Hold the power button First, try holding down your phone's power button for 5-7 seconds. This usually restarts a phone.
Troubleshoot your cable, charger, outlet & case

1. Use the charger and cable that came with your phone. To check that the charger and cable are working, try them with another device.
2. Check that the cable is securely connected to the charger and to your phone. Check that there's nothing in your phone's port, like dust or lint.

   • If you see a battery icon, your phone is powered off and is charging. You can restart right away.
   • If you see a red light, your battery is fully discharged. If the red light is flashing, there isn't enough power to turn on. Charge your phone for at least 30 minutes before restarting.
   • If you don't see a battery icon or red light after you plug in your phone, the issue could be with your screen.
   Tip: Battery icons and lights can vary by phone. For your phone's details, contact your device manufacturer

Hi David
It sounds like a fault to its power transition section circuit. Actually, this circuit is built inside the mother board to your laptop.
Please contact the authorized service center, and describe and show them the problem you do experience now, with your laptop. It can be rectified. Gopakumar Gopalan Google

If possible test with another charger like a car charger if you have one
also try removing the battery plug in the charger and put the battery back in (don't touch the contacts/gold pins)


if it works with other chargers then the charger is bad


if it doesn't work with other chargers charging port/battery/phone is bad

does it show that it is charging from the charging light/power supply? Is there any life left in the battery? is the charger charging the battery? the batteries dont last in laptops usually about a year before the go bad and have to be replaced, Is the charger working? The chargers go faulty all the time, The little plug that plugs into the laptop goes faulty and is a very common fault and doesnt charge/power the laptop, The only thing you can try is another power supply of the same name/model/output voltage and current with the same small plug and polarity or another battery of the same type/model, If you can do this and it doesnt cure your fault it needs looked at by a technician, Hope this helps, If you need more assistance let me know,

contact apple and see what they say. if they cant fix it or something, then look for instructions on how to change the battery. if you dont wanna do that, then get a new one, but recycle that one first so you can get some money to pay for the second one

When plugged in does the battery charge, and do any charging lights on the laptop illuminate. If not then either the charger or charger circuits have failed. The former requires a replacementm charger, I suggest e-bay. The latter requires an expensive motherboard replacement. If all lights are as you expect them to be, and the battery charges, then there could be some obscure setting, or software, that causes this but hardware would be my first suspect.

Please take a moment to rate my solution.
Thanks.

First thing check that the battery charge light is on when the battery and the charger are connected.
If it is it indicates that the power supply is charging the battery,
If it isnt it may indicate a fault with the battery or that the charger is not compatable with the laptop or that there is a fault with the charger.
If the battery is charging then try running the laptop on battery only without the charger and on charger only without the battery.
This will eliminate which one is faulty.

You mentioned that if you wiggle the cord then the light comes on again.
Check to see if the charger end plug is lose or the actual port on the laptop is lose.
If the charger plug is lose then return to seller and make sure they gave you the correct charger. if the actual port on laptop is lose then perhaps u got a bad connection and you need electrician or local laptop technician to open it up and solder properly on motherboard.

Let me know how it goes.

GO into the control panel and check your power settings. You might have it set to use less power when plugged in.

Charge the unit over night, Plug in the AC charger and you should see a lightning bolt over the battery bar graph display.

With the charger plugged in, gently press and hold the on/off power until the screen goes black and displays the text "Charging battery". After a few seconds, the screen will go black to conserve power. At any time, you can press the screen and it will light up saying its still charging.

If you let it go over night, when you touch the screen, it will say Charging Complete and you can then remove the charger. You should have full green bars on the battery indicator.
