E7240 and docking station

Also experiencing this problem.  Worse, it also throttles the CPU speed down to a fraction of what it runs when the Power is connected directly to the computer and not through the docking station, probably thinking it is battery save mode or something...

Have updated to the latest BIOS, but the problem still exists.

Any other suggestions.

Did you ever get a solution to this error message. I have a few computers giving the same error "The batter currently...".  It seems like a false positive because after pressing F1 the charging works fine.

I am a desktop support person for my company.  We have been using Dell computers for longer than the three years I have been here. We have seen this so far on two E7440s.   "the battery currently attached to the system will not supply enough power to the dock for it to function. Please attach AC power to the dock for it to function normally" The power supply works with the computer but not with the dock and when in BIOS, the power supply isn't recognized.  Doesn't matter what dock or power supply we use.    The first resolution was to open a ticket with  Dell and the motherboard was replaced.   That computer worked fine for about 6 months before getting this error.  I have a new ticket open today for a second computer.  This computer has only been in use for a couple weeks.   Probably going to provide that person another computer and have Dell replace the motherboard on this one.    It's got the latest BIOS.   The failure rate on these brand new computers is not satisfactory.

Just got the E7240 and getting this essage when connecting it to a docking station that worked perfectly well with the older E6 series laptop I had.

I have BIOS A11

Any suggested fixes?  Looking at this forum its been ongoing for a few months.

Do I call Dell and get a motherboard replacement?  My PC is less than 2 weeks old.

cheers

I simply updated my bios and all was ok.

I'm having the same exact problem.  I am running the E7240 with the A10 BIOS and upgraded to Dell Command Power Manager...so now I get a pretty screen from Power Manager telling me the same exact thing.  Can you help us Shawn B?  Thanks!

Just mentioning I've seen this problem once on my E5440 in the two months I've been using it docked.

Can't remember the exact circumstances or what I did to resolve, probably just cycled the power or undocked/redocked or rebooted.

Suggests a wider problem on all recent Latitudes.  I think a large part of the BIOS code is shared between models.

I have the same problem on several E7240 laptops, I have tried the latest bios A14  with no success

When will we se a solution for this error?

No. One of them had an advanced model docking station with 2 24 inch Dell monitors from ~2013-2014. The other user had a standard model docking station with 1 24 inch Dell monitors. I have ~75 other users with similar setups with no issues.

I have seen this so far on maybe 3 of our ~75 e7440 laptops

Hi Shawn, We are seeing the same message with some of our E7240's & E7440's.  The common denominator is that they have the Dell Power Manager software installed and the message appears to be a power manager message.  I have two questions:

1. Is there a power manager setting that needs to be adjusted?
2. Are the docking stations intended to run on laptop battery power?

Thanks

Hi all,

I apologize for my absence! I’ve received clarification from our engineers regarding this error message. While some of you should have found the error message is no longer received after updating your systems BIOS. This update will have no effect for others with 42/45/47WHr batteries installed. This is due to a limitation of the batteries design. For systems with these batteries installed AC power will need to be connected directly to the system as they will be unable to receive the correct charge through E-legacy Docking stations.

Latitude E-Legacy dock requires A/C power with some system batteries.

If anyone is receiving this error even when the system is connected directly to AC power or with one of the other batteries offered with these units installed the message is likely due to a battery that’s reached the end of its life or a faulty/ damaged connection to the motherboard.   

Hi,

How do you tell if you have one of the affected batteries?

cheers

Hey dangeroursdan,

You can confirm the battery version installed in your system by checking the serial sticker on the battery its self:
