Dell d610 wont turn on ac adapter light is green

The computer doesn't need any drivers to recognize an AC Adapter. If you have purchased the correct AC Adapter for your laptop then it should just work when you plug it in. If it does not then my guess is either you have received a faulty AC Adapter or the DC Jack which you plug into in the back of the laptop is bad.
I am assuming your battery is dead and when you plug it in and turn it on nothing happens?
You can also try taking the battery out and try to power it on with the AC Adapter plugged in.

The Dell Latitude D610 takes a PA-10 or PA12 AC Adapter. It's 65W or 90W

For 90 watt Adapter the output voltage on your AC Adapter label should read 19.5V and 4.62A
At least that's what the Dell brand reads so it should be close to that.

This is possibly an internal power Supply fault. take the battery out, plug in the adapter, IF the unit works now, you have A: A battery problem, or B: a charging circuit problem. If the unit still fails to work, the power supply in the PC has faulted. You need to get a "Quote: for a repair.

Your adapter is faulty. I've seen this a number of times...

This indicates a short in the computer or power supply. The power supply senses the problem and shuts itself off. Does the laptop run at all? More info. is needed to correctly solve your problem. Send me a message and I will help you out. Phil

try connecting ac adapter alone without the laptop, check if ac adapter light will stay green or blue.
try another power outlet using the ac adapter alone without the laptop check if the ac adapter light will stay as green or blue. if all fails replace ac adapter.

if ac adapter stays green or blue try connecting to the laptop without the batt, check if the ac adapter light will stay on, if yes then try connecting ac adapter to laptop with the batt plugin check if the light stays green. if not update the BIOS. if fails replace motherboard.

check if the power ac adapter pin the goes to the side of the laptop is damage, if not then try connecting ac adapter with laptop to a diff power wall socket, if fails then replace the motherboard.

Please check the AC adapter with another system and confirm if it is working fine. Else get it replaced.

Turn off laptop, Remove the battery and the power cable and press the power button for about 30 seconds.

Check for light on AC adapter.
Try with battery alone. Try with AC adapter alone.

Try with a different adapter of the same kind.

else the issue could be with the main board for which I would request you to contact the manufacturer.

Try to check if your AC adapter has a light itself. If it the light is off. Then try a known good adapter. If the AC light is green, then try to wiggle the cord from the port and see if it ain't loose. Try to also check if the AC pin is not bent or broken.

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.
