KDE 4.6 more power hungry?

Hello there.
Just upgraded to the latest KDE release, which worked greate, only thing I noticed is that through Powertop KDE 4.6 seems more power hungry. It seems to draw around 3~4 watts more, does anyone else notice something along the same line?

In KDE4.5.* those percentages were less than 2%. Maybe this has a bearing on your observation?
Thats the strange part, my system is behaving like with 4.5, nothing is using excessive amounts of CPU or Mem.

Could you post how you did that? I have turned off Nepomuk, don't know about akonadi.

Getting rid of my power hungry pc tower

Hi there
i was wondering how the macbook pro 17" would compare to my trusty 3 year old desktop pc
(abit ic-7g, single core p4ht 3ghz, 2gb ram, radeon 9800 pro 128, iiyama 22" ma203dt crt)
one selling point for me is the maximum power consumption figures
82 watts for the macbook pro
450 watts (Max) for the pc
140 watts for the crt monitor
my first real question is graphics related, will i get the same, better, or worse performance out of the Mobility Radeon X1600 with 256MB compared to the radeon 9800 pro 128 pci. the only game i play is world of warcraft so if it runs this game as good or better that would be great to know.
second is heat related, i use my pc to watch dvb tv brodcasts and was thinking about getting the Elgato EyeTV Hybrid (DTT +Analog TV) with analog input , would i be better getting something else, something that takes more strain of the cpu to keep things cool for extended periods, four hours plus.
will leaving a macbook pro on for 4 or 5 hours a day send it to an early grave?
finaly, things have moved on since i made my pc, how much though, is it worth throwing my huge power hungry pc monstrocity out yet or, should i wait a few months and see what apple have up their sleeve
ibook G4 1.42 Mac OS X (10.4.7) abit ic-7g, p4ht 3ghz, 2gb ram, radeon 9800 pro 128, iiyama 22" ma203dt crt

Well i went ahead and got a new mbp and it does indeed outperform my clunky old desktop pc, it doesn't sound like a jet fighter taking off though, which is a bonus i guess ^^
i can run wow at 1680 x 1050 with every setting turned up to max, on my pc i was running the game at 1280 x 1024 with one or two settings turned down a tad.
as for the underclocked videocard, i found this somewhere on the net
http://barefeats.com/mbcd2.html
"...Though the CPU clock speed advantage of the 2.16GHz MacBook Pro is only 8%, it outperformed the 2.0GHz MacBook Pro by as much as 43%, depending on the application... we rechecked the 17" MacBook Pro's X1600 GPU's core and memory speeds before, during and after running 3D Games using Graphiccelerator's "Show ATI Frequencies" function. Before starting a series of runs, the core measured 311MHz frequency. When we ran 3D games, it jumped to 423MHz. After sitting idle a few minutes, it fell back to 311MHz. We measured a similar jump in the GPU's memory clock from 297MHz to 450MHz."
all i need to do now is find a good decent dvb device and im good to go i guess

Skype on E72 while on GSM of UTMS is power hungry

I have been using Skype on my E72 last 1 month and have noticed that it consumes about 200mA of current while running in the background with no communication in progress using GSM or UTMS. It consumes much lesser current when using WLAN. However Fring consumes very little curent in both GSM/UTMS and WLAN mode. Skype has to check on this and improve the power consumption issue.

Skype is a power hungry protocol. It's a P2P application essentially which is going to be fairly processor and/or network intensive.
If they'd used the open standard SIP protocol, there wouldn't be problems like this, and they'd be integrated fully into most mobile devices with no hassle and would work efficiently. But they went with their own proprietary protocol . Skype really needs dedicated hardware to work best.
As for Fring. Are you using it for Skype calls? Still Fring is probably just more optimised for the S60 platform, but still I'd bet for Skype calls it drains more power than a SIP call would via the native support.

