Has it been dropped or bumped hard?
The hard drive might have come partially unplugged. Can you hear or feel it spinning? Is it a hard drive? Do you have a cover on the back to remove to inspect the hard drive
Will the DVD ROM tray eject?

Battery may or may not be good, but a LT should run regardless on the adapter. You could remove battery and try it only on adapter, but the battery should not be the problem right now.
If only the power light ever comes on, then the problem is likely in the power button board or cables. I find cables loose in HPs frequently. Try unplugging and replugging cables first.
You can find a service manual here. Click "Download" at the top left.
Search "power button" in the document. (ctrl + F)
