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.

How to Fix Device Driver Common Issue

Fix Device Driver Common Issue in Windows 

While running the computer or laptop, you may have noticed that some of its devices stop working automatically, such as wi-fi shutdown, web cam not working, many of these problems are caused by the device driver getting corrupt or outdated. its problame will be created by device driver common issue

How many Application work with device drivers

• Printers
• Video adapters
• Network cards
• Sound cards
• Local buses of various sorts—in particular, for bus mastering on modern systems
• Low-bandwidth I/O buses of various sorts (for pointing devices such as mice, keyboards, USB, etc.)
• Computer storage devices such as hard disk, CD-ROM, and floppy disk buses (ATA, SATA, SCSI)
• Implementing support for different file systems
• Image scanners
• Digital cameras

Note : - If any of these device drivers cause problems, then the device hardware related to it stops working. By updating the device driver, and fix windows device driver common issue

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.
