May be a stuipd question, but I can't turn on my 830 this morning. It was below 0℃. I'm sure the battery was not empty, as it was around 30% after the commuting yesterday evening.
After arrival in my office, I tried to charge it, but the screen was still totally black, and no beeps. After searching online how to make a hard reboot, I tried holding power button and lap button together for about 10 seconds. Then I heard the beep. Finally I was able to turn on the unit, it showed 18% power left and could be charged then.
So is the temperature a problem? Or the unit should be replaced?
