Extreme power consumption after upgade to10.3.1.1581
After upgrading tried new features regarding picking up phone and activating screen, battery would drain after 4 hours, of limited use. Checked device utilization, BlackBerry blend at 50% utilzation. Disabled the new features, and dimmed screen. Seems to be behaving normally now. Did not enable BlackBerry blend just went into app to see what it was.
Hi and Welcome to the Community!
As with all updates, resource consumption will be unusually high for the first 48-72 hours, after which it normally settles down and behaves properly. Sometimes, a few hard reboots during that timeframe help it along. But, any judgement about resource consumption must be held off until after that initial settling in period has passed.
Good luck!

[SOLVED] Huge power consumption after kernel upgrade.
Dear All,
I have recently bought the new lenovo thinkpad X1 equipped with a Core I5 processors and 4GB of RAM.
I am quite satisfied with this machine except for the fact that the fan is extremely loud (but perhaps a bios upgrade will fix problem).
Now my problem:
When I first installed Arch (first days of August) I ran powertop and the power consumption was around 10 Watts when idle with wifi card turned off.
Now, after some upgrades, the power consumption raises to 18W in idle and consequently the battery lasts less than 2h.
Here my current configuration:
Linux think-x1 3.0-ARCH #1 SMP PREEMPT Tue Aug 30 08:53:25 CEST 2011 x86_64 Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz GenuineIntel GNU/Linux
and here the powertop output obtained with the cpu frequency governor set to "On demand":

I have also tried to disable most of the running daemons and unload some modules, but I have never got less than 14/15W when idle, which in my opinion is definitely too much!
As far as I'm concerned, the kworker process is responsible most of the wakeups.
Any ideas?

Dave Jones 2011-08-03 15:32:21 EDT
enabling it by default in 3.0 caused regressions for some people, so it was
disabled. Hopefully Intel figures it out, and we can switch it back on by
default in 3.1 / 2.6.41 (until then, you'll have to set it by hand).
Interesting stuff, also recommend this thread on phoronix:

High power consumption after update
I recently updated all my packages (it had been a few weeks since I had done this last) and I've noticed my power consumption has jumped dramatically. Before I would average around 13.0W and now the baseline seems to be about 18.5W. I use laptop-mode-tools.
I'm happy to post the output of any command but didn't want to spam as I'm not sure what would be valuable.
I have looked at powertop, but without being able to compare to the past I'm not sure how to diagnose this. Any suggestions or pointers would be greatly appreciated.
I have a Thinkpad T410: Linux alpha 3.11.2-1-ARCH #1 SMP PREEMPT Fri Sep 27 07:35:36 CEST 2013 x86_64 GNU/LinuxIt's possible I suppose that it is related to audio codec power management. After I upgraded I had to add myself to the audio group to get sound working again. I also noticed snd_hda_intel is always pretty high up in powertop.
Finally, I use laptop-mode-tools, and it appears audio codec power mgmt isn't working by default. I can manually select it to turn it on. I also saw this output in journalctl:

Higher power consumption after suspend
Hello,
It seems that my power consumption is significantly higher after resuming from a suspend than before. I suspend with the systemctl command. Measuring the battery usage (with powertop or looking at /sys/class/power_supply/BAT0/power_now on my laptop), I get the following numbers :
- 6-7 W before suspend
- 10-11 W after
Those number are quite stable in time, in particular the higher consumption stays until shutdown. I have tried looking at the power decomposition of powertop, and it seems that the backlight display consumption is indeed higher, although I keep the same luminosity level. I tend to consider the decomposition usage by powertop as a guess estimate anyway, so I am not sure whether this means anything.
Any ideas on how to solve this issue, or how to investigate further on?
Cheers,
GuillaumeHave a look at powertop before and after suspend. I noticed that some power saving options get turned off when suspending. I don't have a solution though.

