Correct. I am not taking the laptop with me, but Valhalla's comment is good advice if one were to take a device where screening might be necessary.

No need to remove battery. Many have been well below 0* F, including mine. If it makes you feel better, then remove it.




Ive flown many times with laptops/electronics, including Denver. Never an issue off, on, or whatever.

I presume if he's worried about the battery freezing, it presumes he's taking the battery on the plane with him so he can keep it warm (the rest of the laptop stays in the truck).

Security at a lot of airports requires you to power up electronics, to show that you aren't using it to smuggle a bomb inside the device (not saying it makes sense...just what we've experienced at probably 75% of the airports we've been thru over the last 5yrs).

How do you power up a battery pack without the laptop to show that it's an operational piece of electronics?

Remove the battery. Wrap it in a blanket



And that will do what? Is the battery going to generate its own heat? Electric blanket? You'll need a long cord, those airport parking lots are huge.


I went.

Presume away.

Just to clarify...

...yes, I was concerned about battery in cold temperatures while leaving it in the car for a few days. I do not anticipate those temps being sub-zero but there is a chance of it dipping below freezing (32 degrees.)

I do not need nor want to take either the computer nor the battery with me on the plane, hence my asking for opinions.

Methinks it prudent to remove the battery and stash it and the laptop out of sight before arriving at the parking lot. The computer and battery will have a couple of hours to acclimate upon return before needing to turn it back on.

Based on the great comments and discussion, I am not going to worry about leaving the components for a few days in the conditions described.

Many laptops,and other electronics, have "parasitic drain". This means the battery can go dead, even when off. Some laptops, in as little as 10 days. This is why I recommend removing the battery.Just plain logic.

Wrap in blanket laptop and battery (removed). Then allow the laptop and battery to slowly warm up to room temperature. Then charge.

Li can be frozen--not recommended. But charge them when it is -4 F and you have a poor and expensive door stop. You want them to warm up slowly if at all possible.

In that case the whole discussion is silly. Just stash the laptop in the truck and move on with life.

The battery will get cold either way.

Only way you have parasitic loss is if you put it in "sleep" mode rather than turning it off.

Hi,i think the easiest way is to Use your fingers or a lint-free cloth to physically remove any large dust clumps or visible lint. Such debris clogs the laptop's cooling system and causes .
