[All 220-1101 Questions]

Show Suggested Answer Hide Answer
Suggested Answer: A

If a laptop does not charge when connected to a USB 3.1 docking station despite the AC adapter being plugged in, the most likely reason is that the dock is not designed to provide power passthrough. This means that the dock's primary function is connectivity for peripherals rather than power delivery to the laptop. The other options are possible but less likely if the sole issue is the absence of charging functionality when the dock and its power supply are properly connected.

Reference: CompTIA A+ Core 1 (220-1101) materials, which discuss the functionality and specifications of peripheral devices including docking stations.

I'm going with option B. If the dock is only connected to a USB 3.0 port, it might not have enough power to charge the laptop. Gotta make sure it's plugged into a 3.1 port.

Yeah, it's possible that the laptop isn't getting enough power from the dock.

Haha, too many accessories plugged in? The user must be trying to turn their laptop into a full-fledged battlestation. Gotta keep it simple, folks!

I think it's gotta be the drivers. If the proper drivers weren't installed, the dock might not work properly. Better check that first.

I agree with Hortencia. If the dock is not designed for power passthrough, then the laptop won't charge.

The most likely cause is that the dock is not designed to provide power passthrough. I've had issues with that before with some docks.
