AC Adapter Checkout (WP z50 - 2608)

AC Adapler Checkout: You are here because the WorkPad z50 fails only when the AC Adapter is used.

•  Battery Pack Checkout
•  Checking Operational Charging
•  Optional Dry Cell Battery Checkout

•  If the power problem occurs only when the cradle is used, replace the cradle.
•  If the power-on indicator for the AC Adapter does not turn on,  check the power cord of the AC Adapter for correct continuity and installation.

1.  Unplug the AC Adapter cable from the WorkPad z50 and measure the output voltage  at the plug of the AC Adapter cable.
    See the following figure:
    
   

   Pin	Voltage (Vdc)
   1	19V (+1.5V, -0V)
   2	Ground (-)

    

   1.  If the voltage is correct, replace the mainboard.
   2.  If the voltage is still incorrect, go to the next step.

2.  Unplug the AC Adapter cable from the ac power outlet and wait 5 minutes  or longer to allow the overvoltage protection circuit or other protection  circuits to be fully discharged and initialized.
3.  Plug the AC Adapter cable into the ac power outlet.
4.  Measure the output voltage of the AC Adapter.
5.  If the voltage is still not correct, replace the AC Adapter
