For nearly 15 years I have ALWAYS disabled sleep on all my, and my client's computers.
For 98, and for XP, many computers would not awaken. Hence, unsaved files were to often lost. And lost power ment possible disk corruption. Sleep is a stupid option.
But, hibernate is my little friend. Power button, sleep button, close lid, all enable hibernate mode.
But not on the music comp: no power stuff is enabled.
(For w7 and w8 I also disable ALL assessment and reporting tasks, via the task scheduler.)
My moto, don't try to fix what should not exist.
