I have a Dell Inspiron 17 5000 series 5767. Only powers up for about 5 seconds then shuts down. At first, I thought it was the motherboard but was not 100% sure. First thing I did was to buy a new charger. I left the charger on overnight and was able to power up and use the laptop. I now get a message that the charger is not recognized and that it is not charging. After about ten minutes the laptop shuts down. If I put the charger on and leave it overnight it will power up and run for ten minutes then shut down again. What could be wrong? My laptop is only about a year and a half old. Any help will be greatly appreciated.
