Boot Camp depleted my battery life

Hi,
I installed windows 7 from boot camp and it significantly reduced my battery life from 9 hrs to 2 hrs.
I uninstalled windows 7 (remove partition) but I have the same battery life.
Is there a way to revert my battery life (fix this issue)?
Will reinstalling OSX (10.6.4) fix the issue?
Please let me know.
Thank you in advance.
Regards,

You can try calibrating your MacBook Pro's battery. Follow the steps in this article - http://support.apple.com/kb/ht1490
If that does not work, you should take your MacBook Pro to an Apple Authorized Service Provider or Retail Store, and get it serviced.

Boot Camp, Vista, and Half-Life 2 Episode 2

I am trying to run Episode 2 on my Mac Pro. When I first tried to launch the program it told me I needed to update the Nvidia 7300 graphics driver, or I could continue with the old driver. I'm thinking now I should have at least tried it with my original driver, but I upgraded from the Nvidia site. When I run HL2 at anything near high resolution (I have the 30 inch cinema display) the frame rate makes it absolutely unplayable. When I run it in a 640x800 window it's great but pretty small. Any ideas about how to increase graphic performance?

Hi and welcome to Discussions,
the 7300GT is in no way a gemers-graphic card.
And although HL2 isn't that much hardware-hungry, playing it in a 2560x1600 resolution (native on a 30" CD) is way too much for the card.
But HL2 should allow you to play in better resolutions then 800x600.
I think something like maybe 1280x1024 should be possible.
Only real solution for full resolution might be getting a ATI X1900XT

MacBook Pro Boot Camp Battery Issue

Hi all, I have just installed Vista on my MacBook Pro late 2008 via BootCamp. The thing is that I have very low battery life under Vista (1hr 50mins at 100% battery). Other than that, when I choose "Restart in Mac OS X" in the Boot Camp Utility on Vista, on Mac OS X I have no more than 4 hours battery life. When I shut down and start the MBP with Mac OS X again I now have 5 hours 20 mins battery life marked. I think this is a firmware issue, some hardware resources are not released by Vista or something of the sort? Am I the only one with this problem?

Since Windows uses the 9600M GT the power-draw (wattage) on the battery is alot higher. But even when both OS X and Windows use the same graphic OS X draws less minimum wattage.
XP is a special problem, because the NVidia drivers seem to have a bug that keeps them from clocking down the graphic-card in 2D and make the GPU run at full speed all the time. This does not happen on Vista though.

Windows 7 Boot Camp (Battery Issue)

I've noticed that my MacBook Pro 17" (10.6.7 - Early 2011) it's losing battery under heavy use on my graphic card, even plugged in.
With 100% of battery, after 1 or 2 hours of heavy processing, even plugged on energy, I get about 90% of the battery.
This happens only with Windows 7 on Boot Camp. Mac OS X has no issue regarding battery.
Is this supposed to happen?

That sounds normal. Macs running windows tend to have shorter battery life because windows is not set up to use energy savings like OS X is. You can adjust the settings in control panel but I'm not sure how beneficial that would be. I also heard that Macbook Pros graphic switching capabilities are not usable in windows as the drivers are not done for it.

It's not my imagination. iOS 6 is depleting battery life at a much faster rate

I own a black 32GB iPhone 4S. Being a fairly new apple customer ( my first smart phone 4s in feb 2012) I can't say enough about how great I feel apples products are. Top quality all the way and worthy of a higher price than any so called competitors devices. My only complaint is the addiction level that comes with these great devices. My phone is in mint condition having never left its case except for cleaning. However after updating to iOS6 my battery life is depleting much faster. Auto brightness is off with setting at half. Location services are off. Everything and all settings are set the same as always to minimize unessesary activity. Yesterday after unplugging my phone at 7am by 4:00pm it was at 1%. The last 20% was intentional to give it another complete charge which I do once a month for battery maintenance. Usage was just like any average day and I usually plug my phone in at night with anywhere between 20-56% left. This morning I unplugged it at 6am and by 8am it lost 3% with no usage. Not sure why but I'm OCD on all my electronic devices ( studio equipment included) so I am hyper aware of there operating condition. So this happening why? I have noticed a significant improvement in web page load times as well. Is this increased speed drain faster? Just a long winded observation. Hope an update can fix this.

