My 5 months Mac book battery go down soon. The battery should keep at least 8 hours. It became bad.

My new 5 months Mac Book battery go down really soon. The new battery should keep at least 8 hours. I don't know what happen to my new battery. Is there anyone have same problem as me? Please help me to solve this issue. I did still have the warranty. Just want to know if i have use my Mac book at right way. Thanks!

Have an Apple Store or an Apple Service Provider evaluate it since you still have a warranty. Once in a while a bad component will show up. Also consider getting Apple Care to extend the warranty to 3 years after purchase. You will never be sorry if you do this. Good Luck.

Mac Book Battery

My brother just bought a mac book pro and he read that you should always have your laptop plugged in. I feel that if you have a laptop you shouldn't always have it plugged in. He thinks that it helps the battery's health, but i disagree. What is right?

Keeping the MBP plugged in is not a bad thing as it will stop charging automatically. By not running the battery down, helps to keep the number of cycles down on the batt. There is a finite number of cycles before the battery will not hold a charge (around 1000 cycles is claimed but this can vary). Everytime that you run the battery to 50% that equals 1/2 cycle, or lower will equal a cycle when recharged. So minimizing the cycle count can help extend the battery life.
You can check the battery status by going to the Apple logo in the menu bar>about this mac>more info>system report>power in the left sidebar. There under batteri information you can see battery data.
I have a 2010 MBP with 62 cycles on it the battery works fine with normal power life when I run on it, but i usually have it plugged in to save cycles.
I will run it down to 20% every now and again then let if fully recharge. Have done this with multiple MBP's and have never had a battery issue, my kids 2006 batt is still fine.
Of course using on battery is not a problem, but I would suggest to plug it in when you can, to avoid un-necessary battery cycles.
Hope this helps

On average how long does your mac book battery last?

Mine runs about 1.75 hours on average while doing my best to conserve the battery. I would like to get an idea from other mac book owners how long their battery lasts, so I know if something is wrong with mine.
I know there are a number of factors that come in to play in terms of how long your battery will last. For instance, i know that if you have a lot of applications open, and if you have blue tooth device it will cause your computer to have to work harder and in essence will cause your battery to run out faster. It just seems like mine runs out real quick (1.75 hours). I have the check mark by "better energy savings" and close my applications as well.
I will also say that I did not calibrate my battery when i first got it being that this is my first laptop and i didnt know. I calibrated it about a month after i got it. However, prior to the calibration i had it hooked up directly from a power source all but one usage. Being that it took so long for me to calibrate my battery, is it permanently damaged?

A charge capacity of 4860, while being below average, is not a complete didaster and is not the cause of the 1.75 hour usage. Mosre than likely your failure to calibrate is the reason for it being below average. I does say to calibrate ASAP in the user manual that comes with your MacBook.
Now, to help with your battery time the things that affect the batery time the most are…
1) Processor performance. Make sure your Energy Saver setting are set for maximum battery savings.
2) High processor usage. The more you use you procossor the lower your battery times. So, you will get better battery performance when checking/writing e-mail and web surfing that you would encoding video. I often use a tool like MenuMeters…
http://www.versiontracker.com/dyn/moreinfo/macosx/17713
… to keep an eye on my processor usage.
3) Screen brightness. This is a huge battery user and you should set this as low as is comfortable. High battery times require the screen to be set to minimum values. One spot (minimum) is the norm.
4) Wireless networking. As this is always on it does chew up more battery that you would think. Turn it off when you don't need it. I actualy created a "no networking" profile in my Network System Preference for when I want to maximise battery performance and have no need of internet/networking.
5) Bluetooth. This also consumes quite a bit of power for something that is not used much. Turn it off as much as you can when on battery.

Mac book pro issue?

I've had issues with my Mac book pro that is about 3-4 years old. When I have ap age open and am scrolling down it wants to all on it's own go to the previous page when i have never clicked the back button. The other thing is I may have a couple of pages open and all of a suden one page will have this colored light thta is a round circle almost showing like it is loading the page and it sometimes freezes up. I always making sure my computer is up to date as far as software updates go but still has been acting up. I did once see on this computer it has like a virus blocker which is in the off position but I thought that apples can't get virus correct?? I'm just lost I don't know it can or does it have a virus or what.
Can someone please tell me what can I do to get these little weird qurks to stop happening??
Thanks
Chris

if i go to the top left hand corner and click the apple and go to system Preference ten I click on security it will say firewall on or off so I assume this is what protects the computer??
I know it's werid as ****, when i have a window up and I am scrolling up and down the page with the bar to the right of the page all of a sudden it is like some clicked the back button to go to the prvious page and I have never even clicked it.
The other thing is like when I click safari to load the page my curser instead of having the little arrow it will be a round abject with different colors likes it is trying to load the page but the page is wanting to freeze up and the curser doesn't move as freely as it normally should. Seems like this is getting worse seeing this. I don't know if this is do to the internet connection maybe??
Thanks
Chris

Mac Book power issues.

