My thunderbolt 3 (135watt) dock will not charge my T580 intel core i7-8650 laptop while displaying on 2 monitors. Tried only 1 monitor and still won't charge. About 3 months ago first got a message that insufficient power to thunderbolt dock. Warranty replaced the dock last week and still won't work. I took the laptop to work since I have an identical rig and it charges and displays (only 1 monitor but will also charge an iphone). I brought a new 135w charger home and that didnt help. Also replaced little cord from thunderbolt to T580 and that didn't work. I even tried a different outlet on a different circuit and that doesn't help. Could it be that the i7-8650 needs the 230W thunderbolt?
