Finally got back to my ship, after returning from leave to find the P52 back having had a motherboard swap. Interestingly it was still at BIOS version 1.04. Decided to continue in Windows until I had the time and motivation to look at downloading and installing the new BIOS V1.17, but then yesterday it automatically did it, so I'm looking forward to getting things the way I want them now :-)
Anyway, this is really just a warning that just because your system has had a motherboard swap, does NOT mean it has had the BIOS updated to the latest one whilst at Lenovo - even though, given whats happened, that would be the sensible thing to do...

Took my P52 to local support in my country. According to them, waiting for a replacement part. They didn't mention to me what spare part they are going to replace...

There is another BIOS version (1.18): (Fix) Fixed an issue where the system will black screen in OS environment. I have installed it, but did not change anything in the bios....

I have updated P52 to latest 1.18 BIOS and have successfully changed display from hybrid to discrete without bricking the devices. Machine is now up to date with all drivers from System update tool. However when booting the laptop while connected to Lenovo Thunderbolt 3 Workstation dock the laptop will restart or power up to a Black screen initially and hang there for about 45 seconds before the Lenovo splash screen appears then Windows 10 loads. If I disconnect the dock the machine boots up to splash screen immediately. I have the most up to date dock firmware (V1.50_0921) and driver (thinkpad_thunderbolt3_dock_gen2_and_workstation_dock_driver_v10011) installed. If i change the display setting back to hybrid the restarts and power ups return to normal speed, no 45 second delay. Am I missing something?

I received my P52 laptop with 128 GB RAM on 20 Dec. On 19 Dec BIOS 1.18 update was released.
So the BIOS was updated to 1.18, support for Thunderbolt enabled, switched to Discrete graphics,
BIOS boot diagnostics on, Virtualization support on.
Today Fedora 29 Workstation was installed.
Seems not to brick, finally... (otherwise I would use my right as a customer to send a BrickPad back to Lenovo for full refund).
Lenovo deifinetely has to apologize before all frustrated customers...
Hope to be satisfied with this purchase...
Thank you, the Community, for sharing this severe issue. Sad for those who experienced it
Happy New Year!
