Prowise 11.6" Chromebook battery not charging

[Waldpiek]

Hello all,

Just got in this Prowise 11.6 inch Touch Pro Line Chromebook.

Problem is that the battery is not charging. Adapter is okay (19 V) and the LED next to the dc-jack is also lit.

Tracing back from the battery connector i found CR8N1 defective.

Does anybody have a schematic for a WIZPIG Ver 4.0 mainboard ?
Or can tell me what kind of mosfet this CR8N1 is ?

Greetings Frans

Here it is...... hard to read but cannot get a better picture,

Top connection i have 18.8 volt, bottom left i have 19.1 volt, and bottom right which goes to the battery connector is 0 Volt.
