    Ok, I booted keeping cmd+shift+v down, and I can see that it stops at bootcachecontrol: unable to open /var/db/boot cache.playlist: 2 no such file or directory

     

    Otherwise, I need to wait until tomorrow, to get my external hdd.

     

    Thanks ct!

    If anyone interested... I've made a backup of my Snow Leopard and installed Lion again. I got about 4h30mins on battery instead of 8h - 8h 30m (on MacBook Pro 13 2010). Nothing have changed with Lion since summer. I'm very disappointed. No fix for several months! I'll get back to Snow Leopard for now. I'm not touching Lion until at least 10.7.5.

     

    And I was thinking about buying MBA 11 but they all have preinstalled Lion (new models I mean). Anyone knows, do they have same battery problems?

    hello ı have problem about my MBP draining battery because of upgrading to lion occuring Daemons which are not compitable to lion as ı read all the forum sites about this issue i need to remove them which are using cpu hidden  but ı dont understand how ı can see them

     

    https://discussions.apple.com/thread/3191543?start=0&tstart=0

     

     

    written like that

     

     

     

    I was all set to go back to SL, but decided to look at the forum one last time.  As with many others in the forum, the problem for me was AGAdminService daemon.  (You can't see Daemons from the Activity Monitor).

     

    To see what Daemons are running and what's eating your CPU, run this: (ı dont understand how to do)

     

    top -o cpu(where should ı write it)

     

    For me, this was at the top: (for me ı think ı will see something which are reducing cpu and battery life)

     

    646- AGAdminServi 100.1 05:44.39 7/1   1    76   N/A   N/A    N/A    N/A

     

    To kill the daemon, run this:

     

    sudo launchctl unload -w /Library/LaunchDaemons/com.citrix.agadminservice.plist

     

    PLEASE helpe me ...

    Hi, let's tell me a story about my friend's mid-2011 13.3 i5 MBP. She has seen "Free upgrade program" at Apple site and decided to install Lion. After that, MPS's behaviour looked like battery is completely taken out: it stopped functioning right after unplugging magsafe... I tried to repair it, have booted to recovery with cmd+r, unplugged magsafe and MPB worked normally. I've begun Lion's installlation - everything was OK. But right after the end of installation, after reboot things have turned back. SMC reset, etc haven't worked out.

    Cheers applecare service for fixing this issue with some unknown way

     

    After that, not so long ago I've bought late 2011 MBP with Lion and now I am new sufferer of it's 3 hrs battery life. So does the friend of mine after Lion upgrade.

    Just to add my two pennies: early 2011 standard MBP 15" Upgraded to Lion a couple of weeks ago and have shocking battery life. Tried the fixes I've found by surfing about; no improvement.

     

    Come on Apple. Pull your bleeding finger out.

    I've been subscribed to this thread since about page 60. I pulled Lion off my 13" MBP (2009) but kept it on my Mac Pro.

     

    I work in a community college and see lots of student laptops and have seen the Lion battery issue on them repeatedly and consistently. However, yesterday I was helping someone who had a brand new 13" MBP with 10.7.2 and it was showing 9.5 hr battery life. That was the first and only indication I've ever seen that this may not be a universal problem.

     

    Personally, I really dislike Lion for a lot of reasons beyond the battery issue and wish that I had waited longer before overwriting the SL backup of my Pro. I think that it's Apple's worst software blunder since System 8.0, which they really didn't get to work right until 8.6.

    That was totally your decision. Don't blame anyone or anything else. I love Lion, and although I will not be going back to Snow Leopard, I still have a full backup clone. And if you read the posts on the Snow Leopard forums, people are STILL somplaining that SL 'destroyed' their machines sine upgrading from Leopard. It happens every update, and although this battery issue is effecting a certain few, and may well be machine specific, a lot have resolved it. If you dislike Lion, and so not have a backup of SL then that is user error. Yours.

    Apple may or may not fix the reported battery issue in it's next update, who knows? But if they are, then that will be the best way to fix it, not the multitude of hacks that can be found through this thread.

     

    Good Luck

    ...[P]eople are STILL complaining that SL 'destroyed' their machines sine upgrading from Leopard. It happens every update, and although this battery issue is effecting a certain few, and may well be machine specific, a lot have resolved it.

    How certain "a few" have been affected?   Why do you suspect the issue is machine specific -- how many machines, the dozens reported here or more?  How have the "lot" resolved it?  Most important, where is is there a report how they did that? 

     

    Yes, people are "STILL complaining."  They need concrete help, please.  Thank you.

    Yep and after 125 of mostly useless posts here, there is not much on offer. If this is the only thread you base all your facts on, then you will really never have a machine that runs well. There are other threads here if you 'search'. There are people in this very thread also who have admited to fixing their problem, yet about half a dozen of you make up (5% of the most recent pages. You do the maths, and perhaps just wait until you can give a stable fix for your problem instead of confusing the issue for others.

     

    Cheers

    If this is the only thread you base all your facts on, then you will really never have a machine that runs well.

    I count at least a dozen threads on various topics dealing with these and related issues.  That's just in the Apple discussions.  You can find the same on many of the popular Mac-related websites and forums. 

     

    My machines run great.  (I restored SL.)  I'm an observer because I'm interested in how the conversation is evolving and what Apple's response will be.  And how people are learning to solve  problems on their own in the face of Apple's apparent "leave it to us, we make life simple" attitude.

     

    If you find the last 125 comments useless, why hang around?  To condescend?  How royal.  Good night.

    I did a clean istall following your posts and for some days I haven't install any other applications than the Lion natives. Didn't see any improvement.

    Yes, you can just put the deleted files back.

     

    Have a look at

     

    "Restoring data from Time Machine backups"

     

    here:

     

    https://discussions.apple.com/message/17262837

     

    I guess you will have to boot from the recovery partition (command-r) to get this done.

    It's me, again, a little bit OT.

     

    Got my external HDD, booted with cmd+r, selected 'Restore from Time Machine backup', but the next screen says that  'Restoring from a backup erases the contents of the selected destination disk'. My backup is realy old, and I don't want to loose the files that I have on the computer. I am looking for a way to put back the files I deleted (I made a copy before and if I coud start the computer I may be able to put them back).

     

    Any other ideas?

     

    Thanks in advance for any suggestion.

    Have a go at a safe boot first by holding the shift button at the startup sound.

     

    Otherwise if you know how to use Terminal, you could use this to move or copy your files back after starting up from the Recovery Partition.

     

    Or if you have another bootable partition somewhere, use that.

    Safe boot does not do anything.

    How do i start it from the recovery partition? I have as options Restore drom TM, reinstall, get help online and disk utility.

    AFAIK you can only start safe mode by pressing and holding the shift button at startup (edit: press it once you hear the startup sound).

    What do you mean by "it doesn't do anything"?  Are you seeing a progress bar in the bottom half of your screen?  That tells you that you are booting into safe mode.  It takes quite some time to start that way, as it's checking the disk(s).  Did you see the progress bar?

     

    You also have Terminal in the recovery partition, but if you've never used Terminal, I would be reluctant to suggest to go that way (edit: but I can explain further if you want me to - edit: do you know where your files are located [the ones you've moved?]).

     

    Re-installing should do the trick too, but it might take quite some time downloading the 4 GB from the server.

     

    I assume you don't have a clone or another Mac?
