Kernel patch for battery life

Using powertop I found out that the kernel was preventing my laptop from going idle and reading this page found out about a patch for it.
http://www.lesswatts.org/projects/powertop/known.php
However, that patch is out of date as I just got 2.6.24.3 today. Is there a recent patch for this as it is very annoying to only get three hours where I get five in vista.

Simple - the patching failed. Apparently you have patches that are conflicting here, and one file in concern is $startdir/src/linux-2.6.24*/sound/usb/usx2y/usx2yhwdeppcm.c but I can't tell what other files are involved since you didn't paste the relevant lines before this.
This is the PKGBUILD: http://pastebin.com/m6426d31a
These are the relevant lines before the error: http://pastebin.com/m10c1e6ff

Now that I know what broken-out means I notice that I could only choose to apply something in particular and not the whole patch, but I'm totally a newbie in kernel patching...

Last kernel patch for Solaris 10 x86 screwed up my kernel

Hi,
The last kernel patch for Solaris 10 x86 (sorry I can�t remember the patch id, but the revision is 30), available from Sun Update Manager screwed up my system.
The system is still booting but in maintenance mode: smf can't start because of repository corrupted. Given instructions to restore the repository does not work because / filesystem is mounted read-only...
As I am not a solaris expert, I will reinstall it from CD. I hope I won't loose the filesystem.
I was used to blindly trust Sun solaris patches, that was a mistake.
Laurent.

i dont know why but still i do get default log in into the single mode
after startup

N95 vs N93i vs N80i for battery life

Hi, I am buying a new phone and I really like the N80i [N80 Internet Edition] but I hear that it doesn't have very good battery life (less than 1 day). So I am also looking at the N93i and the N95. I know that they provide more features too over the N80i but I'm not so interested in those, I just want to know about the battery life. How do these three compare for battery life? (I know that the N93 standard edition seems to have better battery life than the N93i, but I can't seem to find anywhere to buy this one in my country).

Hi,
If you're not after with the features....why don't get Series 40 phones like 6233, 6280 and 6288? Which has a good battery life and much responsive compared to symbian phones.
We've tested the N6233..and it manage to hold its charge for almost 3 days with heavy usage.
Ouch! Only series 40 phones are symbian? S60 series phones(like the N series) are not, are you misqouted?
Knowledge not shared is knowledge wasted!

Best 7200RPM HDD for battery life

Anyone have any suggestions on the best 7200RPM hard drive for battery life? I think the one I have is draining the battery because it's the only thing I have changed. Even on 99% my battery indicator has never showed 7 hours, max I have ever seen is 5 so I assume its the hdd pulling the charge.

If you've only had this MBP for two days, have you even run the battery all the way down to see how long the battery actually lasts? What you see in the menu bar is only an estimate based on what you're doing with the computer at the time. It becomes somewhat more accurate over time (because it remembers your common use patterns) but it's never as meaningful as it seems. But if you haven't calibrated your battery yet, and you don't have enough experience with the machine to know how long your battery lasts in real life, you have nothing to be concerned about.

Which model (old or new) is good for battery life ...

hi. i want to buy old hp or maybe new model but don't know which is best for me. hope u can suggest to me which phone is good for battery life and signal receiver. thanks

Hi wadud
Ironically the simpler the phone the more likely that battery lasts for ages and has less bulk to screen the signal. I have a 1100 for emergencies which holds it's charge for months admittedly switched off, whereas N82 Smartphone won't last the day in use without charge.
Happy to have helped forum in a small way with a Support Ratio = 37.0

ABAP and Kernel Patches for Upgrade and Conversion in 4.6C

Hi,
We are in a process of upgrade and unicode conversion for the source release 4.6C (Kernel 46D_EXT Patch 2225).
"Combined Upgrade&Unicode Conversion Guide" for "SAP Basis 4.6C u2192 SAP NetWeaver 7.0 application Server ABAP Unicode Including Enhancement Package 1 Support Package 01 - 06" , In Software Requirements step, it says
"3. Import 4.6D Kernel patch 2326 from SAP Service Marketplace according to SAP Note 19466"
We wanted to know whether "IT IS ABSOLUTELY NECCESSARY TO GO FOR THE KERNEL PATCH 2326". We dont have "EBCIDIC code pages" in our MDMP system.
We need to know becauase we are also doing OS migration from AIX to Sun and this step will add to our production downtime.
Please advice what are the other causes we should go for the kernel 2326.
Regards

Hello Mr. Nils Buerckel,
Thanks for the reply.
We wanted to be very sure whether we should used Kernel 46D Kernel patch 2326 (As it is specifically mentioned in the SAP CU&UC guide and in SAP Note 867193, It is mentioned that "This patch contains enhancements that are required to execute the "INDX Analysis" scan)
OR
Can we go for the latest kernel patch avaialable at market place? And Will the latest kernel patch also contains the "enhancements that are required to execute the "INDX Analysis" ?
Please reply
Thanks

For battery life is it better to run my newly acquired 2010 Macbook Pro on battery most of the time down fully then charge or plug it in most of the time?

Just wondering about my 2010 Macbook Pro 13'
For the best overall battery life is it better to run battery down each time then plug in til fully charged or just plug in and use most of the time?
Thanks
Calpatrick111

Hi C,
Run it about 30 minutes a day on batt, the rest on the power adapter. Every month or two, run the batt all the way down until it goes into forced sleep, wait five hours, then charge it all the way up.