My Mac Book Pro will no longer power up. What is the likely problem?

Hello there Radar47,
If your MacBook Pro is still not turning on, I would recommend you use the troubleshooting information in the following article to help isolate and hopefully resolve the issue here, named:
Troubleshooting: My computer won't turn on
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

Mac Book Start Issue

My Mac Book no longer turns on, all I get is a blue screen and a folder appears on the screen with a question mark in it. Any ideas?

Try booting from your install disk by holding the C key down. Then when you get to the screen with a menu bar open Disk Utility and use it to repair permissions.
Your hard drive may have failed. You could also boot from your install disk while holding the D key down and run diagnostics on your MacBook.

Hello... mac book warranty issue

Hello,
I'm not sure whether i'm posting in the right page... hoping to get a response. I'd purchased a mac book pro 4 months ago in UAE. I reside in UAE as well. I got the 1 year international warranty with it but did not take the local warranty. My laptop has got damaged. I went to the apple care store and they told me my laptop is not under warranty. I'm assuming they are looking for a local warranty which i don't have. But my question is can they not fix my laptop under the international warranty that i have or will it only work if my laptop was damaged in any other country and had to be fixed there?
Thank you.

I would return to the store with your warranty documentation. No one here can speak for Apple as we are users just like you.

Mac Book Pro Issues

w,Hey there!
This is pretty Random, Im hoping someone can help me.
My mac is abouuutttt 3 years old... its had a good long life and up until 2 weeks ago was working perfectly.
My charger died about 2 weeks ago, I ordered one online and it arrived all good. Ever since I've plugged it back in my computer has sooooooo many issues that its never had before. First thing is its now saying the battery needs replacing. Now, i totally get that its old, i used to work in an apple store and have always been really really good about not leaving it plugged in etc so it doesn't die, before my charger broke it was getting at least 4-6 hours charge still. Now its barely making 2, and once i get to about 30% it just turns off. Not runs out of battery the computer just turns itself off. Because i can then go and turn it back on without plugging it in.
The second issue is that the date keeps going back to january 1994. It has NEVER done this before charger died, not once. Now every single time my computer turns back on i have to try and change the date and time back to today, Which is all well and good but System Preferences doesn't seem to want to open any more either... now i figure this is something to do with the date/time being all screwy but NO IDEA how to get it to stop doing this.
The third problem is the mouse pad thingie (can't remember what its called... Trackpad?) doesn't seem to click either.
As i said i get that its an old computer, But all ways been well looked after as i used to work for mac and as i said the day the charger stopped working is when i had all these issues. Can someone please help? Thank you!

Sooo If i just get the battery replaced then all the other issues will stop. Including the time date thing?

Mac Book Battery Question

If I have my charger plugged into my macbook pro 2011, but it is not plugged in to the wall(so it is not charging), will this make the batter of my mac drain faster?

Sorry, I am actually curious to the science behind this.......line loss
Been 15 years or more since I heard someone mention line loss.
In a lithium battery, deep discharges alter the chemistry of the anode to take up lithium ions and slowly damages the batteries capacity for the cathode to transport lithium ions to the anode when charging, thereby reducing max charge levels in mAh. In short, radical swings of power to lithium cells disrupts the chemical ecosystem of the battery to hold charges correctly which likewise impedes the perfect transfer of lithium ions both in charging and discharging. In charging your lithium battery, lithium ions are “pushed uphill” (hard) to the anode, and discharged “downhill” (easy) to the cathode when on battery power. Deep discharges, damages this “upward” electrolyte chemistry for the battery to maintain a healthy charge and discharge balance relative to its age and cycles.
From BASF: How Lithium Batteries work
https://www.youtube.com/watch?v=2PjyJhe7Q1g
Proper understanding of a battery charge cycle
A charge cycle means using all of the battery’s power, whether that is at once, or over several shorter battery discharges and recharges.
Two examples for clarification:
As a first example, where one fully charged battery is discharged down to 10%, then fully recharged, then using 10% of that full charge, this counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
In the second example, where one fully charged battery is discharged down to 40%, then fully recharged, then using 40% of that full charge, this also counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
While both examples are that of a single charge cycle, the first example is more aggressive against the lithium battery chemistry than is the second example. In short, collective overall gentle shallow or mid-range draining of your lithium battery is a better use condition than is the first example of deep-draining of the battery. While both are quantitatively identical as a single charging cycle, they are wholly different qualitatively on the battery chemistry, which is directly related to its ultimate longevity and health.
In short, it is the near and mid-term life of the battery as relates to its proper care (or lack thereof) that is to be looked after.
Priorities in order of decreasing importance for battery care are:
1. Avoiding deep discharges of the battery.
2. Avoiding having your battery constantly on charge or on charge and in sleep mode.
3. When playing graphics intense games, use your notebook plugged in when possible.
4. Reduction of battery cycles by plugging into power when on the go, or when accessible.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is vitally important on the wear and tear on your Macbook’s battery, much more so than is the counting of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will greatly hasten the lowering of maximum battery capacity.
Understand that a charge cycle is a general parameter of use, but is not directly related to the short-term or mid-term abuse of the battery, which can rapidly hasten a shorter lifespan, regardless of what the actual cycle count on the battery indicates.
Proper considerations for near-term care of the battery is of utmost importance. Abuse of the battery is entirely avoidable, long-term eventual old age deterioration of the battery is entirely unavoidable.
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less. Avoid this in all instances if you can. This is hard on your battery.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery).
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

