Why my MacBook Pro's Spring 2011 Life span dropped from 1000 Cycles to 300 ?

I have a 15" MacBook Pro, i7, 8GB Ram since i have done a System update , I have noticed in Watts application that my lifespan dropped from 1000 to 300 !!!
How is that possible ???

if you're talking about cycle count, it starts at 0 then goes to 1000. not the other way around.
if you have 300 cycle count, that means you've been using your macbook in battery mode a lot of times.
try keeping your macbook plugged in all the time if you're close to a power outlet. leaving it plugged in will not overcharge your battery. it stops charging once your battery is 100%
once in a while, use it under it's own power until it's down to 80% then charge it back up to keep your battery in optimal condition.
good luck

Bootcamp: Macbook Pro 13' late 2011 won't boot from USB, no superdrive.

Some months ago I replaced the superdrive in my Mac with a SSD. This resulted in my Boot Camp not working, therefore I deleted it. The thing is that I have been wanting to install Windows again but it just seems impossible. I find myself pretty confident at a computer, so it frustrates me really.
The thing is that no matter what I do, everytime I boot up from windows installation USB, Windows 7 and 8, or something like it, it gives me "No bootable device - insert boot disk and press any key". I searched everywhere to solve this problem and nothing helped. I tried different images, even 32bit of both Windows 7 and 8. Even tried with my original Windows 7 64bit dvd. There is no more solutions out there on the internet I can find, so therefore I'm shouting out for you guys!
Here is what I already tried.
- Altered Bootcamp so it would create a bootable USB from a windows image. Worked like a charm, except that it would boot up to "No bootable device...". And the USB didn't show up in the boot menu pressing alt when booting. Tried four different usbs and the same story with all of them.
- Tried with a SATA-USB connector to a 250gb harddrive, "No bootable device...".
- Tried to make my own bootable USB on a Windows-computer with bootsect.exe/nt60 and everything, also Microsoft own program for the purpose, "No bootable device...".
- Tried with making a partition on both my HDD and SDD in the Macbook to boot from, "No bootable device...".
- Tried transfering all the files of the image to the created boot camp-partition, "No bootable device...".
- Reset PRAM with cmd+alt+p+r, "No bootable device...".
- Installed rEFlt, because the standard boot menu would not recognize anything else than my Macintosh SD. It did work so I could see my windows devices but still didn't boot, "no bootable device......".
- Tried to boot with rEFlt with all the before mentioned methods.
- I even desperially installed Windows from a pc on the HDD and tried to boot it on mac.... same **** story, "No bootable device...".
I really hope that someone can figure this out, because I'm ripping my hair out. I simply can't get this **************** to boot anything Windows .

Can I rebuild the USB flash drive using the discs that came with the new Macbook and if so, would they be the resulting USB flash drive be backwards compatible with my older Macbook Pro?
Yes. The version of Mac OS X that shipped with the new MacBooks and MacBook Pros is newer (even though it's still numbered 10.5.5) than the version of 10.5.5 that's available from software update. You will have to startup the MacBook from the original install disk that came with it and choose to install Mac OS X onto the USB drive. NOTE: If you want to keep any software or files that were already saved on the drive, choose only "Archive and Install" or "Update" options. (Not the "Erase and Install" option.) In my experience, though, the only option was to "Archive and Install".

It is for the MacBook with built in flash storage.

Macbook pro (15" - end 2011) battery life only works 3 hours - can you help me!!?

Hi since i updated to Mountain Lion, my Macbook pro 15" (december 2011) only works for 3 hours instead of 5 hours with Lion.
I've been waiting for 6 months now a release from Apple to fix this. Are you planning to do something for users like me?
for reminder number of battery cycle as up to today = 131...
Is there someone who can help me? or facing the same problem?
Thank you

Apple doesn't read the threads. File feedback is probably the best way to reach them. You won't get an answer.

