Chosen Solution
Hello, I have a big problem with my macbook pro so here I am. My laptop is a macbook pro 13" from 2010, model 7.1 with processor core 2 duo 2,4GHz. Under El Capitan. My laptop started to turn off overtime I unplug the charger. My battery is at 31% and the light on the charger is green instead of orange. If the laptop is off and the charger is not plugged in, it does not turn on. I tried the reset the SMC as recommended but the problem is still there. My app Battery Monitor tells me that my battery is not dead, as I expected it (I changed it only 2 years ago). Do you know what the problem can be and how can I fix it please ? Regards, Some girl in need on your help.
Let’s get a better look at the condition of that battery. Please download, install and run Coconut Battery and post your results: http://www.coconut-flavour.com/coconutba… UPDATE 8/17/17 This model is known to run hot but lets try removing the fan and cleaning the vent, here how to get it out: MacBook Pro 13" Unibody Mid 2010 Fan Replacement This failing, you need to examine the logic board around the heat sink looking to see if there is an oily residue. If present it indicates that the heat sink has leaked and needs to be replaced along with the thermal paste.
I have no previous experience in Macs, but all points the battery. Seems the battery it’s somewhere bad with the cells. Inside the battery are some smaller batteries, and when one of them is wrong, it discharges very fast, and it’s not providing the electricity the computer needs. The sensor detects that the bad cell is charged, and says its at 31%, but it will drain quick and it will be dead fast. You can search some software about the health of the battery (maybe can check each cell and tell which is bad)
Hi Chloé, I would also assume it is the battery that is faulty. If you take out the battery all together and just use the charger, does it work okay and stay powered on? If it does then I would say the battery is definitely the culprit. I had a battery in an old acer laptop and even at 99% charge as soon as the charger was removed it would power off. Also it doesn’t really matter when the battery was changed, it is very dependent on cells used, how frequently it is charged and if it is charged fully. You can buy a replacement battery on ebay, might be cheaper than going to a repair store. Good luck.
