Take out your battery. Disconnect your DCinDC-In and take voltage measurement to make sure that both of your new parts are working correctly. OrOr, you could just leave the DCin conncectedDC-In connected to the unit and take voltage measurements. If you have proper voltage levels coming into the laptops circuit board, then more than likely there is component failure. DoDo a visual inspection for any obvious damage. Not really familiar with Mac stuff, but some computers can have fuses in the power supply area.

If you see a component on the circuit board labeled "F1" or similar that may indicated the presence of a fuse. Make sure you battery is removed and check for continuity across the fuse's terminal if one is present. A low reading on the continuity or resistance (ohms) settings on your multimeter would possibly indicate that the fuse was OK. A high reading, no change on the multimeter display or infinity symbol would indicate that the fuse has done it's job and gone "open circuit" or put another way, there is no continuity through the device any longer.

This is an outline of the basic checks to be made at the beginning of trying to troubleshoot a device.
