Random Shutdown While Running On Battery

I've been experiencing random shutdowns when running on the battery of my iBook G4 12" (2004). The iBook has been working fine when the power adapter plugged in and I don't know the route of the problem! If anyone could enlighten me it would be much apppreciated! I have run the Hardware Test and everything has come back thumbs up. I'm thinking this maybe a Logic Board problem, im hoping that it isn't because that is costly!
Any help is greatly appreciated, Cheers.

Hi,
Welcome to the Discussions.
I would suspect a bad battery. It's ~2 years old (the average life of a lithium ion battery) and it doesn't happen when plugged into the mains. Older batteries often report false information about the percent of charge in them. It can read 60% when in fact it's 1%.
Go to Apple Menu>About this Mac>More Info and see what the capacity of the battery is and the number of charge cycles.

W510 checkered pixel patterns while running on battery [workaround]

Hey all, got my W510 in the mail yesterday and am quite pleased with it so far, but I have one issue that I've determined to be related to the power profiles. When using any energy-saving power profile while running off battery power, when I have a flash website (e.g. Nvidia's homepage) open in IE or Chrome or if I move any window around the screen enough, some kind of strange pixel checkering occurs constantly when the screen has too much activity. It's as if every other pixel gets shifted over by one making what looks like a checkerboard out of all the pixels on the screen. I can still read the screen, but it makes my head spin.
If I choose the standard 'Max Performance' power profile, the issue doesn't manifest when running on the battery. If I choose any of the others or create my own profile to mimic the Max Performance profile, I still get the checkers. It still manifests if I go through and turn off all power-saving options or increase the brightness of the backlight. If I start with the Max Performance profile and adjust it to my needs, the problem doesn't occur. Something tells me that the performance profile has something subtly different than all the others and it's not a configurable setting.
Has anyone else experienced this problem? Should I upgrade my Nvidia drivers from version 188.25, which came with the machine? I've read that other people have had issues upgrading their Nvidia driver. The way the system behaves, this seems like a power management issues more than an Nvidia driver issue.
Edit: I should also add that I don't have the issue while running on the AC adapter. Also if I take a screenshot while the pixel shifting occurs, the screenshot is crisp and clear with no signs of the pixel problem. This seems purely hardware/power management related.
Edit: see my later post on adjusting the power settings to work around this issue.
Solved!

It's reasonably likely that whatever issue you're seeing is linked to a setting in the NVIDIA Control Panel. So the best diagnostic you can do is, in high-performance mode (where the problem DOESN'T occur), write down the value of EVERY single setting that's available in that control panel.
Then, put the machine in a power mode in which the problem DOES occur. Then again go into the NVIDIA Control Panel and check every single available setting to see if anything has changed. There's a reasonable chance that you'll then find out what setting is causing the problem.
A picture is worth a thousand words, and a video probably ten times that. Taking a close-up shot of the screen while the problem is occuring, with either a still camera or preferably a video camera (or both), may help siginifcantly in diagnosing the problem. A simulated picture may differ in some subtle way from what's really happening, and those subtleties may be important. For instance, does the effect only break up vertical lines, and not horizontal lines? And does it only happen to content that is moving on the screen? And you're running your display at its native resolution, and not some larger or smaller resolution, right? Is the horizontal offset in the effect always just one pixel-width, or is it more than one pixel-width if you move things fast enough?
The simulated picture that you provide looks like it suffers from an artifact that appears WITHIN moving items that are displayed on an interlaced-scan display. The artifact goes away when the item ceases to move. But these aren't supposed to be interlaced displays. And I assume that you're talking about the built-in LCD in the W510, and not some external display, right? If somehow your display card is in interlaced display mode, then the problem probably won't appear in any screenshot the W510 takes of its own display. So at least that part of such a problem would agree with what you're describing.
So maybe the card is in an interlaced display mode when it's not supposed to be. Such a setting would normally be contained under some sort of "Video" menu in the NVIDIA Control Panel.
And from nVIDIA's website:
http://nvidia.custhelp.com/cgi-bin/nvidia.cfg/php/enduser/std_adp.php?p_faqid=2343&p_created=1231528...!!&p_li=&p_topview=1
"Graphics card temperatures typically range from 40°C to 90°C."
The only mention of interlacing that I see on their site for that graphics card is in the "Features" section of:
http://www.nvidia.com/object/product_quadro_fx_880_m_us.html
"PureVideo HD Technology
NVIDIA® PureVideo® technology is the combination of high-definition video processors and software that delivers unprecedented picture clarity, smooth video, accurate color, and precise image scaling for SD and HD video content. Features include, high-quality scaling, spatial temporal de-interlacing, inverse telecine, and high quality HD video playback from DVD."
Plus there are many references to interlace features in the "NVIDIA Accelerated Linux Graphics Driver README and Installation Guide" which covers your video card. And those features are also presumably present in the Windows driver as well:
http://us.download.nvidia.com/XFree86/Linux-x86_64/195.36.08/README/README.txt
One such reference is:
"While [it] is possible to apply de-interlacing algorithms to progressive streams using the techniques outlined in the VDPAU documentation, NVIDIA does not recommend doing so. One is likely to introduce more artifacts due to the inverse telecine process than are removed by detection of bad edits etc."
So maybe it's trying to do spatial temporal de-interlacing when it doesn't need to (I once wrote software to do spatial temporal de-interlacing for a thermal camera, and you don't want that to be turned on when it's not supposed to be turned on). It mentions the de-interlacing in connection with a video mixer feature. So that's another possibility.
Anyway, that should keep you busy, if you want to fix it. ;-) Good luck!

While running on battery, MacBook Pro crashes after a few minutes of use.

While running on battery, my MacBook Pro crashes (shuts down) after a few minutes (less than 10) of use. Battery indicator still says I have enough power (more than 75%) so it can't be related to the other reported issues with low battery crashes.
While on power adaptor, I don't have any issues.
I checked battery condition as suggested in all the forum threads I can find and its fine.

PRAM reset did not resolve the issue

MacBook Pro (Mid-2009) shuts down while running on battery

Hi,
Five months ago, my MacBook Pro 15'' (2.53Ghz) started showing me the message 'Service Battery'. I took it to an Apple Store and I was told that everything is still fine. Nevertheless, for the past 2 months my laptop shuts down while running on battery (with 20% and 40% levels of charge) periodically. This does not happen every time.
Does anyone know if AppleCare covers this failure?
Is there any other way to fix this?
Thank you,
George

Mine does the same thing. May i suggest downloading istat pro to look at the health of your battery.
http://www.apple.com/downloads/dashboard/status/istatpro.html
Also do you calibrate your battery?
http://support.apple.com/kb/HT1490
I had never done that but after 15 months and 450+ cycles I was experiencing the same problem. I am a heavy user of my mbp 15" (2.4Ghz). After calibrating my health in istat which was going between 30-53 % Is holding steady around 65-mid 70% health wise. I have also noticed that my battery icon has gone from service battery to replace now to holding at replace soon for the time being.
I am not sure how many cycles you can get out of one battery but as far as i know 700ish is good. While i wish i was closer to an apple store (3ish hrs or more) i do hope i have helped you.

Temp fix to random shutdown (plug AC/remove battery)

I avoid this discussion board b/c of the hardcore fanboy-ism (rated members is a joke) but I want to drop off this temporary fix for random shutdowns:
Plug in your power adapter and remove your battery.
It seems to lock the cpu at 1ghz even at 100% load under the: "yes > /dev/null & yes > /dev/null" test.
I have been running this test for over 30min now with no random shutdowns where before I could not survive the 1 minute mark.
My cpu is now running at 1.0ghz/151F/100%.
Try for yourself and post your results.

Good News!
Last week I got a new logic board for my MB. After two hours working the MB shut down again!
I called Apple Care to get further informations and told them about the fix on macfixit.com the day before yesterday. And guess what... today my service provider have done the job!!!
I have made some tests right now... over 2h running with 100% CPU usage at 1.83 GHz. Bofore the repair it shut down after 1 minute under same condition.
It seems to be ok now. Tomorrow more reports....

Random shutdowns - IT'S THE BATTERY, NOT THE LOGIC BOARD!!!!

Hey,
Just got my battery replacement, and the shutdown problem is GONE. Here's how you verify - run your Macbook with the battery removed, on AC power - the problem disappears.
The tech told me that it is a short in the battery, which tells the PMU that there is no power (whether there is or not!)...anyway, I hope this is helpful to all of you!
P.S. If you're also getting the vertical lines at startup, that's a video driver issue - just zap the PRAM so you can boot, and once booted, change the resolution to something else and back to normal - it will fix the problem entirely.
THERE IS HOPE!!!!