Dramatically raised power consumption after OS upgrade
Hello,
I have model 8820, and after I upgraded OS version to 4.5
using this sw: 8820M_PBr4.5.0_rel75_PL2.7.0.66_A4.5.0.52_Orange_Slovakia.exe
power consumption of my BB raised dramatically (it is 1 day between charging instead of 6 days with previous OS version)
also when I use BB regularly appears (each ~3 minutes) wait cursor for ~2 seconds
Can anybody help with this?
thanksThis is very unusual from 6 days to 1 day!!! It should not be as such.
From where did you receive the OS? Is it from your carrier's OS download site?

I915 power consumption issue after switch to systemd?
After switching to systemd I noticed a massive increase of power consumption on my Thinkpad X220 (i5 Sandy Bridge).
The strange thing is, that after some reboots it randomly seems to catch the i915 power saving mode and the consumption gets from ~24W to ~7W at idle. But only after several reboots.
Adding the good old i915.i915_enable_rc6=1 to the boot parameters doesn't make any differences. But looking at the powertop detail outputs it seems to be a i915 issue.
Using the latest linux kernel from core (3.6.4) and latest intel drivers (2.20.12).I started to get suspicious because I have only ever had the issue in my office. Last week, when I encrypted my drive, my machine wrote to disk for more than 14 hours solid. I then did all the set up and all the restoring from backup etc. with no issue whatsoever. Lenovo ran the thing for 48 hours straight with no problem. But once in my office...
So I asked the local IT people if they could think of anything other than overheating and explained the issue. They took my laptop yesterday , booted it from a hardware testing CD and ran it for a couple of hours sitting on top of a hot computer in the server room which is definitely hot. (It has a whole bunch of computers, I guess.) No issue. They then ran stress tests for a while in the same place. No problem. Highest recorded temp: 65C.
The head of IT then took my power adapter to a more general IT service to be tested and inspected. They looked at it, they opened the plug to check the fuse, they tested it. No problem. Of course, the guy also explained why he was asking and the other IT person said, "Oh, is that on level 1?" "Yes..." So apparently there was another machine (a Mac), I think, doing just the same thing in an office in my part of the building. Testing showed that the power spikes and when the power spikes, the laptop shut down as a safety measure. Solution: they installed a UPS for that one laptop. They didn't tell anybody else, including the local IT people.
What the local IT people were going to do was to install equipment to monitor the power in my office and see if anything weird was causing my laptop to react. However, that was when this was an extremely-unlikely-but-we-are-getting-desperate-for-theories scenario. Clearly, that theory no longer seems wildly implausible at all. So the current hypothesis is that it is most likely that my machine is also reacting to the spikes in power by shutting itself off. (I'm not sure why it should have just started doing this but who knows what the state of the electricals is and how that might vary?)
I have been told that a surge protector will do no good. (They've given me one anyway but apparently it will not deal with spikes in phase 3 power or something - I didn't understand this bit but the head IT person said he didn't understand it either but the electricals IT person showed him with graphs on the whiteboard. So it must be true.)
The current plan is to try to get the UPS from central IT which was provided for the other laptop since that person's discipline has since moved to another floor of the building so the UPS probably went back to central IT. They are going to ask during a meeting tomorrow about this possibility. Otherwise, they are planning to order a UPS for me on Monday.
I'm somewhat surprised that the abrupt shutdowns haven't screwed my data. I've lost work but not seen fs corruption. I didn't take my laptop today. I'll need it next week but I do not plan to plug it in in my office until I have a UPS.
I'm pretty annoyed, to be honest. I've wasted hours on this and got incredibly stressed about it. The IT people have also wasted a (smaller) amount of time. I hoped to have a new draft of an article I'm working on written by the end of reading week but that didn't happen due to all of this. And they *knew*. It would be different if this was an unknown problem just discovered - of course, one could understand that. But there's a known problem which can cause this type of problem and presumably could well damage equipment without these sorts of safety shutdown features and they don't tell anybody.
And, no, I doubt very much indeed that a damaged personal machine would be considered the institution's liability. (Maybe if it was a student's machine and the student was required to use it or something but even then...)
I can't believe it does much good to their equipment either.
The local IT people did know there was an issue with some burnt out devices but that was about eight years ago and only got mentioned as a outside possibility when other diagnostics turned up no result.
What gets me is that the proposed solution will only solve the issue for me - not for anybody else in my part of the building on level 1. -
What is the power consumption of airport extreme
I have bought a time capsule which is fits close to my TV and HIFI but I realized it gets really hot, would I have a similar problem with Airport Extreme or is power consomption lower ?
The TC has a maximum power consumption of 34 watts; the AEBSn uses around 22 watts. Both will run "hot" as they employ large heat sinks just under the top surface to dissapate heat. It is important to allow for enough area around either base station to allow for an adequate exchange of heat from the device to the surrounding air.

