Problem
After a recent software update, LAUNCH X-431 PAD VII purchased in February 2025 could no longer charge properly.
When connected to a charger, the tablet detected the power source and displayed that it was charging. However, the battery percentage did not increase. Instead, the battery level continued to decrease until it reached 0%.
I tried several recovery methods
- Holding the Power button for more than 1 minute.
- Holding the Power + Volume Up buttons for more than 1 minute.
- Disconnecting the battery and reconnecting it.
- Charging the removed battery externally until it reached approximately 40%.
- Performing a hard reset of the device.
After the battery was reinstalled, PAD VII could power on normally. However, the charging problem remained.
Solution
The issue was caused by using an incompatible USB Type-C charger.
Although the device may recognize the connected charger and display the charging icon, a standard USB Type-C charger cannot properly charge LAUNCH X431 PAD7.
Use the Original LAUNCH Charger
To charge X-431 PAD VII correctly, always use the original charger supplied with the device.
Do not replace the original charger with a standard USB Type-C charger, even if the connector fits and the tablet indicates that a charger has been connected.
