Hi everyone. I just got a Dell Latitude 2110,that will NOT POST when the Bottom Base is attached. Without the Base and just AC Adapter no problem,it starts the diagnostic run thru. With the Bottom Base it WILL NOT POST. I know I"m using the correct screws ( 6 only req'd. ) because I have another 2110 to compare. What's up with the screws? Help PLEASE. I need to load OS. Thanking you in advance for any input.
