• Battery no longer seems to be charging on 13" Macbook.
    14 replies, posted
Hey guys, having a little problem. I was using my Macbook a few weeks ago to do some work, and shut the lid to put it to sleep. However, I'd forgotten it was asleep and today was the first time I'd woken it since then, meaning it's been asleep for at least 2 weeks. Normally, leaving my Mac asleep for a day or two doesn't seem to be a problem, but now my battery wont charge, meaning I can't use my Mac without my charger. I was wondering if it was just the LEDS on the battery pack but the charge icon shows this message: [IMG]http://i.imgur.com/OLFY2.png[/IMG] Anyone got any ideas?
I think you'll be fine if you reset your PRAM. Hold the Command+Option+P+R keys simultaneously right after you turn it on. You should hear two chimes, then let go. [editline]18th February 2012[/editline] Also maybe reset the SMC: [url]http://support.apple.com/kb/HT3964[/url]
I tried resetting the PRAM but I'll give it another go. Haven't tried resetting the SMC, I'll give that a go as well. [editline]19th February 2012[/editline] Nope, neither method fixed it. Is it safe to say it's knackered?
I don't think so. Batteries don't just pop after 2 weeks of no usage. I haven't touched my laptop for over a month but I just reinstalled Windows on it and it still holds a charge, even though it's ~4 years old. For the time being see if you can use another charger or MagSafe cable and see if it isn't your charger that's the problem and not your battery. actually nevermind I remembered that it still powers the laptop I'll research around, hold on. For the actual time being go to About This Mac and post what it says about the battery.
What model is the machine? Is it one with a removable battery? (If so, did you pull this out when you reset the SMC?) Also, how old is it?
Here's battery info: Battery Information: Model Information: Serial Number: DP-ASMB016-378d-2d22 Manufacturer: DP Device name: ASMB016 Pack Lot Code: 0002 PCB Lot Code: 0000 Firmware Version: 0110 Hardware Revision: 0500 Cell Revision: 0102 Charge Information: Charge remaining (mAh): 0 Fully charged: No Charging: No Full charge capacity (mAh): 0 Health Information: Cycle count: 1304 Condition: Check Battery Battery Installed: Yes Amperage (mA): 0 Voltage (mV): 4752 It's a 13" Macbook and yes, I removed the battery when reseting the SMC. It's not terribly old, bought around December of 2007. [editline]19th February 2012[/editline] I also tried with a different Magsafe, didn't change anything.
Info says dead battery.
Your cycle count is 1304 (The amount of full discharges you've performed) and your full charge capacity is 0 (meaning it's unable to retain any charge). The battery has been consumed, so it needs to be [url=http://store.apple.com/us/product/MA561LL/A]replaced with this[/url]. It would be a paid replacement, as consumed batteries aren't defective - they've just ran out of life.
Okay, thanks for the help guys. Just need to find the money for a new battery.
Ah, yes. Turns out that it was the battery then. Glad I could help you find the problem :v:
If you haven't got a new battery yet, or hell even if you have, install Battery Update 1.4 from Apple's support site. It fixes an issue with batteries not charging after the MacBook being asleep/off for "extended periods of time". You can check if it's already been applied to your new battery by seeing if Pack Lot Code is 0003, not 0002 as you posted. I had to get a new battery a few months back and had tons of fun wondering why my 2 week old battery wouldn't charge after being turned off for about 3 days. And if you're on Snow Leopard or Lion, look up the Terminal commands to install the update, Apple fucked up and made it only work on Tiger and Leopard.

I'll have to find out more information since it's officially listed in a certain article and I can't remember it off the top of my head. I wouldn't be worried though, it sounds like the battery is running quite well.

I got to test it out because my work had a power outage yesterday haha
