  • If it’s a relatively recent laptop, it should be fine.

    Many of them will let you set custom charge limits. If yours supports that, limit it to like 60% or thereabouts. Long enough that you can get some UPS use out of it but not full enough it’s ever gonna go spicy pillow on you.

    If it won’t let you set a charge limit, they’ll still kind of float around full charge but not stay at 100% all the time. Even plugged in, mine will drop down from 100% to eventually 92% before it will start charging back to 100 again. That’s over the course of several days to a week.

    If the laptop is older than about 2017 or so, or still has a removable battery, you might want to just take the battery out and use an external UPS as those typically don’t have the extra charge management features newer ones do.

    To run them full time, you either want to remove the screen or “tent” them because a lot of heat is dissipated through the keyboard, and it’s normally expected to be open while running because of that. By “tent”, I mean open it halfway and put the screen facing down so it’s standing up and shaped like a tent.


  • Eh, yes and no.

    A lot of friendships do start out based on proximity, convenience, etc but can grow into something deeper and lasting. Like, many of my friends in school growing up all had last names near mine in the alphabet. Two of those I still hang out with decades later.

    When you leave college and go into the real world on your own, you find out which ones were built on convenience and which were lasting. I couldn’t tell you how many “friends” I had in college, but since graduating, I probably only keep in touch with about 10 of them regularly.

    Reminds me of the saying “Relatives are who you were born into, family is who you choose”.





  • A few years ago I decided to try the lithium-ion UPSs. I’m on my 3rd year with them, and I will never go back to lead acid. I’ve got one “classic” UPS that is still in good shape as long as you don’t try to run more than 100w from it, but when it goes, it goes.

    These use the LiFePO4 batteries, and I get close to twice the runtime as my old ones, and they don’t drop from 80% to 10% like lead acids do. The battery chemistry is also good for about 10 years of daily cycling, so assuming the electronics hold out, they seem like they’ll last.

    The only hiccup with the model I got is it doesn’t have a serial monitor connection, but you can probably fine plenty that have it.
