Whenever my battery gets drained, my MacBook Pro turns off as if the battery was pulled out, I lose all my work when this happens.This started after I installed Snow Leopard, before, it would just go to sleep and my work is safe.

So my Macbook Pro has been working wonderfully, until recently when it runs out of battery it goes into sleep mode but when I plug in the power cord it does not do the restoring from how it was before (i don't know what its called, but its when the screen goes grey and the white bars go across until i can get back in) it does not show me anything so I have to press the power button and even then it does not show me that screen it just reboots (i don't hold it in but just press it normally like when booting it up) Then when it is booted the date and time are reset and the Wi-fi does not work. I have to reset the clock and it then works fine.

Is it strange that my MacBook now just shuts down when it runs out of battery instead of just going into sleep mode? It's about two weeks old now. It used to go into sleep mode, but now it just shuts down once the battery is down. Also, I had the most wonderful experience with Apple. My first macbook (three weeks ago) had a small chip on the screen. When I finally noticed it, I thought it was a large piece of dust so it wasn't too terrible. I tried to exchange it at the local store where I purchased it, but it had already been four days and I had cut out the UPC for the printer and ipod rebate the day before and sent it out. So they recommended that I go see a mac genius and see if I can get the screen replaced because I could no longer exchange it or return it (risk losing my rebates).
So, a bit upset that I was too prompt about getting the rebates in, I scheduled an appointment with a genius. When I spoke to him, he just went to the back and got the manager. The manager said instead fixing the screen, he'd liked to give me a new macbook and instant reimbursement for the ipod and printer! (the rebates I sent in will be rejected since the mac has been returned). The new macbook I noticed has a much louder superdrive seems to be working hard every time the computer wakes up and when I open it, but that definitely beats a chip on the screen. But now it doesn't go to sleep after the battery gets low, but instead shuts off.
I have my mbp just 3 weeks old and I tried to calibrate the battery just few hrs ago. I continuously used my mbp until the battery level reached to 2% (the warning message showed when it was 6%). Just then I had to receive a phone call. When I was busy talking, I noticed that the mbp has gone to sleep mode but when I returned (2-3 mins later), I found it shut down. Well, I think it should have remained to sleep mode but it didn't.
Then after an hour I connected the power cord and switched on and noticed a progress bar which I saw for the first time. I have been charging it for 40-50 mins, now. Also the health of my battery keeps fluctuating between 95-100 %. istat shows this. Is this normal? So what I want to know is, Is this normal for mbp to shut down when the battery reach that low? OR there is some problem in my MBP?

Just wondering if anyone has ever encountered this or if any experts out there know of the issue.I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.
I've got a Late 2009 Mac Mini running Snow Leopard Server. Occasionally, it takes me awhile to restart after updates, so this could be due to the most recent update or possibly the combination of the last two...
I went into my office, saw that there was a Safari update and decided to let it do its thing. When I came back 30 minutes later, my machine was off. I turned my machine back on, got the gray Apple screen with the spinning cog and the progress indicator for the update. A little over 10% through, the progress indicator reset. No biggie, I figured. Second time it got to the same point, it just shut down. Nada. When I restart, it does the same thing.

My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I am having trouble starting my 21" iMac running Snow Leopard after I had shared the HD with my MB-Pro. I had removed the "everyone - Read Only" rights on the HD (on the iMac) and opened sharing so my MB could attach to it. Grey Apple Logo and progress circle upon startup now.Can changing these rights cause the system to not boot? I can go into single user mode but I am not sure what to do then.

I've usually in all my year with Mac not had my drives sleep. I note now that when my drives awake one of the fans is spinning faster than normal. Just a little nothing crazy and then it slows to normal. Â
Is this the sound of a problem fan or something on my motherboard or something? Â
Should I do a PRAM reset? or whatever it's called these days? Running OSX 1.6.8Â

