OS X Mavericks :: Power Nap Not Working On New MBP
Sep 11, 2014
I got the newest 15" MBP and I'm trying to get power nap to work, but as far as I can tell, it does not work yet.Â
I enabled power nap both when the laptop is connected to power and on battery, but every morning when I look in iTunes, my podcasts have not been updated since last time i closed the lid.Â
I also tried to start downloading a podcast and close the lid, and when I open it again, the podcast has not progressed in the downloading.Â
Info:
MacBook Pro with Retina display, OS X Mavericks (10.9.4)
i've recently ask in the forum for expanding my G5 and G4, because the DVD-RW stop working on both. I've bought a Pioneer DVR-112 and install it on the G4 (under panther). Startup the mac and it was there on the system profiler, but when i'd tryed to open the tray, it couldn't go out because it was getting jammed bye the mac tower (some plastic thinggis around the drive hole), so i've notice that the previous DVD-RW didn't had the front part on the drive that says DVD-RW and all the stuff. So, shutdown the mac and removed the drive to see what it can be done. Installed again and now the mac don't recognize the drive.

I have an iMac 2.4Ghz 24" about 18 months old. After a visitor's mains powered hard drive (which was later shown to be already faulty!) was connected I lost the power to the USB bus inside the iMac. I can still use devices that need power with an USB port expander but this is far from ideal. USB data is working fine as is the firewire port. Simply the power to the USB. I have reset the PRAM but not yet reset the Power Management Unit. I assume there is no physical fuse for the USB power internally as I have not seen a reference to one anywhere. Should I reset the PMU?
Are the USB and their power integral to the motherboard? On start up I get the error message: "USB Over Current Notice. A USB device is currently drawing too much power. The hub it is attached to will be deactivated." I get this error message even when nothing not even keyboard is plugged in (so its not that faulty keyboard error). There really is no power at the USB ports - but data is working
I have a power Mac g4 which is about 11 years old which is having issues.Replacing the battery was a big solution, but since I did this yesterday, I am getting Kernel screens and monitor blackouts, jumpy cursors and the delete key not working.I have just reinstalled the OS and updated the software, but the delete key still isn't working. The mouse seems normal now, and so far the monitor will come back when it is asleep, instead of going black and staying that way.But the delete key still isn't deleting.
I have Skypes working on my G-5 and have added Macam and a Logic Tech Chat camera. The camera works well on my screen but is not seen by others when I contact them. I just get the small black screen in the Skypes window. Is ther another piece of software I need other than Macam for Skypes connection or.I did get a message on screen that Skypes had connected to my camera.

3 times in the last week, my 400 & 800 firewire ports are not working. I am using a firewire hub with several external drives. I unplug everything, reboot and then they work. anyone know what is going on?
Both my firewire ports are not working. No signal or connection with external hard drive or video camera. Firewire does not appear under Network Status and is grayed out under Network Port Configurations.
My Macbook Was On And Working And I Tried To Hit The Power Button To Turn The Macbook Off And It Would Not Work....so I Shut It Down Using Computer Shut Down Under The Apple ....now It Will Not Turn Back On......it Has To Be The Power Button Itself....is There Any Where I Could Buy A Replacement Power Button? And Is There Any Other Way To Get It To Turn On Without Using The Power Button?
I juust was given a nice Logitech web cam for my Power Mac G4 and found out it doesn't work. I have a drivers disk but it's only for Windows. Anyone know how to get it to work?
As usual, whilst claiming green credentials, the information Apple gives regarding power use is minimal and vague to the point of being meaningless .The only figures they quote are:- Maximum continuous use 205w (21.5") and 310w (27") What exactly does maximum continuous use mean ?Â
a. When the machine is switched on but not doing anythingÂ
b. Working at general office tasksÂ
c. Working flat out transcoding video etc.Â
Which of these is it? Or is it all 3? Does it use more power when performing harder tasks? If so, what power is used under scenarios a and b? Finally, how much power is used in sleep mode?

I have an old AGP graphics G4 power mac. Keyboard and mouse are not working and I get no signal to the monitor. Is my logic board fried, or could it be something else?
I followed all the instructions in the previous threads and unstalled my older version on flash. Then installed PPC Mac Flash version 10.1.102.64 and it says installation complete but when I go to test it nothing works. I tried restarting and uninstalling and starting over. I keep getting installation complete but still no go. I checked all my soft updates and everything looks good.
I'm trying to fix my mother-in-law PowerMac G4.   She doesn't remember the admin password and I've been trying to reboot from the install cd. However, after pushing the "c" button. Nothing happens and it boots normally.Â
I have a new power cord for my MacBook Pro. I plug it into the laptop, it turns green for about one second, then goes to orange. It doesn't show in the battery icon that the battery is charging, but if I turn the laptop over and look at the battery, the green indicators on the battery are blinjking like it is charging. I keep getting the "now running on reserve power" error. Now, just two minutes later, all of a sudden the screen gets brighter and the battery life indicator on the screen shows that the battery is at 74%! How could I be running on reserve power at 4% one minute and be at 74% the next?
using a g5 intel running 0s 10.4.11 and my keyboard has stopped working ,it doesn't work while i am on the desktop , so using shortcut keys and changing file names etc.

