Suggestions for keeping your computer warm new
      #6243596 - 12/09/13 08:50 PM

There is one thread over in "Equipment," but I thought I would raise this topic here. Tonight is was 11F. I am in a Pod observatory, no heat. Dell laptop started inside to warm up. First I had camera connection problems. On restart: no restart. Took some time once inside to get the laptop started. Started fine once warmed.

I am thinking a heat pad (a few bucks at a box store) and something like a box to keep the heat in. But I wonder about screen problems. Any suggestions? A thread I should read?

Thanks and clear skies.
Ed

Have you considered a lapdome? If your workflow allows you to zip up the door between uses, it might beat a box.

11 degrees is Brrr chilly!

Thanks for the suggestion, Phyllis. I have something similar and will try it.

11 degrees.....wow, that's pretty warm.

I generally pull the laptops from the observatory when it goes into the teens. If they are warm and they put outside...I never had a problem.

Heating pad plus laptop "dome" seemed to work fine with the pad on high. The only problem with the modern heating pads is the 2 hr automatic shutoff, so you have to pay attention.

Man, I hate those auto-shut offs. There should be a manual shot off for the auto-shut off.

Both my back and my laptop need more than 2 hours of heat...LOL

My laptop stays inside until the very moment I go out to observe; even if my scope sets outside for an hour acclimating. I also keep it covered with an Orion observing hood to hold heat in; a large heavy towel would work too.

I Had a Toshiba laptop. I left it in my observatory with no heat, the screen got a green line going from top to bottom. I got it fix an the same thing happened again. I do believe its because of no heat.

I placed a 25W red light bulb inside my PC that lives in the observatory.
This time of year it often get to -15C here, all I do is switch on the lightbulb for 10 minutes prior to switching on and the HD reports it's temperature between 6C-12C.

I've read that apparently HD's are happy below zero as long as they aren't running, but to run you need to get above 5C.

My laptop generates enough of it's own heat. I use a "tent" made from foam core board. Similar to this one you can buy. http://www.dewbuster.com/dewshield-laptop.html You can buy a foam core board and make one your self. I keep my laptop on an aluminum folding table. With this type of box my laptop stayed warm and the telescope and mount iced before it did under -15 degree temps. Also make sure your not pointing the open end into any wind. That defeats the purpose. William

I believe if you look around you can still get heating pads without automatic shutoff. I just bought a Sunbeam oversized heating pad for my dad for Christmas, at CVS, and it lets you switch from timer to continuous. The way the instructions and advertising are written, continuous mode does not turn off, though I haven't asked Dad yet.

I use a Golden Rod Gun Saver under part of an old car cover.

It puts out just enough safe heat to keep the laptop warm while I control everything from the house using Team Viewer.
