High CPU Usage and Low battery life

Hi to all, I have this problems, my cpu is always over 40% an battery life is short. Before I installed 10.6.2 my battery duration was 4 hours, now is 2 hours. I tryed SMC reset, but the problem is on the CPU usage.

Those permissions messages may be ignored. They are normal.
Because everything is OK in safe mode you need to track down what isn't active in safe mode that may be causing the problem you are having. Of importance are:
1. Incompatible third-party extensions (drivers) such as may be used for third-party peripherals.
2. Incompatible items located in the /Library/StartupItems/ folder or /Home/Library/LaunchAgents/ folder.
3. Bad fonts located in the /Home/Library/Fonts/ or /Library/Fonts/ folders.
4. Incompatible item in your Accounts' Login Items section.
5. Corrupted caches located in the /Library/Caches/ and /Home/Library/Caches/ folders.
To test the corrupted cache possibility simply remove the above mentioned cache folders to the Trash (but do not delete) then restart the computer normally. If the problem is resolved then you can empty the Trash.

IcedTea High CPU usage and multiple jobs created

High CPU usage and multiple jobs created while streaming data via a java applet from a secure/certified website. CPU usage is normal for a few minutes then suddenly jobs multiply and CPU usage climbs on one of the jobs.
Jobs with the following command begin to multiply in my job queue with one job showing CPU usage at 368% and staying resident in memory (yeah, a long one):
/usr/lib/jvm/java-7-openjdk/jre/bin/java -Xbootclasspath/a:/usr/share/icedtea-web/netx.jar:/usr/share/icedtea-web/plugin.jar:/usr/share/java/js.jar: -classpath /usr/lib/jvm/java-7-openjdk/jre/lib/rt.jar sun.applet.PluginMain /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-plugin-to-appletviewer /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-appletviewer-to-plugin /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-plugin-debug-to-appletviewer

I also get the following message in my system log when starting to stream:

Anybody having this issue or clue on what to do? I am wondering if recent changes to openssl (heartbleed) might have java change ramifications? Should I submit bug to Icedtea?
FYI - My system:

...further research and learning.
Here is a good tutorial on Java. Evidently, what I called "jobs" is referred to as processes and threads in this tutorial. The tutorial states that multithreaded execution is an essential feature of the Java platform which explains the avalanche of threads I observe. However, I am still stumped at what causes the avalanche of threads and excessive CPU consumption for such a mediocre task. Also the system log says that IcedTea has an error stating "Application title was not found in manifest. Check with application vendor". I interpret this to mean that IcedTea does not recognized some application. What application? .....the applet?

Microsoft Office 2004 -- extremely high cpu usage and virtual ram

hi,
when i use office it causes a very high cpu usage even when its in idle mode.
i am unable to work with it, because its extremely slow.
does anyone have same experiences?
thanks for your help!
mbp 2.0 1,5gb ram 80gb hdd Mac OS X (10.4.7)

I am able to work OK with office, I'm using the 'old version' Microsoft Office v.X, not much details in the About Box, just listed as MSoft Word/Excel/etc for Mac service release 1.
I get the occasional crash, and I have seen Word in particular use 90% of a single core and amazingly large virtual memory usage, gigabytes sometimes, but eventually the document gets printed.
It shows how useful the dual core (or quad) cpu approach is!
One cpu for Word to print, and one cpu to run the rest of my applications/life!
I still use this old office rather than re-booting into Window§ for whatever is the latest version of office.
Doing some playing with a similar one page document in Office v.X and Pages 2.01, I get Word using about 25% of a core , Pages using 5%, - whilst editing; Intel native Pages has 20% of a core and 80MB ram 480 virtual whilst printing, Word has about 100% of a core and 65MB ram 650 virtual whilst printing, but it is a powerPC code so Rosetta is in there somewhere.
check Activity Monitor or other apps/widgets for some parasitic processes? have fun!

