Year Old MBP - Battery only Good for Two Hours

When I fully charge the battery over night and switch the battery indicator to time the most I get is two hours. Percentage view quickly shows from 100% for a few mins to 75% a few mins later and the most I can get out of it is roughly two hours. Based on these readings do you think the battery is defective?

Well, your battery's original capacity was about 4600mAh, and it still has 96% of that: very good for a year old. So it's there, but something is consuming it. Open Activity Monitor and use it to determine what's using the most CPU cycles. If you're using your machine in a brightly lit setting, make sure your display and keyboard brightness aren't being cranked up automatically: the display in particular is a huge energy consumer. If the Web sites you frequent are video sites like YouTube and Hulu that use a lot of Flash, that will eat up your battery very quickly.

2 year old MBP battery says replace now

Although my MacBook Pro ("15) is only 2 years old, it says that the battery needs to be replaced. It doesn't start when it's not connected to the current and if it's adapted it says: not loading. It's supposed to last 5 years...

Welcome to Apple Discussions!
Your battery could have failed prematurely. Report it to Apple and see if you can get a replacement.
BTW, 88 cycles are not very many for 2 years of use--batteries will fail sooner if they are not used enough. Here's a good read on batteries:
http://discussions.apple.com/thread.jspa?threadID=1764220
Good luck!

Battery on 24% for two hours with heavy usage.

This has never happened before. My battery was draining quicker than normal today and as soon as it hit 24% it stopped going down. It's been on 24% for about two hours now with heavy usage on 3g (lots of internet, lots of texting).
Any ideas what's going on?

Sounds like *+yet another+* calibration issue. I had one too today, battery was on 77% - then after half an hour of sitting idle it was on 62%! I watched half an episode of +The West Wing+ and it stayed at 62% which is unheard of, video usually drains the battery quite badly - I have since had to plug it in to sync and within about 10 minutes its on 79%.
It's probably not a faulty battery, it's just that the status display meter is giving the wrong reading. I expect you'll get the same number of hours from the battery as usual, and the next time you completely empty and recharge the battery it will recalibrate itself.

Limited Financial User licenses are only good for two weeks

I have repeatedly requested a license for a client who, according to their contractual info, both in my records and on the SAP B1 Portal 'Contractual Information' link, has
3 Professional Users and 3 Limited Financial Users.
Every time I get a license it is for 6 Professional Users, and it expires in 2 weeks because, so it says, I have exceeded my contractual license limitations.
I have been working with SAP Support but so far I do not have a fix. With Support, we have repeatedly deleted all previous systems for the client (both as Partner and as Customer S number), created one and only one new system, and submitted the request for 3 Professional Users and 3 Limited Financial Users.
And it still comes back with 6 Pros that expire in 2 weeks. I know that for now a Pro User is substituted 1 for 1 for the new limited license types, but why can't I get a permanent vs. a temporary 2 week license?
Please do not write and tell me how to delete a system or how to apply for a license, etc. I know how to do those things and I have walked through the entire process with SAP Support with me via Webex, and we don't get a permanent license. I just want to know if anybody has successfully got a standard license for the new limited types so I know that the process actually works. (Based on my experience, I don't think the Portal can handle the new license types. ) Then maybe Support and I can focus on a flaw in the contractual info as stored on the site, etc. as the source of my problem.

Hi Cindy ,
This is not a normal case. I have a lots of clients who are using limited license and their license are not expired .
Might be something happening with SAP recently because I haven't requested any license recently .
I had faced this issue one time when I didn't realise the date of expiration while ordering SAP license but I made correction and import it next time and it worked for me fine .
I am not sure how can i be of help but this certainly bring my attention and would definely like to know the solution
Thank you

My ipod touch 4th gen battery only lasts for 3 hours with wifi and brightness fully down

My ipod touch 4th gen battery life if asful only lasts a maxium of 3 hours with wifi turned off and brightness fully down any suggestions?

You can try restoring the iPod. However, it could be that the battery is going bad.
Apple will exchange your iPod for a refurbished onewith a new battery for $79. They do not fix yours.

