Powerbook G4 runs hot after OS X upgrade

I have a powerbookG4 that had 10.3.7. I upgraded today to 10.3.9 and upgraded iTunes from 4 to 6. (looking at the iPod video requirements) Now I'm noticing that it seems to run much hotter. I was on the internet, using AirPort (as usual) but the fan seemed to be running much faster and the bottom of the computer was almost too hot to touch. Plus, I also noticed in this form, that the computer automatically filled in the OS X form with 10.3.7, tho' I have verified in the 'about this apple' page that it now has 10.3.9.
Any suggetions? I wouldn't think running hot would be good for it, and if I want to use it on battery power, would use more power for the higher speed fan. (I did notice tho' that when I turned off AirPort for a few minutes and turned it back on that it's slowed the fan down some, and seems to be cooler, even after turning AirPort back on. Interesting.)

Welcome to Apple Discussions!
It sounds like you do may not be using the right discs. If you want to install Leopard, you will need the retail DVD--black with the purple aurora. If you want to install the original OS (Panther?), you need the exact install discs for the PowerBook. If you don't have these, you can call Apple with the serial number and get a replacement set for a fee.
Any other gray machine specific discs will simply not work. These are optimized for the computer they were shipped with.
The ?/Mac face just reflects the fact that the drive you erased is empty and there is no OS on it.
The idea of erasing and reinstalling the system software is basically a good idea. It just sounds like you are trying to use the wrong discs and will need to try to acquire the right ones.
Good luck!

  • My PowerBook G4 runs hot after installing iTunes 7.1

    Only Safari and iTunes open. The iStat Pro shows the CPU bottom and top around 55 degree Celcius (but the temp haven't changed since then...crash between 7.1 and iStat? but I can feel my PB runs hot)
    Anybody got the same problem?

    Ditto here.
    Mac OS 10.4.9. iTunes 7.1.1 (5)
    Airport Extreme Base Station "chained" to 2 Aiport Express Remotes. All connections are fine. Have internet on remote Macs. Airport Admin utility displays all three airport units, but I'm now unable to broadcast to the remote Express hooked up to my stereo in adjacent room. Have done this many times in the past without problem, but not in past couple months, so can't say if it broke with 7.1 or 7.1.1, but I get this message from iTunes:
    The remote speaker "Living Room Speakers" is not compatible with this version of iTunes.
    Prior to restarting iTunes (and being sure all Aiport station firmware was up-to-date, I was getting the message that no speakers were connected (double-checked all speaker and stereo connections), but now just the "not compatible" message.

  • MacBook Pro running hot after Mt. Lion upgrade

    MacBook Pro mid-2009 2.53 with 8GB RAM and 750GB 7200 rpm harddrive: CPU seems to be running much hotter (>70 degrees C) and fan is the normal 2000 rpm per iStat after upgrading to Mt. Lion 10.8.1 and 10.8.2.  Bottom of laptop near center screen side is the hottest area.  Any ideas why?  Or how to cool it off again to the way it was before the upgrade from Lion?
    Thanks.

    Thanks for your links.  My MacBook fan was running constantly from switch on and the underside was getting very hot.  Using your first link, I followed the Activity Monitor instructions and found that Dashboard was using '117%'.  As soon as I closed it down the fan instantly slowed and after only a few seconds switched off..
    Thanks again..

