Going to sleep mode (Fn+F4) VERY SLOW - help

[jamess]

I have recently installed System Mechanic and ran partial registry clean. Apart from that i regularly defragment my hard drive, run virus scans etc.

I don't know if the problem with going to sleep mode FN+F4 very slow is due to registry cleaning done by S.Mechanic Pro, but it certainly is slow.

My question is - how do i fix it. When i press FN+F4 it takes about 3-6 seconds beffore computer goes to sleep mode. It always "wakes up" instantly. The problem is going to sleep mode, not resuming from it.

Any help appreciated.

Cheers,
