AC adapters, also known as "the brick" often fail and you can find replacements at Dell or on the internet. Be sure to order one with the proper output, see info printed on the brick. It does not have to be a Dell product, generic is fine. Before ordering make sure you are getting power to your plug outlet, borrow someone else AC adapter. A short test should not harm your computer; use your adapter on their computer. Remove your battery, clean electrical connections with a pencil eraser, re-install battery. With your AC adapter plugged in, check battery icon in lower right hand corner of screen to see if adapter is plugged in and charging. You need to test before you buy something you don't need.

not sure, but make sure the cords are fully connected and the connection is fully inserted in the laptops port. I have no problem with mine.

well I never had problem of ac adaptor with mine although I returned the laptop back due to excessive movement of the cursor or would I say the mouse was so fast that it kept on dragging app on the interface when I move it around to click, anyway try check if your ac adapter is working by plugging it to the laptop and check if the laptop battery shows signs of charging by looking at the right hand lower corner screen where battery icon is to see if it shows or says battery charging, if nt then knw the ac adapter is nt working before you can think of replacing it with a new ac adapter.

I bought a converter for less than 4 bucks to fix same problem. http://www.ebay.com/itm/321593667135 From what I've read, not all USB ports supply enough power. The USB Port Jack Wall Charger AC to DC Power Adapter Converter got me going. Good luck with yours!

A volt meter will help here. First, check the 120 volt AC outlet that the transformer is plugged into. Do you have voltage? Also, be certain that the outlet isn't on a switch. Next, plug in the power adapter to the the outlet and check the voltage at the coax outlet of the adapter. No power probably means a a bad adapter. If you have power, place a piece of coax on the power adapter and check for the proper voltage at the end of the cable. No voltage probably means a bad cable. Disconnect the power adapter from the outlet and connect the power cable to the proper connector on the 2400. Plug the power adapter back in. It should work. A volt meter will help here.

I had to get the AC adapter extension. I bought it on Amazon for I believe around $2 or so.

I would check that all connections are not loose. It sounds like you have the power usb cable plugged in but check it's connection as well. I'd suggest contacting the company if you have further problems. My monitor has worked flawless since installing the adapter. Sorry to hear you are having issues.

I just plugged it in with no adapter, and it works fine. I'm sure you could use an adapter as well.

I got the same error when I tried using an ac adapter that was too small. I purchased the tenergy 12v adapter and it worked perfectly. I hope this helps.

Hello,The plug is grounded. This is the same with the 2ft versions as well. Hope that helps!

Make sure it is seated properly and the power cord is in a functioning outlet. Mine charged immediately and works fine. If that doesn't help, I would return it and request another.

I don't own the unit yet however yes this does require an AC adapter. It looks to be on the front of the unit in the bottom left corner (look at the 3rd picture you can see it).

Unplug the power adapter from unit, leave it unplugged for about 5 mins and plug it back in. This procedure has worked for me

It means that the AC adapter you are using isn't powerful enough to power the charger. The error is Input Voltage Error. I suspect you are using a different AC adapter than the one offered specifically for the unit?

Sounds like the adapter blew. If the green light is out, that has to it. My guess is they would send you a new adapter.

The AC adapter needs to be plugged in to work. It works great and fast when plugged in!! Happy Day!!
