    I recently upgraded from Lion to 10.8.2 on my out of warranty late 2008 15" MBP. I am noticing both the battery drain... especially overnight, about 30% last night in sleep mode... and a faint but noticeable flicker on the LCD panel at low illumination. Tried PRAM and SMC reset with no effect. Took to Apple store and the hardware checks out OK. The battery is surprisingly OK -- 95% health according to Coconut Battery. The machine is usable so I am not looking to sink a lot of money into the problem.

     

    What advantage does a clean erase and install offer over the ugrade I did? Is it likely to make enough of a difference to justify the time? If its going to be truly clean should I reinstall apps from scratch rather than from Time Machine?

     

    Is a new battery likely to make much improvement over my old but relatively healthy battery?

     

    Thanks in advance.

     

    First, if your battery's health is 95% there's no reason to replace it.

     

    An OS update is usually the way to go although I tend to use the combo update rather than the standard Software update (now from the Mac App store) to ensure I'm getting everything possible updated.  However for a lot of folks here (including me) a clean install was the only thing that got our MacBooks back to working normally.  It didn't work for everyone but for quite a few.

     

    An OS update can highlight issues that either weren't apparent or didn't exist previously.  A clean install ensures that everything is "new".  An update means that everything on the current setup is left intact and only particular elements of the OS are changed.  A clean install or "scrape and pave" means that all of the OS, all of your preferences, all of your apps, everything is wiped out...there's no "cruft" left, at least with respect to the software, to cause problems. 

     

    For anyone performing a clean install I've always recommended a manual setup; avoid restoring from a backup.  Re-download apps manually import files, etc.  It's a bit of a PIA it but it also ensures that if there were any issues with the previous installation, apps, preferences, permissions, etc., that they aren't carried over to the new installation.  For a Mac that's having real problems it's well worth the time IMHO.

     

    That said, your MacBook has updated EFI Boot ROM and SMC versions available.  If you haven't updated both that's where I would start.  These are firmware, not software updates, and the OS depends on them being current.  More here:

     

    http://support.apple.com/kb/HT1237

     

    Reset the SMC and PRAM after updating and see how things go.  Those two steps may not be necessary, but it can't hurt.  If that doesn't make things better, then yes, I'd go for a clean install, reset the SMC afterward and hopefully that'll do it.  It sounds like you're pretty savvy with these things, so it shouldn't be too difficult and you'll end up with a more-or-less "brand new" MacBook.

     

    Keep in mind that after a clean install Spotlight will be indexing everything and that takes some time, uses a lot of CPU and battery power.  So it will be a while before things get up to speed.  Also, as I mentioned above, give it a good 3 to 5 charge cycles and see if it doesn't start behaving normally.  You can find the battery life specs for your MBP here:

     

    http://www.everymac.com

     

    Follow Apple's guidlines with respect to battery maintenance/charging:

     

    http://www.apple.com/batteries/notebooks.html

     

    If you want to keep track of how your battery is doing (and compare it to others with your same model) you can install the free MiniBatteryLogger App:

    Hope that helps and best of luck!

    I have a new retina mbp and am experiencing all of the above - never had more than 3.5hrs out of it (and never had anything other than mountain lion so dont know how that may effect it)

     

    If Apple dont fix this soon through an update - Im taking it to a store and asking for a new one that actually gives me the 7 hours that is advertised!

     

    Ive been there twice now - once to check the battery (which they said was fine). I then went back to book an appointment to change the battery (even though they said it was fine) the new guy told me that I shouldnt bother as Mountain lion wasnt perfect yet and I should wait until the next release.  (he told me apple have 2-3 update release cycles which clearly we all know isnt the case)

     

    If the next software update doesnt fix it - im asking for a new machine (as Im lucky enoough to have a machine that is within warranty)

     

    PS: People are saying that this is a minority issue - personally Im not sure it is. I work with loads of people that have macbooks and EVERY ONE has experienced battery problems since updating - its just they havent bothered talking to apple about it

     

    Sorry to hear that your MBPr isn't behaving as advertised. 

     

    FWIW, the "new guy" was correct about release cycles.  Mountain Lion has actually had three updates already, 10.8.1, 10.8.2 and a 10.8.2 supplemental update and there will be additional updates to follow.  There have also been EFI and SMC firmware updates.

     

    So you (and apparently EVERYONE you know that owns a MacBook) can try some of the suggestions posted on this thread, wait for an update or if they're lucky enough to still be in warranty, take it back and demand a replacement.

     

    Me?  I'd keep escalating it with Apple until I was satisfied.  You deserve a machine that works as advertised.  Your call of course.

    ill do just that. I wont hold my breath for an update any time soon though- Apple certainly dont release regular updates in my experience (at least the ones you get through the software update function).

    If you're looking for a couple of dozen updates a week like Microsoft/Windows users experience, then no, that doesn't happen.  That's a very good, not bad thing.  It means that the OS is stable, doesn't require continual patches and security issues are almost non-existent.

     

    Best of luck and let us know how things go.

    Thanks, that is helpful.

     

    Just checked and the Boot ROM and SMC versions are up to date -- it's an MBP5,1 and I have MBP51.007E.B06 and SMC 1.33f8.

