Low Battery Notifier (MacBook Pro 2011)

Hi guys! I'm a new Mac user and am still trying to figure out few things about Mac OS. Anyways, i was wondering why my macbook pro doesn't notify me when the battery is low. I noticed it after I have nearly drained my battery life couple times already in the middle of working on something. I tried looking at the Energy Saver preference if there was a setting for that but there is none. Where shall I look? or Is there something wrong with my battery? I hope not.

Your battery probably needs to be calibrated:

No, unfortunately.
You have to use the proper power adopter.

Hello
I have a macbook pro 2011 13" that came with OS Lion (integrated not on a disk). I recently bought OS Mountain Lion of the app store and it is working fine. However I was a bit dissapointed in the battery so I decided to try and downgrade and completely failed, I froze the computer and when I restarted it it did not work. I went into recovery system and erased my disk and all that and went to re-download my OS. I was expecting to get the option to re-download Lion but instead I could only re-download Mountain Lion.
My question is since my computer originally came with Lion can I reset my computer so I get OS Lion back instead of OS Mountain Lion?
Thanks for any help. Any answer will be appreciated even if it is saying it is not possible.

Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
    1.    Select Disk Utility from the main menu and click on the Continue button.
    2.    After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
    3.    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    4.    Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Macbook pro 2011 battery question.

I got a macbook pro 2011, and I'm charging, draining and recharging the battery daily, i have the mac for almost 2 months and i have 75 cycles complete and the battery is on 92%, i want to know if I'm doing a good work charging the battery the way I'm doing it, or do i need to use another method, i work daily with this macbook pro in design, thanks in advance for the answer.

Honestly, I think you're cycling your battery a little too much. Apple recommends that you cycle your battery 2-3 times a week. So this means
2 months = 8 weeks
8 x 3 (cycles) = 24.
You should have roughly 24 cycles for the duration that you've had the computer, 75 is a little much for 2 months, don't you think?
I would strongly suggest cycling the battery only 2-3 times a week. Also, only do a FULL discharge every month. You should make the change NOW before you permanently damage your battery. I have the 2.3 2011 Hi res 15 inch MBP.

MacBook Pro 2011 - 15" Core i7 - SSD - Heating, Screen Flickering Issues

Hello,
I recently brought MacBook Pro 2011 15" Anti-glare High Resolution with Core i7 2.2 G Hz, SSD, 8GB of RAM. I installed Microsoft Office and Angry Birds at this time. I'm facing multiple issues with my first Mac. Is anyone facing these kinds of issues in new MacBook Pro 15" models?
Issue 1: Heating: Fan running on high speed even though room temp is below 60F. No major applications are running at that time expect Office 2011 and web surfing (NOT watching any video) and listening iTunes.
Issue 2: When I log-off from computer, the screen flickers and goes to lower resolution. Also the windows colors changed to different colors. After log-in, I went to System Preferences > Displays. The highest resolution is already selected (1680 x 1050) When I try to change to lower, it changes but still displays different window colors and changing suddenly.
Troubleshooting Steps:
1.) Shutdown and Disconnected Power Cable (at that time battery is at 65%)
2.) Reconnected Power Cable and Power On the system
3.) Display shows correctly.
Unable to Resolve:
1.) Still fan is running on higher speed at low temp (below 60F with no major application running)
2.) Sometimes Display is not showing properly. It shows different color shades.
I scheduled support call with Apple Support and let's see what Apple can do...

I brought my first MacBook Pro 2011 on Day 1, so I can't return it since it won't come under 14 day return policy. I'm taking my Mac to Apple Store to fix all these issues. AppleInsider is also confirmed Disaplay Flicker issue on some of the models that they tested.

Macbook pro 2011 maximum plug in time

I just got a new macbook pro 2011 and within a within a week I already have 9 charge cycles. The way I've been using it everyday, I'll charge it to 100% and then take it off, let it go down to 30-50%, and plug it back in till 100%. Using it like this everyday for a week has given me 9 charge cycles and I realize its bad because you need 1-2 a week.
-So is it better for me to leave it plugged in for 3-5 days straight and then take it off the power.. let it go down to 50%.. and then back to 100?
-What is the maximum amount of time that I can leave it plugged in continuously if I want 1-2 charge cycles per week - I feel apple's suggestion of not leaving it plugged in "all the time" is unclear on what "all the time" really is.

I realize that article says not to run on AC power all the time. But what exactly is all the time?
All the time is ALL the time. If you plug your computer into AC power and leave it plugged in for six months, you'll permanently damage the battery. Leave it plugged in for a year and the battery may be dead and impossible to charge. A notebook computer is not a desktop computer — its battery needs to be used at least a little on a regular basis.
If you never need to use the battery at all, Apple says you should calibrate it (see link in the article you've already read) a minimum of every month to keep the battery in usable condition.
If you never need the battery, why should you care whether or not it's in usable condition? Three reasons: 1) if the AC power goes out while you're working, the battery will instantly take over and prevent any of your unsaved work from being lost; 2) if the battery is dead, your processors will run at lower speeds; and 3) a good battery will enhance the resale value of the machine if and when the time comes to sell it.

Macbook Pro 2011 charging behaving weird. Charges and stops repeatedly and takes very long. Help?