I have a Nokia N86 which is 2 years old.
I have been experiencing a problem with battery drainage since I bought it. The battery meter suddenly drops from 5 bars to one bar when I browse the net using HSDPA, after about 30mins or so, when the phone is already hot. I sent it into service once, because it happened very randomly and it did not look like a major issue. They said they recalibrated the battery. After a week of somehow uniform battery draining, the battery started going flat suddenly, again, from 5-6 bars to "low battery".
I went to a service center again to check if it's the battery or the phone. Nokia Energy Profiler says that the current is about 400-500mA when using HSDPA. The engineer at the service center connected a power supply with measurable current consumption, and during the usage of HSDPA, the current was at least 800mA, with almost 1000mA peaks. He said that these current intensities damage the battery in about a month and that he would not recommend changing the battery, but the HSDPA chip. The warranty period expired a month ago.
I am asking you guys:are these values normal? 800-1000mA during HSDPA usage for a Nokia N86? I need a serious, valid opinion from somebody who really knows mobile hardware. Thank you.This has happened to me every now and then. First it seems as if the battery is almost full and then it's suddenly empty even without using the device much.
Sometimes the device feels warm. In those cases I just reboot it.
Obvious things to check would be that BlueTooth and WLAN are off if you don't need them.
Sometimes the switch of the kickstand has activated when I have carelessly thrown the phone on a bed for example. If you have defined it to start an application that could cause some power consumption.
I haven't tried to measure my power consumption. I guess there are two options:
- the device actually consumes a lot of power sometimes
- the battery indicator isn't always up-to-date i.e. it shows several bars when the battery is actually almost empty.
It's a shame because it's a pretty nice phone and I quite like it. Luckily it's quite a rare problem.
(But not that great if the battery dies during a bicycle trip just because I have SportsTracker running.) -
Extending Power Consumption by Day report to more than 31 days
Hi
I need to provide some information to management about computer activity on different days of the week in our environment. My first thought was the Power Management reports in SCCM and the 'Power Consumption by Day' report seems to fit what I'm after pretty
well. The only problem is that the report only covers a 31 day period and I need to increase this.
I found this line: set @reportStartDate = DATEADD(Day, -31, @reportEndDate ) in DataSet one for this report and assumed I could just increase the number from -31. However, when I attempt to edit this, or indeed edit any part of this report,
when I try to save it I get an error:
'More than one report item in the report has the name 'image1'. Report item names must be unique within a report.'
As I mentioned, this error appears if I try to edit and save any change within this report whereas I can do the same on other Power Mangement reports no problem. So it looks like an issue with this particular canned report.
Does anyone have any idea how I can get round this? As far as I'm aware the report files are not available in a directory on the server but are stored in the database so I wouldn't know how to go about looking for this duplicate 'image1'.
If there is an alternative solution that doesn't involve using this report I'm open to anything.
Thanks in advanceActually the power management reports are stored on the site server. They can be found under <Install director>\Reports\Power Management within the cab file. You can exact them and edit them.. I recommend that you made a copy of
the report and don’t over write the existing report.

