The Dell Latitude 3190 was an improved release of the 3189, with a quad core Pentium processor, produced primarily for K12 applications.

In the coming days I will populate this page with simple fixes to the most common issues I have experienced. This page is a work in progress, started June 14th, 2021.

  • Not powering on, or appears to not charge
    • (Internal MB cable loose, will add pics)
  • Left hinge failure, the brass heatserts break out of the chassis. Preventative measures best, if it gets wiggly then tighten the screws.
  • SSD is serviceable
  • Wireless NIC failure is not serviceable
  • Intel SSDs are notorious for failure
  • M.2 is SATA only
  • Keyboard model, cheap to replace.
  • Audio daughter board separate module, can be replaced if broken
  • LCD assembly kit link
  • Track pad ribbon cable not seated properly
  • How to determine if it is the charger or battery, battery communication in BIOS
  • HP chargers will likely not work, must use Dell branded chargers. Use knockoffs at your own peril.
  • DC socket insulating barrel will disappear in a 2018 production batch. VERY common. If this happens, the socket can short out and (I presume) damage the charging circuit. Replacing the socket itself will not fix this.
  • All parts except the audio daughter board are interchangeable with the 3189. You can still make the daughter board work, though.