Mac Book Battery Warranty?

I have a 2006 macbook with a battery that is not doing well. The battery stats are:
Full Charge Capacity (mAh): 2507
Remaining Capacity (mAh): 2499
Amperage (mA): 0
Voltage (mV): 12403
Cycle Count: 214
I went to the apple store yesterday and the genius said that batteries are only covered for one year, or 300 charges whichever comes first. Therefore despite having apple care I would have to buy a new battery on my own.
Is this true? Would I have better luck calling apple directly?
Thanks for your help!

As someone familiar with what they termed the 'review' process, I should caution you to be patient. Worldwide service personnel do not generally respond to such requests until two business days after they have been filed electronically, and situations which are not instantaneously and quickly correctible can actually take several days.
Has your issue been addressed yet according to that dealer contact?
Please understand that 'some fraction' of that $ 129.00 battery is typically $ 117.71 plus $ 6.95 in cost to a dealer. That's a substantial price for a dealer to pay, leaving hiim with a dilemma: he would have to sell nearly thirty additional batteries at that slim margin to make up the cost of giving one to you, when Apple refused to provide one at no cost to him on your behalf. That's a significant penalty to make you happy.
What you reasonably see as many thousands of dollars worth of purchases over time is actually very little in terms of what a dealer makes after costs of goods are subtracted, and before overhead is factored in. Your dealer is not trying to be the bad guy here - he is just trying to stay in business!

Mac Book Battery Not Detected

I just bought a replacment battery for my macbook. It was cheap from china, i knew it wasnt going to be a real one but why isnt it being ddetected by my mac?

sometimes batteries are dead on arrival. i would test the battery in a friend's computer to determine whether the problem is actually due to the battery or your actual computer. if the battery works in your friend's computer, then you know that your mac is having difficulty utilizing the battery.
i am actually experiencing the EXACT same problem with my girlfriend's macbook.

Ical iphone & mac book pro issues

Hi there,
I'm running a iPhone 4S with iOS 7.1.2 and Macbook Pro with Mavericks. I recently had to do a full restore on my phone and since then I'm having trouble syncing events between the two devices on iCal. I moved time zones recently too so that might be part of the issue. I changed the time zone to the correct one in iCloud and on my Macbook itself as well on the iPhone though for the last two I'm not sure if there are special iCal settings relating to that. I kept noticing a one hour difference between events on my phone and Mac so I experimented a bit with the time zone support category in iCal advanced settings on my Mac and on my iPhone but now it seems like if I post a new event on my Mac it simply appears as a blank new event on my phone and at the wrong time. If I post an event on my iPhone it will appear at the correct time on my Mac. I'm also noticing some of my events on my Mac stating the time zone while others are not. I scanned the forums but didn't find a solution yet so I hope these details help and that it's a quick fix. I'm not sure if I have to connect my iPhone to my Mac via USB and change some setting in iTunes. Help would be much appreciated! Thanks

I have no idea but for some reason it now seems to be fine. I didn't change anything at all so I'm not sure about the solution or what the problem was in the first place.

Mac Book screen issues

My Mac screen has started blacking out or if when im working ..screen and curser freeze and fades into screen saver..with ghost image of previous screen for about 30 seconds and then comes back and curser moves again..anyone else experience this issue? Had this Mac for 4 years with no issues..

By a clicking noise, do you mean sort of like a squeak?
