I'm having problems with the M200 locking up.
+ the screen locks
+ the hard drive stops spinning
+ power/wifi lights remain ON
+ wifi switch doesnt work
+ sometimes pink/color lines appear on the screen
This happens when I'm playing a game or the laptop is not getting enough ventilation. I've opened the laptop on multiple ocassions, have applied Arctic Silver 5 thermal compound between CPU and heatsink, between GPU and heatsink.
When using a laptop stand with fans, lock ups occur less often.
There is a system fan (NOT the processor fan) which is about 30mm in size and is to the right (or left) of the RAM compartment. It never spins. I have taken it out, connected it to a +12v power source and it spun fine -- it's just that the motherboard never powers it. ACPI detects only one fan.
GPU temp idle: 61C
CPU temp idle: 45C
GPU load: 75C
CPU load: 50C
Crashes occur equally in XP, Vista, and Ubuntu.
