The suspend function is somewhat hardware dependent. Indeed the whole 
ACPI process is hardware dependent.
Many machines use ACPI perfectly but some most certainly do not.

Amongst the computers which do not work correctly with ACPI are some 
Samsung models.
In my Experience ASUS are amongst the ones which work the most correctly.
(You have not mentioned the make and model of the computer (or 
motherboard) or which Distro you are using)

When I install a Laptop, one of the final checks is shut the lid and 
after some seconds open it again. It should come up with page asking for 
user password and after some seconds the Wi-Fi connection re-establishes.
I do not waste time trying to solve the problem if it does not work 
correctly as, again in my experience, with each update of kernel the 
situation improves.

As example one particular Samsung would not power down and had to forced 
(by holding power button for more that 5 seconds) and then a new 
release, and now it worked correctly on the power down but it still does 
not resume correctly, maybe next year? (using Mandriva, my favourite Distro)

As regards the 'NEVER' look at your 'Preferences-Screensaver' and 
'Preferences-PowerManagement'
