I have a samsung NP355V5C with a strange issue...laptop works well fom ac adpater and it works from battery ...But it doesn`t charge...
Battery is brand new...but i have spare ones,it is same issue...
As i could measure everything in charging circuit pu200 is fine,all resistors and transistors are ok,and all conditions are present...pq201 and pq202 transistor gates are not active so regulating is turned off...
I even changed pu200,pq201 and pq202 as well as feedback resistors...same problem...I belive it has to to something with smbus regulating...
What do you think i should try before changing kb9012 ?
to charge the battery affects firmware KB9012. try different firmware KB9012.