Macbook Pro 13" Early 2011 Lag Spikes

Okay let me just brief you on my Macbook.
In September 2011 i bought a Macbook Pro 13" Early 2011 model, 4GB RAM, 2.7GHz Processor, you can get the rest on the site.
( http://support.apple.com/kb/sp619 )
I bought it as a ex-display model, so you can imagine it already has some milage from it.
Through the (almost) 2 years i've had it, apart from the odd overheat shutdown, and a 1 charger replacement, it's been no hassle, even with me constantly shutting it and moving it. It seems that all the issues are coming in bulk.
I generally use the laptop for gaming, mostly World of Warcraft, sometimes Minecraft, and lately Starcraft, and Spellforce on BOOTCAMP or virtual machines.
About 2 weeks ago, the laptop started refusing to charge, i couldn't understand if it was the charger (as i only replaced it a few months earlier and the cable was still in perfect condition) or the port itself in the laptop. I took my laptop to an Apple store, found it was the Magsafe on the cable, replaced it on the spot, but the reason why i'm saying this is i'm wondering why it broke so quickly, and if lack of power has anything to do with it.
I've grown a liking to Spellforce so instead of having to restart into the Windows side of my Mac, i just use the Virtualbox Virtual OS i already have set up from when i used to work from home and have to use certain software on windows because Wine just couldn't cut it (and lets face it, Mission Control is awesome, then you go on Windows and everything just seems to cluttered). So i read the default specs for the game on Steam (2GB) so i give Virtualbox 2GB, but this was a MAHOOSIVE mistake, because as soon as i clicked start, it's been a down hill spiral.
The computer immediately started lagging, to the point where the laptop was actually unusable, so i force restarted it by pressing down the power button for 5 seconds and i let it restart. After it booted, everything seemed fine (i expected nothing else) so i decided to only give it 1GB of RAM, and just turn down the settings to the lowest possible (which is something i've had to do with World of Warcraft recently. It used to be able to run on Ultra when i first got the laptop, now it struggles on low and if i have a browser up at the same time). Again, big mistake, it lagged to unusability. So i restart again, but this time it takes 5 minutes to boot, and once booted everything is so slow, so i decide to re-install the OS, so i get my flash drive and spend the next hour moving things over from my user folder because when i would try to move a folder that had 5+ files or something that was 100MB or larger, it would error out saying a certain file couldn't be read or written, and would cancel and remove everything else that was transfering at the time.
So i restart but boot into the recovery option, and do a refresh the OS, and i let it download and install. I was surprised to see when it had all completed that it still had all my files, but it still ran slow, not as slow as before but definitely not as good as before, i would estimate at quatre the performance. So i assume that Virtualbox must have editted some system setting and my Mac thinks i only have 2GBs of RAM and not 4GB, so i search on how to reset the bootloader, and i was tried the alt + cmd + r + p, but after that when it booted, it came to the wallpaper but i was getting these popups that Finder had unexpectedly quit, so i click Okay a few times, they keep coming back up, so i look at the details and it says that the app had failed 500+ times before.
So i put my Snow Leopard disk in, use Disk Utility and use erase on my Mac OS partition, then i re-install Snow Leopard, then i download and install Mountain Lion again, but the snails pace remains. I do alittle more research and someone suggested modifying the partition size by a few gigs or so to re-write it and reset certain variables attached, didn't work, even after a reboot.
So yesterday i just put the Snow Leopard disk in, and i remove both partitons (Mac and Windows) and i make one partition. I install Snow Leopard and then Moutain Lion, and so far it appears that everything it back up to speed... however, i've been keeping a keen eye on Activity Moniter and "top" in Terminal, and my CPU usage and RAM usage are always relatively low. I always seem to have 1GB-2GB RAM free, and my Idle CPU always seems to be above 80%-90% but i'm getting these weird lag spikes. I notice it most when i try installing World of Warcraft again, the download speed averages around 3MB/s (my ISP is Virigin Media and i get 60Mbs/s fibre optic so i know it's not my connection failing) and then the app seems to freeze (stops refreshing the average speed, and then about 5-10 seconds later, it starts refreshing again but it's at 12-50KB/s. This also seems to happen a lot when i use web browsers.
I have noticed something new, literally only about 30 minutes before i started writing this. There is a noise that happens every 2-4 seconds, it's pretty regular, it sounds like a grasshopper, or other chirping bug/insect inside my laptop. It sounds like metal scraping against metal, which is worrying. It's coming from the right hand side of the Magic Track Pad, which is where i believe the Hard Drive is. I've looked online and this seems to be a sign that the harddrive is dying.

