It is unfortunate that the computer is not turning on. Request you to try following the below steps which might help:
(1)Turn off the computer.
(2)Remove all the external peripherals like AC Adaptor, flash drives, battery, etc.
(3)Press and hold the power button for 30sec which releases the static on the computer (if any)
(4)Put back the battery and plug in the AC Adaptor.
(5)Let the computer charge for some time.
(6)Try turning on the computer.
If the computer doesn't turn on then check hoe the Power LEDs on the system, battery and AC Adaptor react. Then I can check and help you further.
"Battery being charged" indicates that this is a laptop. Auto shutting down indicates that you are having issues with the power supply/brick. One thing to try is another known good power brick. Otherwise it is likely your power inverter inside the laptop.
Remove your battery and try with external power supply again if it boots up all good and proper then after booting to SOE refitt the battery and let it charge - if it doesn't boot or power on look to see if the blue LED it on around your power input point. If there is no illumination around the power input port try another 65w power supply input - your power pack may be dead. Cheap fix - if it still does the same powers on then off - you have reason to go out and buy a new laptop - would be cheaper than replacing the M/board trust me.
Four possibilities come to mind. 1. Your power supply is bad and the battery ran down. 2. Your system board died. 3. You have a bad device plugged into a USB port. 4. Your battery is bad and holding down the AC power. To troubleshoot, disconnect all external devices, even remove the CD drive if possible. Try to boot. Next, boot with just the battery. Next, boot with just the AC supply. That's about it. If you still have no power at boot, it is the system board.
Take the battery out and try to boot the computer up with the external power supply.. If this works the the battery is shorted. If it doesn't then you will need to try another power supply, if that doesn't work then something internal has shorted in laptop
This happens when the battery dies and there is insufficient detectable power to run the boot system. You must change out the battery with a fresh one, or plug in a good external power supply to get things started.
You may also need to let the internal battery charge a short time before the boot system sees enough available voltage to start all systems.
Have you considered it could be the battery has died. Have you tried external power? If the battery is OK then check the battery contacts to make sure they are clean.
Has your power supply died and it won't power the laptop or charge the battery?
It could be the motherboard but I'd put my money on it's power supply or battery. Without more details being supplied.
