Determine how good or bad notebook computer components, laptop maintenance is the most basic requirement of the. In order to help to determine their own DIY notebook components of a good or bad, I collected a component of the quality of discrimination methods. No contact with the maintenance of a friend to see now! Classes, Hei hei! 1, resistance Unless the nominal production error, otherwise the resistance will become only resistance, resistance damage does not exist resistance smaller situation. When the resistance over the size of the error to allow that resistance could be damaged. 2, capacitance Capacitance characteristics:-exchange, at DC. If the capacitor surface damage, leakage or drum kits, the capacitor has been damaged. Multimeter with two-pin capacitance measuring the resistance, if it is 0, capacitor damage. Sometimes on the motherboard capacitance measurement of resistance to the two pin-0, because the pins on the motherboard between the two lines are interlinked. 3, inductors ICP features:-DC, at the exchange. If multimeter measuring inductance between the two pin-resistance is greater than 0, inductors damage. 4, crystal No damage to its own frequency, voltage amplitude decision crystal. 5, FET Table T to any gate, another two-test resistance of infinite; measured gate and drain again to the small resistance, is a table T access gate after measuring the same source resistance, another repeat of the table T Process, the resistance to 0, FET normal.
