When I plug in the charger to my HP laptop, I get a notification that reads "The Smart AC Adapter is not functioning correctly". I have tested another adapter and have gotten the same result. I took the battery out to try to run it directly from the AC adapter and the power button lights up for ~5 seconds before going dark. Once again I tried different adapters and outlets to no avail. I've had this laptop for less than a month. Could it really be a motherboard issue already?
