Re: [PLUG] very large laptop

For laptops I've gone with, if it burns your legs, it's too hot. Though I have had my Windows lappie wake up in my bag and get hot to the touch, but it was still running. I think getting something hot enough to damage itself means that it's hot enough to damage you. Most CPUs I've run crazy hot for extended periods of time were fine and continued to work for many months/years without issue. Pretty much comes down to how much fault tolerance you build into your machines. I've run some Xeon L5640s at 180F, which made my office nice and toasty.

Keith,

That sounds REALLY hot.  Got me wondering...

How hot can a laptop get before it's permanently damaged?

I've had the outside case of my MacBook Pro get warm enough
that I wouldn't want it on my lap for long without a lap desk.
Nowhere near hot enough to actually burn me though.
I have no idea how hot it got inside.

I've also left running (sleeping, hopefully) Windows laptops
in sealed neoprene covers inside a backpack in a car sitting
in the sun.  Bad idea?

What's a reasonable max external temp?  Any metrics to offer?

Thanks!
