I need to start a personal written-down "brands to avoid" list, so I can put Chuwi on there. I've had two Chuwi devices (a Herobox, and a Minibook), and both have had fundamental flaws that made them an unusable waste of money within about a month.
I still can't believe they released a laptop which:
1. as engineered, can't power on or charge up if the battery is flat, despite the power cable being in,
2. doesn't recognise replacement batteries are installed, so can power on with them but it will never charge them, and
3. when you look for advice on these very issues, it's always "let the battery run down and then it should be fine when you power it on". If you're very clever, you may have spotted a bit of a flaw with that...
