I had a hilarious experience the other day with an (HP) laptop that I thought might be fun to share here.
I've been getting into astrophotography recently, so I went out to my local Astronomy club's dark site in Middle-Of-Nowhere, Ohio, star tracker, DSLR, lens and nearly brand new HP Gaming Laptop I bought specifically for this purpose in tow.
It was cold as shit outside - 25 with a wind chill of just under 15 degrees. But I came prepared, and the club has a small heated clubhouse on the grounds of the site, so I set up all my equipment, did my polar alignment, and left my laptop plugged into a power outlet and remoted into it on my iPad so I could monitor the data capture from inside where it was warm.
About 20 minutes later, I lost remote access to my laptop suddenly. No problem, I thought. I headed outside to go debug what was going on, to find that the laptop had shut down randomly. That's weird. I tried to turn the laptop on, and it spun on the windows logo for over 5 minutes. I got worried that somehow out of all this gear I brought out to the middle of nowhere in the freezing cold, somehow the laptop was what had died. I try force-resetting a few times, to the point where I get the windows recovery environment, and it boots _so slowly_ that I think something is seriously wrong. Then the CMOS battery reset screen comes up (what the fuck?) and I finally get it to boot after about 8 attempts. However, it's so slow it's completely unusable - the CPU is pegged at the lowest possible frequency and just opening up the controller software for my star tracker takes nearly 5 minutes. decide to pack it in for the night, assuming my laptop is dying.
I bring all my equipment inside to tear it down, and leave the laptop in the warmth for 15 or so minutes while I tear everything else down. Then I hear the familiar Windows 11 startup chime behind me. I turn around and the laptop happily boots up, running at full speed, as if nothing was wrong.
Friends, the laptop got _too cold_. I have never experienced this before in my life, and I have put laptops through similarly extreme conditions in the past for other projects, let alone all the Raspberry Pi's I've left to bake in the sun and freeze in the cold. I am so done with modern technology, I want to return to 2011 when Thinkpads were good, Macbooks were great, and phones couldn't break my brain's dopamine circuits. I'm so tired.
Ha! That's a right of passage, lithium ion batteries state of charge drops to almost 0 when it's below freezing. If you left your phone out with your laptop it'd have the same problem. There's actually special phones you can get that are meant to keep functioning below freezing, usually by means of a battery heater.
I too have done the same thing you experienced.
Now I run everything off of a minipc with a lead acid UPS.
This is also why most of your power packs to run astronomy gear are still lead acid and not lithium. Celestron's not just trying to sell you last generation equipment at a steep mark up, there's a reason for it
