How to Repair Cellphone Not Charging, No Reponse, Charger Not Supported Problem Issues


There are few types of charging problem issues like Not Charging, No Charging Response and Charger Not Supported.
A problem issues with "Not Charging" shows on a display when a charger is being plug-in, this problem occurs when a required current or voltage is not enough to boost up  and charge the mobile phones battery.
One reason of this problem is  a faulty BSI Line, a BSI line is a Battery Size Indicator that tell the charging control circuit how's the batteries working status.
not%20charging%20response

The battery has a BSI output indicator terminal that connected to its negatives terminal with  desired value of resistor on it.
battery Bsi

One other charging problem issues is the No charging response when a battery charger is being plug-in, it stays no response or nothing happens.
One reason of this is a faulty protection circuit section. this happens when there is no voltage reach to charging circuit indicators and controls. If the protection circuit breakdown this will result to "charging no response" situation. You need to check each components for short and open circuits. You may start from the fuse then to the coil and the diode.
Charger Not Supported problem is cause by a faulty BTEMP thermistor component, BTEMP stands for Battery Temperature, This is the one that monitors the battery temperature status during at charging status, if this one having a problem , it wont allow any charger to proceed to charging stage.
This all, is only a brief explanation of how charging problem issues occurs, while charging the mobile phones .
There are lots of ways on how to troubleshoot each and every kind of handsets. Hope at least, this one let help you understand how charging problem issues occurs, and by this you can gain ideas to move into a stage where you can practice how to troubleshoot this kind of issues.

SMD Capacitor

The types of capacitor which is commonly used in small space circuit like the cellphone uses the Tantalum type of capacitor, 
Tantalum capacitors are used in smaller electronic devices including portable telephones, pagers, personal computers, and automotive electronics.
It also offer smaller size and lower leakage than standard. .
There are two types of Capacitors used in Mobile Phones Circuits,
The Polarized and Non-Polarized Capacitors.
This are the Capacitors may look like  that are being used in mobile phones circuit.


SMD

The Polarized Capacitor 
Tantalum Capacitors which is polarized, and may be used in DC circuits. Typical values range form 0.1uF to 470uF.
Standard Tantalum values change in multiples of 10, 22, 33, and 47. Normal Temperature Coefficient [TC] for Tantalum Capacitors is +5%.
Polarized capacitors are typically used in large voltage situations, such as DC line filtering to reduce noise related to uneven voltage levels after rectification from an AC source. Mainly measured in microfarads. Polarity is critical to these devices. They are marked with the voltage rating (usually double the circuit voltage used) as well as the farad marking. 

Non-Polarized Capacitor
Non-polarized are similar to polarized except the plates are similar metal. 

Polarized caps are typically used in large voltage situations, such as DC line filtering to reduce noise related to uneven voltage levels after rectification from an AC source. Mainly measured in microfarads. Polarity is critical to these devices. They are marked with the voltage rating (usually double the circuit voltage used) as well as the farad marking. 

non-polarized caps are typically used in low voltage situations, both AC and DC. Polarity is not critical. Measured in pico farads typically. 
Decimal multiplier prefixes are in common use to simplify and shorten the notations of quantities such as component values.
Capacitance, for example, is measured in Farads, but the Farad is far too large a unit to be of practical use in most cases. For convenience, we use sub-multiples to save a lot of figures. For example, instead of writing 0.000000000001 Farads, we write 1pF (1 picofarad).
The more common prefixes and the relationships to one another are as follows.
Abbrev.PrefixMultiply byor
ppico0.00000000000110-12
nnano0.00000000110-9

-UNIT1100
kkilo1000103
Mmega1000000106
Units
1000 pico units=1 nano unit
1000 nano units=1 micro unit
1000 micro units=1 milli unit
1000 milli units=1 unit
1000 units=1 kilo unit
1000 kilo units=1 mega unit

Tolerance

All components differ from their marked value by some amount. Tolerance specifies the maximum allowed deviation from the specified value. Tolerances are normally expressed as a percentage of the nominal value.
For example, a component with a marked value of 100 and a tolerance of 5% could actually be any value between 5% below the marked value (95) and 5% above the marked value (105).

Nokia 1280 Keypad Ic Jumper Solution

How to Identify Capacitor's Symbols and Layout

There are two types of capacitors, the Polarized and the Non-polarized. The Polarized is indicated with  ''+'' positive and ''-'' negative, meaning this cannot be change into its mounting position from a certain connection of a circuit polarity, The ''+'' positive is for the voltage supply line B+ only and the '' - '' negative is for the grounding lines. The capacitor will blown up if putting it into a non desired polarity position.
Non-polarized capacitor is a non-polar or without polarity meaning its position can be change without damaging it.
In Schematic Diagram it is stated as letter ''C'' stands for Capacitance then a mounting code and Capacitance value.
Photobucket
The Polarized indicated with desired maximum voltage value. like for example
C7597 1000mF_14V ,
the ''14V'' is the desired maximum voltage for that said capacitor.
While the Non-polarized labeled without desired voltage.
example: C2567 22pF
