It usually blinks when your PC is in suspend (either hibinate or sleep) mode.

Don't worry about it - its normal.

Might be going bad if it is an irregular blink. Power cord (to the switch/light assembly) might be backwards if its a steady blink.

Not a real problem, wouldnt worry about it.

The weird thing is it used to not blink at all unless it was in suspend mode or I was shutting the system down or starting it back up,it would blink then for a few seconds.But now it blinks constantly.
