I have inadvertently left my 2011 MBP running with a processor intensive music app running. The battery ran out before i realised.. When i attached the power lead to charge it, the computer automatically restarted without even pressing the power button. The computer had not entered safe sleep mode, presumably because my music software was still running.Â
Since then the computer will not ever enter safe sleep when the power runs down. The battery just cuts out each time when it drops to less than 5%, it does not run out at 0% like it usually does. if it is the logic board battery because i have had this issue a couple of times before but it rectified itself after a few days. I have checked that safe sleep is enabled which it is, but the computer just cuts out before safe sleep kicks in.
Info:
MacBook Pro (13-inch Early 2011), OS X Mountain Lion (10.8.5)
Basically, all the general information about it.. I've been reading people's problems and I see this all the time, and I'm totally confused on what it.
I have already covered these steps:1. I have tried a safe boot. 2. I have tried to reset the NVRAM and the PRAM.3. I have tried to reinstall OSX from the Install Disk.4. I have tried to repair the HD and tried to repair permissions using the Disk Utility. he issue started out as the flashing Apple/Question Mark Folder/"No" sign. I attempted to follow the steps on the Mac Support Forums (ones listed above) and the issue developed into the picture shown.
recently i zapped my Pram becuase i was having trouble with a external screen but when I turned it on again the screen when to the grey screen with the apple logo and spinning gear but after 2 hours of wating the screen is still the same. What can i do to get back onto my mac?
Recently my MacBook Air has failed to wake from sleep mode. The Apple illuminates on the back of the screen casing, but neither the screen nor hard drive actually wakes up. The only way I'm able to use the computer is by forcing a PRAM reset on restart (command-option-P-R). I've had to do this several times in the last two weeks. Â
The only things about my MacBook Air that have changed in that time period are:Â
- I installed OS Yosemite
- I installed and ran Sophos Anti-VirusÂ
(The latter was installed to counteract a problem that I was having with my email address having been spoofed and sending spam. Sophos found two bits of malware in email data files and "cleaned" them up.) Â
Today I noticed that my mid 2010 MBP is not automatically sleeping. I ran Apple's extended hardware test, along with TechTools Pro 5 from AppleCare disk. Both passed. Reset the SMC and PRAM. I'm still not able to auto sleep. Is there a way to see what exactly is causing my computer to not automatically sleep? Console messages or something?
I recently purchased a 13" 2.26 stock macbook. It's perfect, screen is good (no scrolling issues or purple blues) with no dead pixels, no slanted keys, and no scratches.
I updated the firmware that addresses the SATA 1.5 issue. After the update, I reset PRAM. I held down the buttons till I heard the second or third startup bong.
Here is where it gets funny.
Now, when I reboot or start up my computer, the start up noise is loud. Even with headphones plugged in and also the volume turned to its lowest setting (even with volume turned off). Eventually, to control the startup noise, I had to install the startupsound program in my system prefs as mentioned on other threads and that has seemed to control the startup sound.
I was wondering, if by resetting the PRAM if I have harmed my computer in any way. Should I be worried about deeper issues with my computer since the startup sound was not previously being affected by reducing the volume to zero with headphones plugged in?
I have tried SMC and PRAM resets, and the issue has not been resolved. My magsafe is lit up with a bright green led. Battery status is "Not Charging." When I unplug the magsafe, the system immediately shuts down. Battery is brand new with only 2 cycles. While I can use the laptop with power connected, this is an issue that needs to be corrected asap, as I use this computer for performances consistently and if the power cord gets removed, I'm not in a good place.
My macbook pro won't boot past the grey screen, I've tried reseting PRam, running fsck from single user etc to no avail. All signs would point towards a hard disk failure, but the curious thing is that it sometimes mounts in disk utility when booting from the install CD, so theres a little life left in it yet! I have fairly recent backups of most of my files, but there are a couple I've been working on in the past few days that won't be backed up. So my question is this - is it possible to copy files from my mac HD onto a external drive through the terminal/disk utility while booting from the CD.
I am running Mac OS Lion (10.7.3) on a 8-core Mac Pro. As I turned on my mac this morning, I found out that I was unable to use my wireless mouse, and also that I couldn't open my bluetooth settings. Apparently, the entire module disappeared from the System Preferences, and when I went to one of the articles on here, I saw that I'm supposed to reset my PRAM and SMC in order to make my bluetooth work again. The problem is, that I don't know what PRAM or SMC are, nor do I know how to reset them.
