Should an auto-shutdown because of critical battery change kernel_task usage at all?

I only ask because when my MacBook Pro 13" (Early 2011) 10.7.2, shutdown because of low battery, I put it on charge. The next day when I booted it up again it started running super-mega slow. The only reason I can find for this is kernel_task at 330mb, and about 300 % CPU.
It runs fine in Safe Mode.
The whole auto-shutdown is the only change I made between normal speed and claw-my-own-eyes-out speed.

Fixed:
Plugged in power supply and rebooted, now it works fine.

Critical Battery Level shutdown on desktop after CMOS replace...

So after speaking with an HP tech.. she told me to go buy a replacement battery and described how to do it.. no problem.. so i go ahead.. but find that my computer is still restarting with the "critical battery reached blah blah blah" business as before.. anyone else run into this BS???

somebody has to have some answers lol.. its happened everyday the last 3 days, today while i was in the middle of a playing a game. just shutdown, reboot with the "battery has reached critical state" message upon startup.. again, HP support had me replace the battery on the motherboard, did that, and its still happening.. not a notebook, a desktop.. make and model are posted above.. plz help anyone lol.. thx in advance.

Cannot lower Critical Battery Level in Power Options

I am wanting to adjust the Critical Battery Level in Power Options to something lower than the default 7% that HP has set. When I try to change the number, it will not save and it just magically jumps back to 7%. This means that my laptop will hibernate when the battery level reaches 7% and I cannot turn it back on unless I plug it into AC power. 7% equates to roughly 40 minutes of battery time and I find this setting way too conservative.
I have done some research on this issue and have found the following:
Some suggest that PC manufacturers will somehow lock this setting to an arbitrary minimum and the user cannot change it to anything below this minimum (it appears HP have set it at 7% in my instance).
This link suggests using power.cfg and the command line to make the changes How To Lower the Critical Battery Level to 1% in Windows 7
Steps I have taken to try and resolve this:
I have tried the powercfg.exe method described in the aforementioned link to change the critical battery level to 3% and initially it appears to work. When I open up the Power Options screen, it indeed says 3%. However, when I actually test it out by using the laptop, it will still automatically hibernate at 7% battery level - it simply ignores the 3% setting.
I have also tried using powercfg.exe to change the Critical Battery Action to "Do Nothing" and likewise this setting is ignored and the laptop hibernates anyway.
I have phoned HP support and the only useful information that I got from them so far, is that the PC manufacturer has set it to 7% and it cannot be changed. They said they will escalate this matter to the research team and give me a call back.
I phoned Microsoft support and the consultant seemed to be confident that he could fix the issue but would not divulge the answer because he said that doing so would void the HP warranty and he didn't want to be to one to do that. He suggested that I call HP and request a conference call with Microsoft and they could then fix it. He seemed to be of the belief that if HP has set the 7% minimum that they should be the one to remove the limit.
If nothing works, I wonder if completely formatting the laptop (including removing the HP recovery partition) and then reinstalling a different Windows 8.1 (or Windows 7) will let me have full customization of the Critical Battery Level?
I would really appreciate your thoughts on how to fix this. It really fustrates me that HP thinks they know better and that the user needs to have 7% battery reserved - it is such a waste not to be able to utilize a battery to its full potential.

Hi @Sparkles1 ,
There must be an alternative solution to this.
What is the reasoning behind HP locking this setting at 7% minimum? I understand that a battery should not be run down to 0% as this will damage the battery but 7% is unreasonably high and in fact this does not conform with ACPI standard specification. I refer to the following document: https://msdn.microsoft.com/en-us/library/windows/hardware/dn481320%28v=vs.85%29.aspx
In particular, please see the table where it says that the critical battery level must be set to a value between 0 and 5%
Can you please advise how to change this? I believe this is a software related issue (specifically, the battery drivers). Can you issue an alternative driver to install? If you insist that it cannot be done, I will have no other option than to return the laptop and request a full refund.