Laptop-mode draws more power than no laptop-mode

Hey all,
I finally took the plunge and installed laptop-mode-tools. I edited the main configuration file to my liking and enabled those extra powersaving features I need. The other ones I have disabled. However, when I enable laptop-mode my battery is drained faster than without! I am pretty sure this is not what it should do
I'm clueless as for where to look though, because I didn't change any critical setting (AFAIK) and I didn't enable any 'extra' features: i just enabled those found in /etc/laptop-mode/conf.d that I need and disabled those that I don't need. Can you help me pin-point which feature of laptop-mode-tools draws more power out of my battery?
Here's the list of features I have enabled:
auto-hibernate.conf
dpms-standby.conf
ethernet.conf
intel-hda-powersave.conf
intel-sata-powermgmt.conf
lcd-brightness.conf
nmi-watchdog.conf
runtime-pm.conf
sched-mc-power-savings.conf
sched-smt-power-savings.conf
terminal-blanking.conf
usb-autosuspend.conf
wireless-power.conf
Those that I have disabled:
ac97-powersave.conf
battery-level-polling.conf
bluetooth.conf
configuration-file-control.conf
cpufreq.conf
eee-superhe.conf
exec-commands.conf
hal-polling.conf
start-stop-programs.conf
video-out.conf
wireless-ipw-power.conf
wireless-iwl-poweac97-powersave.conf
battery-level-polling.conf
bluetooth.conf
configuration-file-control.conf
cpufreq.conf
eee-superhe.conf
exec-commands.conf
hal-polling.conf
start-stop-programs.conf
video-out.conf
wireless-ipw-power.conf
wireless-iwl-power.confr.conf
Thanks in advance!
PS: if you need any files, please tell me. As I said I am clueless what could cause this, so I could give you a list of all the laptop-mode files I have edited but I don't think this would help anything.
EDIT: I have disabled the cpufreq one because I use cpupower and have that setup without any laptop-mode-tools interference. I use the on-demand governor all the time. An extra question: do I need those sched-{mc,smt} features in laptop-mode, if I have configured those in cpupower as well? For now I left them in, but I was gonna figure this one out still.

Finally had the time to do some testing with powertop. The highest result I get are these:
Top causes for wakeups:
35,8% (309,7) [Rescheduling interrupts] <kernel IPI>
28,8% (248,8) PS/2 toetsenbord/muis/touchpad interrupt
The first I have also without laptop-mode, the second I don't have. However, it does seem to drain a little slower now. Anyway, any hints to persue to get those wakeups down?
PS: powertop also suggested this:
Suggestion: Enable the CONFIG_INOTIFY kernel configuration option.
This option allows programs to wait for changes in files and directories
instead of having to poll for these change
Does the Arch kernel have that by default or do I have to build my own kernel for this?

Interface Apollo 16
Pro Tools is curretnly not compatible with Maverick. Also, I believe that Pro Tools 10 only allows 4GB ram to be utilized (not sure )
I know Pro Tools 11 allows more, but not sure how much more. Also not sure if the upgrade to Pro Tools 11 I will have to purchase all new plug ins or if my existing ones will continue to work in it.
The platform changes from 32 bit to 64 with the upgrade to 11
If it is as simple as adding more ram, what mode-part #l would you recomeend. Can the processor be upgraded also ?
The new tube like Macs are non compatible with UAD Cards. Those cards a must my sessions

You can use Activity Monitor to check if apps run as 32 or 64 bit - simply look at the "Kind" column (you may need to select it under View -> Columns) and see if the app in question is listed as "Intel" i.e. 32 bit or as "Intel (64 bit)".
While in Activity Monitor you can also check if Pro Tools is close to the 3-4 GB limit of a 32 bit app - if you aren't you will probably not benefit from more RAM.
Your MacPro (it appears to be a Early 2009 model) should have come with a small booklet showing how to install RAM and what kind of RAM that you need. Any RAM that fulfills the requirements should work but your safest choice is probably to buy from a retailer/online store that supports Macs as they will usually know what kind of RAM you need for your mac model.
Upgrading the CPUs should be possible, but I haven't seen Apple document how to do this, so you will probably have to google around a bit to find instructions and CPU part numbers.
Your choice of CPUs will also be limited by the motherboard and CPU socket so you may be limited to faster version of your current CPU chip and some slightly newer versions.
Going from your current CPU to the fastest version included in the 2009 MacPros would be going from 2.26 GHz to 2.93 GHz. This would only give a modest 30% speed boost. Using newer and highly clocked CPUs might boost this somewhat more maybe to 50% ?

Hi Since updating to ios 7.04 i have noticed the phone consumes so much more power. I have to charge the phone twice sometimes 3 times a day. WHY?

Hi Since updating to ios 7.04 i have noticed the phone consumes so much more power. I have to charge the phone twice sometimes 3 times a day. WHY?