A third-party place like the followingwill rplace it for less. Google for more.

IPhone 5 battery only lasts for 3 hours of usage

My iPhone 5 64GB is not working as well as I think it should be. After about 3 hours of usage (according to usage statistics in settings), which is just Facebook and web browsing, and 9 total hours of standby, the battery dies. This is mainly over 4G with medium brightness. Background App Refresh is off, most location services are off, Push emails are off, reduce motion is on. I have tried everything I have found online to try and fix this, but nothing has worked. On top of that, my iPhone was just replaced at an Apple Store, so I'm not really sure what it could be.
Any help is greatly appreciated!

Hello pierre0,
Thanks for using Apple Support Communities.
Since you have just received this iPhone as a replacement from an Apple Store, it should still be within its 90 day warranty. Please take the device back to the store and inform them of the issue.
A replacement part or Apple Product, including a user-installable part that has been installed in accordance with instructions provided by Apple, assumes the remaining term of the Warranty or ninety (90) days from the date of replacement or repair, whichever provides longer coverage for you.

X240 DO NOT HAVE Internal Battery, keypad backlit. 3 Cell External Battery only last for 2 hours!

Why does Lenovo dont tell about this missing features??
I bought the unit a day before I left the country, and then to my surprise it does not have the internal battery that Lenovo is boasting about. Fn+Spacebar doesnt work in lighting up the keypad and the 3-cell external batter is no way near to 4 hrs!
**bleep** hell Lenovo?
Another thing, is it possible to turn on the light (near the webcam) to light up the keyboard at all?

Hi,
1. Information about battery capacity for laptops with fixed configuration (i.e.not CTO) is provided in PSREF (for not all countries), on Lenovo support site in laptop model short description. It looks like the strings below:
6c Li-Ion
3c front battery and 3c rear battery
3c front battery and 6c rear battery
The 1st string is for 6 cell rear (external) battery.
If laptop is CTO the battery information is available in the purchase order or in the parts data base.
2. Keyboard backlight capability is optional feature. This information could be found in PSREF, in support site parts data base by laptop serial number.
3. ThinkLight feature is absent in Haswell based Lenovo Thinkpads.

Year-old nano's battery only lasts about 9 hours--normal?

The one-year warranty on my nano expires in about two weeks. The battery only lasts about 9 hours when playing AACs purchased from the iTunes Music Store continuously, with the EQ and backlight turned off.
Not too shabby, but also nowhere near the 14 hours it got when it was new.
My question for those of you who have had warranty repairs for battery problems--would Apple consider 9 hours of battery life "defective" and worthy of a warranty repair or replacement?
Any feedback or advice would be greatly appreciated.

Actually Apple says up to 14 hours. You're doing ok with this because you're getting about 65% or more battery life from the max of 14 hours.
Just to be clear, you can only buy the AppleCare plan during the first 12 months warranty period, so if your iPod is nearing a year old, better be quick.
Btw, have you seen these?

Hello
I bought my wife a new MacBook Pro, in setting it up for her, I took her Time Machine external drive to migrate onto the new machine but her old MBP not only was on 10.6, it was my old machine which I was still Administrator for.
i plugged in the external drive to start the migration process after entering her name and username from the old machine which gave me the options on transferring the old data over.
I also unchecked the Administrative end that had my info hoping that ONLY her data, files, etc., would be the ones sent over to her new machine which I wanted her to be the ONLY Administrator for. All went like clockwork until the restart.
Normally the screen should show the username and only need the password but both entries were blank, as in ‘Other’ sign in option available only. I entered her name and password, nothing….used her username and password, nothing. Used my old Administrator name and password, NOTHING!
I tried defaulting to factory settings from the Restore feature but it directs me to notify Apple. I tried in Terminal to change the password, nothing. I tried to boot from MY external drive and it doesn’t recognize it. I tried to even use my external drive which actually has the Mavericks upgrade, nothing!
Basically I can only get the startup screen which isn’t accepting the username/password or the Restore feature which doesn’t offer any options helpful!
Please, how do I start from scratch and start over here? Or simply change the Administrator name and password so I can proceed with everything thats already on there? I wish I could even boot from another drive but no luck on anything!

First, on the old machine, make your wife's account an admin one. Log into it and delete yours. Then, update the TM backup. Finally, use Internet recovery mode, ⌘⌥R, erase the HD, and restore the OS. One first boot, follow the steps outlined in Pondini's Setup New Mac guide.

I have a 5 year old MBP, 2GHz Intel Core Duo, 1GB MHz, DDR2 SDRAM, running Snow Leopard, 10.6.8.

I have a 5 year old MBP, 2GHz Intel Core Duo, 1GB MHz, DDR2 SDRAM, running Snow Leopard, 10.6.8.
I use wireless to connect to the Internet and everything works fine when I sign on. After being on line for awhile and my remaining battery power at about 60%, I lose connectivity. I turn off Airport, restart it, and I am asked for my secure password. I enter the password but cannot reconnect. So, I shut down the computer for 5 to 10 minutes, restart, and everything works great again.
Has anyone experienced this behavior and do you have any suggestions as to what is causing the problem.
Thanks for any help you can give me.
Lowell

I think I hit the wrong key ... so here it is again!
Thank you ... I keep seeing this i5 and i7 processor mentioned and it is also recommeded that I stream using it. Do you have any suggestions on which MacBook would serve me better? Or is there an upgrade of any kind that will help me?
Thanks again.

Battery only lasts for about 7 hours after Update to IOS 4.2.1

Hello folks,
after I have updated my Iphone 3G to the newest firmware (4.2.1) may battery only lasts for about 7hrs in standby-mode (no tethering, umts, wifi, whatsoever), while it has been much much better before.
Does anyone of you have the problem or a solution for it?
Thanks,
Alex

I'm happy to tell you that the problem, at least for myself, is gone. I checked around on the forum and apparently it could be so that something went wrong when updating to 4.2.1 so restoring the phone from itunes could be the fix. I did so and the problems seams to be solved.

This new update for the iphone has me troubled. Nowhere did I see where it was only good for 3GS,4S and or 5. Is this update also good for the 3GS? I'm reading people are haing trouble.

This new update for the iPhone has me troubled. Nowhere did I see where it was only good for 3GS,4S and or 5 or all. Is this update also good for the 3GS? I'm reading people are having trouble.

iOS 6 can be loaded without problem on the 3GS. Not all features are supported however.
With respect to your reading people are having trouble, what did you expect to see on this technical support forum? People don't write in to state they have a trouble-free upgrade.

Sales are restricted by country presumably because of licensing restrictions. In most cases those will be imposed by the distributors of the items. If a company has not worked out the license to sell a song in your country, or has simply decided not to bother, or in rare cases is prohibited by the government of a country, then Apple cannot sell it to you.

I broke my laptop last week and until I can afford a new one, I'd like to use my ipad for university. Just wondering whether there is a way I can view online lectures? I have an app called my media but its only good for direct download links

Only good for direct download links. I can pick to view my lecture in either audio or video format through WMP or QT from my school website. The formats come in a drop box form, which when on a desktop or laptop open in the player you choose and play. I hope this makes sense

You are asking several different questions. If you need to store your photos, music, and movies on an external volume, you certainly can. Any externally connected hard disk drive will work, connected either directly to your Mac or to your Time Capsule as a shared volume.
You should not rely upon using that as a backup device though. Although you certainly may use it for both purposes, it is a better idea to have dedicated backup devices for a variety of reasons not limited to redundancy. You would not want to simultaneously lose all your pictures as well as your backup. If they are all on the same device, that could happen. Furthermore, a backup cannot back up the volume on which it is running.
As for adding an Extreme or Express, using its LAN port for your iMac, and then enable Internet sharing so you can effectively use the iMac as a "hotspot", you can do that too, but I am unclear on what benefit you believe this arrangement would convey for you.
An Extreme's Guest network is separate from its Main network; that is the reason for having it.