Great, I'll try looking there.
Thanks Garth -
Massive power drain after Belle Refresh update on ...
Hello
From being a minor annoyance the massive power drain from my N8 after Belle Refresh update is now a big problem!
The battery does not even last a full day now
No apps running - power save on, but to no avail.
After advice from Nokia Support I've tried to reinstall Belle Refresh again from Nokia Suite, but it didn't make a difference.
What else can be done? Is it possible to uninstall Belle Refresh completely?
Some have suggested it is because of the weather widget. Any confirmation from Nokia on that issue?I have Belle refresh for over a month now and I keep running the weather widget permanently on first screen. Overall the power consumption is the same as before on Anna (I skipped the first Belle incarnation).
The only particular thing here is that I flashed clean the full 111.40.1511 version for my phone language. All I can tell is that in the first days after flashing the power drain was significant, merely because of intense phone usage, part of various customizations or just by curiosity. Since then the power consumption has slowly came back to "normal" for my daily usage habits.
Currently running widgets: clock, profile, weather, next coming event, BBC feed, WiFi, 3G, data usage counter, Nokia Battery Monitor, locations near me. Also Nokia Sleeping Screen is active. I gave up in using email widgets because I only use IMAP manual fetch mode and in this mode they are completely useless.

MacBook Pro 15" Power consumption
What is the average power consumption of a MacBook Pro 15" please? I need to buy a battery backup to cater for power cuts.
Yes, you cannot partition the RAID, period, after creation.
The 2011 models and later have 6.0 Gb/s HDD interfaces with 3.0 Gb/s for the optical drive until after the 17" model, then 6.0 Gb/s on both interfaces. But no such support for the 2010 models like yours.
i honestly don't see the point of installing two large capacity SSDs for a RAID setup. I put smaller SSDs where the HDD was and a large HDD in place of the optical drive. I use the SSD for startup and the HDD for storage. -
[Solved] High power consumption of eth0
Hi everyone,
i successfully installed Arch on my new Acer Travelmate P653-MG a few months ago with the Gnome DE. Everything worked fine until a few weeks ago, when i discovered a really hard power regression due to my network interface. Before i had a solid 12 W of power consumption (without that much of finetuning), but afterwards my power consumption jumped to 23-25 W. I have attached two screenshots of my current powertop output:
http://i.imgur.com/8tpSnXf.png
http://i.imgur.com/CaVg61A.png
Unfortunately i can't quite say when this regression occured, so as to point to a certain update. My first guess was, this had to be kernel specific, but the downgrade from kernel 3.7 to 3.6 brought no results. I must admit after hours of searching google, the arch wiki and the forum here, i'm at a complete loss. I have discovered no one with a similar problem.
If anyone can help me in this matter, your help would be very much appreciated!
My current kernel parameters are: quiet splash nmi_watchdog=0 acpi_osi=linux acpi_backlight=vendor
Please tell me any outputs i can provide which could be of help to you.
Greetings

Last edited by ToshiroTaicho (2013-02-16 22:08:07)Thanks for your suggestions, but i was finally able to figure it out myself. linux-lts was unfortunately no option for me, as i want to use bumblebee. But the direction, this pointed me to was good. It seems one of the kernel updates broke my bumblebee package, so the power management didnt work and the card was constantly powered on. This was nothing new, but my powertop completely messed it up, by adding this additional power consumption to eth0. Funny enough, this power consumption even disappeared, when i unloaded eth0. After deleting powertops saved results and recalibrating it, it now shows up all components power usage correctly.
Thus i mark this thread as SOLVED. -

