MBA 2011 with 10.8.2 - takes time to get back from sleep

[e-r-a-n]

I feel like ever since updating from 10.7.4 to 10.8.2 the time it takes since opening the lid till i can type my password again takes much longer.
It turns the screen on almost immediately but it takes couple of seconds till keyboard lights turn on & i can type my password.
it also seems like it takes longer times if the computer sleeps longer.. like human beings

i request to re-examine my thread..
Nothing helped.. so far it continues.
I tried to reset the smc chip, by powering on with shift or some other key, i dont remember as it was few days ago

i read around a few threads regarding the same isue, but with no possible fix so far.

please help me
