Default Acer Aspire 5672WLMi fails to power up

This laptop was used with the wrong AC adapter. Original AC adapter is lost. I tried powering up with bench PSU with 19 V DC but it was no go. The laptop was drawing something around .20 amps when I pressed the power reset which is obviously not enough to get anything going, no lights, no sound - no nothing.

On eBay I've seen the power jack and cable that plugs into the main board sold as a unit. Is it possible this jack & harness assembly has a power fuse included which may have burned out when a wrong AC adapter was used?

Any suggestions on how to trace the burned out components? Possibly the power regulation section of the main board, somewhere underneath the power-jack. I received one helpful tip to look for burned out diodes in this area.

Anyone with information on the strip-down sequence of the main board, in case I buy a refurbished replacement board.

Thank you for your comments in advance.
