2)not affordable condition like extreme cold or heat not best condition
3)not used for 6months or above
Battery checking if you have a multimeter or voltmeter to read battery(remove ups cover saftely)voltage bellow 11.4v need to recharge or no volt battery dead a chance to recover by charge
If you have warranty do not open only charging and contact you dealer to replace them
How to slove smartphone brick and odin doesn't recognize
If you are updating recovery then failed is not a hardbrick and softbrick it in the middle brick it means you can recover from using this step
Go to download mod by pressing volume up+home+power on this is based in phone or using jig
Some phone does not recognised by Odin because they do not install drives correctly please install kids and stop kies by close in taskbar,they did not using data cable they are using charging cable,not Using correct Odin versions it will work best of luck
Usb not recognizing ,usb not working,usb only charging
computer not detecting USB in my computer USB work partially my mouse and keyboard not detect in computer
How to slove this issue
1)scan with a powerful antivirus like Norton and kaspersky etc to remove malware and virus that will kill the USB function
2)change USB device or check USB device in another computer
3)update chipset driver that has been found in manufacturer website
4)change USB port into another USB port
5) open the cabinet to check the USB fuse is brokened if brokened it is need to replace

How to make a magnet
Actually electromagnet are temporary magnet.it is not a permanent magnet.it works when the elctricity pass through them.we can make a simple magnet.need things to magnet are 1.cell(using pencil cell or 9vcell or other) 2.metal(like iron etc)3.insulator wire or copper wire 4.one switch (optional)
Use a large wire connect the wire one side to the cell and the other end of wire wind the metal or coiling the metal.the remaing wire connect to the switch(not available connect to the cell directly)turn one cell wait few second the magnet ready to attract any metal object.increasing of the coil or wind yo the metal to increasing the attraction force

How to make a radio station
We can easy make radio circuit but we know about. How to simple radio broadcast station.simple broadcast station require components are capacitor,inductor,resistor etc.the inductor is signal send act as a tower and the capacitor is act as a sound booster and circuit current booster.we connect a mic to the circuit and speak when the circuit works the inductor send signals to the real FM station but the signal range is low at 30m radius.

Transformer
Transformer is electric device which boost electricity.when we will connect the input to transformer and high electricity than input electricity and reduce electricity than input mostly use stepdown transformer is used reduce electricity than input normally used in TV ,ampilifer etc

Speaker
Speaker is a device used in many electronic circuit.the speaker is produce sound that hear by our ears.speaker is used in TV,mobile etc.we connect the audio to the speaker and produce audio .how does it work.when the audio signal connected to the speaker.inside the speaker vibrating and produce sound why vibrating.inside the speaker has coil it is made up of copper.the coil transform to magnetic field when the audio signal gets the coil respond to the backside magnetic and vibration made and produce sound. The high volume connected to a speaker produce sound and distortion because the coil will heavy vibrating
Ic
The full form of IC is interfered circuit it consist about 100components make one IC is smaller and efficient.but IC is not repairable only replace
