Heat is the #1 killer of portable computers. It's not usually caused by inadequate cooling in the design, but by something over which the designers have little control, obstructed ventilation—whether a portable has resumed from Standby with the lid closed, or a user blocking the vents by placing the machine in their lap or other soft surface, or when someone with a high-performance system fails to blow it out periodically.
Microsoft's decision to allow keyboards and mice to wake systems from Standby by default is a hold over from the days when most machines were desktops, with no lids to open. Pressing a key or moving the mouse was the most practical way to resume then, and accidental resumes were more obvious.
IMHO, when setting the default properties of new hardware, Windows should check if the system has a mobile version of a processor—and if so, set the hardware wake-defaults to NO.
Like so many things in life, the solution's simple. What's difficult is understanding why it's not done that way. :?|
