You can unlock a not working charger with a battery drill, using it as a dynamo at the 19 v side. By turning the drill rotary at both side, switched on. The charger has to be ac offline. Works with a single charged laptop cell as well, but not always.

I have a toshiba with this IC, ACOK has 3.0V instead 3.2 or higer, VDDSMB is 3.3V, due a Open drain ACOK Must be 3.3... but I cant to understand what is happend here... may be a bad EC draining too much current from the pull-up? Any tip about this ?
