*snicker* Once again, smart people have failed to properly account for the potential stupidity of the average consumer. I'm sure these things get quite toasty in normal operation (ie. charging + running the chromebook), as does every laptop power brick I've ever used, but only a fracking moron buries it in a pile of pillows, or wraps it in blankets *rolling eyes*

I would be surprised if the 'fix' is anything more than bigger idiot warning labels, and maybe a slightly tweaked thermal cutoff.

I would have to disagree. A consumer product should not be required to be operated in a refrigerated server room. Especially something like a portable chromebook should work fine in a wide variety of situations.

That's not disagreeing. Obviously they DO work in a wide variety of situations and environments, and 99.99% of the time perfectly safely... It is surprising to me that ONLY 9 people found that the charger melted when they left it in a pile of pillows and blankets - while using it to charge the battery + run the computer. Especially since it's a wall wart design.

At full power, these things dissipate ~35w of waste heat (100*.5 - 5.25*3) - only an idiot would take a 35w light bulb and bury it in a pile of pillows, even though it'll work perfectly safely in a 'wide variety of situations'. Can't really blame HP or Google for the idiocy of their customers, even though a bit more thought about how teenagers use their products might have saved them some cash.

35W? You have ~3A @ 5V, so 15W out. Assuming 75% efficiency, that means 20W from the wall, and thus 5W to dissipate while at full load (though that can make a fair bit of heat with something this small). 35W/(35+15)= 30% efficiency...

Didn't they just release these? Not a very good start.