Shortly after updating:
Safari (to 7.0.6)
Java (to version 7 update 67)
Pages (5.2.2, which has "An error has occurred" note in the purchases section of my App Store application)
Keynote (6.2.2)
Numbers (also has "An error has occurred" note in the "Purchases section" of my App Store application, and while it shows "installed" in same section, Numbers does not appear on the recently updated list in the "Updates" section)
and iMovie (10.0.5)
I also recall an Adobe update occurring (Macromedia?).Â
I began experiencing slow wake-from-sleep behavior. More recently, I have been getting "out of application memory" dialogs upon waking from sleep. There have also been a couple instances where the computer would not wake and had to be restarted. At one point, without having gotten the "out of application memory" dialog, I did note that virtual memory had ballooned to over 14 GB. That stayed like that until I logged out and logged back in.Â
This behavior seems to be specific to a user account (did not repeat when logged in as admin for one overnight test, but haven't tried an all day admin login).
I've tried uninstalling and reinstalling BOINC, as well as removing an Adobe Resource Synchronizer app from the user login items (given the recent Adobe update, and having read that said item could cause trouble).Â
So, I'm not sure how to proceed beyond offering the reports below:

my new white macbook runs slower on battery that when it is plugged in. The most noticeable thing is that the applications folder loads slower and is laggy to scroll in.
Unchecking put harddrive to sleep when possible did not fix the problem.
Any ideas or is it supposed to run slower to save battery?
I have a G5 (Power PC, g5, Dual 1.8 GHZ with 1.25 GB SDRAM, and Mac OS X 10.4.10-phew!) and I recently: added more USB ports using a PCI card, and purchased a non-Apple 22" widescreen display.
Prior to adding USB ports, I was using a hub that ran off its own power source, and used a Samsung 19" monitor.
My situation now: everything starts up fine, but ultimately the fan will kick in at SUPER HIGH and won't stop. I can put my Mac to sleep--which stops the fan noise--but then it won't wake up.
I have run the Apple Hardware test and everything checks out OK. I've also reset the SMU according to directions from this forum; AND I've vacuumed out all the dust bunnies.
The fan runs so loud and so high it sounds like it's an airplane that's about to take off.
Short of bringing in my Mac to a technician, can you recommend anything? My Mac has been glitch free up until now.

I've got an early 2008 Macbook Pro and, recently, I've noticed that the fan (fans?) begins running from the moment the computer is powered-up. iStat tells me that both fans are running at about 2000 rpms, though I only hear a slight whoosing noise from the left side. I don't remember the fan running constantly, and I have noticed that my battery life seems worse than normal recently. Is this normal, and something I just haven't noticed until recently?

Late 2008 MacBook, online via WiFi. Since upgrading to 10.6, about 50% of the time I wake the lappy, apps cannot resolve hostnames. Ping by IP and dig to resolve names works on the command line. However, no apps can get DNS. Safari and Firefox report "offline" mode. Anyone else see this? A reboot is the only fix I've found, and that's a pain.

View 5 Replies View RelatedI have an ibook G4 14" 1.42ghz.I have it plugged into a power adapter almost always. It has been plugged in in both instances/I recently put it to sleep and when I return anywhere from 15 minutes to a couple hours it is shut down. I have a heck of a time getting it to power on. It took me several times, anywhere from 3-6 times to get it to turn on.
When I turn it on it goes through the usual loading procedures and after loading a window pops up saying the date and time are wrong and could cause applications to act erratically. The date ends up being 1969 and sometimes the time is wrong.
I have fixed the date and it still happens.
I don't know if this has affected or led to this but my battery has been shot for a couple months now and occasionally (probably 1-2 times a day) the power adapter (a cheap copy of apple's) would become unplugged from the laptop prompting the message stating you are on reserve battery and that the computer will go to sleep soon.
Does anyone know what is causing this? How much would it cost to fix it?
My daughter's macbook pro is supposed to sleep when the lid is closed but it usually shuts off the hard drive instead. She has a 15", 2010 model with the latest software and updates.
View 5 Replies View RelatedMy MacBook Pro will not go to sleep after installing Snow Leopard. It WILL go to sleep if I close the lid; however, if I have it sit open for 15 minutes, it won't go to sleep. It attempts to sleep, but instead the screen will just go black for less than a second. It's just like a flash of black, and then the screen goes back to normal. It simply won't sleep.

Now I tried pmset with no success like so: sudo pmset -a hibernatemode 0
Why does snow leopard take so long to go to sleep, does anyone else have this issue? Is there anything else i could try to fix it. It says hibernatemode is 0 in pmset info table.
It takes 10.6.1 35 seconds to go to sleep. Anyone else having issues like this? It takes in about a second. I could shutdown faster than it takes to sleep but damn.