HP Pavilion g6 Notebook - Sudden shutdowns without warning when battery is low

My notebook is only ten months old. Within the last week, it started shutting down unexpectedly when the battery was low (but not at a critical level). If I try to restart it, there won't be a response until I plug in the adaptor cord. Usually there will be around 20% of my battery left when my computer is booted up after such a shutdown, so I don't think it's because of my battery being low. (Besides, when I've accidentally used my laptop until it has to hibernate, the light next to the port for the adapter cord usually blinks to tell me it's the battery.)
Initially I thought it was a problem with overheating, so I cleaned my vents and bought an external laptop cooler when it first shut down unexpectedly two weeks ago. However, the shutdowns have become more frequent since then. I've run the Memory Diagnostic Tool, the HP Battery Check, and updated my BIOS. No problems have come up; in fact, everything seems to be running perfectly. I also ran AVG and Malwarebytes Anti-Malware. No problems there either.
What could be the problem? Thanks for any help!

Mines started doing exactly the same! Its just 12 months old though and hardly ever gives me a low battery warning. Then it will turn off without shutting down the proper way. When I plug in and turn back on, the battery says its at 20-25%
Is there actually a solution to this and whats causing it?..because if it's the battery then **bleep**..they don't last long.

Critical Battery Level reached, forced restart on my desktop

Hello all. My HP Pavilion e9180t will suddenly shutdown and restart at random times. Upon restart it says that it was shutdown due to the battery reaching critical levels. I spoke with a representative over the phone and she had me change my CMOS (?) battery. So i bought one and replaced that, its still happening though. Any help would be fantastic..

Hi,
Remove the battery and check the voltage with a volt-ohm-meter. It's possible that the replacement is not at 3+ volts. At 2.5 volts you might start seeing issues and at less than 1.8 volts the battery is at the critical level.
You should be using a lithium CR2032 battery. You might see close to 3.3v on a fully fresh CMOS battery.
If your PC is running on UPS then this could also cause an error message. Check the electrical power to the UPS and/or by-pass the UPS to determine if the UPS is the issue.

Critical Battery Suspends Incorrectly

I'm using gnome-power-manager, and my computer suspends wonderfully. I'm not sure which method I'm using since I tried both and I cannot recall what I did on my last effort to get suspend/hibernate to work. However, after my laptop suspends for being idle, charges down past critical battery level, I start it up. I made the critical battery level mark 5%, by the by, so that it can suspend for a good while without me noticing.
Anyway, I start it back up at a power level bellow critical and it doesn't complain. This is one issue. I feel like this behavior is the wrong one. Can someone explain to me why it is not or why I should look at it another way? Or should something be filed upstream-ish/to the package manager?
As I leave the laptop on and plugged in, the battery charges. Upon reaching the 5% level, it tells me my battery level is critical and suspends. This is just plain wrong. If I'm charging and the battery level goes critical, it should not suspend. I feel like I should post this to the package manager of gnome-power-manager. Thing is that I don't quite remember which package that is. Truly, I feel like I should post this to GNOME, but I think there's a pecking order for these things?

Both these issues sound like valid bugs to me and I would certainly up-stream them - especially the second.
Arch is a pretty raw distribution in so much as it makes little or no modifications to the up-stream packages. This will typically mean that you can report issues with packages directly up-stream - which most developers would prefer. But you are right - if unsure it is a good idea to check to see if it is a distro specific issue first.

One application "failed to quit" on auto shutdown

This has been happening daily now for perhaps a month, and it's got me stumped. I can't identify any pattern or anything.
I have my system scheduled to shutdown overnight and start up in the morning, and have had this same setting for years. What's happening lately is that the unattended shutdown apparently times out and I get a message saying logout failed "because the application [X] failed to quit." Now the really weird bits -
'X' is almost literally a different application every day, and it's rarely if ever attributable to an unsaved document. I think it's happened at least once with every single one of the applications I regularly have running. Sometimes it's an application I've used in the course of the day, and other times it's one I haven't touched. But it happens every day.
if I manually select the shutdown menu command at any time, including after finding that the auto shutdown has again failed, the shutdown runs smoothly with no application failing to quit.
I've run 'repair disk' in Disk Utility and also Disk Warrior and applejack several times each, as well as a weekly scheduled batch of maintenance tasks (using Cocktail). None of these operations has changed the behaviour come shutdown time.
Has anyone else seen this? Solutions anyone? Thanks.

