Currently trying to figure out an issue with this Dell Inspiron 4000 Laptop.
When I turn the system on docked, there is no display shown, and the LED's on the docking station and Laptop both come on as if it were normally booting but the monitor never displays anything (and I have tried using Fn + F8 to change display mode) but after 1 minute or so the computer just shuts off. And it doesn't get any farther then that when docked.
Take it out of the docking station press power and it boots right up, flawlessly.
(Just a note.... the battery that's in my laptop is dead, and i just use direct AC Power, put it in the back of my docking station if i need to use it, or switch it to just the AC on the laptop itself if i want to boot without the docking station)
I read that the latest BIOS update (which I already did) fixes this issue:
14. Fixed intermittent issue in which the system may fail to complete
POST with AC power attached and a fully discharged battery installed.
Which i hoped would solve my problem, but unfortunately it didn't.
I've searched the web posted on dell forum and have not had any solutions yet.
Some say to delete the docking profile, or maybe you have incorrect drivers.... but i don't see those being the issue since it's not even getting to Windows at all, does stay on for more than 45 secs to 1 minute.
--- Here's the next weird thing:
If I leave the computer off for a few days, then put it in the docking station and boot it up, sometimes it'll start up fine and i can use it with no problems until I shut it down again.
(Just another note, thought "Maybe it's a cooling issue" fan is still spinning and i feel it pushign the hot air out the side)
PLEASE HELP, I'd like to be able to dock my laptop.
ONE MORE THING ...... I have tried two different docking stations.... just in case one was bad.
