My girlfriend has the same problem when she uses her laptop. She says her laptop gets hot when she uses it while sitting on the sofa in the living room.

Sounds like your girlfriend is blocking off the airports on the underside of her laptop. Sit the thing on a hard flat surface like a book or lapdesk. Setting the laptop ontop of a pillow, or anything else that will choke off the airflow, and pretty soon that sucker will just die.

microphone cable? they must be the very very cheap thin wires. Or very very sloppy soldering work. thought only CPUs, graphics chips, batteries burn up.
Ok, blame it on global warming.

wow, are you LISTENING DELL AND NVIDIA!! (disgruntled owner of a m1330 with a 8400gs that is presumably made out of mercury!)

What......do you intend to eat your gpu?

The mic cable carry very low voltage and current, a short cannot overheat anything, I guess Acer want to hide the real cause of recall, perhaps is something heavier...

mihaicozac: +1, the voltage carried by the mic line is equivalent to how much electricity the sound in the room can generate by moving the mic diaphragm, since the mic amp is surely on the motherboard, and the post-amp "wires" would be non-replaceable copper embedded in the PCB.

there must be two wires form the mic: one for the mic signal and a ground.

My guess is that it's the ground that is to blame. Repeatedly applying pressure on the ground wire can skin the wire and make a short with a more current demanding live part of the laptop (battery?)

oh and some mics work on 5VDC polarization.

Can't resist this: I get hot, too, on my girlfriend's lap sitting on the sofa in the living room. Can't blame the computer.
