Unit won't turn on until heated over a stove for 15 minutes
Last winter, I left my laptop in the car. It was about -10º C (14º F) outside. About 7 hours later I got back to the car and realized that the laptop was still in there. I took into the motel room and let it warm up for a few hours, then tried turning it on. No luck there. I tried a spare battery, but no luck. After pushing the power button repeatedly for 20 minutes, it finally turned on. I felt relieved, but the next day, it wouldn't turn on again. I held it over a hot stove for 15 minutes, pushed the power button repeatedly, and it started. After having to do this a few times, I've just left it on for the past 6 months.
Yesterday, the system froze so I had to turn it off. Of course, back to the same old problem. What could have been affected by the cold temperatures? Bad power button, cracked or intermittent solder joint? I'm an old tech who used to work on telecom equipment, test equipment refurbishing, VCRs, etc., so soldering a board is no big deal, but I'd to know where to start before I open up this baby. Thanks.
Is this a good question?
