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.

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.

Simple critical battery level warning script

This is a little script I wrote for use on my laptop. I wanted to have some kind of visual cue to let me know when the battery charge gets below a certain level and this is what I came up with:
#!/bin/bash
# Configuration
interval=120 #in seconds
critical_level=10 #percent
icon="/usr/share/icons/Tango/48x48/devices/battery.png" #notification icon
battery_id="BAT1" #ACPI battery identifier
ac_adapter_id="ADP1" #ACPI power adapter identifier
while true
do
if [ "$(cat /proc/acpi/ac_adapter/$ac_adapter_id/state | grep -o off)" == "off" ]; then
battery_max=`cat /proc/acpi/battery/$battery_id/info | head -3 | tail -1 | awk '{print $4}'`
battery_current=`cat /proc/acpi/battery/$battery_id/state | head -5 | tail -1 | awk '{print $3}'`
battery_level=$((100*$battery_current/$battery_max))
[ $battery_level -le $critical_level ] && \
notify-send -u critical -i "$icon" -t 15000 \
"Battery level is low!" "Only $battery_level% of the charge remains."
fi
sleep $interval
done
This script uses notification-daemon (or notification-daemon-xfce) package. It can be configured by editing values in the "Configuration" section. I just autostart it with my openbox session. It all should be pretty self-explanatory otherwise.
I hope someone finds it useful.
EDIT: Some improvements to the script.

thx, really cool i always forget to look after my battery percentage
maybe you can replace "BAT1" and "ADP1" with variables, so configuration would be easier
Thanks I made changes according to your suggestion.
moljac024 wrote:laptop-mode tools has an option of running commands when battery charge reaches a certain level. You could just run notify-send from there.
You mean in the auto-hibernate section? I use it as it was supposed to be used -- for hibernating -- and I think you can only set one command that's executed according to a specified battery level in laptop-mode-tools. Plus it would be sort of complicated, since displaying the notification depends on two conditions in this script -- specified battery level and power cord being disconnected.

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.

When display switches off I can't get it back without forced restart

When display switches off due to low battery power & I can't get it back even when I plug in to the mains and have to force the PC to restart.
Is there a pref somewhere to disable this?

Hello
When the display goes off exactly? How much capacity has battery at this time? 5%? More?
Try to set this to higher level.
When you work with your notebook and battery level comes to low battery level and the alarm alert will be shown in task bar but you will be able to continue your work several minutes or to connect AC power supply.
I am afraid your notebook reaches critical battery level and then is maybe too late for any action.
Set Low battery level to 10% and when the notification is shown connect AC adapter immediately.
I presume the display must not be off at all.

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.

Critical battery shut down - at 50%!!!! (T440s

Hi ,
I bought a new Lenova Thinkpad T440s (20AQ006VAD) 2 days back. System shutdown when the battery level reaches 50% and does not wake up without connecting charger. critical battery level is set to 5% on power options. Can anyone help me to fix the issue

Hi Nmshameem,
Welcome to Lenovo Community!
We understood that you are facing the issue with battery on your ThinkPad T440s.
To resolve this issue please open power manage and go to Battery menu and click on Battery Maintenance, you will get a new window and click on Perform Reset under Battery gauge reset.

Px4-300d shuts down/powers off while on UPS battery, regardless of remaining battery level

Upon line power failure, the UPS is instantly available to supply power to the px4-300d. The UPS is adequately sized to provide well over an hour of runtime during a power failure. The only way to have caching operate is to have a UPS connected. With the UPS connected, the NAS sees the UPS, the current power condition, and an accurate battery power level (%). Once the power fails, the unit begins its shutdown process and completes gracefully, even though the remaining power in the UPS battery is still near 100%. The whole point of having UPS backup is to keep the device running for as long as possible during a power failure, and then to gracefully shut-down the device should the UPS battery level reach a critical level and line-power still not restored. This is MANDATORY to be addressed in the next firmware release, or provide access to a configuration file that specifies the battery level percentage which triggers a shutdown. Why choose this "Enterprise Quality" storage solution if during a power outage it shuts itself down while everything else is still operating? Makes absolutely no sense.
Solved!
Go to Solution.

Hi easy-e,
What is the firmware version on your device currently?
LifeLine-based network storage devices should remain up and running normally using only UPS battery power until the UPS reports remaining battery is less than 3 minutes or below 5%. At his point, device shutdown will be triggered and your network storage device will gracefully shut down.
Have you checked to make sure it is compatible?:
What Universal Power Supply (UPS) models are compatible with my ix or px network device?
APC UPS not working with network storage device
If it is not shutting down properly, I would suggest contacting technical support to see if they can troubleshoot the cause of this problem.

Blackberry Z10 getting turned-off on 15-17% battery level

I have been using Blackberry Z10 for 2-3 month without any problem,but suddenly my mobile is getting turned-off every time its battery level reaches around 15%.
Suggest any solution to this problem.

Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
With the battery inside, connect your BB to the wall charger
Leave it alone for 2 hours, no matter what the LED or the display does
Remove the battery
Wait 15 minutes
Insert the battery
Wait another 2 hours, no matter what the LED or the display does
This has been known to "kick start" some BBs. If that does not help, then redo the process, but this time increase the wait time in step 4 to 2 hours, and perhaps as long as 4-5 hours.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
Obtain access to a known good and identical BB...use your battery in it and see what happens
The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
Good luck and let us know!

Help! iPhone 5 restarting by itself! Battery level won't change after charging.

HELP!
I have a 3 month old iPhone 5 that was recently updated to iOS 7. After a few days of use, I noticed after a night of charging, which I always do, the battery level indicator and percentage did not change. Next, in my carpool ride in to work, when using the iPhone, randomly the screen would freeze, then turn a random color and would shut off and restart.
Then all of a sudden it was fine, no issues.
Then today, the same thing is happening. The battery level, freezing/color changing on the screenscreen/restarting issues are back.
I don't know whats going on. Never had an issue with any of 3 past my iPhones.
Thanks in advance,
Josh

I'm sorry, it seems that the problem is that my phone WON'T restore. I just tried restoring again and it keeps giving me the 2001 error. Help.

Playbook stuck on 'Battery Level Critically Low' screen.

I know there's 100's of forums about the Playbook's battery problems. Just hear me out, please. Nearly 3 weeks ago, my Playbook died on me. It was stuck at 11% power, I tried charging with the charging it came with, nothing. When it went flat, I tried stack charging. No luck there either. Later, I bout a rapid travel charger, tried stack charging, nada. (I did get the LED activity and sceens the support page mentioned). Leaving it charging for a while, it was able to get the the home screen, but refused to charged. Since my Playbook was able to recieve power when connected to the rapid charger, I connected my Playbook via USB. I made a backup and I wiped the OS through the Desktop Manager because I thought my Playbook was bricked. My problem still wasn't fixed. I forgot that I still needed 20% power to install the OS, and since my Playbook refuses to charge, I'm stuck on a screen saying: 'Battery Level Criticaly Low' with a RED battery icon with a lightingbolt through it, with 0% on top of it, telling me to connect it to a power source, even known its connected to my Rapid Charger. I have no idea what to do now. Disconnecting the Rapid Charger immediatly shuts-off my Playbook. I also noticed something wierd. If connected to a Rapid Charger alone, when I disconnect it while a RED battery icon appears, it shuts-off right away, I don't get the icon telling me to reconnect. But when I have to connected to the Rapid Charger AND my PC via USB, I get an icon telling me to reconnect to a power source when I remove the Rapid Charger. My problem still remains. Even if a leave it charging while connected to my PC, and it boots-up, I still get the 'Battery Level Critically Low' screen. It still shuts-off when I disconnect the charger. Any tips? I've tried the Jump-Boost, stack charging and the 'Battery Characteristics' page wasn't much help either. My Playbook is still alive, I just need to find out how to make it charge. I'll draw a diagram of what's happening and post it here if you need it.

Assuming the rapid charger is the three pin magnetic type made by Blackberry, that charger almost always will charge a good playbook. Disconnecting the rapid charger should give the same red battery icon, but it doesnt. As it seems neither route will charge it I suspect the battery, the battery strap or the motherboard has a dry joint. If you cant get to it and find it by removing the back of the playbook, I would assume its days are over.
If so the backup will be of no use unless you can get another playbook.
Last resorts before getting out the spudgers...
Leave on rapid charger overnight. Press power button for 20 sec every so often next day whilst on charge.
Or
Leave connected to a non sleeping laptop usb overnight. Playbooks in standby will usually accept a trickle charge that way.

