Re: Acer Swift sf314-51-55 doesn't start
Remove the CLR and then connect the adapter. Do you get 25V at the gate of both dc-in fets?Comment

And why Now i dont have anymore the vin at the stepdown?Comment

Re: Acer Swift sf314-51-55 doesn't start
It comes from CLR and not dc jack directly. If you dont have 19V on CLR, you wont get it at stepdown controller. Whether voltage will reach CLR or not, depends on the functioning of charging circuit.Comment

That expectation will meet on the board when charging circuit works. Why not give us measurement of charging IC instead of what you expect or think? That'll perhaps help you. Without measurements our guess is as good as yours.Comment

I already gave you the masure of the charging i you asked meComment

Re: Acer Swift sf314-51-55 doesn't start
it's a common issue with these controllers. Try to pre-tin the pads of the IC and try again. it should help till some extentComment

Re: Acer Swift sf314-51-55 doesn't start
If the IC is new, you have to apply flux on it and put some solder with a irn tip.The solder will stick and pins will shine up. Remove any excess solder with a soldering braid. Now ready to go. Once again apply flux on the pcb pads,align the IC with pcb and then apply heat.It should be properly soldered. Touch up the pins if you doubt any connectivity issues.Comment

You need to be more Patient with the pins. It will work after a while.Comment

Re: Acer Swift sf314-51-55 doesn't start
I solder and resoldered manu Times. I get 2.8-3.8v in the current sensor. I have the same tension on the gate of the Second mosfet (i think the Second) and 0 at the first. I dont understand why i have no 19V in the input of the first mosfet. In add, i am not sure of the bq soldering couse of the problem i described 2some message ago.Comment

Considering your stuggle with even soldering a chip,i'll strongly suggest to take it to some professional. An unproperly soldered chip may take you down to a rabbit hole in diagnosis.Comment

Re: Acer Swift sf314-51-55 doesn't start
The problem is the chip. I'm soldering from 10 yeas now and i never had this kind of problem. I see many other people having trouble in soldering in this period, especially with china chipsComment
