Non-working Dell AC adapter


Places the dell PA-10 AC Adapter/system board connector right under the right side of the left mouse click button, right where maximum flexing occurs. This eventually breaks a contact of this micro 80 pin connector from the system board and the symptoms are intermittent power on, screen crashes during normal operation, or no power up at all.

First, take the laptop apart.
To do this:
- Remove DVD drive
- Remove Battery
- Remove the keyboard by popping the thin plastic strip above the F-keys and the two screws at the upper edge above the keyboard. Note these are B-4's (Rounded head short). Tip up the keyboard and remove the Dell PA-10 AC Adapter ribbon cable by lifting the ends of the connector to unlock the connector and pulling the ribbon cable out.

- Disconnect the two speaker cables at the top left. One is a 3-pin connector with a blue and white wire and the other is a 2-pin Dell AC Adapter with a red and white wire.
- Disconnect the display connector, a many-pin connector to the right of the speaker cables.
- Remove the two F-4 (Flat-head short) screws from the rear under the connector flip-down flap.
- Remove all screws from the bottom except those holding covers on with one exception: Remove cover with Torox screw and untangle wire inside. Put cover back on when this wire is free. Note that the screw size is marked on the cover at all locations.
- Be sure to remove the screw that is recessed where the DVD drive was removed.
- Gently lift the top cover and remove the mouse ribbon cable from the connector under it.
- Now, remove the top and place it aside
- Remove two screws from the Dell AC Adapter. One is near the top left of the module and the other is near the right edge where the thermistor is. Note the location of this thermistor for reassembly.
