Why is my battery light turn off when I connect the charger.

Whenever I connect a charger to the laptop. The laptop battery light turns on for 3 sec and then turns off again. Then I disconnect the charger and again connect it with some force. then the light turns on and goes off again and after 2 sec, it turns on again, and the laptop starts charging and shows the time remaining to complete charging. Otherwise when the light goes off after 3 sec laptop shows (plugged in). I don't know when this is happening. Sometimes it takes 3 to 4 times (disconnect and connect) to start charging.

Hi,

There may be a problem with the power connector port (aka DC-In jack) in the laptop.

Sometimes the inner +ve conductor of the jack can fail intermittently causing no power to be received by the motherboard from the charger.

Here's the owner manual for the laptop. Go to p.28 to view the procedure to remove /replace the power port connector.

Follow the procedure and just disconnect the power port cable plug from the motherboard and then connect the charger to the power port. Use a voltmeter to measure the voltage on the red and black wires of the plug. If there is 19V DC when measured at the port's cable plug, then gently move the charger's plug up and down and side to side (not in and out) inside the power port to see if the voltage remains constant or comes and goes.

If it comes and goes the jack is faulty and will have to be replaced as it cannot be repaired.

Search online for 8GJM9 to find suppliers that suit you best.

Charge port could be damaged, especially if you have to use force.

I’ve got the same issue and a new DC in port has not resolved it. Any ideas?
