In normal times, if the computer is not used for a long time, the battery will enter a dormant state, and the machine cannot be started. I believe you often encounter this situation in your life. If your company has a computer, your laptop will not be used for a long time. Today, let's introduce the method of activating the starved macbook battery. If it is useful, you can save it.
Activation method for starvation of macbook battery
The first method: check the sulfation degree of the electrode plate.
The electrode is slightly sulfurized, so the battery can be charged evenly, and it can return to normal in a day or two. The electrode plate is heavily sulfurized and can be charged and discharged through "hydrotherapy" to restore to normal. If the battery is severely sulfurized, then the ordinary repair method is ineffective. The high resistance repair of the repair instrument can be used to increase the voltage to more than 10V, and then charge the battery. It is possible to reactivate the battery.
The second method: separate the battery pack and charge it by one
Once the battery is not charged, the battery pack can be disassembled to charge a single battery. Because the battery has been stored for a long time, the charging time is longer than usual.
The third method
The charging system with different parallel connection methods can be divided into single parallel connection and whole group parallel connection. The principle is the same for all enterprises. The single parallel connection method can use one of its own batteries that can be normally charged and saturated to directly connect the positive pole to the positive pole, and the negative pole to the negative pole on the low current battery. The whole set of parallel connection is to select one set of battery packs with the same voltage and saturation, use the two sets of research battery technologies in series, and then connect the two sets of total positive and total negative materials with batteries. According to the principle of "battery charging cell", normal operation charging can be achieved.
Fourth method: choose a smaller charger for charging
If the battery pack is 60V20AH, 48V-20AH charger can be selected for charging. After charging for at least two hours, the voltage rises significantly, and then use 60V-20AH charger for charging. Usually this method is feasible.
The fifth method: special charger
Some chargers have the function of repair. No matter how many volts the battery is, it will soon return to its normal state.
How to Wake up the Sleep Status of the Macbook Battery
1. Check whether the computer supports this function; View method: click "Start" - "Run"; Then enter "CMD" and click OK;
2. Enter "powercfg - a" in the command window, and remember - there is a space in front of it; Press "Enter" after completion; The result shows Standby (S3); Explain that your machine supports the sleep function. If not, you need to contact the computer manufacturer to upgrade Blos.
3. Solution to system settings: In many cases, this function is not enabled. Right click My Computer, and then select Manage;
The above is about the activation method of the starved macbook battery. First, check the state of your computer, and then activate it according to the problem. The above methods can be used.
