If you tried turning it on with the charger connected but the battery disconnected, then the issue likely isn't the battery but rather the computer's hardware. I will include info for both battery and hardware anyways. Particularly because a laptop frying its power management simply because it discharged, would be odd. Try them in this order.

**Computer**:
With the battery **and** power adapter **disconnected**, push and hold the power button for 15 seconds. This removes residual power from the device. I've seen this trick work on many systems experiencing the same issue you're describing.

**Battery**: It is possible to jump start a li-ion battery. This usually only works if the battery was left unattended for long periods of time and rarely works. I recommend first checking the voltage of the battery with a multimeter. If it doesn't have any voltage, you're a good candidate. If you don't have a multimeter, you can still jump it, but should take precaution.

You can take a 9v battery or another laptop battery and connect positive to positive, negative to negative. You should only do this for 1-2 seconds, disconnect and test for functionality. Leaving the battery connected can result in overcharging, bulging, leaking, explosion.

Good luck.
