This happens to me periodicly on my laptop also. Unplug the power adapter from the wall and from the laptop. Then plug everything back in. It should work now.

I have a dell Insiron 1526. we thought it was the power port and changed it. they charger shows a green light when plugged in and when you add the computer it starts blinking but the computer will not turn...


try to use a different power adapter or try your ac on a different system so you can determine if the issue is with the ac adapter or on the system. if the power adapter works on a different system, try to remove any external device as well as the ac adapter and the battery. while the ac adapter and battery is out, press and hold the power button for about 15seconds. then reconnect any power source and turn on the system. if it still doesnt turn on, remove memory, expansion cards, hard drive and optical drive then turn on the system. if it's still not turning on, the motherboard is faulty. but if it do turned on, reconnect the removed components one by one so you will determine which component is causing the issue. hope it'll help. good day. =)

When I turn on the computer I get an error message that starts "The AC adapter type cannot be determined..." - The green light on the adapter is on. - When I ran the battery diagnostics, the adapter failed...


If the BIOS cannot ID the charger, the battery will not be charged.

Cause:

There is a fine wire in the middle of the canon plug to the computer, that sends an ID of the adapter to the BIOS. If that pin is bent or broken, then the system will be powered, but the battery charger is disabled. If another AC adapter for a Dell D-series is available, see if the issue goes away with diferent adapter. If no adapter is available, they are <$50 on Ebay.

If you replace the AC adapter, and the issue still occurs, then you'll need to replace the motherboard.

I have a Dell Latitude D610 and it was apparently working until 24 hours ago when I used it on battery mode for 1 and a half hours. Currently when I switch it on, I constantly get this message that my AC...


When the message about optimal performance comes up, are you given an option to press F1(or some other key) to continue? That is normally the case. If you see that, press the key and let it start normally. Once it has started completely, do a full shutdown. Disconnect the AC adapter from the computer and from the wall. Let the system 'rest' for a few minutes. Connect the adapter to the AC power and check to make sure the GREEN led light on the transformer is lit. If it is, connect the power supply to the computer and start it.

Good luck and please let me know how it works oout for you.

No power


Unplug All External Devices Unplug the AC Adapter From the Wall Outlet. Disconnect the AC Adapter From the Laptop Reseated the power cable to the adapter.
Remove the Battery Connect the AC Adapter Directly to a Known Good Outlet, But Not to the Computer Verify That the AC Power Adapter Has a Solid Green or Blue Light.
The AC adapter status light is solid green. The AC adapter status light is solid green.Press the Power Button and Check for POST. Post means if you see the dell logo,remove the battery, plug the ac if still it wont turn on or doesnt have any light,Reseat the Memory if after reseatting the memory still the same problem it might be a bad motherboard.

Dell Inspiron 1501 AC Adapter error message


The Dell 1501 ac adapter (possibly other Dell’s as well) has been known to be problematic because of its lack of a plug to jack secure fit. You will notice that the plug can all too easily be pulled from the jack, as opposed to other systems where the plug fits more securely onto the jack. The plug and jack combination is poorly designed so that over time, the plug will come unseated depending on how much movement the machine is subjected to. This will result in power error messages or outright power-up failure. So before assuming you have a faulty adapter, make sure that it is not just a loose plug that is causing the problem. If you look inside the jack, you will notice that there is a 3mm region of non-conductive material nearest the surface of the jack. Use a strip of standard electrical tape 3mm wide and long enough and wrap it around the base of the plug (you may need more than one layer of tape to get a good fit). I have used this method to secure my plug and it has served me well. If the tape comes undone over time, just simply replace it. A more “elegant” method would be to use an “O” ring of the appropriate size (about 6mm) around the base of the plug in lieu of the tape.
