Updating a Switch Lite's system software needs a Wi-Fi connection and enough battery, and most failures are about one of those two. Start with the battery: the console needs a reasonable charge or to be plugged in, since an update that stops half-way can cause startup trouble. Next the connection: update in System Settings, System, System Update, and if it hangs or fails, run the connection test under Internet, Test Connection, and move closer to the router. If an update downloads slowly, pause other devices.
If the console will not start after a failed update, use Maintenance Mode, which you reach by holding both volume buttons while pressing power, where you can try to update via the internet. Games also update separately: select the game, press plus and choose Software Update. Keep the console on Wi-Fi and plugged in for the update, and if the download keeps failing at the same percentage, change one thing at a time: the router, the position or the time of day. Nintendo's servers are busiest in the first hours after a major game or system release, so a failing update on release day often succeeds the next morning.

- The error code shown
- The Wi-Fi strength and the connection test result
- The battery level
- Whether a game or the system is updating

Model-specific
What is true of this model and not of its siblings
- Do not interrupt
- A half-installed update is the main cause of startup trouble.
- Maintenance Mode
- It includes an option to initialise without deleting saves, but only use it on Nintendo's advice.
- Clock and certificates
- A console with the wrong date can refuse an update because the secure connection fails.
- Never hold power mid-update
- If an update seems stuck, wait at least twenty minutes before holding the power button.
Stop boundary
When this stops being a self-service repair
- !If Maintenance Mode cannot update, contact Nintendo
- !If the console loops after the update, note the code
- !Do not initialise the console without advice
