MacBook Battery Problems - A Variety of Problems with a Variety of Solutions
What are some of the common MacBook battery problems you may experience? Some people report their MacBook will shut off while it still shows plenty of power left in the battery charge. MacBook have a secondary power source inside that protects the onboard RAM. If this battery begins to fail, it will start shutting down the MacBook without giving an indication as to why. The MacBook battery status menu only shows the amount of power available in the main battery pack. If the secondary battery fails, the only real way to know if it is a problem is by trying to start up the MacBook on AC power without the main battery installed. If the computer shuts down, you have a secondary battery problem.
Another common one of the MacBook battery problems is unexpected battery drains. Sometimes a MacBook battery will show a healthy amount of power one day and then zero power the next. And you have not done anything to cause that drain. There a few things to do to make sure you have a battery problem and not anything else. The first thing is to make sure your power adapter is working properly. If the power adapter is working properly, you should see a green light on the connection from the adapter to the computer. This is showing that the battery is fully charged. If that light is not showing green or is not on, check a few other things.
Make sure that the power adapter has a plug into the wall. An unplugged power adapter means that the battery is not receiving the charge it requires. If the plug for the power adapter is in, make sure that it is in a good outlet. Outlets will go bad. Move the plug to another outlet that you know is working to see if that might be the problem. If the adapter is in a good outlet, you may need to make sure that the connection back to the battery is good. Check the connection cord between the adapter and the MacBook. If there are any frays or discolorations, you may have a connector problem.
MacBook battery problems are often not really battery problems. They may have causes in the peripherals. Make sure you are not running peripherals off your battery power. Some peripherals use your computer's power to run. If you are running off of battery power, they are running off the battery power. Taking those peripherals off can help retain your batteries charge.
