"HP Spectre Thunderbolt 3" to "4K Monitor Thunderbolt 3 Port with PD 85W" throws Power Surge

[smartaus]

My HP Spectre x360 - 13t-ap000 CTO has 

2 USB 3.1 Type C Gen 2 Thunderbolt 3 (Data up to 40 Gb/s, Power Delivery, DP1.2, HP Sleep and Charge).

My 4K monitor has this 

Thunderbolt 3 x 1 (Power Delivery 85W, DP alt mode, Data)

Thunderbolt 3 x 1 (Power Delivery 15W, DP alt mode, Data)

When I connect the HP Thunderbolt 3 to the 4K Monitor Thunderbolt 3 (PD 85W),  get the below error

Power surge on the USB port

A USB device has malfunctioned and exceeded the power limits of its hub port. 

However, when I connect the HP Thunderbolt 3 to the 4K Monitor Thunderbolt 3 (PD 15W), it works but need the HP charger also connected.

HP laptop Windows and all drivers are upto-date. 

Why is the Power surge issue happens with PD 85W?

Anyone with this problem?

@Praveen196.

Thanks for reaching out. 

Before I posted into this community, I made sure all those suggestions were checked. 

However after your post, I tried the hard reset and can confirm there is no updates to Windows and HP support assistant.

I am using Windows 10 Pro, version 2004.

Can you confirm my HP Spectre x360 Convertible 13-ap0xxx (4CJ13AV) does support Thunderbolt 3 PD 85W?

Is there a Thunderbolt 3 driver to be updated?

I thought Thunderbolt 3 should  negotiate the power with the host to prevent the surge.

I understand your concerns.

Please update the thunderbolt driver and check.

sp98906.exe - Opened up HP Thunderbolt Dock G2 and got message "Device not connected". I don't have this dock.

My 4K monitor - Benq PD3220U

https://www.benq.com/en-us/monitor/designer/pd3220u/specifications.html

My HP laptop - HP Spectre x360 Convertible 13-ap0xxx (4CJ13AV) 

running Windows 10 Pro (64 bit), version 2004 (10.0.19041).

Back to the problem, this 4K monitor (Benq PD3220U) has two Thunderbolt 3 ports - one supporting 85W and another 15W. 

Connecting laptop to monitor 15W port: The laptop connects fine with the 15W port.  Thunderbolt Controller in the laptop has read the monitor and is included as part of the approved devices.  Also I noticed this time , I don't need the laptop charger plugged in. 

Connecting laptop to 85W port: The USB power surge message. Monitor is not deducted. 

Is it possible to get someone in HP to verify whether this laptop Thunderbolt 3 can connect to 85W port in this monitor?
