Latitude won't boot without docking station

Hello,
 
I'm wondering if someone could help me out. I've got a latitude D400 and a D/Dock station. My laptop boots correctly while docked but doesn't when it is undocked.
 
So, now I've got a very tiny desktop.
 
Please help !!
 
Thx

    sangwoon,

    Will the system power up at all if it is undocked?  Will the system power up if it is undocked and the AC Adapter is connected to it?

    Hi Steve,

    Thanks for your help!

    Will the system power up at all if it is undocked? 

    No, it won't. The funny thing is that once it is undocked, i can do a re-boot, but if i shut it down and than try to start up it won't power up. Than, I've got to dock it again and do the start-up by pushing the start up button on the docking station.

    Will the system power up if it is undocked and the AC Adapter is connected to it?

    No, this does not work either.

    I've got the feeling that it somewhere a settings issue or so, maybe in the bios, maybe something else but unfortunately I didn't find the solution. I played a little bit with "hot and warm' undocking in the bios settings, but no results.

    Regards,

    Sangwoon,
     
    The problem is apparently the power switch assembly on the laptop itself.  From the information available, that switch appears to be part of the palmrest assembly.  The Dell part number is 4U782.  It can be ordered from Dell Spare Parts or from a 3rd party vendor such as

    Ditto on a bad power button. Those little microswitches can wear out. Aparrently Dell may have noticed this on the older D Series, which is why they switched to keyboard membrane switches on the D820 and 620. They tend to not wear out or break as easily as a microswitch.
