Running the laptop in "battery optimized cooling method" - harmful?

Hello,
I have been getting very irritated by the amount of noise emitted by the fan whenever my laptop was plugged to the electricity, even while performing very simple tasks such as Internet browsing or word processing.
I have therefore switched the cooling method under Vista's Advanced Power Options from "maximum performance" to "battery optimized". Now the computer is pleasantly silent but I was wondering whether it might damage the laptop in any way when I run it in this mode despite being plugged to the AC. Should I perhaps also reduce the "maximum processor state", which is currently at 100%?
Best regards,
Martin

Hello Martin
Believe me I use absolutely the same settings almost half year now. And I am satisfied. The notebook runs well and cooling fan is silent.
The question is for which operations you need your notebook. If you use it for every day operations like writing mails, checking different stuff in Internet, downloading music you do not need high performance level. I recommend you to use balanced power plan in power options. Only set the display brightness to higher level and you can continue to work.
Using the same power settings I have good working and absolutely silent notebook.
One other thing: before notebook comes to the market it must be properly tested and I really do not believe Toshiba will offer some settings that can damage notebook hardware.
Simply choose your favorite settings and be happy. ;)

X201: running the longest on battery

Hi all,
Any recommendations on how to run longest on battery. I know about battery stretch and function on optimized power. But are there any other tricks?
Thanks!
moderator note: model added to subject line
x201....3249-CTO....i7....4GB RAM....64-bit OS....Windows 7

Switch your wireless card off if your not using it with the switch
Use the laptops native resolution try not to use graphic intense applications eg watching a movie playing games
Don't have external devices attached eg USB's external DVD drives
Use standby everytime you stop using your computer by pressing Function F4
Shut down any background applications you don't need after a restart they will all come back up again anyway
Keep your laptop in the coolest temperature you can eg don't sit iyour laptop n the hot sun
Clean your battery terminals
If you really were serious about battery life you could consider replacing your screen with a LED back light version. Some models have versions that have that option. Most people however might find this to be over the top myself included but it might be an option to think about when you buy your next laptop.
Hope this list is of some help

Does it harm the battery if we use the laptop while charging?

If we use while charging, is the power required directly taken from the external supply or from the battery itself. Which is the safest way to use the laptop without drawing power from the battery?

No harm is done. There is enough power from the adapter to run the laptop and charge the battery. There is hardware and software in place which prevents any problems. The laptop will not take power from the battery while the AC adapter is plugged in.

