G780 started up then shut down, no indicator lights when plugged in and will not sart up


Is the ac plug loose? If you wiggle it does the light come on and off? If that isn\'t the case and it powers up then goes right off sounds like an issue with your motherboard. If the unit is under warranty I would contact Lenovo. If the unit isn\'t under warranty you should try to blow it out with can air to get all the dust out of it to see if its a simple over heating issue. If the unit still doesn\'t post, sounds like you have a bad motherboard. Let me know if you have any other questions. Good place to find more info: http://support.lenovo.com/en_US/

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.

Battery light on nothing else


Has there been ANY damage? Have you tried another Cord/Charger with the EXACT same power specs? Has the AC jack been damaged due to pulling on the cord while plugged it? Unplug, remove battery, plug in, try to reboot. Has it been overheating? Fan, vents, heatsink clean?

Battery appears charged, but computer will only run when plugged in


does your battery have one of those charge indicator panels on bottom?

also, it's possible that the connection from battery to the internals is shot..if that's the case, then you're looking at a major motherboard swap
