The laptop is not turning on

Hi @abdullahfa35720

If there's no indication that power is connected to the laptop, first check that there's 19.5V DC on the ouitput plug of the charger. If you don't have a voltmeter, then try using a compatible charger and check if it works OK.

If the charger is OK then 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 causing no power to be received by the motherboard from the charger and the battery won't be charged either.

Here's the maintenance and service guide for the laptop. Go to p.40 to view the procedure to remove /replace the power port connector.

Use the procedure to just disconnect the power port cable plug from the motherboard (you don't have to remove the port from the laptop) and then connect the charger to the power port in the normal manner. Use a voltmeter to measure the voltage on the red and black wires of the plug.

If there is 19.5V 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 there is no 19.5V DC when measured at the port's cable plug or if it comes and goes the jack is faulty and will have to be replaced as it cannot be repaired.

Search online for 857438-010 to find suppliers that suit you best.

If there is a constant 19.5V DC voltage at the cable plug then the schematics for the motherboard would be needed to find out what's wrong
