Hey,Does anyone have a saved copy of GX502GW bios v308? I need it to roll back so I can enable undervolting again.Thanks 

Asus advertises that GX502 should be able to charge through USB-C. When I plug in my phone charger (20W) it does nothing. Same with the power bank that I have.Could it be that it is too weak or is it not supported? Do I need some special ASUS charger...