Hi,
Thanks! I forgot to add, I have debonded and rebonded the bluetooth in car and phone and have carried out 3 restores on the phone in my ITunes. All to no avail. I have also jsut spent £40 on a lead from Ford that has made no difference too! I went to them today to request a software upgrade on my car as I though perhaps the lack of connectivity in the car was down to the car being behind the iOS5 software but was informed there was no need for an upgrade and this problem is purely an apple problem! Is there any way around the downgrade? Or are apple gong to resolve this problem at all??

Faces Has More Power in Aperture vs. iPhoto

I came across this on Apple's site for Aperture:
The popular Faces feature in iPhoto comes to Aperture 3, where it has even more power.
What added power does Aperture bring that iPhoto does not?

Well ... does the Apple site say anything?
Aperture takes Faces further.
Aperture 3 expands on the power of Faces in iPhoto. Not only can you view the people you name across the entire library, you can now see them in individual projects. And the new Show Unnamed Faces pane displays all the detected-but-not-yet-named faces in a project to help you easily add names
I don't use iPhoto, so I can't comment on whether this has changed in the interim for iPhoto.

When I plug in a Lexar thumb drive, I get a "USB Low Power Notice' saying it cannot operate because it needs more power than is available. This is new. Thumb drives worked last week. Any suggestions? Is this an apple or a Lexar issue?

Apple intentional, use a powered USB hub instead.

Why my ipad (4th Gen) consume more power when reading books in ibook than surfing over wifi

when i m reading my books in ibook it consume more power .I notice that power decrease 1% per 4 minutes

Power consumption increases significantly when the screen is set to a high brightness. If you are using your iPad ins a bight environment, for example, outside, flourescent lights, etc. and have auto-brightness turned ON then the iPad will automatically increase screen brightness resulting in higher power consumption.
Also using small changes in battery percentage to predict total power reserve is not very accurate.

More power with a USB 3.0 cable?

I have an external drive that uses a y-cable to get enough power to operate. Would a USB 3.0 cable deliver more power to my external hard drive so I don't have to use the y-cable?

No. The power is determined by the port, not the cable. Besides, there is no USB 3.0 hardware in the MBA.

My ipod touch don´t have much sound on musics (i already go to settings- music-sound limit unlock), i need more power sound for using ipod to teach fitness classes what can i do!?

My ipod touch don´t have much sound on music tracks (i already go to settings-music-sound limit unlock), i really need more power sound for using ipod to teach fitness classes what can i do!?

I imagine that... a limit of sound because ears problems understand that...but in my case i need power i´m not buying a better surround for the gym (the owner must do, but everyone use cd´s and i not see me record cd´s again) ...its the only problem for this iPod to be perfect.... I´m in Portugal, by the way!!! and thanks again for you helping!!

Does scheduled startup shutdown use more power

Hello. I have a computer that the power supply is starting to go out on. I've seen it multiple times and it's in it's early stages. My question is does using the scheduled startup and shutdown require more power and should I turn it off? Thanks.

Check all of your settings and make sure you have optimized them all, sometimes when you do an upgrade it changes your settings. ie, notifications, location services, date and time auto, etc.

Adjusting the vcore voltage to get more power

wat wud be a safe voltage 4 me to rise it 2 at the moment its at 1.64v wat wud be the highest i cud go wit out burning out the cpu

lmao voltage is power to the cpu raise it is force fed more their for it can go to a higher clock speed. peewee2004 check your temps i thk some go up to 1.8 aslong as the temps stay under control.
GO ahead and lyao, he asked about raising vcore for more power. not raising vcore to clock higher for more power. I should have posted: Raising Vcore alone does not give you more power. My bad.

6131 is power hungry, bad design?

I am disappointed by the battery of the 6131. It is worse than I could ever imagine when I read the reviews mentioning the "battery" problem.
It can't even last 12 hours. I don't spend the day talking...I check my mail a couple of time a day, talk a little, less than 30 minutes per day. It even drains overnight when the phone is off. What is wrong with this phone?
Any suggestion on how to reduce the consumption? Also, does anyone know if there is a design problem for that phone? Some kind of power leak? Anyone had their phone replaced?
The phone is great, the battery is horrible.

9600M GT: 5W more power-draw after wake up from sleep?!

Hey Ladies!
I measured the wattage of my Macbook Pro with both the 9400M and 9600M and found that the 9600M GT draws 5W more power after wake up from sleep than before sending the MBP to sleep.
Looks like a bug to me?!