<<<dear ASPs! this is -NOT- true!!!! it is NOT the battery!>>>
probably thanks to you my ASP (DataQuest, Zurich Switzerland) only replaced my battery and handed back my MacBook unrepaired.
After the "repair" the problem at first was rare but after just three days I'm back at normal frequency of random shutdowns. I have to spend another two weeks waiting for my macbook. this time I'm sending it to Netherlands
I guess that it's really that badly calibrated thermal module causing these shutdowns. obviously the thermal module is irritated especially if you use your macbook often - so after 1-2 weeks of repair time the problem is barely apparent. (which causes unsuccessful repair - "testing after battery replacement worked fine" says ASP)

HP Pavilion dv6-3050tx Overheating while Running Over Battery

I have an hp pavilion dv6-3050tx, Running Windows-7 64 bit. Few days back I had changed my battery as my earlier battery was not able to provide backup more than 5min. But after inserting the new battery I am facing a problem.
When I unplug the charger, after some time my pc get hibernated, and when I again turn it on it shows following massage
"The system bios has detected your notebook PC was placed in hibernation to avoid overheating.
The system is now operating normally and your data should remain intact.
Overheating may occur if the cooling vents are blocked or the operating temperature exceed the specification. The notebook PC should return to normal operation once the situation is resolved.
System Temperature (90D)"
I cleaned the fan and also applied thermal paste, but the problem is still there. And the main thing is, it happens only when the pc is running over battery, on Plug-in I have used my pc for 3-4 hours continuously and its running smoothly. But as soon as I unplugged the charger, the fan starts moving faster and soon after some time the pc automatically gets into hibernation due to overheating.
Again I am saying specifically that, this problem occurs only when the PC is running over battery. While Plug-in pc runs smoothly and properly.

Hi
This wat you can try.. install the Bios update from

Please zip up and attach your DSP project.
It looks like the column names in the data service metadata do not match. This can happen if you have manually modified the metadata in a dataservice. If you have changed columns in your database tables, it is safest to re-import, rather than manually modify the metadata.
If this is happening for some other reason, I'll figure it out from your project.
If you open a case with customer support, you'll have a better chance at getting this resolved as I'm going on vacation shortly.

Qosmio F40 - Random Shutdowns while gaming.

My Qosmio F40 has been crashing when I game. I'm playing either World of Warcraft or Warcraft3, and within 20-30 minutes the laptop just quickly turns off.
It won't let me power back up for about 5-10 minutes, and when it does it brings me to the black and white screen saying that it wasn't shutdown properly.
I've had no other problems with the Qosmio F40, I've been very happy with it.
This started happening about 2 weeks ago and has been consistent over those two weeks. I ran a 'Video Card Stability Test' and it also caused my laptop to crash. I've checked for new drivers and there are none available currently. My Video card came stock with the laptop and is a Nvidia GeForce 8600M GT.
I'm running Windows Vista (32-bit). I don't think it is getting over-heated because a few months ago I could seriously game on it for about 8-10 hours straight with no problems.
Any suggestions, any help/advice would be greatly appreciated.
Thanks,
Daniel

I completely agree with Maurice.
Fact is that a non-Toshiba graphic driver doesnt support the overheating protection and usages of any 3rd graphic drivers can leads to the overheating issues
In your case the notebook could overheats due to the dust and debris inside the notebook.
This could prevent the fans from rotating with full speed.
So try to clean the ventilators using the compressed air spray which is a professional tool for such jobs ;)

Bad Connection via Wifi while running on battery

Hi,
I've been quite happy as after a update of the Airport-Chipset my WIFI network has not to bee selected manually every time after coming back from standby - but I therefore got another problem - when using my WIFI on battery, I do have failed connections (TCP-Sessions) - I also assume packet loss or hard resets of the WIFI connection... as soon as I plug in the power supply, everything's like happy drugs and sunshine...
Anyone sharing my experiences?

I did more searching and found the answer. It isn't a battery issue but how well the micro HDMI cable fits into the laptop. Check out how to fix your cable here.

Getting seemingly random crashes while running Chrome

This has been happening for a few months. It starts with the tab I'm using in Chrome becoming unresponsive, then the whole browser. When I try to right-click on the taskbar to force quit the application, the taskbar does its 'genie' zooming motion, I click, and everything freezes in place. I then have to hold the power button down to do a manual restart. I normally have at least one other program open at the same time.
I tend to leave my computer (early-2013 MacBook Pro) plugged into the power cable a lot - I don't know if this could affect things. All my software is up to date, and I have anti-virus (Sophos) installed. Sorry I can't give any more specific info - if there's anything that could help, just say.

danajmu,
try disabling Sophos to see if that stops the random crashes. If it does, then uninstall Sophos.

