When a Switch Lite will not turn on, Nintendo's own advice and the repair guides agree on a short ladder. First, a force restart: hold the power button for at least twelve seconds, because the console can be hung and look dead. Second, charge it: connect the official adapter for at least thirty minutes, because a Lite that was left flat for weeks sometimes needs a long time to show any sign of life, and a full charge takes about three hours.
Third, look at the charging light on the bottom edge: if it does not appear, unplug the adapter from the wall and the console, wait twenty seconds and reconnect both ends. Then check the USB-C port for lint and test a different official adapter and outlet. If none of that brings it back, the battery or the board has probably failed and it needs a repair. If the console has been dropped or exposed to heat, mention that to Nintendo, because those events point at the battery or the board and not at a flat battery.
