It's -5 °C outside and I'm bringing my laptop to school in my bag. I spend a lot of time walking outside in the cold. Then I go into the school where it's 25 °C and fire up the laptop immediately. Note, I'm not using the laptop while outside, it's on "sleep", so the "operating temperature" in the manual is irrelevant I think.
What are the odds that this breaks/wears my laptop eventually, or shortens the battery life? Has this happened to anyone? Any way to protect the laptop without using an additional insulating bag?
Laptop model: Fujitsu-Siemens Amilo Pi-3525
P.S. Some days it snows (high humidity) and some days it doesn't.