HOW TO MAXIMIZE YOUR LAPTOP'S BATTERY LIFE

Hi all,
I had this bad experience of this wide problem in laptops, battery failure. It happens almost just after your warranty expires many will agree, funny & true..battery stops charging, shows less than 100% or 0% charge no matter how you try to charge it..etc. Also many complain that the battery shows only remaining charge time, and not the time remaining (read 9th tip below).
Though Mark, Andy, vkyr, nonny, jhem, bill, myles and other admin guys are here to help on this forum, I thought of writing this based on my own experience of these batteries till date..I had compiled a few tips and information for dummies about the use of battery here which might help you to extend battery life:
NOTE to moderatos--please check / modify / add / edit in the following if you find any wrong information.
NOTE to all -- These tips in no way will harm your system, except the 9th tip and also if you remove battery without shutting down laptop
All are welcome to add any new tips or corrections.
1. Never discharge battery to 0%. Always, ALWAYS let battery discharge to a lower limit of up to about 5 to 10%.
2. To run it or not on AC supply without battery If you use laptop most of the time at home or a place where there is a continuous (= uninterrupted) power supply, then simply remove battery from laptop and run laptop on AC power. If you are doubtful about current surge in AC supply, use a surge protector or a UPS (uninterrupted power supply) unit, which doesn't cost much. But be prepared, sometimes you may lose the data which is not saved, due to any accidental interruption. As [Bill] pointed out there might be a performance degradation due to power failure.This is not recommended if you are unsure of power supply.
3. If you use AC power most of the time, then store battery with 30 to 50% (about 40% optimum) charged condition in a dry, away from any magnetism. At least once in a week or two weeks, run the laptop on only battery supply, let discharge it to about 10%, connect to AC supply, charge battery to 100%. Shut down, disconnect supply, remove battery from laptop and then use AC power supply as usual again.
4. If you are running out of remaining battery time, then instead of shutting down PC, hibernate it ( you need to enable hibernation before through power settings in control panel). Shutting down takes more time than hibernation and without saving anything, you can resume your work after hibernation. After hibernating, even if you remove battery, it won't lose any data and will resume once you connect laptop to a power supply.
5. Use power schemes (power management profiles), modify options available in power options under control panel in windows according to your usage & habits. Instead of using a blank screensaver or a screensaver which looks cool, turn OFF monitor, use lenovo power management options or windows power schemes to do this.[Tom&Wjli2]
6. When running on batteries, to save power - reduce brightness of screen (using keys Fn + F10 to reduce, Fn + F11 to increase), mute volume & turn off any unnecessary devices that you are not going to use like (thanks to [Nicolas])bluetooth / modem / plug&play monitor / network adapters(wireless/ethernet/lan/1394) / PCMCIA adapter. Use 'control panel->system->hardware->device manager' to turn these devices on and off.
Changing color schemes to dark or black colors doesn't save power in case of LCDs. (http://savingenergy.wordpress.com/2006/11/21/saving-energy-one-monitor-at-a-time/)
7. Whatever you try, a battery has a specific life time (no. of charging/discharging cycles), and it discharges slightly/continuously over a long period even when not in use. So if your battery is giving problems after about 3 years of service, then it is time for its replacement. Don't assume that if you don't use battery more often, it will last longer, it may usually, but battery failures are unpredictable.
8. If your battery has started to show problems, it will most likely fail sooner or later. Consult experts if battery is under warranty, else buy a new one.
9. Either use lenovo's default program or you might try a program like Notebook Hardware Control (http://www.pbus-167.com/ ) to monitor your power & hardware / temperature. This program shows remaining battery time once you modify advanced options for battery. Also it shows various temperatures for CPU/HDD and warns you if temperature reaches preset limit.
Caution: though this program allows, don't try to modify voltage settings under advanced options, it can harm to your system.
Added:
10. Never run a hot laptop or a hot battery. It damages the battery/laptop, so be sure to keep temperatures within normal range.(below 140 F or 60 deg C).
11. There are few more good/advanced points added by Tom on Page 2.

Dear iamdh,
Thanks for your answer and your update of the main post. I also read the various interesting articles you mentioned.
Now, I would like to submit to you these interesting questions :
Question 1 : Please do the following test : Open Paint, enlarge to full screen, set image size at least the size of your LCD (e.g. 1500 x 1200 dots) and use bucket tool to fill the whole image in pure black. Now, go to control panel, display, screensaver tab, and select Blank screensaver and test it with the View button. DO YOU SEE A DIFFERENCE between the black screen in Paint and the blank screen of screensaver ?
I don't see any difference (I use a vaio A517S laptop with high brightness LCD), so the conclusion might be that the blank screensaver uses up the same energy than a black color screen. A 2nd experiment leads to the same conclusion more conclusively : View again the "blank" screen (in screensaver tab, View button) and play with the Fn Keys to change brighness. You will notice that that it is impacted by brightness level which means the blankscreen is NOT a real "blank". WHY IS IT IMPORTANT ? Because, if choosing the Blank screensaver uses up the same energy as a black screen, AND because the black screen doesn't make any difference with a white screen on a LCD (remember the paper you found), then, why choose the Blank screensaver !!? Or, is it the fact that colors don't make any difference with LCD which is wrong !?? At that stage, I only ask. It is logic, it is one or the other, isn't it ? Any comments welcome.
Question 2 : You remember that energy transforms into various forms : light, temperature, strength, movement, etc... Now, let's come back to LCD monitor : IF a black full screen and a white full screen uses up the same energy (youy remember the paper http://savingenergy.wordpress.com/2006/11/21/saving-energy-one-monitor-at-a-time/), then, there is a interesting point : Because the white screen gives more light than the black (you can check that in the middle of the night using your laptop as a spotlight torche !), it means that the black uses up its energy into an other form. ...What could it be, other than temperature ? LET'S PUT IT AGAIN DIFFERENTLY : The black screen and the white screen use up the same energy, but why it is used for brighter light with the white, it is used for higher temperature with the dark. WHY IS IT IMPORTANT ? Because higher laptop temperatures damage batteries quicker, then it means that we should avoid dark colors and prefer light colors in our windows settings. .. any comment welcome
Really, the central point of discussion is the fact that electricity LCD consumption is not impacted by colors, even white or black. Has it been really double checked by many ? A story to follow..