Kernel patch for more CPU families offers measurable speed increases

I wanted to show folks a pretty nice patch that allows one more options when compiling a kernel for CPU families. Complete list included at the bottom of this post. I tested it using three different x86_64 machines running a generic x86-64 kernel and an otherwise identical kernel running with the optimized gcc options.
Conclusion: There are small but real speed increases using a make endpoint to building with this patch.
Details:
1) Three test machines: Intel Xeon X3360, Intel i7-2620M, Intel Core i7-3660K.
2) All ran the make benchmark (linked below) 35 times while booted into a 'generic' kernel. Then all ran the same make benchmark 35 times after booting into an optimized kernel. Below are the optimizations chosen for each machine.
2a) X3360 = core2
2b) i7-2620M = corei7-avx
2c) i7-3660K = core-avx-i
3) Analyzed resulting distributions for statistical significance via ANOVA plots that clearly show statistically significant albeit small differences.
Discussion
1) All the assumptions for ANOVA are met:
*Data are normally distributed as show in the normal quantile plots.
*The population variances are fairly equal (Levene and Barlett tests).
2) The ANOVA plots clearly show significance.
*Pair-wise analysis by Tukey-Kramer shows significance at the 0.05 level for all CPUs compared.
Below are the differences in median values:
core2 +87.5 ms
corei7-avx +79.7 ms
core-avx-i +257.2 ms

I agree, your CPU, in practice, is really either idle or loaded.
In my case (AMD 965, 4 freq steps) the processor is at lowest freq for about 90 - 95% of a time, and at highest for 5 - 10%. The 2 intermediate are used for about 0.1% of a time.
My guess would be that intermediate ones are only used for smooth transition from lowest to highest. So they really are hardware dependent...

N80 Working ok except for battery life

Hi All
Just a quick one to say I have not had any of the problems everyone else is complaining about. The software version is 3.0617.0.3 and I am on Orange. My only problem is battery life, lasts a day! so I am about to turn off Bluetooth and the search for WLAN to see if this makes a difference. Orange said if not they would test the phone to see if it was faulty or the battery.
Oh one other thing the N80 does not like the Parrot CK3100 car kit.

sister_bliss, I have been following this thread with some interest as battery life is the biggest problem I have with this phone, I can live with or work around other issues until they are sorted via firmware. For information, with regards to how many features are running and signal strength etc, I use my phone on GSM only, bluetooth/infrared only when required - I have these set up as standby icons for convenience. Signal strength is excellent even on 3g and I have disabled packet data connection and use it only as required and I get a maximum of 2 days out of a full charge. Btw, I noticed yesterday that using the camera eats battery life, I sometimes need to take photos as part of my work - for reports etc, not often but sometimes and even shots taken in daylight use a lot of energy. Once again, if an application built into the phone uses so much energy it should be taken into account when fitting the battery, I buy a mobile phone to use as a tool not just to sit on my desk looking flash and tools get used - in my case frequently. Sorry if this sounds like a rant but nothing, imo, could be simpler to rectify than this, your thoughts would be interesting.

App for Battery Life

Does anybody know if there is an app to see how much battery life you have left? If not could someone design one?

SDK = Software Development Kit. It is what developers download to give them the development enviroment to code Applications for the iPhone. It has restrictions on what you can and cannot do. In general, any app written cannot interact with any other application or settings. Each app is self contained and that is the rule. However there are some services on the phone that Apple exposes such as allowing an App to tap into photo library/camera, read your location, keyboard, read contacts. But that is it. Thus no app can tap into other settings or alter the way another program works.

S260 & the best choice for battery life

hi,
with a s260, what's the best choice for the microprocessor for having the best battery life?
is there tips for increasing the battery life ? (software tuning, adding battery...)

Best settings for battery Life?

And away they go! Has anyone experimented with settings for optimal battery life?

Well, you have to decide what you want to use and when. To get the best battery life, you'd turn off everything (phone, WiFi, GPS, Bluetooth), and turn the screen down to the lowest setting. But that eliminates most uses of the phone (calls, email, web, location functions, handsfree).
I've been leaving 3G and BT on, turning off WiFi and GPS until I need them. Searching for WiFi networks can drain power quite a bit (judging from my experience with the 1st gen iPhone), and it seems to me that the location services were sucking power even when I wasn't using them. I haven't confirmed this last theory yet, but my battery does seem to last longer with it off.
I suppose a somewhat less-extreme approach than shutting off everything would be to leave on the phone, but disable 3G (and everything else). This would give you phone calls and (slow) network access, but no location services or handsfree devices. To me, this seems silly - it effectively downgrades your phone to a 1st gen iPhone, unless you don't mind flipping 3G on and off as you need it.

Kernel patch for Unix (Solaris)

Hello!
I have to patch, after successful installation, the SAP Solution Manager.
I know this operation is automatically can be executed with JSPM.
But in order to replace disp-work, R3Trans and TP I have to do this manually.
For this issue I have to stop all relevant processes, e.g. SAPOSCOL, DB-relevant-processes (Oracle)
In Windows area I would just stop all the processes.
<b>How this can be done in Unix area, should the processes be killed?</b>
Thank you very much!
regards
Thom

Hi
You can patch java components and kernel using JSPAM. But ABAP part can only be done using SPAM. To start you have to stop SAP ( bot JAVA and ABAP ) ,
stop SAP will take care of this , it should stop database and SAPOSCOL by itself.If saposcol didnt stop , use command
saposcol -k to stop the saposcollector. If it didnt stop you can kill it ( last option ) by
kill -9 <process id >
stop sap will stop database and its related process.If tns listner is still running , stop it by using
lsnrctl stop
Thanks

Arch Linux Kernel patch for kernels built from source?

I buitl I kernel from source because the hotplug thing was taking for ever
I really liked the arch logo. Is there a patch or is it possilbe to add the arch logo to the kernel?
Thanks

check out the PKGBUILD for the kernel:
run "abs"
and then go to /var/abs and edit the PKGBUILD for kernel26 to see how a kernel is built in arch
