A little hint borrowed from my photography life...
I put my laptops and AC adapters in grocery store plastic bags, then put them in my carrying bag.
The reason is quite simple... condensation forms on the outside of the plastic bag when I come in from winter cold temperatures. By the time I take my coat off and am ready to use my laptop, any condensation that has formed on the outside of the bag has evaporated, indicating it is OK to take the laptop out of the expensive plastic grocery bag.
All electronic devices are affected, and the life of cameras and laptops can be extended by avoiding moisture INSIDE our precious devices.
I carry ZIPLOCK bags in my cameras bag just in case.
I learned this from taking pictures in ice arenas, then following performers. hockey players etc., to different temps outside the arenas. Great at the T.O. zoo!!
