Question about HP Pavilion dv9628nr Notebook
Press the power button on the laptop, the lights come on for a split second and immediately shuts off. Tried hard resets, removing the battery and connecting just the ac cord. No luck. Received a error code, 0x0000005c

hello the first thing to make sure of is that the ac adaptor cable is not having any partial contacts ofany kind whereby power gets into the laptop irregularly.this could have adverse effect on the circuitry. it is not enough just checking the output of the ac adapter by a meter.try straighten the cable from the adapter and check the meter for voltage fluctuations. if the above is okay then the problem could be on board leve.

This sounds like you have a bad DC jack on your motherboard.
This is one of the most common problems with laptops and can be caused by jarring the DC plug in or hitting it into something or simply from normal use. As a result the pins on the DC jack become loose and consequently do not provide a charge to the laptop and battery. Wiggling the plug can make the loose pins contact sometimes which would explain why it "sometimes" works when you unplug it and plug it back in. Of course if this is the case then your battery is mostly out of power and that is why it powers off after a couple seconds. This repair costs between $150-300 from a professional repair shop and I would not recommend trying it yourself unless you've had experience soldering DC jacks
Another issue could be the CPU fan/heat skin if this is failing or the CPU is overheating the laptop will power off.
Please comment if you need further assistance
