A less frequent situation that can happen in a laptop resulting in it not booting up is a damaged USB port. If the pins are touching the system will not start up. You can fix this problem by using a small flat blade screw driver, tweezers or micro needle nose pliers to carefully separate and reform the contacts so they do not touch.
This is not a permanent fix because the USB port will become unusable. To fully fix it would require you to replace the system board, which may or may not be covered under your warrenty.

Thinkpad not turning on, Flashing Amber light when battery inserted


The problem is most likely in the DC jack in the laptop, "common issue" the laptop must be dismantled down to the motherboard level, chances are the main board must be removed from the bottom chassis and flipped over to expose the solder joints underneath the DC jack and a resolder touch up done.
