Dell 7390 2 in 1 warning "Slow Charger"

[dqtech]

I have try with 3 different adapter

Dell adapter 40w - warning "Slow Charger" (charge rate 8mW)
Dell adapter 65w - warning "Slow Charger" (charge rate 8mW)
Power Supply Connected with BY-3200 (in bios detect 65w) - okay and no warning (charge rate 25000mW-32000mW)

i already tried update bios and update all driver but problem still persist....any idea to solve this?

With dell 65W charger being used, adapter is detected in bios??. Since you have not mentioned the mb markings, locate the sio markings and check ps_id pin on sio. Is the ps_id voltage reaching sio?
