The ASUS ProArt P16 is built for creators who connect a lot of gear at once, with USB4 and Thunderbolt-class ports, a USB-A port, an HDMI output and a card reader, and the usual trouble is a mismatch between what a device needs and what a port supplies, not a dead port. Start by reading the symbols beside each port: a lightning bolt or a USB4 mark means the fast data and video port, a display mark means it can drive a monitor, and the card reader is separate and needs the card pushed fully home.
The checks in more detail
A color-accurate monitor, an external SSD with a scratch disk for video work or a graphics tablet each have different needs, so decide which job the port must do and check the cable can do it: a charge-only cable carries no data, and a cheap cable fails at high speed. For an external SSD that disconnects during a large transfer, the cause is often power or the cable, not the drive. Connect the laptop's charger, use the cable that came with the drive and avoid hubs while testing.
A tablet or a calibration device that is not recognized often needs the maker's driver; install it from the maker's page and reboot. Check Device Manager for entries marked with a yellow triangle under Universal Serial Bus controllers and uninstall them to let Windows rebuild them. The MyASUS app and ASUS's driver page carry the chipset and USB4 packages, and the BIOS update can change how ports wake after sleep. If a display connected through USB-C flickers or goes black, try the HDMI port to separate a monitor fault from a port fault, and set the display's own input manually.
Creative sessions run long, so power settings matter: in the advanced settings of the power plan, turn off USB selective suspend while you test, because it cuts power to idle ports and drops drives and tablets. The SD card reader can be fussy with older cards, so try another card and clean its contacts with a dry cloth. When a port stays dead with several devices, note which port and the date it began, and contact ASUS with the serial number from the base. Do not use a metal pick in a port, since it can short the contacts.