  • CPU runs hot after Snow Leopard upgrade

    I upgraded to SL last weekend and noticed the next day that the fans were constantly running really loud. After extensive research (there are some other threads about this, but no solutions) and troublshooting, here's what I've learned:
    - It's not related to Spotlight indexing, as the problem continues after indexing is complete
    - PMC and PRAM resets don't fix the problem
    - Activity Monitor shows a process in the root called "ptmd" (platform thermal monitor daemon) consuming over half of my CPU. Killing the process resolves the issue, and the system still seems stable, but I don't know what it is, why it's running, and if it's really ok to kill it. I've read that some computers run it at startup and then automatically kill it, and others constantly run it. But I don't know which category my computer falls under. Either way, I've never had to kill it before upgrading to 10.6 and shouldn't have to kill it after every restart now.
    - iStat shows my CPU getting to around 80°C+, and my fan running at 6000rpm+. Once I kill ptmd, the CPU temp will gradually drop below 50°C and the fan drops to under 2K rpm.
    I don't remember if the problem started right after the upgrade or only after running software updates in Snow Leopard... But I started fresh -- I erased my HD and installed SL fresh. No problem until I ran the 10.6.3 combo software update, then the ptmd problem came back. I've since done another fresh install and am doing a step-by-step software update. I have 10.6.1 installed with no trouble, even after a restart. I'm currently downloading 10.6.2, which I expect will introduce the issue again, based on the fact that that's where people started having problems in the forums that I've read. I suppose I could just find the most recent "safe" version (probably 10.6.1) and stick with that one, but I would like to make sure that the other important updates are installed. Has anyone else heard of this? Is there anything else I can try?
    A secondary concern is that I only ran a Time Machine backup after installing 10.6.3 (I know, stupid to not backup before the upgrade). If I restore my backup with Migration Assistant, am I going to just re-introduce the problem on my computer?

    According to the man page for ptmd, the ptmd daemon "relays to hardware any OS notifications effecting thermal conditions." IOW, it is just the messenger sending messages from the OS to the hardware. If it is using a lot of CPU time, the OS apparently very frequently thinks thermal conditions are changing & that the hardware should know about it. Thus, high ptmd activity would seem more a symptom than a cause.
    Also, while my MacBook is a 4,1 model & not a 2,1 one like yours, the ptmd process terminates after startup, so assuming they are sufficiently similar in terms of thermal management it may be that whatever is failing to tell the process on your MB to terminate after startup is part of the culprit.
    This is unlikely anything in 10.6.3 -- on all my Macs, the modification date of the /usr/libexec/ptmd file suggests that it has not been changed since 10.6.2. In fact, it is unlikely anything in any Snow Leopard update, since most users do not have this problem, regardless of model or 10.6 version.
    I realize you said you did a fresh install & the problem disappeared, but for this kind of test to be definitive, you cannot allow any preexisting file that might have an adverse effect on system operation to remain active. Unfortunately, there are many types of files that can do this. Sometimes these files affect nothing besides the update process itself, making it seem as if the update is the cause when it actually is an effect.
    Since there are so many kinds of files that can have adverse effects, it can be difficult to identify the offending one without first doing some diagnostic detective work to determine where it might be lurking in your Mac. A good way to start is to start up in Safe Mode, which loads only essential system components (see Mac OS X: What is Safe Boot, Safe Mode? for more about this). If the Mac doesn't heat up in Safe Mode, then you know one of the non-essential items is the cause.
    You can determine if the problem file is in the user or system domain by creating a new, temporary user account. If automatic login is enabled, temporarily disable it -- it is important for this test that you log into this account for the first time immediately after restarting the Mac, before logging into any other account. If the Mac doesn't overheat now, then you know the problem is somewhere in the normal user account's home folder.
    If you are willing, try these tests & let us know your results. That will make it much easier to suggest where the offending file might be & what to do about it.

  • Why is my MacBook Pro running hot after mountain lion upgrade?

    The fan is on high all the time and the system is running very hot. It also consumes the battery way faster than it used to.

    Thanks for your links.  My MacBook fan was running constantly from switch on and the underside was getting very hot.  Using your first link, I followed the Activity Monitor instructions and found that Dashboard was using '117%'.  As soon as I closed it down the fan instantly slowed and after only a few seconds switched off..

  • Ipad running hot after 8.3 upgrade

    I just upgraded my iPad to 8.3.  In the couple of hours since, it is uncomfortably warm to the touch. I've stopped all running apps and forced a shut down while I let it cool off. Is this a known issue with this upgrade?

    What you need to do is what many others have done, and that is to reset your iPad to factory default condition by using your iTunes program. And ... don't forget your backups.

