There is two things that bother me at the moment,
Turning on while the charger is plugged in:
It's not possible to turn on the GPD Win while the charger is plugged in,
it will turn off after showing the battery status, no matter how long you hold the power button.
You have to unplug the charger every time you turn it on OR have to restart it.
This is very annoying, especially when doing bigger Windows updates or installing drivers.
Fan turning off when using an external display in single mode:
I also want to use the GPD Win as a mini PC on a big monitor, but when I select the external monitor as a single monitor with the internal display turned off, the fan will turn off as well.
I'd rather want the fan on and running while having the lid closed to prevent overheating..
Is it possible to get these things fixed with a firmware update?
