed both cards (the top card was a linear card and the bottom
card an ethernet card), they were both cold. Then I reinserted the
linear card so it could deactivate the programs, I unplugged the
Newton (power and serial cable), removed the battery and open the
case, a couple of minutes after I noticed it was hot).

The CPU was cold, so was the voyager.
The SER Board was a little bit hot, just like the case just where the
board was.

The chips under the board were cold or just a very little bit hot.

Anyone got this problem?
Could it be SER Board related? (the weird thing is that there is no
chip on this side of the board).

Could engineer specialists tell me what they think about it?

Anyway, things are back to normal now, but I am quite scared and I
hope it won't happen again some time at night or when I'm away from
my Newton.

Paul
