it was the main power wire to the fuse box
To maintain the clock while disconnected from power, computers have a small "button" battery located on the motherboard. You will need to replace this with a new one.
A battery is used to start a car. Once it is running, the alternator then supplies electrical energy to charge the battery as well as power the electrical systems in the car. Removing the battery while the car is running will not affect the running of the car.
If the battery is good and the starter is good, then you must have a wire disconnected somewhere.
some vehicles will reset to computer if you leave the battery disconnected for a while (sometimes 15-30min)
Normal power supplies are on all the time while switching type are on and off periodically which results in precise control and improved efficiency.
Engine Dies, but Runs for a while After Jump StartingIf you're sure the alternator is working properly, I suspect that you have a loose, or disconnected, connection of the conductor [wire] that is supposed to carry the alternator charging current to the battery, OR a battery that has become defective.
If your battery is dead and you connect the power supply with your battery installed, the battery will automatically start charging. If you wish to run your MacBook off your power supply only, simply remove your battery from your MacBook and connect the power supply. You will then be running solely on the power supply. If you battery becomes fully charged while your power supply is connected, you MacBook will switch to the power connector as it's power source - preserving the battery.
The battery.
Becasue the battery stores electrical power. You may get a shock from the battery if you short circuit it, or accidentally turn the laptop on while checking the power adapter. Alternatively, if you are checking to see if the power adapter is working, you will not be able to tell if the battery is in because it will be providing the power.