Yeah, the problem has been solved.
Unfortunately, the solution is buying a new storage device.
So if you're having these issues, i tried almost everything consumer possible, that's free anyway, and the hard drive was just too faulty to work properly. So backup all your stuff whilst you still can.
I bought an SSD for around £80, only 120 gigs of storage, but i have iTunes Match so i don't need to have my films and music downloaded.
If you're very mobile with your laptop, then i suggest getting an SSD. Lugging about a laptop with a storage device with moving parts is very very risky.
As soon as i got a new storage device, everything was back to normal. It was like it was new again.
Anyway, sorry i can't give you a free solution, but it's the only solution i got.

My Macbook Pro (15" early 2011) got blue screen every i normally booted it. It only can enter the OS when it's in safe boot. Solution please.

My Macbook Pro (15" early 2011, Mountain Lion, but after reinstall i change it to snow leo) got blue screen every i normally booted it. It enter the OS only when it's in safe boot.
I've tried any solution that i got from the internet, such as:
-Reinstalling the OS X (normal install & clean install)
-Reset PRAM and SMC
-Repair Disk Permissions and Repair Disk from Disk Utility (the result is OK. There's no problem)
-Repair Disk Permissions manually (with Command + S at the beginning of booting)
-Checking Hardware from Application Installer DVD (result is OK)
-Checking from Mac Resource Inspector/MRI (result OK)
-Booting from Recovery Disk is same problem, blue screen
All of that solution is not working. My Macbook still got light blue screen and sometimes blue screen with lines after apple logo and spinning wheel is shown.
HDD is in good condition because when it's checked on the other macbook it can be booted. But if you must know, other HDD can't be booted when its plugged to my macbook (blue screen again). If i do safe booting, it works but can't play video and music also photobooth. I got confused with this case.
Any solution or comment? Thank you very much by the way

Hi. I'm not trying to rush things, you may have a different problem, but your issue looks quite familiar to me. I recently had a problem with the discrete graphics card (the Radeon GPU) due to overheating, all because a faulty application of the thermal compound in the factory.
In my case, the problem started slowly and intermittently, a few days after a gaming session (Quake 3) of about three hours (at the moment, I didn't realized that could be linked to the problem).
This issue is being actively discussed in another threads in this forum, but so far there's enough evidence that it's been causing similar problems for 2011 MBPs owners: screen corruption, black/blue screens, and in some cases, a total inability to boot. Some of the threads I'm talking about:
https://discussions.apple.com/message/13150366#13150366
https://discussions.apple.com/message/21110132#21110132
So far, and since the problem seems to affect only the discrete GPU (that's why you can boot in safe mode) a possible solution is to disable it by removing some extensions which prevent OS X from loading the Radeon drivers. This post describing the process (there are different files involved depending of your GPU version, so make sure you are moving the right ones):
https://discussions.apple.com/message/22521574#22521574
In the case your discrete GPU survived and is not permanently damaged, I personally had success by changing the thermal compound myself, which completely fixed the problem (at least for now). I've posted about it here:
https://discussions.apple.com/message/22630561#22630561
I hope you can find a solution, believe me I know the feeling when you see your expensive machine turning into a brick and it *****.
Good luck!

MacBook Pro 15 early 2011 slower than it must be...!!!

Hello everybody,
I have an MacBook Pro 15 early 2011, 2.2 Ghz, 4 RAM... It is running Mavericks 10.9.5, the latest update... The Etrecheck statistics seems to be very fine. So, here are some good and interesting questions: Why does my Mac work not that fast as it was on Slow Leopard? Why do I wait around 25-30 seconds to run Microsoft Office Document? Why the operating system is booting around 60 seconds? Why when I use software like MatLab, it turns that is not so possible to switch between the apps really fast, because multitasking freezes?
At the beginning, when I installed Mavericks 10.4.1, I thought that it is not enough RAM, after I read some comments from people that are using 2009 MacBooks running Mavericks and everything is fine, I canceled this possibility. Then I thought that my HDD is dead, I checked it 1000 times, its fine... So, the question is: what could it be, slowing my mac???
I plan to increase my RAM to 16 GB, but I am really not sure if it will help, because mavericks has another algorithm of RAM usage...
Really hope to hear some logical answers!

