Got HDAPM working, but now my MBP won't sleep....help

[jon08]

Hey guys,

I recently got my early 2008 MBP stock drive replaced with Scorpio Blue 500 GB. However, I've been highly irritated by its constant head parking - every 20 secs or so. The clicking was driving me crazy. As a result, I decided to try out HDAPM.

So far it seems I got it working; I have heard no clicks/clunks in the past 25 mins!

However, there's a little problem: now when I close my MBP's lid it will go to sleep for a sec, then resume running. Yet, if I choose "Sleep" option from the apple menu in the upper left corner, it will work.

How could I get my MBP sleep to work again upon closing the lid?

Please help.
