Primarily a kernel panic caused by incomplete firmware patching; hardware faults are rare.

Edge cases implicate the M92T36 power-management IC or bad battery cells, usually on units that also displayed blue-screen-of-death prior to purchase.

Hold POWER 3 s → Power Options → Restart

Normal restart (POWER 3 s)

Hold POWER 12 s to force shutdown, then connect official charger and boot again

Forced shutdown (POWER 12 s) then boot on AC

Boot into Recovery Mode (POWER + Volume Up + Volume Down) and choose Update System

Recovery Mode → Update System

If Update System fails, select Initialize Console Without Deleting Save Data option in Recovery Mode

Recovery Mode → Initialize Without Deleting Save Data

Contact Nintendo Support for hardware-level repair or board replacement if software solutions fail

If error persists, contact Nintendo for repair or board-level PMIC replacement

System Error, Please Restart

Error stems from network stack handshake time-outs; new Broadcom Wi-Fi 6E chipset can mis-negotiate WPA-Enterprise networks.

No evidence of defective antenna; mostly firmware/driver layer.

Power-cycle router and console to refresh network connection

Restart router & console

Connect to 5 GHz Wi-Fi network or use mobile hotspot as alternative

Switch to 5 GHz band or mobile hotspot

Configure manual DNS settings to bypass router DNS issues

Manually set DNS 8.8.8.8 / 8.8.4.4 (Settings > Internet > DNS)

Remove existing network connection and reconnect using WPA2 instead of WPA-Enterprise

Forget network → re-add with WPA2 (disable WPA-E)

Connect wired ethernet via USB-C adapter to complete downloads, then wireless should function normally

Use USB-C LAN adapter in dock, download all pending updates, then Wi-Fi works thereafter

Unable to Communicate / Download Failed

The transfer program runs a USB-PD handshake; it looks for Nintendo's 15 V / 2.6 A power profile, absent on many generic chargers.

No evidence of port failure—old Switch charges on other cables, but fails AC check because the handshake flag isn't set.

If debris in the USB-C port blocks the CC pins, the console may never detect any adapter; cleaning the port can solve rare cases.

Update both consoles → Settings → System → System Update, then reopen System Transfer

Plug the Switch 2 official adapter into Switch 1 until the warning disappears, then move it to Switch 2 when its prompt shows

Avoid third-party or phone chargers—they charge but fail Nintendo's PD check; do not rely on the dock's USB-A ports

Reset the adapter & dock: unplug AC brick and dock for 30 s, re-attach, and repeat Step 2

Inspect & clean USB-C port on Switch 1 if it still refuses to detect any adapter; cleaning the port can solve rare cases

Bottleneck is almost always server or router handshake; no widespread NAND or Wi-Fi-chip defects have been confirmed.

Switch 2's Broadcom Wi-Fi 6E card defaults to 6 GHz DFS channels; some routers fall back to 2.4 GHz, throttling speed unless manually pinned to 5 GHz.

Storage performance has tested normal once a stable >25 Mb/s link is present.

Settings → Internet → Connection Status → Frequency "5 GHz"; reconnect if it shows 2.4 GHz

Force 5 GHz

Edit network → DNS Manual → turn IPv6 off; many users report speed jump from 25 Mb/s → 250 Mb/s

Disable IPv6

Unplug router 30 s, hold POWER 12 s on Switch 2, then retry

Power-cycle router & console

Dock the console and run the update via Ethernet

Use USB-C LAN adapter

Network settings → MTU manual 1500; some ISPs throttle default 1400

Change MTU to 1500
