MacBook Pro :: Random Shutdown On Battery With High Cpu Load
Mar 19, 2012
I've been having an issue with my Macbook Pro, it keeps turning off while on battery power while I am playing a game (Starcraft II) despite having sufficent charge remaining. It won't turn back on until I plug it back in. Usually when I turn it back on the time and date are reset and the password to my wifi has to be rentered. The most recent time this happened after I plugged it back in the battery still had 79% charge remaining. I've tried recalibrating the battery and resetting the SMC both which did not solve the problem. The system report states that the battery's condition is normal and I ran a hardware test which also came back normal.

Has anyone had the following problem? My Macbook Pro is 2.5 years old and has recently been shutting down for no apparent reason while plugged and unplugged into the power adapter. I went to the Apple store a few weeks ago for an issue where the Macbook Pro would not turn back on at all. They had to replace the logic board. But after that, I now have the problem of the shutdowns. I went to the Apple store and got a new power adapter because mine was broken. I thought that would be the problem, but it isn't. I also recently reinstalled my operating system and the problem is still occurring. Does anyone have any advice? My laptop is a 2.2 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM. My battery is in 'poor' condition, but according to the Apple experts, the battery has nothing to do with this issue.

I've been getting these high-pitched chirps (beeps? cheeps?) emanating from the upper left quadrant of the keyboard. They seem to happen when I'm doing some heavy photo processing or such. They're not the chirps that have been reported with some MB and MBP on booting up. I've had them now for months, and while I don't think they've got much worse, they've not gone away. I can't seem to make them happen, either.
I've called in to Apple (Applecare runs out in two weeks) to get a case started and will be taking it in to a genius bar to have them run a hardware test. I just wanted to do some due diligence and check in this forum to see if others know about this and what it might be. My suspicion is that it's a logic board issue (though I think this may be something I'd read when it first came up and I was checking on it then). The sound is very electronic, not mechanical, and it has two or three parts to the sound (not one pure beep); it is short, but sometimes happens several times over a few minutes' time.

I bought my first Mac, a C2D MBP 13". I really love the machine. But I'm experiencing this particular issue of having high cpu load of up to 80% while on W7 Professional bootcamp even though I'm not running any graphic intensive programs.
Specs: 2.4Ghz MBP 13" (The recently refreshed model)
Windows 7 Professional 32bit (MSDNA Edition)
Upon successful installation of W7, I inserted the OS X disc inside and the bootcamp drivers installed successfully. So I'm quite sure the drivers are okay. Being a DotA lover, I installed WC3 on my bootcamp. However, I realise that whenenver I'm on windows mode, the machine is very laggy. I even have problem opening a browser when I alt tab out from WC3. Is this normal? Even when idle, the cpu load on the processor jumps from 1% to 47% randomly. Just fluctuates randomly. I'm quite sure my Windows Security Essentials is not doing any scan btw.

My MacBook shuts down when the battery drains all the way down. I'm pretty sure back in the days of PPC lappies, they went to sleep before the battery died. Is it supposed to shut down, or is something goofed?

I've got a 17" Macbook Pro from May of 2007 that is serving me well now in my last year of college. The battery health began to deteriorate last year so I replaced it with a new one from Apple (a hefty $120).
Recently, the past two times that I have left for class (with my MBP fully charged) it has drained while shutdown (completely turned off NOT just "asleep"). When I say it drains, I mean it has roughly 2-5% of its battery life left giving me about 20 minutes of power until I get back home for the day.
Here's the kicker: the battery is in good condition with plenty of cycles left (see system profile for power below.)
Any thoughts? Try a new battery? Could it be the charger? What system components, if any, run during a complete shutdown and could these be malfunctioning?

I bought a MacBook Pro September 2007, the last months I have experienced a sudden shutdown of it without any low battery warning. After browsing around the forums I found a app called Coconut Battery which I installed. This is what it showed me: What I can do to get my battery performance better? Do I have to invest in a new battery? And aren't the prices on those extreme?

My 17 inch Mac pro laptop just shut down and I can't get it to turn on again. This has happen multiple times over the last six months. Looked through the forum and tried removing the battery and resetting the SMC control to no avail. I was having issues also with the screen a month ago but that resolved by itself. When I took it into the genius bar for screen problems I was told I'd probably need a new CPU board because the vram may be going bad and they just don't fix that problem. Have held off because of a potential $500 repair and awaiting ivy bridge technology. How I can restart my portable. Right now you turn on the machine and the front light stays on for 2 sec and you hear the machine click off?

