CHUWI LapBook 12.3. Multiple Issues

CHUWI LapBook 12.3. Multiple Issues.
I have a CHUWI CWI535. Ser No L123 Q64G60170602562

Issues are as follows:
1 The LapBook will not turn on unless the power lead is connected and turned on.
2 Wi-Fi is missing
3 Bluetooth is missing
4 Sound Card is missing
5 USB 3.0 is missing.

The LapBook has been through several COMPLETE re-installs of Windows 10.
I have followed All the advice provided on this, the CHUWI forum, additionally I have followed all the advice given on TECHTablets. I even followed all the instructions on Driver Easy and edited Winsock data.

The LapBook powers on immediately when the external power is on. When the power is then removed the unit will perform ‘Normally’ including a Restart even on exiting BIOS.

I have checked the BIOS and the Wi-Fi seems to be there ?!?!

Similarly with the Sound Card and Bluetooth

The next shot shows the Hidden Devices.

See pictures for Wi-Fi card and USB 3.0 socket.

I am now at a loss. I believe the Wi-Fi and Bluetooth are on the same card, I could understand a loss of the two functions with a faulty card, however to also lose the Sound Card and the USB 3.0 makes me wonder if there may be a BIOS problem
The ONLY thing I have not done is Flash the BIOS.
Any help would be appreciated.
Thank you
