Go to SolutionDell venue 11 pro power adapter problem
I have two power adapters replaced already. When starting from cold power up, it displays a message: "Alert! A 3W AC power adapter has been detected, which is less than the recommended Latitude xx 23W AC adapter originally shipped. This will increase the time to charge the battery ...." I was told to only charge up the tablet and then unplug the charger. If the charger is connected to the tablet continuously the charger will be damaged as indicated above. It seems it is rather inconvenient to have to remember to disconnect the charger once the tablet is fully charged. Any one has similar experience?

Actually, I have this problem on both a Venue 11 Pro, and, an E6510. The problem appears to be related more to a driver or Bios issue. I went out and purchased genuine Dell Power Supplies for each unit, and have the same problem. Please provide another solution. Perhaps, Dell or Microsoft is the key to this issue. I really do not think it is a hardware problem, as even the connectors on the tablet, and the laptop have been verified by a certified dell repair facility. So, Please get us a soulution that works. I even moved back to Windows 7 Pro, and older rev of the bios, and all seem fine after 2 weeks. Now, I am not sure which is the actual fix, but, I suspect that there is an issue with the BIOS updates. Also, the repair center verified that both my power supply & cables for both units were working. They also suspect a driver or BIOS problem associated with windows 10. Please look into this, and elevate to a level 3 status.

I just received my new Venue 11 Pro last week. Having the same problem. Its not the charger and its not the cable - I tried a different charger/cable and receive the same error. Its something in the tablet. This shouldn't happen on a brand-new out-of-the-box tablet!
It is nice to hear that it is OK to leave the adapter plugged into the tablet after the battery is fully charged. But it was rather unsettling when I was told by a Dell responder that it was not OK to do so. She helped me updated all the software and drivers on the tablet and still had the same message. I think we isolated the problem to the USB cable, but a new charger and cable was sent to me.
Similar question:
I have a high power USB charger (40W, 5 ports) which will charge multiple iPads at full current, so it can easily do more than the Dell 24W charger at USB voltages. However, with it, the Venue 11 Pro 7140 complains about having a 3W charger on startup, but does say charging once I get in to Windows.
Is there something different about the Dell charger? I notice the model I have (HA24NM130) is actually labelled 19.5V, 1.2A or 5V 2A. It seems odd to have two voltages listed on a charger that has only a USB output.

Hi Mort. I had a very similar problem with my new Venue 11 Pro. I thought the Dell charger was bad, so I tried another charger I had - same problem. So I then thought the tablet battery was bad, and had Dell send me a complete new tablet (with new charger, cable, etc.). It ended up that the cable they supplied from the charger to the tablet was bad (the second one worked fine). Bad may be the wrong word - I think there's a subtle wiring difference (which is why my other charger didn't work either) in that cable. I packed up the second tablet, second charger, and first charging cable and returned them to Dell - kept the first tablet and first charger- but the second cable - and all has been flawless since then.
Its probably the charging cable...I don't know what the subtle difference is...but there is one.
Curious that Windows reports "charging". It may be, but the charge rate is so low as to be almost nonexistent.

I don't know...I don't even know what to ASK for...all I know is bits and pieces of what I've found here on the forum. The cable from the second tablet they sent me worked fine, so I kept it and sent the first cable back along with the new tablet and charger. Some work and some don't...may be tied to a subtle wiring difference. Definitely not a one-off bad cable, because I tried a couple different ones that all work for other devices, and they didn't work either.
When I asked Dell about this, they acted like I was speaking a foreign language (I guess I was...English!) - they had no idea what I was talking about.
I don't know if you bought a docking station with your tablet, but if you did, you can charge it while its on the docking station...no need to rely on the stand-alone charger in that situation.
It is looking that there is any problem in the circuitry of the charger. You must go for the specifications of the charger and the tablet. If there is any kind of the warning as you mentioned by the manufacturer then you must take care of it. You must look for any other charger.
While i get the same message on boot up on my Venue 11, it seems to charge just fine. My work around is to unplug the charger from the tablet, boot up, then plug the charger back in. No error message, tablet charges. Yep, shouldn't have to do this, but it works.

The 3 watt message means that your AC adapter has tripped, most likely due to a short in the USB cable. To find out, unplug the AC adapter from the wall and tablet. Plug it back into the wall and then the tablet. Turn on the tablet and see if you still get the same error. If so, you should replace the adapter and cable. if no error, then you should replace the cable. If this persists with a brand new cable, then you could have damage to the internal micro USB connector in the tablet.
Leaving the adapter plugged into the tablet after the battery is fully charged is completely fine and won't cause any problem. The tablet and battery are smart enough to quit charging once at 100%.
