I’ve just been fixing one of these tonight if theres no light on the charge wire and you’re sure the charger is good its likely a blown u7000 but its worth changing q7030 and q7031 while you’re here.

I replaced a u7000 tonight the tools I used are a MUSTOOL G1200, 858d hot air ‘station’ max heat and low air, soldering iron with 900m-t-s bent tips, leaded solder and fine tips on my multimeter. I have experience with bits of hot air soldering and its at the limit of my abilities and very easy to create a dry joint.

I appreciate this is a long and complex answer but I’d prefer the information to be here for the next guy so they dont get told to repeatedly reset the smc.