Hotspot functionality is entirely dependent upon the carrier.
Do they support Hotspot?
Is the account properly provisioned for the feature?

My iPhone 3Gs has frozen and I can't do anything except turn it off by hard boot. When I plug it in, I have the apple icon and that is all. It was at 43 percent battery life when it happened and my Twitter app was giving me problems. Thoughts?

Second Life failing in Boot Camp for Blackbook

Hey everyone.
I've been scouring the forums looking for solutions to get Second Life running on my Blackbook (4 gig RAM, 2.2 Ghz, the damnable X3100 graphics chip).
So far, I've tried the .xml occlusion fix in Second Life, Windlight, and Secondlife (RC), and it fails every time.
Then, I tried installing a fresh copy of XP under Boot Camp. It won't even let me open SL or Windlight, saying I don't have the proper video drivers. This is weird, because everything I've seen on this forum suggests that the Windows version works fine for people.
I'm about to give the OpenGL MBP workaround a shot but I don't have much faith. Can anyone help me? I'd hate to have upgraded to a beautiful Blackbook only to find out SL doesn't run on it.
Thanks.

Yes, I have. Unfortunately, there does not seem to be alot of activity, and there is nothing in those forums about Second Life.
Since the problems with running Second Life seem to be confined to the Macbooks as opposed to Boot Camp, the questions (and the answers) have been located more here. Hence me posting the thread in this forum.
Thanks though

I just downloaded more then 2000 photo's from my camera into iPhoto. Shortly after that my battery life was depleted and so I plugged the computer back into power and after I opened iPhoto later, I could not find those photos anymore

I just downloaded more then 2000 photo's from my NIKON camera into iPhoto. Shortly after that my battery life was depleted and so I plugged the computer back into power and after I opened iPhoto later, I could not find those photos anymore!! Help where are they? How can I retrieve them or are they lost???
Please help me!!!

Do you see more photos, when you enable "Hidden Photos" in the "View" menu?
And that was afetr I took the connection with the NIKON out of my laptop.
Check, if you really imported into your iPhoto library - is the preference setting "Advanced > Importing: Copy items to the iPhoto Library" active? If not, connect your Nikon again - do you now see more photos?
If you imported into the iPhoto Library, check inside the package:
Select your iPhoto library in the Finder, ctrl-click it, use the command "Show Package Contents".
There will be a folder named "Masters" inside, with subfolders named by year - month - day. Look for the date you did the import and check, if the photos are inside.
If yes, copy this folder to a folder on your desktop to save the photos.
If not, search for a folder "Importing" inside the library. Is it there? Then copy these photos to a folder on the Desktop.
If you found your photos, backup and rebuild your library.
See Old Toad's post here: Rebuild iPhoto Version 11

HT1338 How can I conserve battery life on my new macbook pro? I got it 2 weeks ago and am noticing that the battery depletes quickly. I dim the screen and keyboard backlight & mainly use Safari (multiple tabs).

Appreciate any help!

     My daughter also just bought a Mac Book Pro 13" with the same issue. When we migrated over from the old computer, we brought over only her documents, no applications, and she was getting only about a 2 hour battery life on the new MBP. Somewhere in the MBP threads in this forum someone who was experiencing this same battery life problem said he was told by an Apple Genius in a retail store to try setting up a second user, and then to try working out of that user only. So we set up the second user, logged out of the old user, and the battery life readout is now about six hours after a charge when my daughter is logged in as the new user. If she needs old documents or other files she can always log in as the old user to use them, but she rarely has to go back. Whenever she is logged on as the old user the battery life shows under two hours, but when she she logs out and logs back in as the new user it jumps back up to around six hours.
     There seems to be no need to eliminate the files etc. that reside under the old user. As long as my daughter is logged out as the old user and logged in as the new user, the battery life is much better. Weird solution, but it seems to be working. She is running Lion 10.7.4.
     Hope this helps.

