Symptoms

Computer cannot charge when connected U-series monitor to power bank first then connecting the computer.

Affected Platforms:

  • Latitude 5340
  • Latitude 5540
  • Latitude 7340
  • Precision 3580
  • Precision 3581
  • XPS 13 9315 2-in-1

Affected Monitors:

  • Dell U2422HE
  • Dell U4021QW

Cause

The power bank draws a high current spike above 10A after being connected. This triggers the Over Current Protection (OCP) in the monitor.

Resolution

Work-around

  1. Suggest using external power adapter for power bank charging instead of using monitor as power charging source.
  2. If a power bank is with lower power, it could use U-series monitor as charging source for refilling power bank power first. After power bank with full power, the power bank directly connects with the platform for charging it.
