Dell Latitude e6320 charge circuit broken, bypass ?

[Jeroentje]

Hi All

I have a laptop what does not charge anymore, it won't go on without battery.
But even with a "dead" battery it will go on and works fine, aslong there is a battery in. In the dell bios it show no adapter installed, also with a universal adapter same, but does boot, but does not charge and won't go on without battery.

Now I have read: https://www.badcaps.net/forum/showthread.php?t=44259
and it points to PU14 / CD3301 CD3301RHHR_QFN36_6X6 and indeed that chip has some burn marks on pin 34.
According to the schema it should be DC_IN_SS, I could try to replace the whole chip but:

is it also possible to bypass or make a wire to pin 19 (+NBDOCK_DC_IN_SS) ?
so the laptop thinks it is docked (but is powered by adapter plug) and will charge ?

thanks in advance.

CD3301-This should match, rest is irrevalent as they are date codes etc.

maybe a stupid question but if I google on CD3301RHHR I see multple chips but the lower numbers does not match or is that the serial of the chip besides G4 ?

Dell Latitude E6220, The CD3301 is burn, Can I replace with CD3301B or not?

[TECHO TN]

to bypass the CD3301B ic power controller in the dell latitude
1- remove the ic
2- remove the two mosfet pq401 and pq402 then solder to connect between drain and source
3- remove the mosfet pq505 then connect between drain and source also
