[SOLVED] E6230 - Does not sleep on lid close (Sierra)

[ryanswj]

Hi guys,

 

I managed to get Sierra working on my E6230 (i5-3320M BIOS A11) and everything is working fine.

 

However, the laptop won't sleep on Fn-F1 or lid close. Needless to say lid open does not do anything.

 

It seems like the laptop doesn't detect the closed lid. What can I do?

 

Thank you!

Fn-F1 shuts down my E6230 under Sierra. Last time I encountered a similar behaviour, it was on the E6440 and I fixed it with a mod of the CPU-specific generated SSDT.

Closing the lid or clicking Apple menu->Sleep does put laptop to sleep however. Make sure you've set hibernation mode to 0 (i.e. disable hibernation and set system for plain old sleep) through Terminal commands:

sudo pmset hibernatemode 0
sudo pmset hibernatefile /dev/null
sudo rm -f /var/vm/sleepimage

`
Il the laptop does not seem to detect lid closure/opening, check that the sensor is properly connected to the motherboard. I had a similar issue on my E6220 when I 1st got it and the lid sensor was disconnected. You'll have to open up the laptop to check it out. If memory serves me right, the sensor is located in the left corner, near the SD card reader. Do check the hardware maintenance manual available off Dell's web site, it's got all instructions to dismantle and refit the laptop.

Oddly enough, it has started to work all of a sudden. I did, however, try Fn-F1 to sleep, but the computer shut down (and never booted into OS X again, had to wipe the hard disk using a Windows install CD to get the bootloader to even start after that).
