Help!
I am trying to repair my Alienware M18r1 AC/DC power adapter. It is currently putting out 34V DC when it is supposed to put out 19.5V. This is preventing the battery from charging because it is triggering the safety protection. It is also causing it to throttle the processor performance. The adapter information is as follows:
Dell P/N: XM3C3
REF. NO.: ADP-330AB B
MODEL: DA330PM111
I believe the problem is with the below pictured regulators. The one with the markings "ZP" I have identified as a Central Semiconductor CMDZ16L but the one located at D136 is burnt so bad I cannot make out the markings. I am trying to locate a schematic for the adapter to confirm this. Any assistance is greatly appreciated.
