Dell Studio 1535 A/C power does not work

It powers on using the battery.  When plugged in the battery does not charge and it will not power on using just the AC power. 


I tried changing to a known good AC power adapter from another Dell laptop.  Did not work.   Battery works.

I tried installing a new power plug.  (took apart most of the laptop to get at it).  Did not work.  Battery works.

Can I assume the mother board is OK since the battery power works and they both connect in the same area.

Hi fred64,

We will have to check the status of the adapter in BIOS; if the adapter is not detected properly the system will continue to receive power but will not charge the battery. Please follow the steps mentioned below to check if the adapter is detected properly.

  1. Start the computer by pressing the power button
  2. Press the F2 key 2-3 times
  3. you will now be on the BIOS screen
  4. Under the Main Tab look for the option that says AC Adapter Type
  5. If the Adapter Type says Unknown or None with the adapter plugged in.
  6. Reconnect the adapter to the machine and if the status now shows as Unknown then the AC Adapter needs to be replaced.

Also, I would suggest that you run the diagnostics on the computer after the above steps by following the steps mentioned in the video below and check if there is any issue with the hardware on your system.
