Laptop power lights won't come on

Plugged in ac adapter and green light is present on the adapter but the power lights on the laptop don't come on. Is the Mobo dead or is there something else I can do to get it to turn on?

    None of the lights on the laptop come on, only the indicator light on the ac adapter. Not sure if the battery is dead or not. There is no external indicator on it, only power levels when the computer is on. I didn't think about radio shack, I'll give it a try. thanks.

Does neither the charge nor the power light come on? Most Dell batteries have a button on them that you can press to determine how much power it has left. If your battery still has power try turning the computer on, and once you get into Windows see if it will detect the power cord or not.

If you can't get the machine to boot you can try your local Radio Shack. They normally have adapters for every laptop, and ask them if you can try it in the store to get your computer to turn on. If that cord works then something is wrong with your AC adaptor.

If neither cord works then either something is dead on your motherboard, or the power jack on the back of the laptop is loose (and not providing any power.)

No a/c power light on laptop


Hello

Well the first thing you should check is the amount of power output to the power supply. for example the computer needs 12V but the AC Adapter only gives 9V.
If that's not it then the actual green light is not receiving that information from the motherboard. that's not an issue if the battery get's filled up and the laptop works normally . If you notice that the laptop tends to shut down quickly when it's not plugged in then the battery is worn out. These things happen since the a laptop battery becomes very inefficient after 2-3 years.
One more thing - try to rotate the input end of the ac adapter cable. maybe it's not making good contact inside the laptop.
Hope this helps.

Is the battery charging when you plug the power supply? If not, while the battery and the power supply is plugged in go to BIOS, that will be F2 when your computer boots up, from there check on battery health or battery info you will also see the ac adapter if it's detected if it says unknown try to use another ac adapter if it is detected still try to use another adapter. If you still have the same problem after trying a new one. You'll need to replace the motherboard

Not charging


which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

Battery has gone dead. When I plug the A/C cord in the light on the charger immediately goes out and won't charge battery.


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.

On the issue with th ebattery on the 1521 inspiron. Took battery out and plugged in still will not power up. Could it be the adapter as well?


On the ac adaptor, look for a green light that will turn on when you plug it into the wall outlet, if its on that means the ac adapter working. If you get a green light on the ac adapter but then the green light goes away when you plug it into the laptop then that means the laptop has a bad motherboard.

If you plug the ac adapter into a wall outlet and get no green light then that means the ac adapter is bad and you would need to get another one.

I have a Dell D600 (PP05L), its not powering up no lights. I noticed on the power adapter the green light goes out when plugged into ac power. What could be wrong here? please help


Hook up your power adaptor to ac power without it being hooked up to the laptop and see if the green light stays on. If it does then you know your adaptor is okay. if your adaptor is only hooked up to ac power and the green light still turns off then you know your ac adaptor is bad.

Take out the battery from your laptop. Now hook up the ac adaptor to the laptop and if it stays green then you know your battery is bad but you also want to make sure you can get your laptop to turn on. Hopefully it will turn on with only the ac adaptor hooked up to it.

Ac adapter light is solid green, but when plugged into laptop...


the most likely reason is a systemboard problem (the ac plugin port cannot changed independently for notebooks)

AC Adapter


Two possible solutions are present; one is that you have terrible luck with said adapters. The other is that you're using adapters with too much or too few milliamps or volts. If the specified rating on the adapter doesn't exactly match the power consumption for the computer, then it will become strained or vice vera and it won't work.