I'm 'bumping' this one.
Still happening very consistently, and becoming a real problem. Since originally posting I've run all the disk operations many times over, as well as one or two system updates at least. Nothing has changed, it just happens like this every night.
The only thing I can offer as a (sort of) pattern is that the application that's most often the one reported as preventing logout is HistoryHound. And it would appear to be one of the first ones the system tries to quit in its shutdown, since most of the apps are still running. However it does still vary - it happens on a different app sometimes, and it happens on some app when HH wasn't even running. So not sure that's much of a clue - unless perhaps certain apps are taking longer to quit than the system expects (or something??? - scratching for clues here ...... )
Can anyone help? Please ....

Safari Auto Shutdown in Yosemite

Hi All,
Ever since I upgraded to Yosemite, my safari will auto shutdown itself. There is not telling when it will auto shutdown but usually if I left it open overnight or during the day. I'm not sure if its considered a crash because usually a crash window will prompt telling you the app has crashed. I have at least 80GB free space and my iMac is only a year old therefore it can't be hardware problem. I would have other apps like iTunes and iPhoto or Mail opened and they stay open throughout.
Anyone has the solution for this?
Thank you!

Hi Patrick,
Thanks for the info. Just tired it and left over night and still Safari disappeared when I check in the morning.

Auto shutdown SAP

Hello Guys,
I want to configure SAP System in such a way that whenever UPS Battery goes at minimal battery state (For Ex. say battery power left 30%) my Server should automatically gets shutdown by safelly shutting down SAP Application and Oracle Database.
Below is my SAP System Details:
Server Hardware: HP DL 380 G4
SAP : ECC5
Database: Oracle 9i
Please guide me to configure such things.
Regards
Tushar.

Why involving SAP on it?... You can configure your smart UPS to take certain actions when this things happen... Just configure your OS to trigger a script that shutsdown the DB and the system under that criteria.
Regards
Juan

X1 12942PG: Critical battery issue

Hi, i've recently buy a Lenovo Thinkpad X1 12942PG and since i've begin to use it, the thinkvantage toolbox showed a message about a critical battery problem ("problème critique de batterie" en français) and asked to install an update on this website, i've installed the 2 updates regarding the battery, and it changes anything.
What can i do?
Thanks in advance
Moderator Note: Edited subject to match content.

do a battery reset in the Thinkvantage Manager, if that doesn't fix the issue, then you should call the warranty department, as you would need a new battery.
I had a battery replaced due to some issues with the battery.

Auto shutdown feature

hi all i'm a newbie here...
i wanna ask you which bios menu will enable us to disable the auto shutdown? i keep failing occt though the temps were only 65C! my motherboard is MSI 890FXAGD70

Quote from: Jack t.N. on 30-July-10, 16:39:46
That was a thermal shutdown then. This is a safety mechanism to prevent CPU damage due to overheating. Trust me, you do not want to turn that off...
Better work on your cooling solution.
you know what? i believed it too because its an alarm to warn us right? but say, what is the menu for doing that? just curious

Because of low battery my iphone 5 got switched off and than its not starting by pressing the power button or by keeping it on charge. While charging a white screen comes for 2 second and goes away. This process continues till the phone is on charge. Please suggest how can I start my phone.

Hello Ritugor,
I would be concerned too if my iPhone was not powering on. I found an article with steps you can take when you encounter an issue like this. I recommend following the steps below:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

Macbook pro auto shutdown

my work need win7 system,so i get a win7 ultimate
recently i find out when i run some applications for 3~4 hours in win7 system,my macbook pro auto shutdown...even the power adapter is on,the battery still run out.
this never happened in my macbook pro before when i use leopard or XP system

Thanks for taking so much time in helping me.
Just an update:
2 loops/passes done - no errors.
Called up Digital Hub and talked to the technician, he says there are 3 possible problems:
1. Battery (which is still inside the laptop) may cause some disturbances with the electric current
2. Software related - most likely re-formatting may be needed
3. Video card may have failed, which means complete change of the logic board ----> worst case
I'm crossing my fingers that it's either of the first two.

Should an auto-shutdown because of critical battery change kernel_task usage at all?
