OverviewFix 1 — Verify PortFix 2 — Update DriversFix 3 — Reset BatteryFix 4 — BIOS Check
The Dell Latitude 7450 USB-C charging fails after a BIOS update or Windows update. The Intel Core Ultra 7 164U platform requires current chipset and Thunderbolt drivers to negotiate USB Power Delivery correctly.

Fix 1 — Confirm Port Supports Power Delivery
The Latitude 7450 has two USB-C Thunderbolt 4 ports on the left side. Both support Power Delivery. If using the right-side USB-C port on some configurations, check the spec sheet as that port may only support data.
Fix 2 — Update USB and Chipset Drivers via Dell Command Update
- Open Dell Command Update application
- Click Check for Updates
- Install all Chipset, Thunderbolt, and USB items listed
- Restart and test USB-C charging again

Fix 3 — Reset the Battery Controller
Shut down the Latitude 7450 completely. Disconnect all cables. Hold the power button for 30 seconds. Reconnect only the USB-C charger and power on. This discharges capacitors and resets the USB-C power controller.
Fix 4 — Check BIOS Power Settings
Restart and press F2 to enter BIOS. Go to Settings → System → Power. Ensure “USB-C Charging” is enabled. Save and exit. Some BIOS updates reset this option to disabled.