Massive battery life drop after Internet Recovery OS re-install

Hey,
A couple months ago, I made the brilliant decision to try to install Windows 7 with Boot Camp at 3am on a weekend after several days of no sleep (unfortunately, this is one of the least-poor poor decisions I've made recently, but I suppose that's for another forum). Long story short, Og turn on MacBook, Og open Disk Utility, Og click-click, SSD go bye-bye—formatted, every last bit of it (haha, me make pun-pun!). Luckily, ML ships virtually tard-proofed, so there's little I can do besides showering with Bernie (this pun courtesy of the 'lil sis; I'm innocent) to make him breathe his last. This little bit of Apple genius is irrefutable proof of God—praised be his noodly appendage. But ever since Internet Recovery blessed me with Bernie II (R'amen), I've noticed during countless nights lying with him in bed that his stamina has decreased significantly, versus his pre-IR days. I can't give you firm numbers of his endurance before the operation, but now, after even the least vigourous play, he's drained beyond further exertion after no more than 2-2.5 hours. I've tried various tweaks to increase battery life—making sure his mail parts are only shooting off when I work them manually, the same for receiving messages as well, and I've been monitoring his GPU usage; thanks to ML he's much more conscientious about being discrete, and I rarely have to limit him to using his integrated components. (Note: I'm using writing this as an excuse to start an essay, and its foundation really needs to get laid ASAP, so unfortunately the allusions/euphemisms stop here.) Again, I can't give precise numbers about its original battery life, but I was blown away by it, likely averaging at or in excess of the advertised 7-hours. I'm a geek and spent my childhood with eyes never further than a couple of inches from my CRT (and have the vision to prove it), but I really have no f'ing clue what would be causing this. I never doubted that the battery life decreased (and dramatically so), but now that I've started booting up into Windows regularly, any trace of doubt has vanished. Using Windows 8 set on Maximum Performance (and, as I'm sure most of you are aware, Windows only uses the discrete GPU, even when doing nothing graphically-intensive), the battery life is still significantly better than using ML. I've searched and searched and searched and can't find a single reference to this issue online. I'd appreciate any help you can offer. Just in case it's of any assistance, I'll put some might-be-relevant-maybe info below, including things I've thought of that could be the source/contributing to the problem (again, I really have no idea what I'm talking about when it comes to true geek know-how):
- It's a rMBP 15" w/16GB RAM
- When I formatted the HD, I wiped out everything. Yes, obviously there was enough on there for the laptop to launch into Internet Recovery, but I'm thinking that was all that was left. When I've been trying to think of why there's nobody online with this issue, something that's popped into my head is that anyone who knows what Disk Utility does is probably savvy enough (when not sleep-deprived) to not use it to format their HD, or at least to heed to the plenty of "Don't click yes, tardums" warnings that I'm sure popped up as I zoomed by them. And I can't think of many other ways for grandma-level Mac users to wipe their HD, so the lack of online info would make sense.
- This was a couple months back, and I can't remember precisely the OS version when all this went down. I'm certain it was ML since I think my rMBP shipped with 10.8.0 (if not 10.8.1, if any did), but it could have been anything between 10.8.0 and 10.8.2. I'm pretty sure it wasn't 10.8.0 since I remember updating to 10.8.1 very soon after purchasing the laptop over the summer, but again, not certain.
Alright, that's it. I'm sure this post doesn't meet forum standards for plethora of reasons, but I'm a poor little private liberal arts university student who is desolate now that his $3,000 laptop isn't getting top-notch battery life, so mods, please dig deep in your hearts and don't delete. Thanks, yous da best.