If so, how do I avoid frying my macbook air and other electrics, like my iPhone, camera battery, and shaver. ?had that built in or something, so as to just buy a weird 3-prong adapter...I saw the set of adapters available on Apple's site, but those would then only work for my laptop charger. I'm sure I could find the UK 3-prong to US-adapter... but what about voltage? I've never traveled overseas and had to convert power before
I have a four-year-old 17� inch Powerbook that is in need of some restoration. The optical drive does not work, the battery lasts all of 3 minutes when its not plugged in and the firewire ports don�t work. So since the optical drive and firewire ports are unusable I cannot install Leopard, which I would like to do. Also disk utility says the hard drive needs permissions repaired but I would need to insert the install disk to fix them and since I don�t have disk warrior or drive genius already installed it seems like a problem is going to happen soon.
I've been experiencing the following problem with my late 2007 MacBook Pro: I can't use it on batteries. As soon as I disconnect power supply, it works for 10-15 minutes and switches off. Not sleeps, but suddenly turns off completely. The system battery indicator drops by about 10% (showing 85-90% battery charged), whereas 4 out of 5 LEDs are lit on the battery itself. After such a sunned switch-off, I'm not able to start again the laptop - it doesn't react on Power On button - like the battery wasn't inserted at all. Right after I plug on power supply back again, everything gets back to normal and I can use it normally, but still only if it's connected to the electricity.
Ok. so my MBP was working 2 days ago and I went to Fry's to replace the HD with a 640GB model thinking larger storage - win. Replaced in and the orange ribbon cable got disconnected between the keyboard and the logic board. Went frantic and after a visit to the Apple Genius, they plugged it back and thought i was fine. Nope, and now the unit won't turn on. Plugged it in and got the green light and battery charges, but the MBP won't power on. I made sure the HD was plugged in securely, the orange ribbon connected fine, and the power button cable was secure. The drive worked fine as I did a superduper transfer of the old data to the new drive the night before the crisis and it worked fine.
After 1.5 years of use, my hard drive suddenly failed. This was later confirmed by Apple Genius Bar. So I purchase a new SSD from OWC which was instructed to be compatible with my laptop model (MBP 13" early 2011). It arrived today and I did the installation carefully and successfully. However, after putting the back panel back in place I was unable to power up my laptop.
It was as if the power button is not working. Then I opened up the back panel one more time to realise that every time I click the power button (turn on), the fan started running, this can only be stopped by pressing the power button and held it (turn off). I tried placing my old hard drive and it doesn't work as well. I tried reset the SMC by holding power-shift-option but same result.
The firewire port on the front of my machine is bad. I can't transfer any kind of data using it. The port on the back as well as all USB ports work fine. Would this need a complete motherboard replacement? Would it even be worth doing? Could I build a dual processing machine or buy one cheaper?
Starting this morning an X has appeared over my battery icon. When I click the icon is says no battery available. When I check the system profiler it says no battery installed. When I click the button on the battery all 6 lights turn on. I have read similar posts to this that say when they unplug the power supply the mac turns off in a few minutes, mine however will stay on the same amount of time as if the battery was charged. I'm surprised that this happened because I bought a new battery 3 months ago because the original one short circuited when my hard drive went last summer.
I had to have the power supply constantly plugged in if I was using the computer. I tried shutting down the computer, removing the battery and restarting and that worked. However when I shut down, unplugged the power supply and tried to restart, it did not turn on. I'm hoping there is a solution as I use my laptop on the road often and not being able to turn it on without the power supply is a real inconvenience.
I spilt some water over my unibody MacBook Pro about 36 hours ago. It was dark, and as the screen didn't respond I assumed that it had shut down, but on closer examination the next morning (after turning it upside down) I found that it was still running. I shut it off then. There didn't seem to be much water inside the MBP, so I tried turning it on just now. It made all the right start-up noises, but nothing on the screen (the Apple logo also wasn't illuminated). I forced it to shut down again right after.
I'm not near a service centre at the moment, so am wondering if I should just wait a few more days, or get it sent in right away? I guess the fact that it starts-up is encouraging, so hopefully the damage is just limited to something connected to the monitor. No water was split over the LCD itself, but I'm guessing some may have entered at the back of the unit, where it connects to the main body. I did almost the exact same thing to my 3yo MB about 2 months ago, and it started working after about 3 days. I guess I should be more careful about what I put near my computer in future!
I noticed yesterday that my 23" ACD, which I use as a secondary monitor, power light was going on and off even though the monitor appeared to be working fine.
When I put the computer to sleep the monitor stayed on (I could see the backlight lighting up the screen even though it was black).
Now the power light stays off, the monitor works, but I can't adjust the brightness and the power button doesn't work. When I go the System Preferences and Displays there is no brightness slider available for the 23".
I have tried unplugging it, rebooting the computer etc, and even booting up in my backup of Leopard (I usually use Snow Leopard) but it doesn't change anything. Anyone else had this issue? I did have a power cut the other day, but I don't know how that could have affected it.
I was charging my macbook. It was charging when I left, upon my return, after about 30 minutes, I found that the light was no longer green. There was no light on at all. I tried restarting multiple times. There are no stuck prongs in my power cord. I tried different outlets. I tested the outlet to verify it worked. My computer will charge fine with other power cords, but just not the one I want it to use? Is there anything else I can try before purchasing a new cord?