  • Running hot after mountain lion install

    Hello,
      I just installed Mountain Lion last night. I had no issues at all. Checked out some of the different new features and all seemed to work fine.
    But this morning after I turned my MacBook Pro back on is where I noticed something odd. I was using messages and also Safari. It was working great. My baterry was at 99% when I first turned it on. After about an hour of use I noticed the battery down to 67% and that Safari was not running as quick. It's not that it was not responding just running slow. Real slow. So I turned it back off and let it sit for a half hour and started it back up. Seems to running ok now. I even have a few programs open as well as the last time.
    I just wanted to post here to see if anyone else had this issue. I think it's isolated and maybe some things didn't boot enough after install. Thoughts on this from anyone is greatly appreciated. Again it is runing fine and the slowing issue does not seem to be there now.
    Thank You

    Yes, me too. My Activity Monitor shows Safari Web Content absolutely destroying the CPU, exceeding 100%. Slows the whole system up just browsing.
    Just compared browsing a facebook album in Chrome and Safari 6. Safari crawls through it with the CPU jumping immediately to over 90% while Chrome's processes barely ever reach 20%.
    Also read this which suggests Spotlight's indexing is a potential cause but on my MBP (late 2011) Spotlight isn't shown as active:
    http://gigaom.com/apple/is-mountain-lion-too-hot-for-your-mac-to-handle/
    and also the CPU only runs hot while on Safari. Processor-heavy XCode consistently runs fine.
    Assume a Safari bug. Anyone else experiencing this?
    UPDATE: Restarting Safari makes a massive difference both to the real memory and the %CPU figures.

  • My iPhone 4s seems to be running slower after the os6 upgrade. Anybody else having this problem?

    My iPhone 4s seems to be running slower and crashes after the ios6 upgrade.  The power off button does not appear when I try to power it off, the screen just goes blank.

    Mine seems to be running faster after the upgarde although i am facing battery drainage. Best you do a hard reset to the phone and this should solve the issue. Apparently if you upgrades via OTA, there were some issues. hope this helps

  • MacbookPro 17" runs hot after 10.10.3

    This laptop now runs hot and makes fan noise since upgrading to 10.10.3.  This only happens when I have an Apple Cinema Display connected and the laptop is closed.  When the monitor is connected and the laptop is open - everything is normal.  This only started when I went to 10.10.3
    Thanks

    How hot is hot.  Actual numbers help.
    Open Activity Monitor to ALL PROCESSES and see what applications are taking a lot of the CPU/GPU resources.
    Since you have installed a new OSX, Spotlight may be reindexing the HDD.  When that finishes, the problem may go away.
    Ciao.

  • Satellite A110 (PSAB0) running hot after BIOS update

    I updated the BIOS on my Satellite A110 (PSAB0) to the latest version and now the laptop runs hot - the fan runs constantly and the battery drains from full to empty in minutes.
    Is there a setting or another update to cure this problem or how can I restore the old BIOS?
    I am sure I opted to save the old version during the update but I can't find it on my laptop.
    Thanks for any help

    Have you tried resetting the BIOS to its default settings?
    Also try updating the Toshiba Power Saver and Common Modules, and check that the power options are set to dynamic CPU speed to avoid the CPU from running full speed all the time.

  • MacBook Pro running hot after upgrade

    Hey everyone,
    First off: Upgraded to Mountain Lion and I absolutely love it. I'm running on a December 2011 MacBook Pro Unibody 15", 8 Gigs ram, i7, SSD 256 drive (Apple). It had Lion installed when it came, obviously.
    Now that I upgraded to Mountain Lion, it's running several degrees celcius hotter than before, after a couple of hours of using it. I figured I'd give it a few hours to do its search database thing etc...you know, let the system stuff in the background settle down, but it's still running very hot.
    Is this something which eveyrone else has been experiencing? I've got two methods of checking the tempurature: iStat Nano on the Dashboard (which I don't use for anything else...) and smcFanControl which sits in my menu bar. Both give me the same tempurature and it's running literally about 5 to 7 degrees more (or sometimes even spiking at 15 degrees more for a few seconds) than before.
    Just wondering if I'm the only one? Should I be patient and give it a day or so? Any tips?
    Thanks,
    Nat.

    You're right that in the first few hours ML will be busy in the background running certain processes like indexing Spotlight and Time Machine.
    You can see if these are still indexing by looking at the menu bar. Click on Spotlight - if you get a progress bar saying its indexing, just leave everthing alone till its finished. If you look at the TM icon, it should be slowly circling if TM is still indexing. Again, click on the icon and see what it says.
    If these seem to have completed, check in Activity Monitor.app (Applications/Utilities/Activity Monitor.app) as to what is using up %CPU time. If you see kernel_task is running wild (+80%) , try a PRAM reset. To do so, folllow this procedure:
    1. Power down the machine.
    2. Locate the following keys on your keyboard in preparation for Step 4:
    ‘command’ – ‘option’ – ‘P’ – ‘R’
    3. Press the ‘power on’ button.
    4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
    5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should and with the kernel_task process back to normal.

