nor are there any of the usual whirring noises of the fan and hard drive
Remove refit hard drive and retry
try booting from a bootable CD /DVD such as a windows or linux disk
Try plugging in an external monitor incase its just a screen fault (you will need to press the Fn + F key with blue square to cycle through lcd to external screen)
last person you came to me with a dropped laptop with same symptoms was a hard drive failure.
