There are some reasons why unit wont turn on. Incorrect power supply, Damaged talc switch button, bad battery, defused fuses in power primary circuit supply section, and defective components in power supply circuit.
Remove main battery and power up, if no change, the DC jack in the laptop is a common source of trouble from no power to intermittent operation. The laptop will need to be dismantled down to the motherboard level to to access.
try taking out the battery from the back of the laptop, wait a few seconds and then connect the laptop to power through the ac adapter. Now try to boot back up the laptop. If that works, pop back in the battery and you're good to go again.
If not, there might be some serious problems with the hardware.
Usually for a clicking sound it is the hard drive that is causing this. Try if you can still access safemode. Press F8 continuously after turning on the computer. If you can access that, backup your files and do a system restore to a previous date when the computer was working fine. If that wont work, reinstall the whole operating system. If still not resolved, replace the hard drive.
From the information you provided it sounds like a bad DC jack, first check your power adapter with a volt meter if you have one accessible. If your power adapter is outputting the proper voltage, then within a 95% certainty its your dc jack.
