MacBook Not Sleeping When Closing Lid

i have noticed mac has not been sleeping when close lid. used to, close lid , throw in bag. now, passcode required immediately, screen displays desktop (or whatever had when closed it) before can opened, showing never went sleep. if go menu > sleep... however, mac sleep properly, assume. ask password way, making me assume went sleep.

don't know if issue related el capitan, did not before. know because have downloaded software such nosleep , caffeine keep mac sleeping when downloading, uploading, rendering, etc. long periods of time , want mac stay awake.

uninstalled both caffeine , nosleep see if problem, no luck. restored default settings in energy saver preferences. did smc reset no avail.

have 90+ gb of "other" space on mac, possible there remnant file somewhere keeping mac sleeping? (i planning on doing clean install of el capitan when have time next weekend, hopefully...)

there problem magnetic sensor responsible detecting when lid closed , when sleeps?



appreciated!

command used in article (pmset -g assertions) still works in yosemite (i haven't upgraded el capitan yet). see you're running el capitan; still works you.

following instructions found out that, in case, internet sharing keeping mac awake.

edit: wait minute... article mentions internet sharing specifically, maybe gleaned internet sharing culprit article's first paragraph, , not running pmset -g assertions. man, i'm getting unreliable.
