My laptop is not charging

Hi @nayandutta ,

Seems as though there may be a problem with the DC-In jack on the laptop.

What can happens is that the centre +ve pin of the jack breaks internally and this opens the power supply path from the charger to the motherboard. Therefore the motherboard won't turn on when the power is connected and also the battery can't be charged to keep it running either. It keeps discharging until the laptop turns off.

To prove this you would need to access the jack's cable plug on the motherboard and test both the +ve centre pin and -ve outer ring connector for continuity between the jack's input side and the red and black wires on the cable plug that is connected to the jack. (unplug the cable from the motherboard before testing so as to not get an incorrect measurement).

Here's the hardware maintenance manual for the laptop.

Go to p.56 to view the steps to remove the DC-In cable. Initially you don't have to remove it, just disconnect it from the motherboard. Once disconnected you can either connect the charger into the jack and check if there is 20V DC between the red and black wires on the cable plug of the jack or use an Ohmmeter to test the jack for continuity. If there is continuity through the jack, wiggle the charger plug inside the jack as it may be an intermittent connection.

If the jack is faulty it cannot be repaired, it has to be replaced. Search online for 90205112 to find suppliers that suit you best.

Ensure that the battery is removed from the laptop, - see p.33, before doing any work inside the laptop, to avoid creating any electrical problems on the board. There is always power on a motherboard somewhere, even when the laptop is off. The power button is not a power isolating button.
