Software :: System Not Exiting Sleep Mode / Kicks Back Into Sleep Mode

Dec 29, 2009

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.

The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.

How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

Mac Mini :: System Keeps Going To Sleep Mode / Preferences Are Set To Never Sleep

Aug 10, 2009

I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

MacBook :: System Not Go To Sleep Mode Immediately

Dec 11, 2009

My MacBook does not sleep immediately, I have already tried removing safe sleep and it gives me no effect. It is not a hardware problem as my Windows Vista on the Machine sleeps just how I would like it. For info, the Hard Drive that is in it (320GB WD Scorpio Black) was used in an EFI Hackintosh install for my MSI Wind (but EFI installs do not modify the main operating system so I do not know what the heck is causing this)? By the way, the MacBook is custom, made by me. I built it out of three dead MacBooks.

One Black Core duo which was stepped on and had a broken screen and hinges which gave me:
Only working Logic board of the Pack (2.0GHZ Core Duo) I paid 140$ for this one
2 512MB sticks (Removed one and added a 1GB Stick, yes I know matched pairs, gonna find another 1GB soon)
Bottom case.
Top lid
Half the keys for the keyboard.

The Second MacBook Free:
2.0GHZ Core Duo white gave me with coffee spilled on it
Top case with trackpad, and half of the keys
Bezel
Hinges
Screen
other screws etc.
Fan (The one inside was going clack clack clack)

One 2.2GHZ Core 2 Duo which a dog peed on, Free for getting data off of:
DVD-R Drive one that was in it wouldn't eject
Sleep Light, the one that was there originally was borked and did not light, and IR did not work. Now it does
alternative screen with no pressure marks like the one I have now but one noticeable 1/2 inch scratch.
Various screws.

I am yet to finish it. I am still prototyping the new top screen assembly using the Black lid, a red apple, and the screen with a scratch on it, and the bezel from the 2.2GHZ which is really beat up. The current top assembly is straight from the 2.0GHZ White. Here's a pic of it in it's current state.

MacBook Pro :: Do I Require AC Adapter To Plug In When System Is In Sleep Mode

Sep 13, 2010

1) If my MacBook Pro is fully changed and I plan to put it to sleep mode, do I still need to let AC adapter plug in?2) Let the computer to sleep or turn off is better when I don't use it?3) What's the normal "Fully Changed Capacity"? Because I saw it changed from time to time when I check in "Apple system profiler"?

Mac Pro :: Drive Causes System To Reboot After Sleep Mode

Jan 31, 2008

I have resolved my MacPro sleep issue by removing the Seagate 320GB stock drive. For whatever reason, if that drive is plugged in, it reboots my MacPro when waking from sleep. I had setup 2 WD 500GB drives in RAID 0 as my boot volume and this was configured with Windows XP Pro for other uses.

OS X :: System Gets Slow After Sleep Mode / Unresponsive To My Commands?

Sep 8, 2009

Background info:
A few weeks ago I upgraded from a regular macbook to a brand new macbook pro 2.66 ghz. I replaced the hard drive right away with a 500gb one (had it done by apple). So my machine runs snow leopard now, I used the data transfer mode to basicly copy the data and apps from my old macbook to the new MBP.

The "problem"
It all worked fine and smooth until a week ago ...For a week now I have a problem that really concerns me. Whenever I open my laptop from a sleep mode he gets really slow and unresponsive to my commands. Its like its crashing, all I can do to get out of this is a hard reboot.

However .. during a reboot OR a cold bootup the MBP gets stuck in the grey screen with only the apple logo .. after a minute or 3 it will start loading but it will never reach the login screen... The strange thing is that when I do reboot it over and over again .. it eventually will boot normally and when it does the MBP runs fine .. until I turn it off or put it in sleep mode .. then the nightmare will start again.