There were a number of posts from folks with various models about a downgrade in battery life after an upgrade to Mountain Lion - so you aren't alone. However, since you're still under warranty, I would take the machine to your local Apple Store or an AASP and have them diagnose the problem. Could be that your battery just isn't up to par (and I'm assuming that you've all updates installed?)...
Good luck,

Battery life issue, phone shuts down

HI I have an iphone 4S running 6.1.1 and with 10.6GB avail space running 3G on the Fido network. Had the phone for less than a year and it was sent to me as a refurbished
My phone shuts down before it gets to 0%. Sometimes it lets me get to 0% and does a normal shut down, but in some cases it will suddenly just shut down and claim it has no battery life left, then when plug in loads up right away, exactly with all the same apps open and with a good chuck of battery.
Today for example
- Was at 70% when went out on a bike ride
- 2 hours later and after some tethering and listening to music it shuts down all of a sudden while looking at a tweet
- Try to turn back on, says its out of battery
- Get home and plug in, starts up at 17% right back at the same tweet

I have the same issue with the same 4S. I thought it was a bug with the camera because it would happen while I was in the middle of taking a picture. The phone would shut down and after attempting to restart it prompted no battery life. But once I plugged the phone in it would start up and show the proper battery % left on the phone.
Another forum on here stated a probelm is with the cold weather which was cauing the battery to lower in tempature, falsly causing a depleted percentage which forced a shutdown. They said all they had to do was let the phone warm up and it would reboot back up just fine.
I thought it odd but most of my issues were when I was outside. That is until just last night when I was in my kitchen taking a picture of something on the counter and it again shut down. I had to plug in the charger, boot it back up and once back up I went right back to the kitchen and tried again and it happened again. So I plugged it in again rebooted and then unplugged the phone and let it sit about 10 minutes on the counter and then tried again and it worked. I am not sure the cold had anytyhing to do with it this time because I had been home a couple of hours already and my home is 70 degrees. It is frustraing. I find myself caring a backup battery to plug in the phone if and when this happens when I am away. Not a good solution.

Boot camp 3, windows 7, 13" unibody macbook and keyboard function keys....

after some screwing around (disable user access control, install tweak util to allow unsigned drivers) most features of my macbook are now working in windows 7. battery life looks abysmal as it was in vista, but i'll deal with that later.
the major glitch at this point seems to be the keyboard. the boot camp manager in the system tray has the keyboard option, which does nothing. pressing fn-f1, f2, etc does nothing except bring up help or the corresponding f-key value for windows. i manually reinstalled the apple keyboard driver, but this obviously isn't a driver issue - it's a keyboard manager issue. i notice that there is no more kbdmgr.exe in boot camp 3... at least as far as i can tell. what process is now responsible for these keyboard functions? it would be really nice to be able to eject discs, use volume, hit ctrl-alt-del, etc!!
thanks in advance to anyone who has figured this out.

to sum up: actually got 7 running, but all just to a certain extent:
Keyboard works rather well, even though the backlight cant be fully switched off in low light conditions. Low light is considered even if its still bright enough to easily read the keys labels, but thats just the same as in OSX.
The trackpad works half way, as a poorly working standard touchpad with + two finger scrolling (way too quick) + two finger right click. Tapping works, but dragging and tapping doesnt work technically (clicking a button then quickly moving the cursor is misstaken as dragging, feels inferior in recognition to other touchpads). Multitouch stuff doesnt work at all, which is a pain seeing that touchpad.
Sound quite works, but if u reboot the macbook in having the sound muted u need to reboot again with sound switched on to make the sound play through the speakers.
CD eject seems buggy too.
Battery runs like 2,5 hours (4 hours in OS X). (Must be a driver issue, windows CAN run such a notebook for 4 hours too, just consider all those lenovo thinkpads)
Why the **** does installing Windows on a Mac feel like installing Linux on a random PC...
If anyone has solutions/hints regarding the sound or the trackpad let the world know!
Coolest thing ever would be to get synaptics drivers running with the Apple touchpad. Could be possible, since in Linux as far as i get it the macbook touchpad is driven by synaptic drivers as well. Would need some fiddling though, maybe someone manages?!

