Well, I think that's a separate issue. What I was talking about was a design question. In my experience, most mobile phones and tablets won't run off external power unless there's also a battery inserted. The Pinebook Pro is no different in that respect. It is different, though, in that you can run it without battery by wiring up the by-pass cable, which is well documented on their wiki. The Purim Librem-5 can run off external power without a battery. It's part of the dance you need to dance if the battery's been too far discharged to boot, because you need a running system to charge the battery. But I *think* the modem will work only if the battery's in place. I'm now curious whether Chromebooks can run battery-less — but running without battery is such an unusual occurrence that it's probably not well documented for consumer devices. The power setup for the Pinephone(Pro) keyboard enclosure (with built-in extra battery) was a bit dodgy, I'll admit. Mine just died, even though I took the precaution of taping up the Pinephone's USB-C port, so I couldn't accidentally plug in a USB-C power source while it was running inside the keyboard enclosure. (The design was such that you could provide power only through the keyboard's USB-C charging port.) But I've never had power problems with either my Pinephone or Pinephone Pro, over a few years of use. That's just an experiential datapoint. I'm curious under what conditions Yifei had his meltdowns. > My experience of Thinkpads has been a long history of them not melting. Yeah, the Thinkpads are classic solid machines — though I have no experience with the newer models. — Smiles, Les. _______________________________________________ luv-main mailing list -- [email protected] To unsubscribe send an email to [email protected]
