I have a DELL Latitude E7240 hooked up to a DELL PRO02 docking station, with two 21 inch DELL widescreen monitors. And when ever there's a power outage this error message pops up when the system reboots "The battery currently attached to the system will not supply enough power to dock for it to function. Please attach AC power to the dock for it to function normally"
Everything is connected, the AC adapter to the dock. But this happens, i even upgraded the BIOS and nothing happened. I even replaced the dock, still nothing.
This problem is not just with my docking station and my E7240 laptop, this is also happening to three more users in my office. We tried using the Dell Latitude E6230 with the same docking station Pro2x which we used for the E7240 and it works perfectly when there is power outage, no errors displayed after the power kicks in.
But the E7240 displays that error.
Please need more advise then replacing the docking port on the motherboard.
Have you tried updating the E7420 to the latest bios? I have been working with Dell's for years (don't want to say how many :-) but a lot of times they address dock station compatibility issues in their latitude firmware updates. Hope you got this fixed in the mean time!
Those docking stations were purchased for the 6200/6400 series laptops.
The issue seems to be related in changing hardware to reduce weight and power consumption. Part of the weight savings was the battery did not have to be as big so the chemistry of the batteries was changed from Li-Ion to LiPo, because LiPo batteries are thinner and lighter, and less power too.
The newer Li-Po batteries do not need, or have as much power (measured in watts) available as the older systems and the docking station senses the lower power available from the battery, that is what is causing the failure warning.
The reasons that is important is; if we have a power failure, your laptop battery will not have enough power to power the duel monitors the docking station and the laptop, hence the warning.
We will need to purchase a dock for the 7400 series laptops.

It is the problem with Docking port on Laptop's Motherboard, please get this replaced from Dell.
Ensure this docking station is working fine with other E7240 laptops.
