Hi @spooner06 ,
If there is a problem with the power into the laptop then the battery cannot be recharged and will discharge if the laptop is on and eventually the laptop will shutdown and it cannot be restarted until the charging problem has been fixed
If there is no indication of power on the laptop when the charger is plugged in it may be either a faulty charger, a faulty DC-In jack (supplier example only) or worst case a problem on the motherboard.
Check that there is 20V DC on the output plug of the charger or if you haven’t got a DMM (digital multimeter) try a different known working compatible charger and check if it worked.
If the charger tests OK or you have tried a known working compatible charger check that there is a good electrical connection through the DC-In jack by using the Ohmmeter function of a DMM to test for continuity through the charge port to the motherboard. Most probably you will have to remove the motherboard to access the soldering side of the charge port on the motherboard.
Here’s a dis-assembly video which may help you. The charge port can be clearly seen at the back of the motherboard at 1:04 minutes into the video.
If the port is loose or faulty is will have to be resoldered or replaced.
If doing this yourself seems all too daunting, contact a reputable, professional laptop repair service and ask for a quote
