It's often a faulty transformer

Dirty power and poor wiring are terrible for many things. It's not a surprise it might cause issues with this too.

oh so it's an electronics level failure ? interesting

An Amazon Basics power strip I bought failed and took some of the hardware hooked up to it with it.

What sorts of problems are caused by power supply issues?

zaarn • Feb 18, 2019 • View on HN

Possibly, though I would still check capacitors and any voltage regulation (transformer and linear) to make sure it won't blow up suddenly because some wire coating rotted through.

I'm not him, but probably either shoddy PSUs and/or there were lithium batteries involved. It's the curse of "modern" equipment.

Couldn't it be the charging circuit? Or some fault in the power circuits that draws too much current too quickly? ie it might be something that is easy to replace like the battery, but something that requires a fundamental redesign of the electronics.

It does seem like there's potentially some kind of bad electrical system / lack of grounding issue going on.

Isn't this like 95% fixable with a capacitor ? Aren't there cables with small embedded caps ?
