MacBook Pro 2.0Ghz runs warm, battery life not bad?

The MacBook Pro 2.0Ghz runs warmer, battery life not too bad!!!! You have to love that packaging...

With Windows XP machines the CPU has three basic speed modes (with many other power saving features)
Full speed , in this case 2GHZ
low speed: 600MHZ or 800MHZ,
and 'dynamic' mode (throttles the cpu form around 100MHZ to 2GHZ on the fly according to demand).
So on a Windows machine you can set the cpu to run at 600MHZ constant which is good for heat issues ( and battery life)
Of course 'dynamic' mode also is good fo heat and the battery (nice to have options)
In practice these features work well and have been present in the mobile chips for quite a while now.

Macbook Pro crashes when running on battery

Hi.
My Macbook Pro crashes when running in battery. It seems it doesn't happen when connected to the power.
Is there any way to know if it's a battery malfunction?
Because Apple changed the motherboard a month ago or so because Nvidia broke. So it could be also the connector to the battery?
Is there any tests I can run?
Thanks

I would take it back to Apple and have them check it. You may have got a replacement logic board with a problem. Apple usually use rebuilt ones.

I have the 13" Late 2011 Macbook Pro, What are the best Battery Life saver/increaser Techniques?

Specs-
2.4 Ghz Intel Core i5
4GB 1333 MHz DDR3
intel HD 3000 384 MB
How can I prevent My battery from degrading or atleast make the degrading slower
Can Ya tell me the steps or things to do?
I use my Mac a lot, like 6-15 hours everyday.
Someone told me I should keep it plugged with decharging it fully once a week.
is it true?
Can anything else be done?

You can use it on battery almost full time. It will slowly discharge to about 95% on AC, but then recharge after dropping below 95%. This is to save the use of the recharge circuits.
You should use it on battery only down to 40% at least once per month. Running it to dead will shorten battery life, not help.
The battery is rated to 1000 cycles. Two recharges from 50% to full is 1 cycle, 3 recharges from 33% to 100% is 1 cycle, etc ...
If you plan to store it unused for 3 months, discharge the batery to 50%, then remove from the MBP to preent the battery going down to 0.

Macbook Pro 2012 10.8.2 battery life *****!

Good Afternoon Everyone.
This week I notice my macbook pro battery life run out of juice very quickly. Yesterday start it using it at evelenish at 50% at 12:30 was down to 7%. Today, well right now It was at 99% I'm 15 minutes into using battery down to 85%, why is my battery dying incredibly fast? Can I get tips on battery saving?
Thanks, Have a nice superbowl sunday everyone.

MacBook Pro Queries with Mavericks (Wifi & Battery Life)

Hello all !
I have a MacBook Pro (non Retina) purchased last month, running the latest installment of Mavericks. i7 Core processor, and 16GB of RAM.
Lately, I've been noticing two major issues with the computer that I can't quite diagnose - 1. Wifi Signal Loss, and 2. Battery Life Performance
1. Wifi Signal Loss- apparently this has been widespread since the introduction of Mavericks; while the recent update supposedly took care of the wifi signal issues, my laptop continues to suffer, sometimes randomly. Every other device stays connected constantly to the internet at home, so I know it's nothing to do with the router or house connections. The computer has an issue with waking from sleep with a wifi signal- it seems the only remedy is turning it off/back on. I've tried the PRAM and other computer resets, toggling the "Wake for Network Access" functions, creating a new settings group with Wifi signal preference over bluetooth (and BT is always off, by the way,) yet it seems to stall. Also, at times it just seems to stall. Only way to fix is turn off/back on the wifi access.
2. Battery Life- Seems I should be getting more performance from a MacBook Pro than <2 hours playing with iTunes and Firefox. The music is on an external hard drive, and I'm just adding files to the library while playing some songs.. however, shouldn't there be superior results? I'm skeptical at this point. If I decide to run more intensive programs, such as the Adobe Suites, what will become of its life away from power supply then?
Any assistance and insight is greatly appreciated!!

