Very good. Personally have not done it with a lab power supply but you can check youtube videos on this topic.

We purchased an expensive tool out of Romania that worked well for the few times we used it.

Often, when you purchase a spare battery - there is some pre-charge on it. Best to have a system that can replenish the charge as required.

this tools is great, i use it, too :o).

I've looked at that after I saw it on Sorin's channel. Would be a nice tool to have, however I can't justify over AUD$600 for how often I would use it. Just too expensive.

I believe I'm in the same boat with the same board and IC, considering taking a leap on a donor board but there's at least one I've come across that most likely has the same issue.

Did this repair ever get closure?

Unfortunately no. I did get a battery and tried to boot the laptop but got a RAM error beep code. I intend to resume working on it soon since a replacement board is not too expensive and I can use it to compare.

Same story as above CYPD4126 is toast on 7415 2 in 1 Service Tag 1PYQPG3. can not charge ,powerup the machine via USB-C.looking into the possibility of installing the DC power jack and drill a hole in the body at its available place ,At the Mb side a blank port is available with DC IN, could solder a compatible female jack on the MB and use optional Dc Jack cable. There is however a blank space for a charge controller IC at the back of the MB. I am wondering if I may need that too? will closely observe the schematics visually to find if the DCIN has any relation to the blank chip space. I have removed the shorted CYPD 4126
