Since the new D54250WYK1 NUC has the built in IR, Here is a great tip that I found on the internet which changes the SLEEP to SHUTDOWN for windows 7 users. The typical power button on the nuc will put the PC to sleep. I like to shut down the unit to a closed state vs sleep.
Copy Paste from another site.
Hi, I've found a possible solution.
Problem:
Control Panel\All Control Panel Items\Power Options\Change when the computer sleeps\Change advanced power settings\Power buttons and lid\Sleep button action\Setting:
don't have the "Shut Down" option.
Possible solution:
Run: Regedit
Open: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\PowerSettings
Then, click on every folder until you find one folder that contains the "FriendlyName": @%SystemRoot%\system32\powrprof.dll,-251,Power buttons settings
mine is the folder: 4f971e89-eebd-4455-a8de-9e59040e7347
when you find it, open it and search for the forder that contais the "FriendlyName": @%SystemRoot%\system32\powrprof.dll,-255,sleep button action
mine is the folder: 96996bc0-ad50-47ec-923b-6f41874dd9eb
then, open the forlder: DefaultPowerSchemeValues
you will find 3 folders. For each folder you will have 3 "files". You need to change the value of the files (in every one of the 3 folders):
AcSettingIndex: to 3 (it is by default to 1)
DcSettingIndex: to 3 (it is by default to 1)
Then, you go back to the Control Panel:
Control Panel\All Control Panel Items\Power Options\Change when the computer sleeps\
and click on: Restore default settings for this plan
and its done!!
hope this helps... good luck.
Thanks,