A Potential Convert Looking for Some Help with Boot Camp

I posted this in the Macbook Pro forums, and somebody directed me here. Hopefully you can help me with my questions.
Hello,
I have been a PC user ever since I can remember. I have loved the operating system and have had a Dell Laptop for 4 years now without any problems at all. I have no qualms with the Windows Operating Systems. But, it is time for me to get a new laptop, as I will soon be heading off to college. I was thinking about getting another PC, as they are significantly cheaper than the lower-end MBP that I would get, but I was also thinking about trying out a Mac. I plan on using this laptop for most of my undergraduate education though, so I don't want to buy something and find out it isn't what I want or I can't use it. So, if you would help me, I would like to ask some questions about the lower-end Macbook Pro, and I may just end up getting one.
First things first, I am going to be going into engineering, likely mechanical or systems, at either WPI, Northeastern, or Tufts. Ah the experience of choosing colleged. I know Tufts uses AutoCAD, WPI uses SolidWorks, but I am not sure which Northeastern uses. Either way, I most certainly will be using a CAD program. I know that most CAD programs do not work on Macs, so I will likely be using Boot Camp. I have though seen on these boards that the AutoCAD licensing does not work with Boot Camp, or that some users have faced major problems with it. If this is so, then it is highly likely that I will be unable to get a Mac as that program is going to be an absolute necessity. Even if this is just a small percentage of the population, I do not want to find mine being of major issue. For those of you who have gotten it to work, how difficult was the installation, and have you had any issues with AutoCAD or the like? With this in mind, would you even suggest that I get a MBP?
Another Boot Camp question. I have read many posts on these boards discussing different partitioning options, yet I still am unsure what they all mean. I expect to use the Windows side for more than just AutoCAD. I likely will install some games on it for when I am bored, and Microsoft Office, as I do not wish to spend the extra money buying Office for Mac and I need to have the versatility of Excel that I have heard is not found in the Mac version. What is the difference between these two partitioning types, which would you recommend, and how much storage should I partition if I get a 200GB hard drive?
Yet another Boot Camp question, sorry for so many of these. My friend who has a Mac lauds it for its security, nobody makes viruses for Macs. As I will most definitively be using Windows in Boot Camp, would this compromise this security? I know it will be Windows, but I still imagine that it would be encoded somewhat differently then normal, but I could be wrong. Also, if it is possible for the Windows portion to get a virus, could that affect the Mac portion?
Also, I don't use an iPod. I suppose I always thought they were overpriced for what they do. Instead I use an Iriver Clix 2, and I love it. The only thing is, I use Windows Media Player to sync it with my library. I know many have qualms with WMP, but I personally favor it more than iTunes, but that is just me. I do not believe that you can download it for a Mac. If I were to download it for the Windows portion, I am assuming that I would have to switch to Windows in order to listen to my music then, correct? I can also add music to it via Windows Explorer. Can I do so through the "Finder"?
Finally, is the battery life any different when using Windows than when using Leopard? I will likely be using the Windows portion in the class room.
Sorry for the long-winded post, but I am certainly hoping that I can get some solid answers to make an educated decision before getting my next laptop. I would like to thank you very much for any help that you are able to give me. I do hope you can help me quickly. Thank you.

I can't answer all your questions, especially not anything having to do with CAD.
I still imagine that [Windows] would be encoded somewhat differently then normal,
No. Windows is Windows. You will need a good Windows antivirus, firewall and antispyware program. It is unlikely that a Windows virus will infect the Mac partition because, ordinarily, Windows doesn't know how to do anything with the HFS+ formatted Mac partition. However, the existence of products like MacDrive means that it is possible to teach Windows how to write to the Mac partition, so I see no reason why a virus could not be programmed to.
If I were to download it for the Windows portion, I am assuming that I would have to switch to Windows in order to listen to my music then, correct? I can also add music to it via Windows Explorer. Can I do so through the "Finder"?
Yes. Probably/yes.
Finally, is the battery life any different when using Windows than when using Leopard?
Yes. Windows does not have the battery management that Leopard has. The battery runs down much quicker in Windows.
You didn't ask, but depending on what kind of engineering you want to study, you may be interested in, or even need to, use some flavour of Unix/Linux. On the one hand, you could always create a partition on a PC--or wipe Windows--and install Linux on the PC. That could even be a good learning experience. On the other hand, Mac OS is Unix, but preinstalled. So with a Mac, you would already have a platform for writing shell scripts, you would have Perl and Python built-in, you would have an IDE (XCode Tools) for C/C++/Objective C/Java as well as gcc and make tools already on the disks which come with the computer, and so on.

