This guide will help you remove and replace the DC Power Jack for the HP Pavilion x360 14m-ba114dx. The DC Power Jack is tasked with directing the charge taken from the AC Adapter Cable (charging cable) to the battery. The symptom of a failed DC Power Jack is that the laptop is not charging, which may cause the laptop to not power on at all. For more information on a laptop that will not power on consult [[HP Pavilion x360 14m-ba114dx Troubleshooting|this page]].
Finally, a prerequisite to this guide is removal of the battery. If you notice once the laptop is open that the battery is swollen, remove it with caution. If swollen, do not charge the battery, keep the battery at a stable room temperature, and dispose of it properly at a recycling center.
