After installing Mavericks, power button does not put my iMac to sleep.

After installing OS X Mavericks, the power button does not work as before, any help?
Thanks
Victor

CT, the behavior of the power button on Mavericks (10.9.2) is not as the note (OS X Mavericks: Using the power button - Support - Apple) describe. I have to press four or five times de power button in order to put the mac to sleep.

HT6150 Single press of Power Button does not put my MacBook Pro to sleep after this update! Do I need to change anything in the settings? Any help please? Thank you!

The title says it all! After installing the new Mavericks update, I cannot put my MacBook Pro to sleep after a single press of the Power Button like before. Does it have something to do with this update or my MacBook Pro? Or do I have to change something in Settings?
Any help would be appreciated.
Thanks!

Send your opinion to Apple.
But remember that there are others.
A moment is a medieval unit of time equal to 1.5 minutes or 1/40 of an hour. This reckoning is derived from the work of Bartholomeus Anglicus, writing in 1240 that each hour was divided into four points, each point into ten moments, each moment into twelve ounces, and each ounce into 47 atoms.
In modern English it usually refers to "a short period of time",[2] the exact length remaining ambiguous.

HT201150 the new behavior of Mavericks power button does not make sense

It should go NOT to sleep when the power button is pressed...if people wants it to go to sleep just close the lid!
Instead, when the button is pressed, the dialogue box should show up asking people what to do.

Some people don't have lids.

I need to hard reset a Palm TX but the Power button does not function.

I need to hard reset my Palm TX but the Power button does not function. Is there any other way to perform the hard reset or otherwise delete all of my data?

Hi,
PowerBtn from the Canuck Software HomePage.
NOTE: This is Not a Blazer friendly download and only for downloading using a Chunky Computer thingie.
http://www.canuck-software.ca/
PowerBtn will allow you to set a HardButton to turn the TX on and off in the same fashion as the PowerButton, if you want.
This setting will remain active while 'Enable' on the PowerBtn screen is active.
The user can select 'Disable' on the PowerBtn screen.
The setting will survive a Soft Reset. (Hi PG )
If the Palm PowerButton fails completely then you will not be able to do a Hard Reset.
The PowerBtn app has a 'Hard Reset button' which you tap and after a time countdown (you can cancel in this time) it will perform a Hard Reset. This is the same as the Hard Reset app mentioned above.
The 'Enable' and 'Disable' mentioned above do not affect the 'Hard Reset button'
NOTE: PowerBtn also has a 'Program itself becomes power button' feature but I do NOT recommend you use this.
If you enable this you will not be able to change the setting or use the 'Hard Reset button' because when you Tap on the PowerBtn Icon the TX will turn Off. The only way to change the setting or use the 'Hard Reset button' would be to Delete PowerBtn then install again.
You can also turn your TX On by pushing the 5WayNav Select (middle button) to bring up the clock then double push it. The TX will stay on at the same place it was in when you turned it off, in the same way it would if you used the Power Button
All the best, woz of oz

Froze on black screen and power button does not work

my sons ipod touch is stuck on a black screen when plugged into the computer got a spinning wheel and will not connect now spinning wheel will not go away the power button does not work so can not reset it manually
any suggestions would be appreciated

- iOS: Not responding or does not turn on
Neglect the reset and when it says place the iPod in recovery mode use one of thes programs
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Power button does not react iMac Core Dua 20"

Hello,
I just purchased an iMac 20" intel Core Duo. I leave the machine to go to sleep during the night. Almost everyday when I want to start the next day my iMac does not wake-up pressing "enter", moreover the power button does not even respond. I have to unplug the power cable and after a few seconds the powerbutton can activate the Mac again. Can anybody help or should I immediately return for repairs?
Erik

Welcome to the Apple Discussions.
One question. Is your iMac a Core Duo (no longer made) or a Core 2 Duo?
Try resetting the System Management Controller;

Lenovo V570 Laptop Power Button does not work. Did I screw it up?

Hi, my Lenovo V570 keyboard recently stopped working so I took the keyboard off to reposition the cable. In the process I disconnected another cable on the motherboard (shown in the pictures below). I also cant find the black plastic piece that was holding it down.
Now not only does the keyboard not work but the power button does nothing. After research though Ifound out this laptop is notorius for having the power button go bad.
When I plug in the AC adapter I do see the battery light go on and it charges so I dont think the motherboard is bad. I
have tried every trick in the book as far as getting static out of the laptop power button (holding down power button for
certain times). I looked at the mainteneance manual for this laptop and could not figure out what the disconnected cable does. I have tried reconnecting the cable without the plastic piece but that did not work.
Is the disconnected cable responsible for this or should I order a new power button board with cable?

Hi Deziant,
Welcome to Lenovo Community!
As per the query we understood that you are facing issue with power button not working in your V570 laptop.
As per the snap shot which you have shared it looks like the black support connector is broken, you can fix this cable by using a gum, but I would suggest you to visit nearest service center to fix this issue.
Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.
Hope this helps. Do post back if issue persists!
Best regards,

After install snow leopard, ical does not show the events of some calendars

After I install snow leopard, ical does not show all the events, or simple does not show the events of some calendars that I created.
Can somebody solve this problem? Is there some update for ical?

Try the following:
1 - Go to your user account home folder, and open the library folder within it.
Look for the folder named "Calendars" and inside you might find a bunch of different folders with weird names. If they are there that means your calendars might not be lost.
2 - Look for the file "Calendar Cache". That file might be corrupted. Trash it. You may want to save a copy of it elsewhere. Once trashed, re-open ical. This should force it to rebuild its library based on those folders with weird names you saw. Your calendars should be back. Good luck

MacBook Pro will not wake, holding power button does not shut it down either

My mbpro will not wake and even holding down the power button will not shut it down. Any ideas? Thanks.

You can force quit a shut down by holding the power button for a extended amount, say ~10 sec or so.

Updated to IOS 8 and now power button does not respond and screen is frozen with apple logo.

Updated iPad to IOS 8 -- screen locked. Now screen is frozen with apple logo and the power button is not responding.
Thanks for any help!

That is normal while it is loading the update. Give it some time(shouldn't be more than 40 minutes). If not, hold the home & sleep/wake button until it is black, and then it restarts.
