Thunderbolt issues on HP mainly

[kristian buckhoj]

Hey Smart people who might know the answer.

 

I have two issues relate to thunderbolt. The first one;

You see my personal computer is a Lenovo Thinkpad which have thunderbolt. When I bought it. I also got there Thunderbolt dock and it has worked perfectly for years. For some reason, after an update to the firmware by Intel. It keeps disconnecting and then reconnecting like three times in a row every hour. This is really annoying. I can't finde a solution to this and Lenovo says its a intel thing, that they don't have control over. How do I fix this?

 

Now the second issue, the long one;

At my new work i have been given an HP elitebook G5 which also have thunderbolt. This is perfect for the few time i will work from home because i can just use my normal setup, or so i thought. You see at my work. We have usb-c dock and it works perfectly even thought it is connect via the thunderbolt port in the laptop. And yes i have check it is thunderbolt, even the bios says thunderbolt. But when i connects it to my thunderbolt dock at home it will only change and connect usb device. I can't get a display output. I have try to update drivers, didn't work. So i contact HP support which just said, that their device are not compatible with any other accessories then HP accessoires. Which isn't that helpful. So i asked Lenovo which said that their dock use standart Intel firmware for comparability across device. which is true, i have never experience a thunderbolt laptop (including macbooks) not being able to connect and get an display output, except for this HP. In fact I can't even get a display output via HDMI.

What's going on? Any idea to solve this?

Btw i have asked the IT  department at my work and they don't know what's wrong. And yes it also works with the HP thunderbolt dock. We have tested.

 

Hope some knows the answer.

the usual problem with thunderbolt docks is it has to be accepted by the system.. 

is there any thunderbolt driver on your hp.. try running see if it has a setting when you connect that lets you accept it.

I have check all drivers from both HP, Lenovo, and Intel. I have check thunderbolt security in bios, it is set to no security. It works with a HP thunderbolt dock as well as a HP usb-c dock so... I personally at that point actually think HP has lock their laptop to only work with HP dock. At least on their enterprise laptops. But that doesn't explain why i don't get display output via HDMI. If i could just get HDMI to work then it would be fine but.... I running out of ideas.

Same. Other device, expect HP, works on my Lenovo dock perfectly. And since the HP laptop doesn't and only seems to work with the HP dock at my work. I'm expecting the to lock their laptops. But why would they do that?  thanks for the help

to lock customers to hp as vendor.. but if they don't support thunderbolt standards they will loose more than they gain.