So a few weeks ago my MacBook Pro 2011 started having charging problems. I would use it normally. Then plug it in to charge anywhere between 5-20 percent like I've been doing for the past year that I've had it (since August 2011). Anyway, what happens now is that it charges but extremely slowly - at least 4 hours to fully charge as opposed to the 1 1/2 to 2 hours that it used to take. Also, it seems to be draining a lot quicker than it used to while only browsing the internet. Furthermore, while charging, the battery meter goes from the percent its charged to to "not charging" back and forth. What's going on? Is there a problem with my battery, my computer, or the magsafe charger? [please refer to the pictures below to get a better understanding of my problem - these pictures were taken over a 2 hour time period - a time period that usually is enough to charge my computer] - if you'll notice, in the first two pictures, the percent barely went up by 10 in a half hour period:

Does anyone have any idea what the problem may be?
Thank you,

try doing a SMC RESET and see if that sorts it out for you.
if doesn't work - better take it to Apple and have them look at it before something else goes wrong...
good luck - hope you get it sorted out..

Late Macbook Pro 2011 won't charge via MagSafe adapter.

My friends Macbook Pro 2011 same as mine wont charge the battery via MagSafe adapter. The battery is good and the adapter also, ive checked them on my Mac. The problem is that on her Mac it won't charge. I've change the MagSafe adapter on her computer and it didn't work still no charge, no green light on the L shaped adapter. Can it be the Logic Board?

Resetting SMC could solve the problem.

Is it ok to turn off my macbook pro 2011

I would like to know if its ok to turn off my macbook pro 2011 every time its not in use , and its not connect to a power source .

It's ok to turn off your macbook if you're not using it for a period of time. Just make sure the battery is not fully discharged when you do so.
I turn my off when i know i won't be using it for the day.
You can however, just close your lid if you plan on using your macbook a few hours later.

Unusual shutoff on Macbook Pro 2011 while sleeping

My 13" Macbook Pro 2011 will be fully charged and will go to sleep normally. However, I will go about my day and 4 hours later I won't be able to turn my computer on unless I have it connected to the power adapter. Then when I turn on my computer, the battery life percentage is 0%. Why is this?
Isn't the battery supposed to last at least a day or so while in sleep mode?

Your hard drive will last a while longer if you keep the moving to the minimum when it is on, but on short term there aren't any problems. I have never even tried not to move my MacBook when the drive's spinning, and it still works fine after 2 years.
Of course, if you would have an SSD, move the thing as much as you want. Since they don't move on themselves, they can be moved freely.

MacBook Pro 2011 Repair Extension Program for Video Issues -Feedback?

Anybody have any feedback from the MacBook Pro 2011 Repair Extension Program for Video Issues?
I had my early 2011 15 inch 8,2 repaired (free) under the extension program. The machine now appears to run well - but much hotter than before. The case is significantly hotter - especially at the GPU corner and the fans are constantly on moderate to high (not full). Anybody else experiencing similar changes?

USB ports are still dead on MacBook Pro 2011

I am still out here. I have spent days weeks working on getting my two USB ports to work. I basically use the USB ports for a wireless mouse and various flashdrives/memory sticks. I have a MacBook Pro 2011 Snow Leopard 10.6.8 I have tried software update, SMC and PRAM resets, battery reset, hardware test, creating a new user account....and browsing and reading numerous discussion boards.....awgh! I have stopped short of using my install DVD (fear of loosing data), upgrading to Lion or Mountain Lion (some fear of loosing an application that might not be compatible), contacting an Apple Store (AppleCare or whatever--live 2 hours away + fear of expense), and of course, trashing the laptop. Does anyone out there have any possible solutions? I see I am not alone. --A frustrated first-time Apple products owner.

franklinstahl & PhilippsXS,
The reason Apple's choice of a forum for tech support is so frustrating, is that people like yourselves, who have obviously found a solution to their problems, never come back and finish what they started.
franklinstahl you posted this 6 months ago. I don't believe you've gone for 6 mos without working USB ports. PhilippsXS, same thing. Only a month has gone by but you posted about it twice then never came back.
Please tell the community what you had to do to fix your USB ports.
I just read that on the MBP unibody models, sometimes you need to remove the battery before resetting the SMC. I'm about to try that unless you report back first.
After I try it I'll be sure to come back and report on what happened.
GL
The other reason Apple support is so frustrating is that you have Level 5 members helping people but not revealing sources or how they came up with the solution as if it were magic.
You also have Level 5s like OGLETHORPE who don't have an answer but waste space and intimidate newbies by leaving sarcastic answers and unfounded projections in places that would best be left empty.

Apple MacBook Pro 2011 (10.9.2) - Keyboard behaving very oddly.

Apple MacBook Pro 2011 (10.9.2). My keyboard has started behaving strangely.When you press the certain keys you see other characters as well, such as;
1 - volume up
2 - `
3 - §
4 - ]
5 - [
6 - =
8 - right arrow
9 - up arrow
= - 6
up arrow - 9
right arrow - 8
I’ve tried resetting the NVRAM / PRAM.
Can anyone offer any other suggestions please?

Do you have a secondary keyboard you could connect. If that works properly, the other is probably faulty.
Try re-setting the SMC.

I don't have this machine but could it be a matter of adjusting the settings of upper or lower case.
