X13 AMD USB-C won' t charge with 45W PSU after Power Manager updated

2020-08-31, 11:53 AM

HI everyone, just see anyone have similar issue.


I have got my new X13 Gen1 AMD, when it out of the box, I can use my yoga 910 charger (45w) to charge it, even a normal usb(5v) when power off the laptop.


Howerver, I cannt use any of those lately but factory 65w charger, when I plug in a 45w charger, charging light(next to usb charing port) is on for few sec then turn off. In windows task bar, it wont detected 45W PSU was plug in. I did try differnece  battery profiles still same thing.


It seems start happening since update below.


"Lenovo Power Manager (Windows 10 Version 1703 or Later) - 10 [32,64] -

Successfully installed: 8/7/2020 10:41 AM"


Just curious does anyone have similar problem with other model with same update?

how can I roll this update back?

Dear, basically EC control charge or non-charge, could you follow readme file from web to update your ECFW/BIOS to latest? thank you
