what should be the voltage?...

Model: GM501GS

Maintenance Summary:



The device could not be powered on, and the second MOSFET did not pass the 19V voltage. After replacing the charging IC, the 19V voltage passed normally.

The 3V and 5V power supplies were overheating. So I decided to replace the 3V and 5V power supplies, but the problem persisted. Later I found that the EC chip was the problem. After replacing the EC chip, the device worked normally.

After observation, it was found that the battery could not hold a charge and the device would automatically shut...