No one?
This is getting frustrating, as the battery drains so quickly if simply just web browsing. does the 16gb ram cause this?

MacBook Pro 15 inch mid 2009 Battery Life issue

Hopefully someone can give me some useful info on what to do!!
About 3 days ago I noticed that the battery status on my MacBook pro 15 mid 2009 changed to service battery.
I checked the system profiler and this is what I get:
Charge Information:
Charge remaining (mAh): 1430
Fully charged: Yes
Charging: No
Full charge capacity (mAh): 1430
Health Information:
Cycle count: 169
Condition: Check Battery
Battery Installed: Yes
Amperage (mA): -1130
Voltage (mV): 11895
I have tried resetting the SMC to no avail and have also done a battery calibration. Surely this is not normal.
Lastly, I have no extended applecare, and the 1 year warranty ran out about a month ago (yay!).

Hi Nick
That seems unusually low cycles for a failing battery - contact apple customer support, despite the warranty and/or the seller, depending on consumer law in Australia.
There was an apple mention of expected minimum battery life somewhere, - not sure if it applied to your model... hopefully someone'll recall the link.

I just got a brand new 13" Macbook pro with Lion and the battery life is terrible. i just got a brand new macbook pro 13in a few weeks ago and everything is fine except the battery life is terrible!

i have seen many other threads about this, but i just want to know if anyone has found a fix that actually works? or do i just need to wait for apple to send a fix in their next update?

Suppose you elaborate on what you are doing with the MBP that makes the battery life terrible.

HT4718 I have a new MACBOOK PRO and after running updates IPhoto does not work

After installing Iphoto 9.4.1 from the MACSTORE updates Iphot will not run. I downloaded (.4.1 again and tried to install but it says that the update must be done from the Mac store. But I do not show any updates when checking the mac store and do not know how to proceed. I just purchased the computer and set it up on Saturday. I transferred files from an older Macbook pro.

How well does the MacBook Pro 2.0Ghz run games?

I am quite interetested because from the looks of the specs, it doesn't have the 'muscle' that you would see in a PC. Does it not need the high clocking speeds and memory that a PC needs? I pay quite a few game, mostly FPS and though I have a PC as my main gaming machine, I am wondering if this will be able to play games fluently. Games include (for both PC and Apple) Counter-Strike: Source, America's Army, Battle Field 1942, etc. Sorry if this seems... off.. but I am new to the Apple way.

Macs until this January ran on PowerPC CPUs, but the switch is on to bring them all into the "Intel inside" world. Apple realized this transition would be very hard for software vendors who would have to recode their products for the new CPUs so they basically bought a company called Transitive for its translation technology, which Apple calls Rosetta.
Under Rosetta PowerPC code is translated to Intel code. This means there is considerable overhead on startup and when new code is needed by the application during use, but it's much faster than emulation which is basically a virtual hardware machine made out of software within the OS - pretty technical, and not fast.
Anyway what you need to know is that PowerPC programs, the vast majority of them, run just fine under Rosetta, but at somewhat of a performance penalty. In something like a text editor this would be almost undetectable, but in a 3D FPS it could really drag down frame rates and overall performance.
The answer is Universal Binaries: programs that are compiled to run natively on both Intel and PowerPC. More and more are released every day. UT2004 patch 3369-3 (I believe it is) is a good example; it's over 100MBs but contains code for both PowerPC and Intel Macs, making the game "hardware agnostic" and giving you great performance on either CPU.
Hope this explains it.

MacBook Pro 13 2010 running Mountain Lion: will not boot and shows a folder with a flashing question mark. Will not start in 'safe mode' i.e holding shift on start up - nor can I call up any utilities with the OSX shortcuts. Any thoughts?

