MacBook suddenly turns off at 40% of battery charge and trackpad doesn't work
Hello,
I had to replace the battery of my white MacBook (13 inches, mid 2010), because it was swollen, and the capacity was about just 20-30% of its original one. I bought a new one. Specifically, this one. After replacing it, I have those problems:
When I run on battery, the computer suddenly turns off at about 40% of the charge. No warnings. Just turns off.
The trackpad is not working properly. I can move the mouse, but I can not click. The swollen battery was pusing the trackpad, and I guess it's broken now. I don't know if I can replace it.
Coconut battery tells that the maximum charge of the battery is below the design capacity. Not sure if this is a problem, or Coconut battery is just comparing my battery's numbers with the theoretical numbers of a brand new battery. Check a screenshot
The battery drains too fast. From 100% to 65% in about 20 mins. So, at the end, I have less than 1 hour of battery time.
I've tried resetting the SMC, following these instructions. Specifically, pressing (left side)Shift-Control-Option keys and the power button at the same time, releasing all the keys and then pressing power button to turn on the computer. Not worked. I think it was even worse.
Could it be a problem of this specific battery? Or maybe just the MacBook doesn't accept batteries like that one? It's not original.
In the first case, I would return the battery to get my money back. In the second case, I guess I should have bought an original one.
Additional data that may be useful:
Mac OS X 10.8.5 (12F4S)
EFI boot ROM version: MB71.0039.B0E
SMC version: 1.60f6
About EFI boot and SMC versions, those are the last available official updates, obtained from here.
Many thanks in advance.
I'd say it was a faulty battery.

My MacBook suddenly turned off. And won't turn on
My MacBook suddenly turned off. There was a click sound and then nothing. I have tried to restart it but nothing happens. No sound no lights. It is plugged in and the power cord shows green. I have not damaged it in any way.....
Here is what to do;
1. Unplug everything from your computer.
2. Take off the bottom of your MacBook / Pro / Air. (There are usually 3 screws that are longer than the rest near the vent, remember where they go.)
3. Carefully unplug the battery from the logic board.
4. Wait 10 seconds.
5. Plug the battery back into the logic board.
6. Put the bottom cover back on.
7. Reboot the computer holding the "Option" key.

Try a
Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data -

If a reset doesnt fix it (which it wont - that is likely a hardware issue), then get warranty service.

Sudden turn off and loss of battery
I was working when all of a sudden my MacBook suddenly turned off. I got it to turn back on but it said no battery detected and when I plugged it in there was nothing saying that it was charging. Also now when it is turned on the fan seems noisier than it was before. I've tried different outlets to see if that was the problem but so far nothing. It is still turning on, bur with the problems I mentioned. If anybody knows what is going on it would be greatly appreciated if you could let me know. Thank you!
Try a SMC reset, select the link for a removable battery or a battery you should not remove yourself.

My iphone4 turned off with plenty of battery
my iphone4 suddenly turned off with plenty of battery. and my on/off button does not work for me to reset it.
your battery meter is wrong. im running into the same issue without ryhme or reason. my phone was shutting off at 52% like clock work, then it moved to 58%, then finally after being off for half a hour i plugged it in one day and it actually showed 1%. problem fixed.
yet then a week or so later, it shut off on me at 35% and seems to be back to normal again.
the only way i've seemed to fix this is to use the charger that came with the phone or my ipad and have it plugged into the wall and let it say 100% for about a hour past it turning to 100. then when i unplugg it i do a shut down and restart, then i do a hard restart by holding in the 2 buttons until the phone starts to boot up again.
im on a verizon 4s 16g btw. this has been going on for about a month on mine, and just this past weekend my contacts started coming in as just numberes, no names, even if i text someone thru my contacts, the text back to me will come in as a new text under the number and not thier name. again, just randomly fixes it self after soem restarts and reproggraming by calling the verizon number.
lot of frustrations for a 4thgen phone from a company. -

Hi i'm sorry but what is SMC?
System Management Controller
The System Management Controller (SMC) is responsible for many low-level functions on Intel-based Macs. These functions include:
Responding to presses of the power button
Responding to display lid opening and closing on portable Macs
Battery management
Thermal management
The SMS (Sudden Motion Sensor)
Ambient light sensing
Keyboard backlighting
Status Indicator Light (SIL) management
Battery status indicator lights
Selecting an external (instead of internal) video source for some iMac displays
You didn't click the link to Apple's instructions and explanation, why?
Here it is again, click, read, follow the links for your machine and the instructions how to perform or take your machine in for service.

My 2 year old 13" MacbookPro suddenly turned off, presumably when the screen automatically dimmed (or went to sleep?) and now it won't turn back on. It was at 96% charge and now when I use the battery checker on the side, nothing shows up. No lights or anything. The charger doesn't seem to work either even after trying it on different outlets. This has never happened before but it has been harder to wake it from sleep in the last 6 months or so. I would have to push the On/Off button for a sec and the screen would turn back on. Also when I turn it on, the password screen is sometimes off-centered..weird.
I'm using Yosemite, the latest version..not sure what it is and can't check right now...I had to go use a PC to ask this question >_<Try a SMC reset:
