Re: Lenovo P50 - HDMI not working

2017-03-31, 13:35 PM

Hey Lenovo,

 

the issue regardinh HDMI is far from being "solved"

It's been some time already and it IS still frustating turning on your prime product P50 without knowing if my external monitor will work, and have to do some twiks...

 

some times going into sleep mode and coming back is already enough, sometimes a bios reset...

Installing thunderbolts' divers, or any other driver in a specific way as described in this thread hasn't been truely satifying and we are still waiting for your support

Re: Lenovo P50 - HDMI not working

I have been having issues with the external display not working work on my p50. I finally paid my IT consultant to look into it, he ran a few updates including the Thunderbolt update.  Happy to say it worked for that day after the install and reboot.

 

Then I diconnected and moved locations.  Today I hooked it back up to the monitor... and guess what.. it does not work again... certainly glad I spend the $300 to have my IT guy run the updates for me.

 

is this HDMI issue/solution still on going? or is it concidered closed/solved by the Lenovo support team?

I ended up sending my P-50 in for service a few months ago.  It was not clear exactly what they did (driver updates), but whatever it was the HDMI has been, for the most part, functioning correctly.  There has been a time or two since that I have had it not work and had to reboot the laptop to get it working, but it did come back to life after the reboot.

Re: Lenovo P50 - HDMI not working

I am having the same problem since the beginning, and even updating firmwares as they appear. It works after updating Intel Management Engine or Thunderbolt, then stops again (sometimes after turning off/on the external monitor, sometimes disconnecting the hdmi port, etc...).

Is there a simpler way to restablish hdmi out other than having to force updating the same installed driver and rebooting the machine ?

There is no solution on the link you provided, but just a promess you will fix it:
"""Solution
The external HDMI video is routed through the Intel Alpine Ridge Thunderbolt chipset. A new version of the Thunderbolt chipset will resolve the issue. New chipset firmware will be available on Support Site soon.
"""
Not even a link. Downloading latest thunderbolt drivers doesnt fix the issue. It's been more than 1 year now. What the hell is going on Lenovo ?

Lenovo just posted an updated Thunderbolt 3 NVM firmware on the P50 download page, but did not update the knowledgebase link (https://support.lenovo.com/us/en/solutions/SF16-T0051). The most recent NVM (version 25) is here:

Thanks rboener! I have a user that has had this issue for a while now. I'm going to install the latest firmware for the Alpine Thunderbolt and see how that works out. I'll post an update as soon as I can with the results. Fingers crossed that this works out! :manvery-happy:

So the new Alpine Thunderbolt Firmware worked for me! Had to update the P50's BIOS to the latest version first, restarted the system and then downloaded and installed the Firmware for the link provided by user 'rboerner'. I tested both the HDMI port and Mini DisplayPort, confirmed working with no hangups.

So I installed the new Firmware Rev 25.0 (n1etf08w) to my P50 just for kicks.

 

Here's the Thunderbolt info screen:
