Battery status + Speedstep Centrino

I recently bought an Acer TravelMate 4501LCi and I am really happy with it, except that it seems not to be able to determine the current battery strength. I have acpi and acpid installed. I also have acpi listed in the modules array and acpid in my daemons array. Does anyone know how to get it working?
Another question: How do I enable Centrino's Speedstepping in Linux? /proc/cpuinfo alsways reports 1500MHz so I guess it's not working correctly. Maybe this also has something to do with acpi?

You must enable the correct cpufreq modules in the kernel(take the latest kernel).
Cpudyn just slows down the CPU even when on AC, and speeds it up when it works. It also manages you hd spindown.
I would say your probem is a matter of correctly configuring you kernel.
Also try to upgrade your BIOS if available.
I am certain that I have the proper stuff built into my kernel. (Yes, I have enabled development code and selected config_centrino_acpi). I didn't really like cpudyn either.
Right now I'm running the ondemand governor, which works fine, but I still cannot modprobe speedstep_centrino. Official docs @ intel.com say you have to load it before acpi, but then I get a no device found :S. If I load it after modprobing acpi, I get a device or resource busy. I guess something's just buggy. (either the driver or my BIOS). I will try to upgrade it when I get home.
Btw. I heard smartbattery support won't be in the kernel until 2.6.12, probably even later .

How to reset battery status in menu bar?

After upgrading to 10.5.5 I experienced sudden loss of performance with both of my batteries.
Overnight the battery yielded only 45 min, and the recharge time was usually about 40 min as well.
As a result of frustration, I decided to crack open the case of 1 battery and connect a 12V 20W bulb to fully discharge the battery.
Possibly as a result of the deep discharge, the battery took 6 hrs to recharge, and now yields approx 3-4 hrs of power.
HERE IS THE PROBLEM. The battery status in the menu bar does not seem to reflect the battery's newly found performance.
It keeps says "40 min." left, and when it runs out of minutes, it displays: "Calculating ... remaining"
The same odd behaviour occurs when charging the battery. It says: "35 min" to full charge, and when it runs out of minutes it displays: "Battery finishing charging"
MOREOVER, yesterday, the low level power indicator appeared, but the computer kept working for another 1.5 hrs before going to sleep.
Finally the System profiler shows this information
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1661
Remaining Capacity (mAh): 1361
Amperage (mA): -1203
Voltage (mV): 11441
Cycle Count: 71
After the deep discharge, the Full Charge capacity jumped form 640 to 1661.
That's good, isn't it?
But how can I reset the battery status in the menu bar to reflect the actual performance of the
battery? Or did the deep discharge damage something?
Regards

I talked to Apple repeatedly and they refused to replace the battery in spite of the many good arguments I brought forward. Their only argument is that the battery is old (was shipped in 2006)
I even requested them to ask their own technicians whether
it is normal for a battery with only 71 cycles to discharge so soon.
My request was declined.

Storage 6180 - Both controller Battery status is Learning

regards,
AnwarA non authorative 'guess' is that the controller is attempting to learn the rate of discharge of the battery. It needs a little time (maybe quite a few hours, even a day) to do this.
Batteries are a weak spot of things.
Get prepared to replace the battery .... otherwise I suspect (and I know not the 6180 specifically and I am not bothered to look it up, you can as well as I), the appliance may degrade and run a little slower.

HP Battery status changed from "Weak" to "Replace"....

Hi,
I had purchased HP Laptop dv4-1211 TU in India in 2009. Now i stay in US. Recently few days back, i checked a option " HP Battery Check" in my laptop. When clicked it said my battery status is "Weak". I didn't bother much. But today when i checked it back it said " Replace". How do i go about this?
My queries are:
1. Is it safe to use my laptop in this condition?
2. Battery gets heated up too much after this, so do i need to replace with a new one or can i plug in and use it, i.e i meant on AC power and not battery alone?
Waiting for the response from u.... pls help me....

Hi sweety2222!: most laptops that use batteries can also use AC as well
but to be sure I'd check the manual the manual will also tell you if you can replace it, the type of battery & how to replace it as well
good luck
hope this helps you

Speedstep-centrino in beyond doesn't work

Hi, I have Arch running on an inspiron 9400 with a core duo. If I boot into the normal arch kernel, cpu scaling works fine. But, in beyond it keeps saying:
FATAL: Error inserting speedstep_centrino (location of *.ko file): No such device
when I try to modprobe it. acpi-cpufreq does the same thing.
I'm not sure how to get more verbose output, but the device does exist as scaling works in the non-beyond Arch kernel, in ubuntu, in suse, and in windows.
Any help would be appreciated.

I've tried acpi-cpufreq and it does the same thing.
Also (it might be related) networkmanager from aur can't find any network devices while in the beyond kernel. This all works in the regular kernel though. Normally, I would be just fine using the regular kernel, but beyond supports the suspend to disk and the suspend to ram where I can't seem to get either working in the regular kernel.
I originally had the speedstep-centrino in the modules array and that's where I discovered the problem. Both speedstep-centrino and speedstep_centrino have the same problem. If there are others that have this working though, maybe I could just try and reinstall arch again and see if I have the problem again.
LB06: your problem is different, I'm getting a No such device error while you are getting a device busy error. n3rlynx might be right about your problem.
Thanks for the replies.

then i need to switch off and switch the iphone. per day i'm doing this for 3 times.
mean while if some one calls ,its not displaying who is calling.

Hi Tarun 49,
If you are having issues with your iPhone such as you describe, you may want to try some things to troubleshoot.
First, quit all running applications and test again -
iOS: Force an app to close
Next, I would try restarting the iPhone -
Turn your iOS device off and on (restart) and reset
If the issue is still present, you may want to restore the iPhone as a new device -

Thanks for using Apple Support Communities.
Best,

Battery status won't hit 100% anymore

I've had my PB about a month and a half (got it new believe it or not) and recently I noticed that even though the battery status will say "charged", the percentage will not show 100% when plugged in. At first it was 99% and now it's 97%. I've calibrated my battery and try to let it run fully down every once in a while.
The battery info in profiler shows this:
Full Charge Capacity (mAh): 5309
Remaining Capacity (mAh): 5183
Is this normal or should I be concerned or what?
Thanks everyone.

That doesn't sound out of the ordinary. See this Apple note: http://docs.info.apple.com/article.html?artnum=88344

Missing Blackberry Battery Status Indicator

I've looked all over the web, my instruction manual, the index inside the phone, and in still cannot find the meaning of this symbol in the middle of my battery bar. From what I've seen on the internet, its as almost as if it does not exist. I would probably believe so if it was not for the fact that I am staring at it right now as I type this. I have had problems with the USB port on it before and I am pretty sure that has something to do with it. Also when Its plugged into the computer and the port and USB are finally working in unison, the computer says that it is malfunctioned.
The icon appears when I've tried to connect to it to a computer or even sometimes to an outlet. It looks like a C or parentheses with a scrunched up 3 sort of like this:
C 3
or
( 3
I was surprised that no one else has seen or inferred about this icon and even more surprised that a complete index of all battery status indicators would exist; including those for malfunctioned or damaged batteries. Any help or recommendations to help me solve this problem is greatly appreciated.

Hi silvaback75
Can you send us a picture of this icon?
Thanks

Nokia e7 - belle update battery status

Hi
i upgraded my nokia e7 to nokia belle recently and I was very excited but after the update I found out that there no longer was a battery status showing the percentage left. I really liked the old battery status so you would know how much battery life is left. It is just a bit weird that a very good thing from the previous version is discontinued on the belle version. I'm sure many others would agree with me on this..
Solved!
Go to Solution.

the battery level in the new structure has the same 7 levels... you can check it out just like that... not necessarily you would need a visible info on the battery level
anyways
All 7 parts filled up - 100%
6- 80%
5-65%
4-50%
3-35%
2-20%
1-10%

Battery Status Indicator (in menu bar) does not update

I've recently noticed that the battery status indicator in the menu bar gets "stuck," and won't update. I can force it to update by disabling and re-enabling it, or by changing the view style, but if I leave it alone, it won't change, even across sleep/wake cycles.
Any ideas?

Actually, the problem disappeared after a reboot. I reboot so infrequently, I didn't even consider that as a solution, but something else caused me to need to reboot, and after that, the indicator works fine.
Still no idea what caused it to get stuck in the first place, but for now, it's better.
Good luck!

Default color is displayed for time, cellular and battery status‏‏

Hi all.
I'm using non-default background color for my page. Time, cellular, battery status have default color (system theme). How can I change this color?
I wrote in Page.xaml:
<Page
Background="#FFE5E9EC"
Foreground="#FF000000"
/>
But it doesn't work.
My example:
Skype example:

Set ForegroundColor property of StatusBar. Try following code
StatusBar statusBar = StatusBar.GetForCurrentView();
statusbar.ForegroundColor = Colors.Black;

(SOLVED) Conky and battery status

How come this will not work on my system:
${color red}$alignc Battery Information
${color lightgrey} Currently: $battery
${color lightgrey}$stippled_hr
I have tried a dozen scripts for battery status and nothing works. Does anyone have a sure fire way to get some status from my battery?
I am using a netbook, pretty standard stuff. I don't know why it won't work. I tried other commands and one returned "U" for unknown battery status and what not. How can I find out what is going on?
edit:
Battery: ${battery_percent BAT0}% ${alignr}${battery_bar 8,70 BAT0}
This displays 0% and an empty bar.
I went ahead into /proc/acpi/battery and found BAT1 and no BAT0, so I changed the script and I get a percent now...
This may be solved, but I am going to try the other functions to see if I can get the output I wanted in the first place.
Why does Conky hate batteries?
Last edited by Google (2010-07-02 07:16:26)

"$battery" does not work because it assumes as default BAT0, which you don't have so it will have to be "$battery BAT1". See "man conky" for more info....

Battery status not updating

I have recently replaced the battery for my IPhone5 after a crash. After that the battery status indicator is not dynamically updating. It updates only after every restart. I tried resetting all settings, updated to recent IOS7.1, restored several times. But of no use. Please guide.

Hi,
I have the same problem with my now replaced iPhone 3G with iOS4...
I have this problem, when I charge my iPhone 3G with the charger, that was supplied with my iPad. And also the problem can only be solved, when rebooting the phone.
When charging, the symbol shows the "flash"-sign in the battery to show, that the iPhone is charging and the symbol changes to the wall-connector-symbol, after the iPhone has fully charged. But when disconnecting the charger, the battery-symbol still shows empty, until I reboot.
The problem occurs with the iPad charger, but it does not occur, when charging the iPhone inside my "JBL radial" soundspeaker-system.
So I think about a bug in iOS4
Regards,
Florian