     

    I will run the laptop through a few charge cycles and see what happens before I consider a clean install. As I say it's old, and it works, and its hard to say if I can eek any more out of the battery. I'm not experiencing "real problems" at this time.

     

    I was going to consider upgrading my main unit, a slightly newer MBP5,4 15" mid 2009 (which has a brand new battery). But I think I may wait and see. I don't need two machines with these issues.

    I agree. As one who has been doing large numbers of Windows updates every month on desktops and servers, it's a pleasure not to have a constant barrage of securlty updates.

    I really like Mountain Lion's new features on my iMac...and now my MacBook Air; works nicely with my iDevices too, but there isn't anything I couldn't live without.  So if you don't need to update, I agree, I'd just wait a bit and see how things go.

    All I was trying to say was that its anybody's guess when apple will release their next update there was over a month between 8.2 and 8.2. They've certainly never given the impression that there's a regular schedule that they go by, so we could be waiting months before the next.  My biggest annoyance is that apple are refusing to officially acknowledgment there's a problem at all when there clearly is. If they acknowledged the problem and said they were looking into it then at least I could rest assured it was being looked at. Currently it feels like going to the doctors and being told there's nothing wrong with you.

    I'm guessing that you're new to Apple.  Welcome!  I'm really sorry that you've run into an issue.  Having been through it I understand the frustration.  As a long-time enthusiast I can tell you that these things are fairly rare and historically have always been addressed, but, as they say, these things happen.  Your expectations on a number of levels is a bit confusing though.

     

    I understand that this thread is long, but with all due respect, you should try reading some of it...if only the last few pages before Smeeking.  If you do you'll quickly learn that Apple is aware of this issue and have been since August.  They've contacted me and a number of others here directly and they are continuing to work on it.  FWIW I don't know of any company anywhere that takes this kind of proactive approach to their business.  So they have in fact acknowledged the problem and they are in fact working on it.

     

    If you're expecting Apple, or really any corporation to somehow "acknowledge" a minor problem (albeit a major problem to you), you're going to be continually disappointed.  As comforting as it might be, that's not how the world works.  Remember, there are millions of MacBooks running OS X 10.8.2 without any issues (including mine now).  The idea that millions of people have the same problem and just aren't saying anything about it isn't even remotely plausible IMHO.

     

    You are correct though, it is anyone's guess as to when Apple will release the next update.  It's anyone's guess as to when any company will release any update really.  So I'm confused...a "regular schedule"?  An update is issued if and when an update is needed and/or is ready for release.  Some updates are issued within days of each other, others months later.  When we'd like them to appear is often never soon enough, but why would a company "schedule" an update unless, well, there's an update?  

     

    So if it helps, rest assured, "it's being looked at".

    Sorry to be a smeek (never been called that before :) ) but yes - 170 pages was quite a daunting prospect. I am indeed glad to hear that apple are aware of the problem I wish they'd have been a bit more forthcoming at the apple store - it almost seemed like they knew there was some kind of software problem but weren't willing to admit it (suggesting i replace an apparently healthy battery didnt help my cynicism) i will await the next software update with bated breath.

    Microsoft has a once a month update schedule so I am not sure why you would be getting so many all the time?

    I personally would rather have more frequent updates, because that way a security issue is patched much sooner.

    Many security experts get upset when it takes Apple so long to fix a security problem.

    So back to the whole battery issue. I think Apple's updates so far have done some good and its hard to say why it has helped some more then others. Maybe they have more things running in the background or maybe their Mac has other issues such as more cycles of battery or other hardware issues.

    Richsadams makes a good point. If you have a problem similar to others but does not seem to be helped by a update or other Apple fixes that has helped the majority of others. Then its time to seek out a Apple Genius or at the very least contact Apple care and maybe they can help you better. I think these forums can only go so far and if basic solutions do not help, then you have to look further.

    I hope you don't misunderstand, I despise name calling.  You're certainly not a "smeek" (not sure if you even could be a smeek), but simply someone posting without reading the previous posts in a thread...which is known as "smeeking".  It's kind of like bursting into a conference room, late for a meeting and blurting out something that everyone's already discussed. 

     

    With respect to the front line folks at the Apple store not knowing anything about this, that's not the first time someone's posted a similar story.  The same apparently happens with an initial phone call to Apple Care.  As that seems to be common it reinforces the notion that this is not a widespread issue.  If it were it wouldn't be long before every Apple CS employee would run into it...repeatedly.  Of course some subscribe to the "Apple conspiricy theory" whenever something odd happens.  Hmmm...if this keeps up I may need to retrieve my tinfoil hat from the cleaners! 

     

    I do hope that this issue is fixed for you and those that are still suffering sooner than later.  I'm quite confident that it will be.

    Agreed...Apple does seem to have drug it's feet for a couple of past security issues.  I'm not sure if it's because they are so rare and they're caught off gurard (not likely IMO) or if they are making sure they get it right and don't have to revist it at a later date...the more likely scenario.  I suspect the last explaination is what's taking the next update for 10.8 so long.  Only time will tell.