Problems with random shutdown after replacing a swollen battery

Hello all,
Perhaps one of you can help with this issue.
I'm using a Macbook Pro 17" mid-2007 model. A few months ago, the power disconnected from the machine when the battery had already run down and the machine did a hard shutdown. When I booted it back up there were serious problems with the display. Eventually it stopped working altogether. I took it for service and it was determined to by the NVIDIA graphics processor problem, so Apple replaced my motherboard.
When I got the machine back from servicing, there was a rattle in the right fan that gradually got worse. After a while the touchpad button stopped depressing in the center. I also experienced several random shutdowns while operating on battery power. I learned about the swelling battery issue with macbooks and ordered a replacement. By the time the replacement battery arrived my original battery was quite swollen. I'm concerned that the swelling battery may have warped the case a bit, leading to the fan noise.
I have now replaced the battery, but I'm still experiencing random shutdowns after 20+ minutes of use on battery power. I have done the RSS tests that were recommended in other forums and there doesn't seem to be any random shutdown problems when I'm plugged in -- only under battery power. My understanding is that a swelling battery can sometimes cause the battery to disengage from the electrical contacts on the MB, causing a sudden shutdown. I'm wondering why the problem is persisting now with a new battery? After one random shutdown, I tried to power up again using the battery, while pushing the battery into place at various angles, but I couldn't find any angle that would give power to the machine. The fan noise is also still present.
Can anyone offer an explanation or advise on any methods to overcome these random shutdowns? I have checked the console and the machine isn't registering any error when it shuts down, although when it restarts it says "DirectoryService[35] Improper shutdown detected"

Yep, it is video (or: or audio for video) so unless you're sure you need it (because you work or will work with the DVC Pro HD video/audio codec), you can remove the plug from its' folder and put it in your documents folder (don't trash it, I have no idea if it is necessary for non-DVC Pro HD users to have it installed too).
The WWW is littered with posts from people encountering bugs and crashreports with DVCPROHDAudio.plugin as the main suspect. Most of those posts seem to be from video people rather than audio folks.
http://www.google.nl/search?q=DVCPROHDAudio.plugin&ie=utf-8&oe=utf-8&aq=t&rls=or g.mozilla:en-US:official&client=firefox-a
But, if you get crashes and you see this one mentioned in the report, disable it, restart, and see if the problem's gone.

Early 2011 MBP 17 Random Shutdown and Battery Behavior

Hi all, new to the forums here.
I recently purchased a refurbished early 2011 MBP 17' 2.2 Ghz i7 with 8gb and 10.7.5. Out of the box, machine looked great, but I noticed that the power cable was different than the one I had for my early 2011 MBP 15' I have for work. This raised an immediate redflag (buying from a refurb site outside of apple is always a cause for concern IMO) so I abstained from using that charger until I knew a little more. I plugged in the machine and booted it up and everything worked great. The batter was close to 100%, so after charging for approximately 20 min, I unplugged it, and the laptop immediately died. I powered it back on, and the harddrive began to spin for a few seconds, then the same result, total loss of power. Started up again, and I was able to boot into OS X and play around for a bit for a period of time before again, shut down.
For the next few days, same story. I was able to at one point, drain the battery completely and do a full cycle charge. The first time I did this, no change in behavior. Again, a few days later, I was able to drain the battery and perform a full cycle charge, but this time, a major change in behvior. Since the second full cycle charge, I have had absolutely no power problems. I haven't really "pushed" my MBP to see if fully utilizing the CPU/RAM/GPU will produce the similar results I had early, but it appears that everything is working great.
Here a few interesting notes to my situation.
When I was first operating the system (when plugged in, there were no shutdowns, only while on the battery) I pulled up my system report, and noticed that my battery cycle was very low (~5). This seemed odd, because I had opted for a used battery instead of a new one.
Prior to reinstalling Mountain Lion, my volume up key would trigger a few strange events. The screen for briefly get quite bright, then all open applications + the doc and widgets would restart (similar to killing explorer.exe in the windows task manager).
Since performing the fresh install, I have had abslutely no issue with my MBP and I love it, its a beautiful machine. However, as I purchased refurb, I'm hesitant to proceed (I will exceed my return period in ~2 weeks) without knowing my machine is in prime working condition. I have read issues about early 2011 models having issues with batteries and GPUs, but my symptoms were dissimilar to those described by others with those particular issues.
Any thoughts?
I have a genius appointment tomorrow evening for a general diagnostics check, but if others have experienced these issues, I would appreciate some input.
