I was trying to diagnose how on earth does this thing drain battery even when plugged in. It's in 5V mode, ffs. Temporarily fixed this by using my thinkpad charger, but I guess I need to get new a brick after all.

If anyone else has charging issues, I used Powersupply and Mission Center in the screenshot.

[frame] Apparently my 100W brick can't do 15V.

Didn't pay much attention to it after finding the thinkpad brick. It negotiated 15V3A, but I assume the frame is never going to pull the whole 3A budget.