  • IMac runs hot after Mavericks upgrade

    after upgrading from Mountain Lion to Mavericks the machine (mid 2010 IMac 27 inch) runs much hotter than before. I was hoping the power management would rather be better than worse. The upper part of the enclosure get too hot to touch comfortably without excessive load e.g. just some office programs and safari running. This even now in winter time when room temps are only about 20 deg C = 70 deg F.  The fans are running higher than before.
    As no topics like this are found, a general compatibility issue could most likely be excluded.
    What should be checked?

    Do 2-3 SMC Resets, or it also may simply be re-indexing Spotlight. Check Spotlight to determine if that is the issue by hitting Command + Spacebar and see if it's reindexing.

  • MB running hot after upgrade to mountain Lion

    After upgrading from snow leopard to mountain lion my MB2010 is running very hot. It's been almost a month since the upgrade so I refuse to believe re-indexing files can be the reason. I see others with MBP/iMac having the same issue, I suspect this is a bug. It keeps the fan going and CPU temp reaches 95degC on a regular basis. It's killing the MB battery and I fear for my fertility....
    Is Apple going to solve this issue?

    Hi Dave,
    Thanks for your feedback,
    I did look at what applicatione were running and checked the memory usage when forcing termination of the individual apps in a sequence, but I noticed no major difference yet... I did not check the CPU load specifically, I used the system monitoring widget for this. I have just checked temps in AM that is indeed useful... but i find no clues there either. What in the Activity Monitor do you recommend monitoring? I just checked and the total CPU load is around 15% and all apps indvidually below 5% (I'm not running CAD programs or other CPU heavy programs typically...).
    Still the CPU gets hot. When I don't use it I now put it on the floor (nice cool tiles) so the heat can dissipate.

  • Powerbook G4 Running SLOW after 10.4.4 upgrade

    I am new to Mac and just set up a new PBG4. I installed all of the updates as soon as I set-up OSX for the first time. Now, everything runs slow, especially Safari. Anyone else experiencing this? Any suggestions?

    How did you upgrade to 10.4.4? Did you use the Combo Updater or the one provided via Software Update? If the latter, I suggest you download the Combo Updater and reinstall the update. Before doing so, however, do the following:
    Boot from your OS X Installer. Be sure to use the installer for the version of OS X you have installed. After the installer loads select Disk Utility from the Installer menu (or Utilities menu if using Tiger.) After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.1.1 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    If the computer continues to run slow then I suggest downloading one of the several cache cleaning and maintenance utilities and clean out all your caches, run the maintenance scripts, and check for bad fonts. Read the FAQs on optimization and maintenance at The XLab FAQs. Contrary to other advice repairing permissions will not make OS X run faster.

  • PowerBook Running HOT After Leopard Install

    Ever since I installed Leopard, my powerbook runs so hot that swear it's going to melt! Even with just one program open for a short time (like Apple Mail) the fan will be running and the unit seems like it is being overworked or something. Is anyone else experiencing this? Is Leopard so advanced that a powerbook just a few years old has a hard time running it? Any suggestions?

    Thanks for your willingness to help me out.
    I think the layout of Activity Monitor may be a little different in Leopard...what I am looking at under the CPU button says that the user has 100% usage on the CPU and the bar chart is totally filled in green. What the CPU column says under "all processes" is that some program called lexmarkcupsdrive (I have no idea what it is) is hogging most of my juice–if the 93.1 is the % usage. I pasted all the info on that below:
    "85 LexmarkCUPSDrive _lp 93.1 3 4.05 MB 736.61 MB PowerPC"
    This is seems weird because the user is"_lp". I have no idea what that is either. For the most part, all the other process users look legit like "root" and the name of my home folder .
    Do you make anything of this?
    My powerbook never used to heat up or even seem like it was working unless I was watching a dvd or using iTunes with tons of other programs open–the issue really irritates me.
    If I see processes in my activity monitor that I don't recognize, or that look suspicious should I take action?
    Thanks for your help Bob,
    MacUte
