Re: Lenovo P52 bricked by selecting BIOS thunderbolt support for Linux as suggested in the BIOS help

Maybe they see this problem as "features". I will get my p52 soon, but i just need enable Intel Virtualization.

 

can anyone share experience about update bios through windows? Does it need some config or load default setting in bios beforehand?

 

Due to many complaints, now event update bios would scare me. >…<

Hi hero,

 

You really are a hero - thanks for offering to test those BIOS settings!

I have just received my new P52 and will update the BIOS to the latest version, but still too scared to change those settings and risk bricking it. Let us know when you are streaming!

Thanks

Hi All,

 

I'm in the lenovo repairing center now and just got my "refurbished" p52.

An idea comes to my mind: why not to perform my experiment here?

There you go.

 

1.The mainboard is replaced and updated to bios 1.17 by the technician.

2.Change graphics from hybrid to discrete, restart the computer-> boot and enter win10 sucessfully.

3.Change "Thunderbolt BIOS Assist Mode" to ENABLE and "Support in Pre Boot Enviornment" to ENABLE->boot and enter to win10 sucessfully.

 

Well, hope no more bricked p52 after updating bios to 1.17.

And hope this is my last time to visit to lenovo repairing center.

That's awesome.  Now I look forward to 1.17 coming to the P1 ThinkPad!

I have written the key strokes needed to enable/disable hybrid graphics mode below if you have a black screen but not a bricked motherboard.

 

Note: You may need to spam F1 to get you into the BIOS menu however this may result in the opening of the BIOS instructions help menu which is mapped to F1. To guarantee you start at the main tab of the BIOS menu, I recommend spamming F1 on startup, press esc twice to take you to the restart tab of the BIOS menu and then hit the right arrow once. After performing this, enter the key strokes below.

 

Key strokes:

 

right down down down enter enter down enter F10 enter

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...
