For those having battery issues:

I had an issue with my battery a few weeks ago.

It went from 3 - 4 hours of battery life on Tuesday to 30 minutes of battery life on Thursday. The battery health also went from "Good" to "Poor" a few days later. I took it to the Apple store where they replaced it free of charge (hassle free, as well)

Be sure to check your system profile (Apple --> About This Mac --> More Info...) under "Power" to get more info about your battery (Battery Information). It shows your Battery Health, as well as other info like charge capacity and remaining charge. "Good" batteries will have a charge capacity around 4000 - 6000 mAh. If your MacBook is relatively new and it's hovering around 1000 - 2000, you need to recalibrate your battery.

Here's instructions on recalibrating: http://docs.info.apple.com/article.html?pa.../en/mh2339.html

I've posted in this thread about a month ago...I am still having the same problem.
Here was my last post describing my problem:

My mac runs out of batteries very fast, in a very abnormal way. I have the black 13-inch macbook 2.4GHz Intel Core 2 Duo
with 2GB memory and 250GB hard drive. I would charge it the whole night, and then use it the morning for about 20 minutes, and it would just turn off and wouldn't work unless it's plugged in. The battery percentage would go from 100% to just 7% after barely 20 minutes; it used to last about 6-8 hours.

My MacBook is relatively new and the charge capacity is 538 and the remaining capacity is 515, I tried recalibrating but nothing seems to work!
Now my MacBook won't work unless it's connected!! Should I just buy a new battery now?

^How long have had your MacBook? Maybe you can get it looked at by a "genius" and get it fixed free with warranty? O_O

What's your battery cycle and battery health? (You can find in About this Mac --> More Info --> Power)

Plus, you've recalibrated your battery, right? That involves:
1. Charging the battery until it's fully charged and then letting it "rest" for 2 hours (still plugged in) -- you can use your MB
2. Use your MacBook until the battery dies. Do not put it to sleep or shut it off. You want it to Power Off on its own...
3. Let it "sleep" for 5 hours - do not plug in the power cord at this time.
4. After 5 hours, you can plug in your power cord and charge up.

Also, have you tried resetting your power management (or System Management Controller). Here's the apple doc:
http://docs.info.apple.com/article.html?artnum=303319

To reset SMC, turn your computer off. Disconnect AC and remove battery. Press and hold the Power button for 5 seconds. Reconnect the battery and AC adapter.

If neither of those help, and your System Profiler shows your battery health as "POOR", you probably need a replacement...

Good luck!!

to anyone with a white macbook, how do you keep them clean? i just had my keyboard bit replaced and already it's starting to look gross.

[Millou]

i didn't know there's a topic just for Mac users...

well, i have a 17" iMac, and every time i want to put it to sleep it just shut down. I already have my iMac for 3-4 years and the first 2 years it worked perfectly, when i put it to sleep, or when i don't use it for 20min it will put itself to sleep. But now when i do that it automaticly shuts down...

doesn anyone know what the problem is?

i was worry about the same thing and my friend told me about a clear keyboard cover a couple weeks ago. i just order one hopefully i'll get it soon & test it out.

Anyone uses multiply here?

coz for the past 1-2 months, i'm having trouble viewing pictures in multiply. For example, whenever i click a picture to view it, it just wouldn't show up. The only way i can view pictures is when i click the slideshow button. It wasn't like that before, but does it have to do with the settings in my macbook? I've tried to view the pictures using a pc and a mac in my school, and it worked just fine.

Yeah, I use it. You might want to try using Firefox, if you are using Firefox, use Safari.

See if any of them displays the picture.

When I had to bring in my mac to the genius bar several times the guy told me
if you buy the mr. clean magic eraser it works just fine! I sometimes even use cleaning
wipes sometimes

no real graphics card, so I can't play 3d games. That's about it.

I find that almost all programs I've encouter that work on a PC work just as well on a Mac (as there's a mac version out there)

the same thing happened to me but on my powerbook which i've had for 3 years...i did some research and found out some of the batteries were 'defected'? anyways, on the apple site there is a page were you can check if your battery was manufactured during that time, you then enter in your serial number and they ship you a brand new battery. you do have to send yours to apple though but they do pay for all the shipping.

Or maybe just use your applecare and get it checked out

I'm planning on buying the MacBook Pro 17" black one, or either MacBook 13"; both which will be upgraded with a 4GB RAM, which one should i get as im planning on using it for uni when i start my architecture degree, and i know im going to mainly use it towards design programs; which requires it to be v.fast especially for 3D modelling and CAD work.

also does anyone know if it comes with an international warranty? or is it just a local warranty? as im planning on buying it in hong kong but i will be using it back here in London, UK.

^There is no such thing as a black MacBook Pro - they only come in silver.

OMG when you said Black MacBook Pro I jumped over to the apple store thinking I missed out on a new update. then I was disappointed when I saw nothing

Anyways, you want the Pro for 3D work. MacBook can't handle 3D well.

^There is no such thing as a black MacBook Pro - they only come in silver.

I'm pretty sure she ment Macbook Pro or Black Macbook now. *cries* no black macbook pro *sniff*

Woo! I got a macbook yesterday and i'm loving it! I got a student deal 10% off and a free ipod (well after the $200 rebate).

Anyways I got some newbie questions...

So i want to partition my startup disk because I don't think i'll be getting any extra mem anytime soon.. I'd also eventually want to work with windows as well .. How many partitions and how big do you recommend (I have a 160gb hdd atm)? I was looking around in the disk utilities and in the partition section and what does the different formats for the partition mean? (eg. Mac OS Extended Journaled etc etc..)

Thanks in advance 8]~

[erure]

I'm using the newest 15" MBP and there's something wrong with my external hard disk drive... Whenever I connect it to my computer, a message comes up that the drive cannot be read... Does this mean I have to format the disk? I have 400gb worth of stuff in there and I really don't want to lose it

I wanted to look at a GIF and when I clicked on it, the preview thing showed up. But it just had many images rather than the moving gif image.

I'm new with the MAC so can someone help me out or just tell me a software I can download to view images and stuff.