Caps Lock & Num Lock both lit. Pressed battery level indicator button on battery-full charge. AC adapter glows green.
Forced restart Cmd+ Ctrl+ Power. Normal boot. As startup items loaded, a Finder alert appeared. The alert read:

10.5.8 won't show UPS battery level

I just installed an APC Smart UPS 1000 VA UPS to my Mac Pro server. The USB cable is plugged in and the UPS battery is fully charged according to the display on the UPS itself. The Energy Saver control panel is the APC preferred control method (they do not supply software for MAC OS X after 10.4) and all the controls appear as expected with the exception that the Battery Level indicator at the top of the Prefs panel shows 0% full.
I've unplugged and plugged it back in to no effect. I restarted the server. I turned off the power at the wall switch and the UPS ran the server with no dramas for about 10 minutes. Nothing I tried had any effect.
There is nothing in the APC support site other than instructions for using Energy Saver panel.
Our power here has been pretty flaky this year and I want the server to gracefully shut down after about 10 minutes of an outage. It won't work if the UPS won't talk to the copmputer.
Steve

Have you checked to see if another USB device works on the USB port the UPS is connected to?

Photo in iPhoto Library Corrupted after forced Restart

Hi,
I'm a switcher. I've decided to switch to mac after contemplating for almost 6 months. I'm glad I've switched, the Mac is an excellent machine and Superb OS!!
Recently, I have encountered a problem while using iPhoto, Photoshop Element 2 and Preview together. (Please note that I did not tempered any files in iPhoto library. I have stored all my photo in My Documents which I do my editing using PSE 2 and Preview a pictures stored on the desktop). While dragging a file from My Document folder to the Trash, the Dock hanged! I quit all the apps and the dock is not responding and I decided to relaunch Finder by going to Force Quit and still no respond. I try restart the system but it hanged and I have to switch off the mac by pressing the button. When I re-sart the system and launch iPhoto, it prompted that "The photo library was created with an unreleased version of iPhoto" and I can't start iPhoto at all. It seems that some of my photo in the library are corrupted. Has anybody has the same experience? Would appreciate if anybody can help.
I've been playing my iMac for about 1.5 months already, and the only apps that I'm not comfortable is iPhoto. I've been using Picasa 2 on my Dell notebook to organize my photo and it's much more simpler and user friendly as compare to iPhoto.

Jonathan:
Welcome to the Apple Discussions and the Mac community. First, what I do whenever I have to have a forced restart of my Mac or have a kernel panic (dark gray curtain descends over the screen with a multiple language warning) is to immediately boot into single user mode and run the file system check (fsck). Here's how:
FSCK - File System Check
To start up in single-user mode
1. Restart the computer.
2. Immediately after the startup sound, press and hold both the Command (Apple) and "s" keys on your keyboard. The computer will display a series of text messages, at which time you may release these keys.
When the computer has started up, it will display a command line prompt (#). The computer is now in single-user mode.
How to Run the File System Check from the Command Line
Once you have reached a command line, follow these steps to use fsck:
1. At the prompt, type: fsck -fy (NOTE, there is a space between the k and the -)
The fsck utility will go through five "phases" and then return information about the disk's utilization and fragmentation. Once the check is finished, if no issue is found, you should see "** The volume <name of volume> appears to be OK."
If fsck alters, repairs, or fixes anything, it will display the message:
**** FILE SYSTEM WAS MODIFIED ***
IMPORTANT: If this message appears, repeat the "fsck -fy" command until this message no longer appears. It is not unusual for your computer to require several "passes" of fsck, because first-pass repairs may uncover additional errors. Run it until you get two consecutive times with an "OK" result.
3. When fsck reports that no problems were found, type: reboot
4. Press Return.
Now to your problem. It's more than likely that, as you expected, you have a damaged dB file in your iPhoto library folder and I doubt you'll be able to recover but we'll give it our best shot.
First run Disk Utility and repair disk permissions (also recommended after any software installation or update). Make a backup copy of the iPhoto Library folder (select and type Command-D). Now launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library. I would only select the option to rebuild the database.
If that brings it back you're on you way and can delete the backup library folder. If not and the rebuilt library is more messed up than the original, delete it.
Your best shot now is to launch iPhoto and when it asks to find a library or create a new one select Create. In the File menu select the Add to Library option. Direct iPhoto to your old iPhoto Library folder and select it for importing. That should get your photos back partially organized but don't know how much. You will lose album, keyword and comment information.
