Mac doesn’t respond after sleep mode: how to Prevent this

hangsleep-wake

My mac often doesn't respond after sleep mode. What can be the reason?

There are a lot of articles about what to do in this situation. But I can find nothing about how to Prevent it.

Mac is macbook Air. OS is OSx 10.7.4

I had the same issue on my mini. The first thing you might try is resetting your PRAM and then your PMU. These control sleep on your mac. If they fix it, and it goes bad again, you may need to take it in for warranty repair (if under warranty.)

I had the same issue on my Macbook Air and Mountain Lion.

The quickest way to solve this is to disable the login screen or the "ask for password" setting.

If you're worried about privacy, do the following:

Reset PRAM
Reset SMC

If it still doesn't work, disable deep sleep mode (hibernate) by doing this:

sudo pmset -a hibernatemode 0

Note that doing the above will only put your computer on battery sleep and this will affect battery life when you're not using your mac.

Make sure you are using the laptop with the correct model magsafe charger - if you use a different model's charger, eg a 15 inch 85 watt charger or such, it can cause this problem to occur. A reset of the PRAM would normally cure the problem temporarily.
