My laptop comes on with dell logo screen then goes blank in 10-15 seconds. Three of the green indicator lights are on, then everything shuts off in less than 10 minutes.
Connect an external monitor to the laptop and see if you can see what is happening on that.
It is a possibility that your inverter is faulty and will need to be replaced. They will normally power on for a few seconds, then cut out.
Remember to set the laptop to use the external monitor with the function keys.

I replaced the LCD, and that made it stay on.
