Oh no, it just happened to me as well…
On 16/12/2019 I received an e-mail sent by chuwi to everybody via the indiegogo platform with subject “Update #26 from MiniBook-Mobile Workstation In Your Hand”.
In this email they published a small FAQ and all the download links to the firmware and bios download files.
In the email FAQ they did explicitly write:
“Q4: The cooling fan is too noisy.
A4: Reinstall the BIOS”
Since the annoying fan on my unit was constantly on today I flashed as instructed the right BIOS and EC files for my N4100 minibook.
And now the laptop turns on to a black screen, no chuwi logo anymore, just the led and the keyboard backlight light up.
What could I do? I’m desperate!
