Try plugging it into an external display via the HDMI / VGA port and see what happens. If it powers up to an external display, then the LCD on the unit might be bad. If it doesn’t power up to an external display, then it might have a hardware issue preventing it from booting. In that case, you would need to check the manufacture website for the manual that might tell what’s wrong with it based on the lights. Also try removing the battery for 30 min and make sure there are boot disc in the CD / DVD drive.
