Disable Sleep Mode When Closing Lid?

Hey Folks,

1 week mac owner here. I just converted from Vista and am having trouble finding a feature I use in Windows.

I usually like to keep my laptop running with the lid closed for extended periods (primarily when downloading). How can I disable sleep when I close the Macbook lid?

umm well your not suppose to thats why apple didnt include it as an option

the only way i know is to have external screen plugged in, or plug usb devise in shut the lid and then pull the devise out once a sleep

this is not recommended

Well that stinks if you can't do it. I have a jumpy cat who'll walk over anything which is another reason I prefer it closed and running.

I hope they add this feature!!! Especially since Windows has it!!

That just might be the reason why they wont.

When I switched from PC I was really upset about the sleep not being an option. But I've gotten used to it and putting it to sleep really doesn't bother me. They're quick to wake up and reconnect to the internet.

re:

If you want to disable it, you can take the magnet out from behind the screen. Just take the front screen cover off and there is a small magnet which when removed, disables the sleep when closed function. I'm not entirely sure if you void the warranty when doing this, but it works.

+1. My school uses this all the time to run Macs on robots.

On the old Powerbooks, InsomniaX isn't enough as it still has a thermal shutdown that is lower when the laptop is shut than when it is open. A washer or other thin piece of metal (wrapped in paper to prevent scratching the mac!) placed on the trackpad will disperse the magnetic field enough to trick the powerbook into not sleeping.

Don't do it, the heat dissipation with the lid close will be terrible !

Set one active corners to sleep display and leave it opened and disable the computer sleep in Enery Save prefpane.

I needed to disable the lid sleep feature on my 2007 MBP, as it kept on coming out of sleep when it was closed in my bag. I'm guessing the magnetic sensor used in the lid momentarily moved at some point, causing it to wake up.

Forget all those other solutions, this one is the cleanest and quickest:

Open up Terminal and type:
Code:
sudo pmset -a lidwake 0
This will disable the sleep/wake feature when opening or closing the lid.

To reenable it, type:
Code:
sudo pmset -a lidwake 1
To check the status of the lid wake feature type:
Code:
pmset -g
And look for the lidwake value.
0 = Disables
1 = Enabled


Hope that helps,
Dan

Energy saver will only override software settings, when you physically close the lid (clamshell mode) the built-in hardware will override whatever setting you set in preferences. Only way to do it is to install a after-market utility called insomniax, to avoid your MBP/uMBP from over heating also install SMCfancontrol and if possible prop up your macbook like a book with the display clutch facing up - allows heat to dissipate quicker -