I just got a Mac Pro Octo 2.93. It has a 4870 card and 4 1tb drives. I also have a Sonnet E4P e-SATA card installed. Would a 780 Watt 1200 VA surge suppressor be enough?
The other question is about waking the computer up. My old G5 Quad (7800 GT card, E4P card, 2 500gb drives and 8gb RAM) would wake up and while the afore mentioned surge suppressor would beep, the room electrical breaker wouldn't be tripped. Using that same suppressor for the Mac Pro results in the breaker being tripped when the computer wakes up. Would getting a bigger suppressor help with this? In other words, does a unit with a bigger battery capacity allow the battery to take the extra load when the computer wakes up preventing the breaker from tripping?

So I have a late 2008 MBP and the battery is draining way faster than it should. Coconut battery says that my battery capacity is at 93% and it only has 73 cycles but the battery has only been lasting 3 hours at best with a full charge, but most typically, it only lasts 2 hours while using the 9400m GPU and at idle. I have reset the battery per apple's instructions 2 times now and I have reset the SMC multiple times. this is what the system profiler says about my power capacity and consumption:

This all happened out of nowhere one day, I used to get a solid 5 hours on each charge a month ago and now this.

I know I'll never be able to achieve 8-9 hours, but I was hoping for at least 7 or thereabouts. Unfortunately, I only managed a paltry 5 hours on my first two 'complete' discharges. This is with airport and bluetooth on, screen at half brightness and running windows 7 in parallels in addition to the usual browser/office stuff. Is there something I can do to improve battery life? Or is having parallels running all the time draining the battery extra fast? Also, is there some sort of battery monitoring utility that can accurately detect what exactly the battery is doing? I find the default one to be somewhat sparse in terms of details.

Background: Air i7 Mid 2011 4gb RAM, 256 SSD, purchased in Aug 2011. Battery life is normally 5.5hours with wifi on, blue tooth off. I charge the battery until status says charged then I unplug until I get the reserve power message at 9%, most days I charge 2 times, sometimes 3 times. When I plug in an external monitor using my thunderbolt to dvi or thunderbolt to hdmi my battery life drops to 2.5-3.5hours (extra work, less battery, makes sense), back left is hot and fan is running. When I have apache web server, mysql, php, netbeans, firefox with over 30 tabs, safari with over 10 tabs, thunderbird, avast antivirus, adium, skype and other random pgms loaded my battery life stayed over 4.5 hours, activity monitor at about 80% idle. The back left corner of the keyboard stays cool during this time.Â
I have read the CPU power and cores are adjusted automatically based on usage, and this is what I have found to be true with great consistancy. About 1-2 months ago my battery life dropped to about 2.5 hours. I have been trying to figure the cause. At the same time my back left corner of the keyboard is getting hot like I have the external monitor plugged in. The fan is running all the time. I look at the activity monitor and it shows 80%-90% idle. I have been on the phone with support and we tried the SMC reset, but the fan is just doing it's job of cooling the cpu. Apple phone support seemed to feel this was normal, even though I told them the back left of the keyboard was not normally this way. I have narrowed it down to.... the cpu is being told to run harder than before, so where is the mixedup signal? I began this morning reading all the messages here in the disscussions this am (and there are many with the same description), many references to activity monitor.Â
[URL]- the activity monitor in this will show the process that is using the cpu the most. In my case I had installed HP scanner software 2 months ago, which is badly written and very misbehaved, see the following link. This process would go to 100% cpu every few seconds (not all the time, so I could not see it in the summary, ), shown when I sorted by cpu % usage.Â
[URL]I have removed my scanner drivers. My battery life is back to 5.5hr, back left of keyboard is cool to touch, and the fan is off. My findings, when the back left of the keyboard is hot, the CPU is running hard. External monitors heat up the cpu. Activity monitor can tell you what is using the cpu, by sorting by %cpu usage (don't trust the summary, look at the individual processes, as shown in the link TS1473) and watching for 10-30 seconds, a misbehaved app may not be at the top all the time.

Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off.

Just wondering, but how rare is it to have a battery that lasts 3 times longer than the "rated cycle amount"? Apparently this battery should have been dead 600 cycles ago... I am finally now noticing a slight loss in overall battery life.
I have used this MacBook 100% of the time since the day I have gotten it over two years ago. Is this why it has lived so long?

I have searched countless threads about battery health but I feel that each individuals battery health situation is so unique due to the numerous fluctuations.
I have a 2010 13" MBP with battery health of 92%. Load cycle: 13. and Age of 4 months( but i got it 2 months ago)
Should I be concerned with the battery health at this point?

This is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).

I've update my hdd from my macbook pro 13" mid 2010 to an ssd. I've done a fresh install and imported all my apps and settings from my old hdd. Since that time I have 2 problems: when my mbp goes out of battery it shut down instead of hibernating and when I turn it on my finder is indexing my home folder! I have hibernate mode set to 3 as normal.

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?

Does it hurt the computer... If the computer is doing something (watching flash, playing a game) that turns on the fan full speed;Does this hurt the computer? There are a few games I like to play and they turn on the fan at full speed (computer gets hot too, on the bottom.)
