Hardware question: How big a risk of heat damage would I be taking by leaving my laptop in a car that's parked outside, in the shade, in ~85 degree (F) weather for a week+?

I know that the car will get much hotter than the outside temperature. On the other hand, that's still much cooler than the running temperature of a laptop under load. On the third hand, the heat under load is concentrated in areas that are designed for it; I'm not sure how other components would do.

Anyone have thoughts?

@codesections i wouldnt subject electronics to that kind of temperature
@codesections but between this <https://superuser.com/questions/429154/will-hot-weather-break-my-laptop> and what @alexcleac said, if you have to leave a laptop in a car, i'd at least take the battery out
@codesections cool i guess properly-formatted URIs arent being linkified

@codesections I think your battery can degrade if temperature stays high for a long time. For all the other things, I think it will be ok.

@codesections I’d be comfortable leaving it powered off in the trunk in that scenario. The trunk doesn’t get nearly as hot as the cabin.

@djmoch @codesections

trunk, yeah. but if it is well and truly in the shade the whole time (eg, interior of a parking ramp) even the cabin shouldn't get any hotter. any direct sun into the cabin is your killer here

and if 85 is the max, the average will be lower, and better (assuming in this case it's not too enclosed--open sided parking structure)

85 is cooler than body temp.

my concern would be theft tbh

@deejoe @codesections Definitely want it out of sight, whether that means in the trunk or squirreled away in the cabin somewhere curious passers by won’t see it

@djmoch @codesections

a nice instance where one solution meets disparate requirements

@djmoch @codesections

although now a Gollum-like self loathing wells up, hiding My Precious from filthy hobbitses and how the light it burns us

@codesections If you keep is submerged in a bucket of water in the car, it will not only keep the temperature down, it will distribute any excess heat evenly. (Also, it will decrease the desirability for theft)

That must be that "water cooling" thing all the kids are on about! Thanks for the tip :D

@codesections 85°F is less than 30°C and consumer electronics are, conservatively, rated for use in ambient temperatures up to 35°C.

Given that your laptop won't be powered under those conditions you will be fine. If it really bothers you, place it under a front seat where it will be in close contact with the floor and in the coolest part of the car.

@codesections
Be only concerned about battery. As lithium-ion batteries will age (decay) faster when affected by constant heat.