High CPU Usage and Temperature

I've recently purchased a MacBook with the latest updates, including the firmware for the random shutdowns but lately when I boot the MacBook up, the fans kick on and it reads 83 degrees Celsius with about 65% CPU Usage and I don't have anything running except what came on the MacBook in itself, any suggestions?? Apple told me to take it in to have it looked at but I was wondering if there is anything I can fix perhaps?? Thank you

Sometimes when I connect an external drive which I have made drastic file changes to, there are two process that eat up a lot of cpu power and get the macbook really hot for awhile, those two processed are related to the way spotlight tries to re-index the external drive or the internal hd itself if I had made drastic changes to it too.
Could it be that?
You can see them show up in Activity Monitor, they are mdimport and another one starting with md(something) too.
Hope that helps (if that's the issue)
Best,

Portege Z930 - "System" process: high CPU usage when on battery

I've got a Portg Z930.
A process called "System" appears on the task manager when I unplug the PC from the AC.
I'd like to know why is it using high CPU (from 9% to 18%) and keeping my temps above 70C.
It's very annoying, not only because of the temperature that hits the PC itself, but also because of the battery life, that can't go above 1 hour and 30 min because of this process.
It's not a virus, already CHECKED, don't ask.
Also, I don't know when it started or why, so please don't ask.
Thanks in advance,
Nicols.

> I'd like to know why is it using high CPU (from 9% to 18%) and keeping my temps above 70C.
I dont know exactly what this system process does but usually the Windows system uses different power plans / modes while the notebook is connected to AC adaptor and while running on battery power.
So possibly the power plant for battery mode is configured differently.
I would recommend checking the power plant which is used while the AC adaptor is connected and compare the settings with the power plant used in battery mode.

Powertop reporting 100% PCI device usage, and poor battery life

I have Arch running on an HP Pavillion g4-1200tx laptop with these specs:
2.2 GHz Intel Core i3-2330M 3 MB L3 cache
4 GB 1333 MHz DDR3 Memory
AMD Radeon HD 6470M (1 GB DDR3 dedicated)
A vanilla install of Arch eats up the battery at around 28 watts.
After doing some power tweaks, mainly
Installing and configuring tlp
Activating the i915_enable_rc6
Disabling the discrete GPU with vgaswitheroo
and with the wifi/bluetooth radios off and cpu scaled to powersave, it consumes 20 watts and is uncomfortably hot.
Powertop reports stats as follows:
I think this is because the PCI devices are at 100% use. But PCI runtime power mgmt. is active through tlp. I've tried laptop mode tools but tlp comparitively gives better results.
Here is the tlp stat output.
What should I do to improve the battery life and make it run cooler?
Last edited by vn14 (2013-05-01 12:52:30)

Oh! I thought it was so because PCI was at 100%.
The GPU is disabled.
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:DIS: :Off:0000:01:00.0
1:IGD:+:Pwr:0000:00:02.0
Also, it's not a desktop environment's fault (I'm running KDE); Same amount of power is consumed even when X is not running.
Is there a way to find out why the power consumption is so high?
How much power does Arch consume normally?

Noisy fan, very hot case and low battery life

Hi
Got a new Aluminium Powerbook 1.67 in Feb of this year, plus 2 spare
batteries.
Initially I was very happy at how quiet it was and how cool it was running..... however....
The fan has become really noisy and the case gets very hot ( near the power in )
The batteries will only ever give me exactly 1.5 hours of use even after firmware upgrades and restting the PMU, PRAM etc. ( this is with light use )
Looks like it'll have to go back to Apple for the fan, I just wondered if anyone else had similar problems and whether they got resolved to their satisfaction?
Regards
Graham

Graham,
Excess heat will certainly reduce battery life, so you should get your pB looked at ASAP and have the fans taken care of.
Definitely think about getting AppleCare.
Did you ever properly calibrate your batteries?
Simply run them past the low-battery warning until the pB goes to sleep. Then plug in the Adapter until fully charged. May have to repeat this a couple of times.

High cpu usage and game lag problem

i have a hp 15 d103 tx
windows 8.1 64 bit

im experiencing huge amount lag in games and software (autocad)
whenever i run a game (for eg batman origins) it run smooth till 2 or 3 minutes after it lag horrribly
for sake first im getting 45 frames per second then suddenly frame drop to 13 or even to 10
i have to press alt + tab to check task manger it show cpu usage 30%
after that when again i press alt tab to back to game it runs fine for 20 seconds and again lag
i dont what the problem high cpu uasge
system idle process sometime shows around 82%
with 8gb of ram still expericing lag
this problem is with all game that i have played and software like photoshop and auto cad
my cousin own hp 15 r007tx and having same gpu nvidia 820m game runs for on his laptop without a lag
is it window 8 problem or something else??

wow finally got the solution by updating bios
just updated the bios from 2.7 to 2.8
no lag now
i guess different cpu load gpu switching on off was problem
but now everything is running good

IPhone 4 hot and low battery life?

