Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

Remove the battery and the AC adapter from the laptop.
Press and hold the power button for 60 seconds then let go
Plug the AC adapter only back into the laptop
Now press the power button on the laptop
If it now boots properly shut down the laptop and insert the battery
Now push the power button again
If it now fails you may have a bad battery

Pluged aspire 4520 in at night. next morning, no lights no power. nothing


if the unit will power one with ac adapter plugged in then you have a bad battery. check to see if you dc jack on the lap top lights up when you plug in the AC. if it does not light up then your dc jack or ac adapter is bad.

Green light on ac charger goes out when i plug it in to lap top


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

This problem is either due to your power adapter, wall plug or the back of your lap top where the power adapter goes into. My guess would be the power adapter, they are infamous for going bad. Try wiggling the cord that connects to the power brick (black box) from your lap top.

My lap topwill not turn on.


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.

Not starting


Just to sum it up, are we talking about the Dell Inspiron 1750 or a Dell Inspiron 6000? Seeing two different things here. With the regards to the ac adapter, How "Warm"are we talking about here. 1 to 10. "1" 100 below 0 or "10" Nuclear Reactor Hot? Any adapters can get warm to the touch without overheating and frying. Was there a blackout or power outages in your area or T-Storm on the day you left. Take off the battery from the laptop. Check the battery lights. Do they flash or do they all light up when you press the button. With the laptop not working, lets hope the battery didnt fry the mainboard. Have you try to fire it up again after the adapter has a chance to cool down. By now, it should be fine, if you haven't use it.

Let me know

It could be one of three things. It could be a bad battery, a bad ac adapter, or the recharging circuitry could be bad. I would try pulling the battery out, and see if the laptop will startup and run strictly off of the ac adapter. If that does not work, you have a bad ac adapter. If that works, and the battery has any charge left, try running it strictly on the battery. If it doesnt work, you have a bad battery. If it does work, the circuitry is bad and you will probably need new motherboard. One other thing you can check is where the ac adapter and battery plug into the laptop, and make sure there is no corrosion that could be causing a short.
