I have CHUWI HiBook 10,1. The problem with this device is, that everything is working (sound, system Windows, USB ports, battery, HDMI) but no display on tablet.

  • There is a little highlight on screen when I power it or power off when logged in Windows,
  • When Windows 10 is loading it dims some screen from bright do delicate light. Same is here but there is no picture,
  • It's not working in any place, in BIOS and in Windows,
  • When I connect through HDMI all is displayed on external monitor,
  • Touch is working,
  • Android on this tablet was deleted. So when I choose option to Android I have error - so it's OK, I don't need Android here,
  • When I connect similar display from other working Chuwi 10.1 tablet, there is the same - a little backlight an do picture. So it seems that LCD is ok. Tablet was not thrown or crashed so it's ok.
  • Checked ribbons, all connected properly. As proof, point above, connecting other screen from other tablet, on different ribbon acts the same, so ribbon seems to be ok.

BIOS Information
BIOS Vendor: American Megatrends

Core Version: 5.011
Project Version: I1D6_C109.224 x64
Build Date and Time: 05/07/2016 22:16:20

BIOS info at bottom: Version 2.17.1249


I have no other info from housing, because there is no info, like SN, model etc. Just blank.

The fact that the system selection menu is displayed on the screen makes it clear that the problem with the tablet is software. You must update the screen driver with the help of the external monitor connected by HDMI. Download the drivers from the download section of this forum and from the device manager, change the driver. The system selection menu can be deleted using the executable that is attached. It is executed, it will ask for confirmation of change to Android, it will be answered no and in the next screen it is chosen to disable the system selection menu.

OK, switch.exe is clear. I can do it later.

Explain me please, where I have to install this driver? I can log to windows usung an external monitor, but this screen is not showing up also when tablet is powered on, so even in BIOS display shw nothing. Also system selection menu is not displayed on tablet. All I see is through HDMI. Screen is backlighted only and when I change brightness in Windows, it dims a backlight too, but no picture. It looks like it's working, but not displaying because it has a bad resolution (too big)? But how it's possible to change this in BIOS?

Installing it in Windows help there too? Or I have to install it in some other way?
Thank you.

I'm sorry, I had not fully understood.
If you do not see anything from the beginning, not even the Bios screen (pressing Esc when booting) is that something is wrong with the screen and, if you say that you have tried with another, the problem may be the flex connection of the board base of the motherboard.
In this case you will need the help of a technician and from here we can not give more support.

As the only option, you could try flashing the Bios in case if it was previously done with a wrong bios, but having no screen I do not know if it will start only the pendrive with the correct bios.