Why does my I phone 4 have such a small battery life? And it is running hot

Hello Bmay121,
Thank you for providing the details about the issue you are experiencing with your iPhone. I found a couple of resources that may help address this issue.
First, I recommend following these steps if your iPhone has a short battery life:
Battery life seems short
Click ( www.apple.com/batteries/iphone.html) for tips on how to prolong iPhone's battery life.
Try turning iPhone off and then on again.
Connect iPhone to iTunes and restore iPhone.
If the screen shows a low-battery image, the battery is low on power and needs to charge for up to ten minutes before you can use it.
When charging iPhone, make sure to leave it charging until it is fully charged. You'll know the battery is fully charged when the battery icon in the upper-right corner of the screen looks like this .
Note: When charging using a computer, don't connect iPhone to a keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPhone is connected to a computer that's not turned on or is in sleep or standby mode, the iPhone battery may drain.
You can find the full article here:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
You can also find useful information about the iPhone's operating temperatures in this article:When troubleshooting temperature, please refer to the following article:
iPhone, iPad, and iPod touch (4th generation): Keeping device within acceptable operating temperatures
http://support.apple.com/kb/HT2101
When using the device or charging the battery, it is normal for it to get warm. The exterior of the device functions as a cooling surface that transfers heat from inside the device to the cooler air outside. If the interior temperature of the device exceeds the normal operating range, the device will protect its internal components by attempting to regulate its temperature. If this occurs, you may notice the following:
The device stops charging.
The display dims or goes black.
If the temperature continues to be a concern, you can isolate the issue by restoring your iPhone as new:

High CPU usage and program slowing down

Hi. I have helped write a program in AS3 that uses classes. We have 2 frames in our movieclip that consists of an ant moving. We have a class of ants and can create 15 instances of them and the program runs fine with the ants walking around looking for food and going back to a corner that is their nest and going back out again. The ants also respond to mouse movement if the mouse pointer is near an ant.
If we create more than 15 ants, then the program starts to slow down. If we have 30 ants on the screen, then there is noticable stuttering of the ant movement. The CPU usage on a P4 2.5Ghz Pentium is around 50%.
Is this normal? or is something wrong?
I would have thought we would be able to scale up the number of ants easily.
Thanks
Trev.

Hi kglad.
Thanks for the reply.
I assume enabling cacheAsBitmap is set in the ant class Constructor, as we have tried that and it has helped, see below. We can now create 30 ants with very slight stuttering.
We have an ant class as below.
public class TAnt extends MovieClip { // lots of code here }
ant Constructor as below.
public function TAnt(newX: Number, newY: Number, sW: Number, sH: Number, rCyc: Number) {
            this.cacheAsBitmap = true;
           // more code here }
// We have implemented a Finite State Machine for the ant behaviour.
regarding the ants using a loop and using a controller class, I am not sure what you mean.
We are creating instances of the ants in the Ants.fla file which is in the Action file and add each new ant to an array. See below.
for (var a = 0; a < nAnts; a++) {
    var newAntX = Math.random() * screenWidth;        // randomly generate ant location
    var newAntY = Math.random() * screenHeight;
    var rCyc = Math.random() * 800;
    var ant = new TAnt(newAntX, newAntY, screenWidth, screenHeight, rCyc);            // create ant
    addChild(ant);                                                   // add ant so visible on screen
    ants.push(ant);                                                 // add ant to array
So we use an array for looping through the ants in the Ants.fla Action file.
Is this the way you mean?
Thanks
Trev.

Wireless driver triggers warm/hot macbook and low battery life after OS 10.8 mountain lion upgrade

Hello frustrated Macbook users.
I have tried to get help on other Apple discussions but no one seems to want to help, they aren't actually reading my posts, or they hate me for some reason.
No matter.
If you have a warm Macbook that has 2.5 hours of battery life where you used to have 4 or more, please do this simple procedure and write the result below.
Turn OFF Airport wireless networking
Perform an SMC reset (Power Manager)
Connect an ethernet cable and use your Macbook normally. (but do NOT turn on wireless networking again)
How is your battery life after doing this?
I have a user over here who reclaimed decent battery performance if he doesn't use his Airport wireless.
I need confirmation.
If so, I may get a USB wireless adapter and see if the battery life stays good.
Bonus points: If you have a Mac compatible USB wireless adapter and got good results by turning off the built-in adapter, want to test it for me and report the results?
Thanks and good luck!

