This is about the closed topic: 

https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Can-t-charge-phone-over-USB-C/...

 

I found a solution about "the phone shows the charging animation over and over, indicating it's constantly getting connected and disconnected. It does not show up on my laptop either as a connected device." from that forum

 

My laptop have USB 3.0 type A + Charging Port, USB 3.0 type C + Charging Port and Thunderbolt 3 Port. Thunderbolt 3 Port was the problem with my S21.

I fixed by the following:

1. Update firmware/bios with HP Notebook System BIOS Update (Intel Processors) in "BIOS-System Firmware"

2. Make sure you have Intel Thunderbolt Controller Driver installed in "Driver Controller"

3. Install Intel Thunderbolt Firmware Package in "Software-Solutions"

 

Intel Thunderbolt Firmware Package did the fix, the first try didn't work because I had uninstalled Thunderbolt Software so I had to install the 2. then install 3.

 

This is the second time I fix it because I fixed when I had Windows 10 but over time somehow cannot charge my phone, maybe Windows 11 update reset it
