I am working on a Dell Inspiron N4010. It is getting no power at all. This computer came in with this issue. I removed the hard drive and tested it. The hard drive is great. I thought maybe it was the DC jack so I replaced it and it still has no power. I have tested the power adapter on another computer so I know it is working properly. Does anyone have any ideas about what could be causing this issue.

    here my laptop troubleshooting guide, i hope it helps you :
    - remove all external devices
    - if no display - test with an external monitor
    - test if it runs from battery alone, or from AC alone
    - test also with a known good battery !
    ***some laptops have a reset button - if you have one use it!
    - remove battery and AC adaptor, hold power button for 20 sec, connect AC and reboot --> any display ? if NO -->
    - disconnect all disk and cd drives, battery , and other cards and peripherals, leave only 1 ram stick
    - boot -->any display ?
    - if NO remove all ram and reboot --> if NO beeps, mobo or cpu bad ; if it beeps, replace ram stick
    -if you can access the bios battery, remove the battery, AC, and bios battery for a minute to reset the bios
    or test it, it should read 3 V
    *** you can test the disk on another pc, if you like !