Remove "MobileGo," or else refer to its developer for support.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

MacBook Pro 13" Late 2011, 16GB RAM and Apple Premium Service Center

Hello all,
My dad has a MacBook Pro 13" Late 2011, it came with a 4GB RAM. When he got Parallels and installed Windows 8, 4GB RAM were not enough to even deal with Safari so he had to buy 16GB RAM from Cruical. Today when he went to Apple Premium Service Center here in Qatar (51 East) they refused to install the x2 8GB RAM and only installed one of them. They kept warning my dad that installing the whole 16GB can cause issues with the MacBook Pro HDD and can make it go faulty. I wanted to ask if installing RAMs can pose the HDD life to any danger. Because my dad uses his Mac for work and wouldn't like to lose any of his files against small additional speed.
Thanks.

its very easy to do, here are step by step instructions with photos

How long is the Battery your Macbook Pro 15 Inch (2011)

I might get a Macbook Pro 15 Inch 2011 with the 256GB SSD and the High Resolution Screen!
How much Battery Life would I get?
1) Going on the Internet
2) Running Skype
3) Playing Flight Simulator
4) Running Word
OR just list how long your battery is on your Macbook Pro!
Thanks!!!
(Will the higher resolution display affect my battery life)?

I was saying all of those combined on the newest MBP
if you're just worried about word, depending on the version, it might not even run on the computer.
And surprising as it may be, web browsing, depending on how you browse and what plug-ins you have installed, can be a very intensive task that takes up CPU and memory.
I found a very good discussion specifically about your issue but the site is riddled with ads so just google "MBP battery life 2011" without the quotes for further information. (it's very vast)
Long story short, bring your power brick with you if you take your computer out. There are also extra battery options that are said to help you charge your computer however, the magsafe power adapter is Apple propietary hardware that no one is able to make unless it's an Apple branded product so these batteries usually have a three prong plug (depending on where you're from) to pluginto with your power brick.

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

you can upgrade to 16GB if you wish to do so...
average price for 8GB 1333MHz DDR3 is around $50 - $75 depending on the brand.
why not spend $100 and go with 16GB 1333MHz from Crucial or Corsair.
you can get them from Amazon.com or newegg.com
see image below with 16GB Patriot Mac Series 1333MHz for $100.

How Do I Transmit Audio from My 2008 MacBook Pro to My 2011 Samsung HDTV?

Hello,
I'm trying to transmit audio from my 2008 late model MacBook Pro to my 2011 Samsung HDTV. My MacBook's Model Identifier is MacBook Pro 4,1 (ancient, I know). I purchased this DVI to HDMI cable which does a beautiful job of transmitting the video to my HDTV, but no audio (as advertised): http://www.amazon.com/gp/product/B000E8SY5Q/ref=oh_o02_s01_i00_details HELP!!
Thanks very much.

I figured it out! I plugged in my 3.5MM auxillary cable I use to plug my iPhone into car stereo jacks from the headphones port on my MPB to the "PC/DVI Audio In" on the back of my Samsung HDTV and voila! It worked! No additional cables (other than these two). No upgrading OS. Yay!
Here's the auxillary cable: http://www.amazon.com/AUDIO-3-5MM-JACK-AUXILIARY-CABLE/dp/B002Q3K0QS/ref=sr_1_1? ie=UTF8&qid=1330576344&sr=8-1
This looks like a great workaround to the MPB to HDTV audio problem! Hopefully my geek status is still intact. W00T!
When in doubt, try all the cables you have in all the different ports. AV hasn't changed much over the years and you can often rig things to work with what you already have. Yay for keeping cables out of landfills and repurposing!

What is the max memory allowed on a macbook pro 15" (late 2011), and what speed is the max speed allowed?

Hello,
I own a Macbook Pro 15" (late 2011) and I would like to upgrade the memory. I want to go with two 8gb sticks but if the motherboard only supports 8gb then I will have to stick with 8gb. Also, the ram that I have in currently, which is the 4gb that came with the mac, is 1333 Mz. Would I be able to upgrade to 1600 Mz on this laptop?

Max is 16 GBs. Do not attempt to use memory with specs that differ from those required by your hardware.
Maximum Memory
16 GB (Actual) 8 GB (Apple)
Memory Slots
2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
