Will not sleep when closing lid
The noted Macbook will sleep automatically per settings in System Preferences and when > Sleep is selected. However, when the lid is closed it will not sleep and the back-lit Apple logo on the cover stays lit.
I've tried creating a new user - issue remains. Tried a clean install of Mavericks - issue remains.
This Macbook recently received a new screen (from iFixit) which in all other respects works fine, and there were no issues during installation.
Is this a hardware or software issue? Any pointers for further differential diagnosis are welcomed.
