How you can solve charging faults

There are all charging faults which come can as various types.Not only that but also you can get a good idea about how can you solve that all faults correctly and step by step. Charging faults are mainly of four types.

• No Charging
• Auto Charging
• Not Charging
• Charger not support

No Charging

This is the main faults when we think about charging faults. When we connect a charger with phone then phone will not be charged therefore we cant charge our phone using charger. Like that time we will try to use multicharger or external charger for charging phone battery. But dear that fault is a very easy faults for solving correctly. Ok then we are going to understand about  how we can solve that fault step by step.

• Check the Battery voltage and if it is dead change the battery( Because when battery voltage is les than 1.9V it will be not charging. sometimes that can be 2.4V for more information please check the Battery lesons for understanding battery and faults which can be come with memory effect) if its voltage is less than 1.9V you can boost it.Remember when you use new battery check its model, it must be same with old battery.

• Connect a new charger( Because when charger is damaged or work not properly that faults can be occurred.)

• Check the charging connectors( System connector ) and Battery Pin. If that parts are damaged replace new parts.( When damage or oxidation these parts voltage is not flowing through these parts therefore Battery will not charge )
 
• Then service your phone ( clean ) properly. At this time oxidation which are in your PCB will be removed)

• Finally you want to check charging line.( how can you find charging line)

• get the circuit diagram and find a charging controll IC. Nowadays charging is controlled by UEM ( Power IC ) . Then find the charging line it is a uinqe line which is connecting one end with UEM and other end with charging port.

There is a example how can you find nokia1110 charging line using schematic diagrams

After find charging line then check along the charging line , when you checking this line you will meet electronic components try to understanding about that components and check thats are damage or no using multimeter. there is a example for understanding about this step.

After the checking F2000 and L2000 if and only if damage that electronic components then you can replace taht parts  or other wise you can make a jumper as following.

If you have done that all steps and faults is not solved then finally you can check your Charging IC or UEM. firstly heat and if it is not worked then replaced a new IC. This is the correct method for solving No Charging fault.

There are easy and correct solution for Not Charging , Auto Charging and Charger not support in next pages. check that all solution and learn step by step how can you solve that faults correctly.
