Lenovo E15 1.Gen no power on, charging IC burning.

[jacobtc]

I have this E15 that had a broken USB C port. Removed the port, and tried powering on the system with the battery connected, the charging IC (SYX198BQNC) becomes really hot (see pic). Can't really find any shorts on the board though, which I find weird.

The IC became hot with the charger connected without battery as well.

What is the first thing I should check?

SYX198BQNC is not a charging IC.

SYX198BQNC is not a charging IC.

Sorry, you are right, it seems to be a IC which has PWM, Upper Gate and Lower Gate in a single package.

Hello,