Bootcamp Windows battery life - USB power problem?

Hi,
While the battery life on my MBP is ok under Windows (3 hours), it's not great when compared to booting into OSX where I get at least 30% more. It's easy (and right) to blame Windows inefficiencies when running XP or Vista, MS have massively improved energy performance under Windows 7. Looking into this a bit, I've found there is now a new tool to help investigate energy problems:
POWERCFG /ENERGY
The generated power report shows that I have five cases of "USB Device not Entering Suspend". In otherwords (even though I don't have any devices plugged in) the USB components are burning at full power and not allowing Windows to suspend them to save energy. This may well explain why I'm not getting the battery life I could be, and it's really not Windows fault.
Does anyone else see this? I'm on MBP5.5 w/ Win7 Pro x64.
Hopefully a future Bootcamp will enable full power management support..
Cheers,
Chris.

Hello,
the core of the problem is the quality of the Boot Camp drivers.
The boot camp drivers allow very limited power management, therefore there is no real possibility to run Vista or WindowsXP without heavily using battery resources.
I don't think there will be any improvements in the future as Apple in not really committed to deliver better drivers (the present BootCamp power management drivers have remained virtually unchanged since BootCamp 1.2 beta, March 2007).
Just have a look at the threads about BootCamp especially about the problems that are plaguing the new MacBook Pro (mid 2009) i.e. poor sound quality and no microphone in Windows.
Cheers
Luca

SpeedStep in MacOS = no whine & extended battery life

As a lot of you might have tried WindowsXP using Boot Camp by now you probably noticed that the whine disappears when using windows well this is because Windows XP makes use of Intel's SpeedStep technology (unlike Mac OS 10.6) and when idle it lowers cpu speed to 988Mhz (on my 1.83Ghz) and it also lowers the cpu voltage to 1.0v down from 1.4v I beleive this is what elimites the whine. There has been a person who goes by the name "Cryptonome" who has been working on a way to control the cpu frequency in order to eliminate whine and increase battery life, please visit http://www.Cryptonome.com for more information.

Mac OS X does indeed support SpeedStep, and uses it
extremely aggressively.
The CPU whining noise is most likely related to C
state management ("nap" in Mac OS terms), which is
related but orthogonal.
Typically, noise like the whine being discussed ad
nauseam here is radiated from power supply components
(capacitors and magnetics most of the time), and it
is caused by sudden, repeated fluctuations in the
current being drawn from the power supply.
SpeedStep transitions don't typically result in
sudden changes in power supply current; when the VID
bits change the power supply ramps up or down a
little, and the load on the power supply changes
proportionately.
Conversely, on a transition into or out of C4, the
CPU is being switched almost completely off, or on;
this represents an enormous change in load for the
power supply. If the power supply is making noise,
these large changes tend to result in a much louder
noise than the smaller changes that you would see
from a SpeedStep transition.
Note that the effectiveness of the Photobooth "hack"
tends to support the argument that it is nap and not
SpeedStep that results in the noise; realtime
applications like Photobooth are likely to be
inhibiting nap for latency reasons, but very unlikely
to be inhibiting SpeedStep.
I'm still trying to grok all this, so please humor me.
Based on the above, the speedstep state transitions are resulting in power fluctuations, leading to the whine? And the reason many don't find any whine in WinXP is because (speculation) it may not be doing appropriate SpeedStep transitions, resulting in additional heat (reported issue) and lower battery life in XP (but no whine)?
All that seems to make sense. The only thing that throws me off are the posts (potentially wrong) from folks claiming that they get BETTER battery life w/ XP (implying a more mature SpeedStep implementation in XP -- which is entirely possible), and they still have no whine (sounds impossible given everything above). Sorry for the long post, but from my understanding both can't be true, unless I'm completely misunderstanding the above. Can anyone provide insight?