UPDATE:
Problem persists when using Recovery Partition.
Chance sthat it is third party softwae or updates is more or less eliminated.
Update 10.8.3 beta fixed the problem for one lucky early adopter.
Hypothesis: New battery charging algorithms programmed into Mountain Lion OS10.8 triggered problems from design flaws that were NOT an issue for OS 10.7 and before.
Battery replacements were successful where the replacement battery was built within tolerances that did not fail under 10.8's new charging algorithms. Other bateries did not meet those tolerances so you would get spotty results from battery replacements. It worked sometimes, but not always.
OS 10.8.3 may have adjusted these algorithms to be less demanding on the features of the battery that were failing.
Official word from Apple is 'mum'.

Persistent Active Requests causing high CPU usage and load average

Hi, we've deployed a JSP application on standalone OC4J talking to Oracle DB. The whole thing runs on Sun Solaris. On some occasions (still investigating what causes this), the number of active requests rises (as seen from EM console) and never drops down. The weird thing is, the load average numbers are proportional to the number of persistent active request. If there are 3 active requests, load avg will be [3.x 3.x 3.x], and whenever persistent active request exist, CPU usage will shoot up to over 90% (usually between 95% - 100%). When the system is running normally, CPU usage is usually less than 20%. Is it possible to track down this problem and how? Many thanks.

Welcome to Apple Discussions!!
The icons on the right of the menu bar … show a beachball when I put the cursor over themWell, if this was your only problem I would put it down to a corrupt preference or cache file. Nevertheless, it is worth seeing how much this helps.
The file you need to trash is 'systemuiserver.plist'. But there are potentially two of them, plus it is best to delete your caches as well, so ...
In "/Users/<yourname>/Library/Caches", delete everything
In "/Users/<yourname>/Library/Preferences", delete com.apple.systemuiserver.plist
In "/Users/<yourname>/Library/Preferences/ByHost", delete com.apple.systemuiserver.xxx.plist where 'xxx' is a 12 digit (hexadecimal) numeric string.
See if this improves the situation, and post back with any remaining oddities.

Rim.desktop.exe high cpu usage and internet activity

What the heck is going on with desktop 6 software? Rim.Desktop.exe is running 10-20% cpu utilization and my router lights are blinking like crazy. It won't shut down right away while this is going on either. I have to force the shutdown to close the app and stop the internet activity. This goes on when my phone is connected or not. Storm 9530.
Dean

Thanks for the quick reply.
If you do not have that 3rd party add-on running, do you notice a difference in the cpu usage? or network connectivity?
Also did you experience any of these problems with running with DTM 5.0.1
The only network connection that Desktop Manager uses is to register the PIN number and to check for updates and down the new updates. But it does not continue constantly.
I would see if you can use BlackBerry Desktop Software without the 3rd party add-on unless you tried before, to see if it's a third party add-on causing the issue or Desktop Manager.
I look forward to your results.

Flash causing abnormally high CPU usage and overheating when browsing internet

Hello,
Flash Player (Safari Internet plug-in) spikes to 110-120% of my CPU usage while browsing the internet. This also causes my computer to overheat. (This also occurs when using Firefox)
I am running OSX 10.8.4 and I am using Adobe Flash Player 11.8.800.94
I have tried uninstalling through the Adobe uninstaller and resetting Safari and my computer.
I contacted apple care and they said it was a problem with Adobe and I needed to contact you guys.
Thank you for your help.

The link you posted is fine. its only around 9%

High CPU usage and continuously running fan

I recently sent off a logicboard to be repaired for a non-charging issue. Everything worked fine with the exception of the battery would not charge. I received the board back today and noticed immediately that the fan starts running at high speed within 10 seconds of pushing the power button. It also boots extremely slow and when it does finally, eveything takes forever to open. It seems to operate better in safe mode but the fan is still running at about 6200 rpm. Using iStat, I noticed that the temperature itself is not that bad. The CPU is running at about 32 C. And it doesn't feel hot to the touch at all. But the fan never shuts off. I have tried an SMC reset and PRAM reset, no joy. I tried a new hard drive, still no joy. When I can finally get into Activity Monitor, it says that Kernel_task is using upwards of 200% of the CPU. Any suggestions on what I can try to get this kernel_task issue corrected and get the fan to slow back down? Thanks in advance for any light anyone can shed on this.

I was able to run the Apple Hardware Test and the error is:
4SNS/1/C0000008: TsOP- - 124
Apparently that has something to do with a temperature sensor. Of course, I can't find any information on how to replace it or even where it might be located. Don't even know if it's replaceable. Can't believe I just got this logic board back from being "fixed" and it's not "fixed!