When will Verizon customers be able to download and use this new mode?
Thanks!I recently bought an HTC One m8 from Verizon, and like many other customers the Extreme Power-saving Feature was one of my keys factors to deciding to buy. I was very disappointed to learn after the fact that Verizon had not included, and has no intention to include the feature in the future. (Mentioned in other threads in the forum). I've read the argument made that Verizon never advertised the feature and never said it would be included with their version of the phone, but they also never went out of the way to warn perspective buyers that the feature, which is part of the m8 phone on other carriers and marketed by HTC as a part of their phone wouldn't be included. When people are researching phones before they decide what to get they read what features the manufacturer(s) have designed and implemented in those phones, not search to find all the things the carrier may have stripped from the phone.
It's impractical and offensive to tell a customer that its his/her responsibility every time they buy a phone from them to dig deep into website forums and look for what they decided to remove from it that the manufacturer had built, and advertised to be in their phone. This is the type of thing that is bad PR for Verizon, and something that will make customers go to other carriers. I don't want to offend some of the nice Verizon employees who want to help their customers and simply don't have the power to correct the issue themselves, but its in Verizon's best interest to either fix their network to work with this feature, or find/hire someone else who will. Doing it soon before the issue escalates and news of Verizon's statement to do nothing to correct the issue for their HTC One m8 customers spreads like wildfire and burns them.
I hope someone at Verizon doesn't let the rest of the company go on ignoring the issue and steps up to find a way to enable Extreme Power Saving Mode on the Verizon Network. Right now the impression many people have is something along the lines of: now that you've bought a phone from us, and signed up for a contract with us we don't care what you want and think.
In the meantime it would be a good idea to enable the option in the phone with a popup message when enabled that reads something along the lines of: Verizon has concluded that in some cases Extreme Power Saving Mode can cause network issues. If you experience network issues please disable extreme power saving mode and return to one of the other power modes. Verizon will continue to research the issue, and will institute a fix if/when a solution is found. -
Power consumption double compared to windows... where could energy be
I just bought a new Laptop (Acer Aspire 5755g), and first thing after I got it was, of course, installing arch ;-)
However, I noticed that the energy consumption under Linux is at least about 22 Watts in idle mode, while it uses only 10 Watts on the preinstalled Windows 7. I was wondering where the big power leak could be. That's what I already thought of:
• I enabled most of the laptop-mode energy saving options, that means ondemand CPU governor, soundcard/ethernet/wireless powersavings, usb autosuspend, hard drive power saving etc...
• Since it is a nvidia optimus laptop, it has two graphics cards. However, I disabled the nvidia graphics card in the BIOS (what saved about 5 Watts), and I think the remaining "cheap" intel chip should not use that much power.
• The laptop has an LCD LED display that can be quite bright. However, the 22 Watts are measured when background light is almost at the minimum.
Are there any ideas, where else the problem could be?
I know of the kernel power regression discussed on phoronix recently, but can this really double the power consumption?rggjan wrote:
I just brought it down to under 8 Watts! Using this trick:

What made the laptop finally turn of the fans, and really saves a lot of power...
Indeed, this and the pcie_aspm option, plus disabling the NVidia card with power management from Bumblebee (extra dangerous BTW, I would not recomend, though I use it) and unloading some modules, took my Alienware M11xR3 consumption down to 7.95W. -
Influence of the hold button on power consumption
Hi,
does the hold button reduce power consumption when turned on, even when you do not accidentally touch the clickwheel and activate the ipod? Is power consumption also reduced when you turn the hold button on after shutting the ipod down and putting it away? Or are these effects minor/non-existent?
I read the ipod also consumes power when it is turned off, is this caused by its internal hard disk?Like many electronic devices these days, iPods, PDAs, Cell phones, and even your computer, none of them are truly completely off anymore. As you might note, almost all devices these days have momentary push buttons to turn them "ON". In reality, there has to be some people to monitor these buttons and wake up the rest of the device when the power button is activated. So yes there is always some level of power being consumed by your iPod all the time since it has to keep monitoring the click wheel on the front to see if you are asking it to power up again.
As to power consumption, your two largest users of battery power are the hard drive spinning and the backlight being on. If neither of these are active, then the iPod is likely using very little power even when there is a display (with no backlight) and someone less when the display goes off completely (the iPod is asleep). The state of the hold switch is not likely to effect power usage one way or the other. Basically is it is nothing more than a state reported to the processor to ignore other key presses including power on. So like when you need to push the front wheel to get the iPod to turn on and the iPod is always monitoring those buttons to be pressed, it is also monitoring that hold switch to see if it should act on any of those buttons. So even when the hold switch is off, it is still being monitored regardless.
