Hi, It has been very since I wanted to ask this question. Most of the time I plan the time I will be in a space, so that five to ten minutes before I leave I can turn the computer off to let it cool down. Do you do the same, or do you slide the computer right after using it to the slide or case? Is there a difference between letting a computer cooling down open on a desk, or cooling down inside a sleeve and/or in a portfolio - and does the latter damage the computter ?? Thank you, kind regards, igmolinav : ) !!!