USB mouse disconnects when laptop on battery

Hello,
I am using Gnome 3.6 on 3.6.10-1-ARCH. Whenever I run my laptop on battery power, my external usb mouse disconnects after some inactivity period. If I plug it to external power source, it again starts working fine.
I suspect there must something in gnome 3.6 (weird optimization) or something to do with laptop-tools which disconnects the usb mouse after some time of inactivity to save power. How to fix this.
I referred this link, but it did not provide me way to fix this.
https://bbs.archlinux.org/viewtopic.php?id=49503
https://bbs.archlinux.org/viewtopic.php?id=149530
Update: I noticed that I had not enabled laptop mode tools so problem must be with gnome3. I have now enabled this and set my USB mouse id in blacklist, so that it does not autosuspend. Still It is getting auto suspend.

I imagine that your usb ports control is set to auto... which will suspend the device after a time of inactivity. The solution would be to have this not set to auto... though I am not sure how to do this with laptop-mode-tools in place. I don't use laptop-mode-tools, and it is my opinion that it actually makes things harder when you encounter things like this. Instead of learning where the configuration for this is within /sys and then creating the necessary configuration to change it, you now learn where it is in /sys, what is changing it automagically for you, then you have to learn the intricacies of that particualr power management tool.
So although I cannot help you with yout laptop-mode-tools, the file that sets this is /sys/bus/usb/devices/usb[1-9]/power/control or /sys/devices/pci0000:00/0000:00:1a.0/usb1/power without the symlinks on my machine for usb1.
Just my opinion, but with the power that comes in computers these days (for the past several years in fact), having something like laptop-mode-tools is pretty worthless. If you just have all the settings set as though it were on "battery" all the time, I bet there would be no discernible difference. I know I cannot tell, and then my computer probably charges ever so slightly faster because it is not set to consume more power when I plug it in.

Reformat a HP Pavilion g4 and reinstall windows 7 using product key at the back of the laptop

I would appreciate it if I someone can provide the instructions or point to where I can find them. Also, how do I reinstall the other necessary softwares and drivers to properly run the laptop.
Thanks.

Hi,
You can do this as follows.
Create an installation disc yourself using another PC - just download the correct Disc Image ( this must be the same version - ie Home Premium, Professional, Ultimate etc - that originally came with your notebook ) from the link below and use an application such as ImgBurn to burn the ISO correctly to a blank DVD - a guide on using ImgBurn to write an ISO to a disc is Here. These Images are clean and from a well-respected source - Digital River.
Windows 7 Images.
Use the disc to perform the installation, enter the Windows activation key found on the COA Label when requested and when the installation has completed, use the 'Phone Method' detailed in the link below to activate the OS - this method supported by Microsoft and is popular with people who just want a clean installation of Windows 7 without the additional software load normally bundled with OEM installations.
http://www.kodyaz.com/articles/how-to-activate-windows-7-by-phone.aspx
Any additional drivers and software you may need can be found starting by entering either the full Model No. or Product No. of your g4 series notebook Here.

How do i reset fans on a macbook7,1 running Lion? I've tried the non-take out battery reset smc method and i've done the cmd-alt-P-R resetting of something. Still when everything in loaded it sets the fans really high and then goes down to normal in..

... seonds and it won't use fans as it usually does. This all happened because i did a clean install while having fans at 3100. Please help me reset my fans!!!

OK....you were using SMCfancontrol?....and you reinstalled the app after the clean install?......did you open Preferences for SMCfancontrol and run the slider that controls the fan speed back to the left? (Apple default speed)......my 4,1 MacBook is about 1800 rpm...

My battery needs service as it is not working for long. Apple claims it is not a defective battery and that it is my fault since I had the computer for 2 1/2 years and have only run the battery down to empty 100 times. It is my fault because I did no

Con't
Apple claims that because I did not drain my battery frequently and kept it plugged in for extended periods of time, that it is my fault the battery is failing. I disagree because I was not ever told to consistently drain my battery before recharging or not to keep it on and plugs in for extended periods of time. I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods. I feel that Applecare should cover this battey issue and not charge me for replacing the battey. I feel I should have been told to not keep my computer consistently running on with poweror the battery will fail. Has anyone had this problem? Apple should replace my battery under Apple care as my battery does not keep a charge anymore.
I'll wait to hear.