I have a 17" Powerbook G4 1.5 GHZ. I lost all sound from one moment to the next. System preferences says Audio output Headphones however no sound from Headphones either. I tried to reset my PRAM, however when I hold down "Option" "Command" "r" and "P" the computer won't restart. The hard drive seems to be stuck at this point and won't go any further. I went to the Apple store and the Genius lost patience and said we should send it out. (I'd rather not)
I have also reset the PMU
Everything else works fine.
I've looked at several other threads and post. Everyone with a sound problem seems to be able to get it resolved with a PRAM reset. However I find nothing on my the problem of not being able to reset..
I have tried two different brands of blank CDR in my drive and both times, they fail to mount and in Disk Utility, show up as Sony DVDs (neither of them is a Sony or a DVD), but not writable. I have no problem with media that already has content. I've tried resetting PRAM, but nothing else yet.
I tried the SMC & PRAM reset. Now, there is a delay in my keyboard and mouse. For example as I am writing this, as I type, I am observing a ~1/4 sec delay between me pressing a key and the GUI registering it. The same with the mouse. I can click-and-hold over say File and move it up and down over subsequent menu items and it the GUI doesn't highlight the menu item unless I slow down the movement.
Can someone explain to me why resetting PRAM on a machine has any effect whatsoever for networking issues? ie; self assigned ip etc. I have noticed this is a common troubleshooting step that a lot of people are recommending for issues related to networking.
Updated to OS X Mavericks last week. Ever since, it has been experiencing boot problems. Â
- If I restart my Macbook Pro (2011 13", lowest model), it will sit at the grey screen with apple logo and spinning grey wheel forever. I notice that my HDD is NOT running (no clicking / writing sounds)Â
- If I restart with a PRAM reset or holding down option to select Macintosh HD boot, the hard drive starts to run (I can hear it) and it boots successfully... it takes 5+ minutes to boot up. The grey screen with apple logo is presented on my screen for about 4 minutes, then the login screen shows up but I cannot move my mouse or select a login user for 30 seconds. After this, I can log in succesfully.Â
I understand the steps needed, but how many times should I reset the PRAM and how many times should I here the startup sound (in total) before releasing the buttons?
I attempted to reset the PRAM on my macpro running snow leopard this morning, by rebooting and holding cmd-option-p-r until the apple logo appeared, at which point I released and then machine then rebooted a second time. I went back to the computer about an hour later and it was stuck on the apple logo screen, with no sounds coming from the CPU. I did a hard reboot by holding down the power key and it started up fine. I've never reset the pram before and so I didn't know what I should expect as far as the process being successful, but after an hour stuck on the apple logo I figured it got stuck on something.
I have a G4 MDD Dual 1.42ghz, When I hold down the Command-Option-P-R keys during restart it doesnt do anything. It keeps going straight to the gray screen and starts up. I dont know what to do. Anyone know whats the problem? Also my computer cant wake up from sleep or even go to sleep all the way.
I lost the startup tone a couple days ago. I repaired permissions, did an SMC and PRAM reset and it makes the tone while doing the PRAM reset but the next time you turn it on it doesn't make a sound.
So I contacted Apple this morning regarding the LCD Backlight Bleed on my iMac (24", early 2008, 2.8 ghz) They made me reset the PRAM, which I figured wouldn't work, and the issue is still there.
They say it'll have to go in for servicing, and I live nowhere near an Apple Store, so they gave me the location of the nearest London Drugs. Am I going to get the same quality of service as I would from an Apple Store? And what is the exact process that they use, do they just replace it with a new LCD?Also, he said that it will be covered under Applecare unless it is ruled as accidental damage, he said that much of the time, the issue is caused by pressure on the back of the case, and that if that was the case, it wouldn't be covered.I can't really see how this would cause it, and I haven't ever put any pressure or anything on the back, but i did buy the iMac used, what are the chances of this being ruled accidental damage?I have the bleed in all four corners of the screen, if that makes any difference.
Where do you sit on the whole Genie Effect vs Scale Effect war that's been raging for the last 8 years? Whilst the Genie wowed me the first time I saw it, I chose Scale Effect pretty much as soon as I got OSX, preferring performance over prettiness. Now, years later, when I occasionally catch it on other peeps machines I think it just looks... tacky. I wonder how many people on here still have it switched on?
It has been a while i havnt used my MacBook Air. I forgot my passwords to enter.How do I completely reset my computer so that passwords are disabled or just reset?
