Mobile Phone Battery Testing Method

Mobile Phone Battery Testing Method With Multimeter 

Fallow Some Step to Test Battery Voltage 

Step 1 Set Multimeter To DC Voltage Range at 20 V.

Step 2  Multimiter's red prob will touch the battery's positive and black probe on the negative then the 3.7v Reading should come. 

Step 3 If it is not coming then the battery is bad.
Step 4  If the voltage is less than 3.7 v, the battery needs to be re-charged or boosted.
Step 5  If the battery voltage of 0.00V after charging or boosting, the battery is bad.

To charge a mobile phone battery, 2 pin is required. But QUS it arises, why the third terminal ? This third term is called bsi which is very impartent. 

When the battery is removed without turning off the phone, the BSI circuit interrupts, which provides information to the processor to prevent any kind of malfunction.

What is Device driver in PC or Laptop

What is Device driver 

What is device driver -A device driver is software that interconnects high-level computer programs to computer hardware devices, and also controls all the hardware connected to the computer. 

We also call it software driver in common parlance, such as sound driver, lane driver, mother board driver etc. All hardware devices have their own software driver. With the help of which these devices are connected to the computer, due to not getting the right driver, your hardware is not working properly.

What is Device Driver and how to work 

To create a driver of a hardware device, the programmer has to write code in a high-level, because that driver can work with that hardware. 

But both the operating system and the device hardware use different languages. They do not understand each other's language. In this case, the device driver acts as a translator, and changes the languages ​​of both.

For example, the printer is your hardware. In which you have to take a print out of a computer file. So you will instruct the computer to print and by computer this instruction will go to the printer by the device driver and the printer will print out your file. The main job of the driver is to instruct the computer connected hardware. So that it can work fully.

--------------------------------------------------------------------------------------------  -----------------------------------------------------------------------------------

Note: There are many types of drivers. It is absolutely not necessary that companies that make device hardware write their own driver. Some devices are designed according to the published hardware stander. Whose driver is made by Microsoft itself

BIOS (basic input/output system)

What is BIOS (basic input/output system) In PC and how it Work 

What is BIOS-Bios is the first software program system. They launch or start your system "In a PC system the main BIOS is stored inside a microchip on the motherboard (mainboard), and your computer has the first piece of software when you (boot up) turn it on. The purpose of a BIOS is to make sure that everything plugged into the computer is working properly or not. It brings life to the computer, and the term is derived from the Greek word  bios means "life"

BIOS image 

The BIOS's job is to boot the computer, sometimes called "booting up". This is the process that the computer prepares to use when it is first powered. When the computer is powered on, the BIOS starts and performs a power-on self test (POST). During POST, the BIOS will check various input and output devices in the computer such as computer processors, memory, video card mouse keyboards and others to ensure that they are present and functioning. 

After the POST is successfully completed, the BIOS gives a message to load an operating system, usually located on the computer's hard drive. When it finds one, it starts loading. And the operating system controls the system..

--------------------------------------------------------------------------------------------------------------------------

Note---- The configuration data used by the BIOS is stored in an EEPROM chip or a CMOS chip which is backed up by a battery. This data includes all of the basic configuration data, including device types and also the date and time.

1.   Clean the display connector on the PCB. Wash the parts in the section.

2.   First find the light section in the mobile, a diode boost coil and capacitor are seen near the charging ic in the light section.

3.   First of all, check whether the boost voltage (20V) is being attained by hot testing at the output of the diode.

4.   If voltage is found, check the beep from the anode end of the diode to the tips of the display connector. If the beep is coming, the boost voltage should also be 20 volts.

5.   If the normal voltage is found on the diode, then check all the capacitors and boost coil in the light section.

6.   Boost coil or capacitor is bad, then remove and replace it from another light section.

7.   On one of the pins of the IC, EN signals come from the CPU, which, when the display is active, comes from 1.8 bolt to 2.8 bolt on a register there, if the voltage is coming but still the output voltage is not coming, then the IC Change

How to check mobile phone shorting by digital multimeter ?

In this article, I have shared the tips that can help you know that a how to check mobile phone shorting  by digital multimeter step by step. Share in next article After checking how to remove it.

What Is mobile phone shorting ?

The mobile phone PCB is made up of several layers. Which leads to different tracks. When the water damage overheating or the mobile phone falls to the ground, these tracks are opened, which are called open track, or are joined together, which is called short track. Those who create shorting  in mobile phones. Sometimes shorting  comes due to components in mobile phones such as diode register capacitors or ICs.

Half Shorting

Mobile phones start taking more amperes in half Shorting. If the battery accepts its requirement so much, the mobile phone is on. Because of which mobile phone batteries start to swell and run less. Mobile phone can also be dead due to half Shorting. Half Shorting in mobile can be from any component or section, such as capacitor diode, register, power IC, CPU, network IC, etc.

Full Shorting

Mobile phones go dead in Full Shorting. Full Shorting can come from any component or section of mobile phone. Such as diodes, capacitor, power IC, PFO, CPU, network IC,etc

How to check mobile phone shorting by digital Multimeter Step by Step ?

In mobile phones, Shorting is detected by Digital Multimeter with cold testing.

Step1 Turn on the multimeter and set it to beep mode.

Step2 Connect the red probe of the multimeter to the negative of the battery connector and the black probe to positive.

The readings ranged between 250 ohms to 650 ohms.And when you change the probe (red probe to positive and black probe to negative) when reading 1 in the multi meter, the mobile phone is correct.

Step3 Mobile phone is half shorting when the reading comes on both sides.

Step4 Full shortening occurs when the sound of the beep comes.