Following an automatic update, the machine wouldn't boot. Screen came on (shows white) - then either showed a 'No-Entry' Sign and a spinning cog, or a folder with a qusetion mark. I tried to start the machine in different modes ( eg. holding shift after the tone ) but nothing worked. after leaving the machine alone for 1 hour. It worked perfectly again. I did a 'verify disk' check which found no problems. 2 hours later it then froze ( In - Photoshop). Could not force quit, so shut down, and have not been able to boot again since (white lit screen - flashing folder with question mark) . I have also taken the hard drive out and checked the connections which seem fine. Any suggestions? - Is the Hard Drive dead. : other info : It was also running parallels 8, with Windows 7. at the time of the update....

This article may help: A flashing question mark appears when you start your Mac.

MacBook Pro 2011 slow at low battery

I have an early 2011 MacBook Pro 13" and when the battery gets to around 15% all applications seem to slow down. After about a minute of being plugged in everything runs smoothly again. Is this normal? Is it just trying to save power by slowing down processors?

I should have been more explicit. My intent was not to suggest the the MBP should be connected to the AC outlet 100% of the time. If conditions permit, use the AC connection, if not use it under battery power. If you have had the MBP connected to the AC outlet for 4-6 weeks, then do disconnect it and run it with battery power to a 30% - 40% discharge level and the proceed with a charge back up to 100%.
All batteries deteriorate and discharge over the course of time regardless of whether they are being used or not. Chronological maximum battery life will be achieved by minimal to moderate battery usage. I have a replaceable battery in my old MBP that is about 4 years old and is and is a 91% health. The newer MBP has the original battery and in 19 months of usage is at 96% health. I may not achieve the number of cycles that Apple advertises, but I am confident that I will get at least 5+ years service from them.
Certainly there may be situations where an AC connection is not readily available and the cycle count will accumulate quickly and the battery life will be shortened as a consequence. (ex. a student in classroom environment) Such situations are the reason why we have battery powered MBPs, but if you discharge a battery totally every day, it will need to be replaced well within three years of service.

HT1338 my macbook pro has been running hot off and on

My macbook pro has been running hot off and on for the last couple of days

Are you running andy anti-virus or "cleaning" software? Both can shorten battery life and run up the temps.
Take a look at this Apple article:
Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
Note in Step 3 you need to make a change if running Mavericks. In Mav, Activity Monitor's "Show All Processes" function moved from the application window to the application menubar:
Setting to "All Processes" is the only sure way to catch some suspects. Not noted in the article is this: AM won't tell you much if you run it shortly after a restart. Use your computer as normally as possible for at least a half-day before running the test. Also not clear is that you should be looking for any process that uses more than about 10 percent of the cycles. I've checked a lot of Macs with AM and, assuming you quit any user applications you started (other than AM) nothing should be a percentage larger than a single digit in a healthy Mac.

MacBook Pro mid 2010 13 inch battery?

Hello,
I remember my old MacBook's (white, early 2008) the battery showed things like : "Replace soon" and so, but on my MacBook Pro it went to Service Battery immediately.
Now it seems it still holds as much as charge as it did before, so I don't know if I should replace it. First I'll try calibration. I already reset pram and everything… Shouldn't the cycles be up to 1000 at least? This is why I bought this MacBook at first place.
According to Mac notebooks: Determining battery cycle count it is 1000 cycles, but I've only charged it 420 times.
What can I do to improve my battery's life and why isn't it 1000 cycles as Apple promised? I have a feeling I will never buy any Apple products again if I have to say goodbye to my battery soon. Disappointment after disappointment ;( Hopefully it can be still saved without a replacement.

It's quite important to remember that the lawyers added two wiggle words to convert a tech parameter into Legalize (my emphasis in bold italics):
The built-in battery of your MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles
[from http://www.apple.com/batteries/notebooks.html under the section, "Your New Notebook"]
That means they don't HAVE to replace a battery that signaled "Service battery" but is otherwise not showing signs of failure like leakage or short runtime.
ToWhite-1: Were it I and I were getting reasonable runtime, I'd be inclined to ignore that warning for the time being and simply watch for sudden changes or a catastrophic drop in runtime.