What I have done

I personally suspects the Hard Drive to be the culprit, I get the feeling that the Hard Drive is having trouble starting up or getting out of sleep mode. I am not sure tough.
I have done the following:

- Disc Utility (gives no errors)
- Booting up in terminal and run Disc Utility there (repaired a volume issue)

Could this be a leopard issue? I actually can't remember if this issue happened after the last macOS update or not ..I never had a problem with my iBook and Macbook so I have little experience on troubleshooting. So I hope you more technical experienced users can give me some tips on what to do here.

Software :: Middle Of Using An App, Browsing Web Page - System Into Sleep Mode And Will Not Wake?

Jun 18, 2009

I can be in the middle of using an application, browsing a web-page, or basically any type of function when it will put itself into sleep mode. When this happens, I cannot get it to "wake up". I have to disconnect it from the power source, turn it over and remove the battery, wait a few seconds, then hit the power button, put the battery back in, then restart it. This is the only way I have found that will get it to come back to life. I don't like doing it, but I really don't see what other options I have.

MacBook Pro :: Cannot Boot Into Recovery Mode After Installing New HD

Jun 17, 2014

I just installed the Samsung EVO SDD in my Macbook Pro (mid-2009). I want to get into Startup Manager or Recovery Mode to restore my data. My main goal is to use my Time Capsule as my recovery disk.  

So far I am getting a folder with a question mark everytime I boot into Recovery Mode (Cmd + R) and a white screen with the mouse cursor when I boot into Statup Manager (Option key). My last resort is to re-install my old HD and use a SATA cable.

MacBook Pro :: Can't Access Recovery Mode To Erase HD

Aug 27, 2014

I can not access the recovery mode. If I reset my MAC while holding "command-R" it just brings me to the desktop. If I reset holding "option" it will show me the HD but no recovery option. If I access the disk recovery from the desktop, any option to erase HD is greyed out. I have done all system updates and I can't access the internet recovery option either....

I'm planning on selling my Macbook tomorrow!

MacBook Pro :: WiFi Not Detected In Internet Recovery Mode

Aug 30, 2014

I am trying to reinstall the OS, and got into Internet Recovery mode, and got a list of Wifi networks to select, but my own was not one of them.  I even clicked "Other" (or something like that) to enter the SSID and passphrase, but that was rejected.  I am now piggy-backing on a nearby wifi, with all the risks that entails.  Why won't my Mac see my own Wifi?  (Everything else in the house sees "five bars", including my wife's Macbook Air and my iPhone.)

OS X :: Unable To Play Itunes / System Goes Into Sleep Mode While Playing Itunes

Sep 1, 2010

I recently upgraded my system HDD to an SSD with a new install of OSX 10.6.4 and mimicked the settings I had on my previous set up to replicate it. however, when for example I was using iTunes to play music the screen saver would come on and a short time later the system would pause iTunes and goes into Sleep mode.

my previous install never did that so I'm not sure if its because of the SSD and it not being mechanical it doesnt recognize it accessing or seeking 'per se' because regardless of unchecking "Put hard disks to sleep when possible" it still does it. here is an image of energy saver settings; btw I had the system plugged into and still went into sleep mode when iTunes was playing and even other media formats such as Video in iTunes or VLC.

OS X V10.7 Lion :: Macbook Pro Freezes At Logo Screen, No Safe Nor Recovery Mode?

Jun 5, 2012

my macbook pro today started to freeze at logo scrren. I tried to start it up in both safe and recovery modes but it doesn't work either. I got the system to start in safe mode only once and the scrren looked like in the attached image.When I tried printing the screen instead of taking a photo with my mobile, the image appeared to be normal (without those noisy rectangles), but it wasnt. Then itried restarting but it's been impossible. As i said i tried booting on safe and recovery modes but the circle below the apple logo appèars and then it freezes again. I read about aproblem with the graphic card similar to mine in earlier models, I don`t know if it is the same problem.

It is completly idiotic and totaly unsafe and an easy ways for f.i thiefs to wipe the computer for data.
