The dock with LAN port that comes with the Switch OLED Model has no power button, so a dock that seems dead is really a dock that is not powering the console, showing the TV output LED, or charging what you plug into its USB ports. Nintendo's checks are the power chain: the AC adapter, the original HAC-002, must be in the dock's top AC ADAPTER terminal and a wall outlet, the console must be seated, and the dock should light its LED and charge the console. Nintendo's USB article adds that a dock's USB ports charge a Pro Controller, Joy-Con Charging Grip, LAN adapter or GameCube adapter even with no console docked.

Likely causes of “Nintendo Switch OLED dock will not turn on”, and how to tell them apart
- 1
The AC adapter is not in the dock's terminal or is not the licensed one

- 3
A damaged USB charging cable

How to confirm Use the original charging cable (HAC-010) and check it for kinks, cuts or fraying
- 4
A console not seated in the dock
What separates it The LED does not respond after docking because the console is not seated in the dock
How to confirm Position the console so its screen faces the same direction as the dock's front and push it in until it seats
- 5
A dock that needs its firmware updated
What separates it The LAN port dock behaves oddly after a system update
How to confirm Install the latest system update and choose System Settings, System, Update Dock, Begin Update
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the dock's TV output LED flashes once at plug-in
- Whether the console charges when docked
- Which accessory fails to charge in the USB port
- The adapter model number on the bottom where the cord attaches
Try in this order
0 of 8 completedConfirm the connection order
ReversibleOpen the back cover of the dock. The USB-C plug from the AC adapter goes into the top terminal labeled AC ADAPTER and the HDMI cable into the bottom terminal labeled HDMI OUT.
Test the adapter on the console directly
ReversiblePlug the adapter straight into the console to see whether it charges. If it does, the adapter is fine and the dock is the question.
Reset the adapter
ReversibleDisconnect all cables from the dock and leave the AC adapter unplugged from both ends for at least 30 seconds, then plug it into the dock and a wall outlet.
Check the console is seated
ReversiblePosition the console so its screen faces the same direction as the dock's front panel and slide it in. While docked the console screen shuts off, which is normal.
Read the TV output LED
ReversibleWhen the adapter is first plugged into the dock the TV output LED should flash and shut off. While a game shows on the TV it stays solid green.
Test the USB ports
ReversibleThe dock's USB ports charge a Pro Controller or Charging Grip even if the console is not docked. Use the original HAC-010 cable and check it is undamaged; first verify the accessory charges directly on the adapter.
Update the dock
ReversibleWith the latest system update installed, open System Settings, System, Update Dock and choose Begin Update. If it stops, try again.
Request service
ReversibleIf the console still will not charge in the dock or its USB ports fail with a good cable and adapter, the dock needs service through Nintendo's request process.
Model-specific
What is true of this model and not of its siblings
- Dock with LAN port (HEG-007)
- Nintendo's specification: about 4.1 x 6.9 x 2.0 inches and 0.69 lb, with two USB 2.0 ports on the side, a system connector, an AC adapter port, an HDMI port and a wired LAN port.
- Video output
- The dock outputs up to 1080p to a TV; 4K is a Switch 2 dock feature.
- Tools and supplies
- The licensed HAC-002 adapter, the HAC-010 charging cable and a soft cloth. No screwdriver is needed; do not open the dock.
- What to tell Nintendo
- The dock model HEG-007, the LED behavior and the accessory that fails; not a part number.
Stop boundary
When this stops being a self-service repair
- !If the console will not charge in the dock but charges directly on the same adapter, the dock needs service
- !If the USB ports do not charge accessories that charge directly on the adapter, the dock needs service
- !If the dock or adapter is hot, swollen or smells of burning, unplug it