You said---Apple claims that because I did not drain my battery frequently
You said--- I was not ever told to consistently drain my battery before recharging
You should never do that on purpose, whoever told you that had it wrong or you misunderstood something
Sure you dont have that backwards? thats exactly what you DONT want to do.
Did you often drain the battery very low? that would explain a lot.
Someone might have been misinformed about "battery calibration" regarding much older Macs with removable batteries (see bottom)
You said-----I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods.
thats a problem there, youre not supposed to do that.
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
*If you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
And best "tip" is if its near a socket,...plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of the time.
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace
Battery calibration, battery memory, battery overcharging, battery training, …all these concepts are mostly holdovers from much older battery technology, and on older Apple portable Macbooks ranging from early nicads, NiMh and otherwise; and these practices do not apply to your lithium battery and its smart controllers.
Calibrating the battery on older Apple portable Macbooks with removable batteries.
http://support.apple.com/kb/PH14087
There is no calibration of current Apple portable Macbooks with built-in batteries.
http://support.apple.com/ht1490
There is no battery calibration with current Apple portable Macbooks with built-in batteries. Lithium batteries have essentially a 0-‘memory’, and all such calibration involve the estimations fed to the system controller on the SOC (state of charge) of the battery over long periods of time as the battery degrades. The software based battery controller knows the battery's characteristics, or SOC and adjusts itself. This is why there is both no need and purpose to periodically deeply drain your macbook battery, since it doesn’t affect the characteristics of the battery, and further still deep discharges are something you should not do on purpose to any lithium battery.

No license when the laptop is in battery operation

Hello
I have got a problem with the new license since LabVIEW 8.0. I activated the license when the laptop was in mains operation. When I try to start LabVIEW when the laptop is in battery operation, there is an error because of changed hardware. When I put in the power cord and restart LabVIEW, LabVIEW starts normally. Does anybody else know this problem? How can i start LabVIEW when there is no power outlet?
My laptop is from HP, the model Compaq nc8430. The processor is an Intel Centrino Duo.

Hello
The reason you are receiving this message is that the computer ID used to
generate an activation code for LabVIEW is based, in part, on your ethernet
card's MAC address. It sounds like when you change to battery mode that Windows
is reporting a different MAC address to the license manager.
I can generate a computer ID for you based on your hard drive's disk volume
serial number which you could use to activate LabVIEW again. This would prevent
this issue happening again in the future (well at least until you changed your
hard drive but I guess you'd be reinstalling LabVIEW at that point anyway).
In order to get that computer ID to you I need to know what your Volume Serial
Number is, this is how to get that:
1. Open a command prompt. Go to Start»Run
2. Type "cmd" (without the quotes) and click OK
3. At the command prompt, type "C:" (without the quotes) to change
the active directory to your C: drive
4. Type "vol" (without the quotes) to get your Volume Serial Number.
Once I get that from you with your Labview Development System (Base, Full,
Professional). I will reply with a computer ID number you can use to activate
LabVIEW at http://ni.com/activate/

TS3276 hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
One of the whys could be a magnet that is making the computer think the lid has been opened.

Can not start X when the laptop boots from battery

Hi,
I have just found out recently that X doesn't start when i boot my laptop from battery. After the daemons are run, X is started and then shows me a blank black screen. Ctrl-Alt-Del or Ctrl-Alt-Backspace don't work. And i can't change tty like Ctrl-Alt-F1 to escape to the console. It just hangs.
When power cable is plugged then the laptop works just fine. Even if i pull the cable out afterwards, it continues working on battery mode.
What can be the reason ? Has anyone the same problem ?

Hello,
the simple answer is no.
The Lenovo powermanager should do the work for you.
May be you are able to switch charging to automatic charging in powermanager settings.
I don´t know if the option, in the newest versions of powermanager, is choosen as standard.
May be there isn´t a switch or checkbox, cause the manager is doing it already.
But it won´t harm your battery, when you let it plugged in AC.
