dell e6510 -Solving Yellow Bang Unknown Device Message after Fresh Windows 7 Install

January 18, 2019 by Leave a Comment

Problem: After installing, you see a “yellow bang or exclamation icon next to UNKNOWN DEVICES CODE 28” under Device Manager

Cause: Most likely an ST Electronics Free Fall Sensor (Dell Detect application for some reason does not detect this error)

Solution:

  • Make sure Windows SP1 is installed
  • Make sure .Net Framework 3.5 is installed
  • Download “ST Electronics Free Sensor” executable – Dell download link is here: ST-MICROELECTRONICS_FREE-FAL_A10_R309372.exe
  • Reboot and the icon will disappear
