Major faults in power adapter for laptop
- fault in the oscillator for various reasons, including and the burning of the transformer
- breakthrough in the rectifier diodes or deterioration parameters of electrolytic capacitors - it can cause serious damage to the laptop
- fault in the transistors of the inverter voltage - missing output voltage
- incorrect operation of the controller, which changes the mode of operation of other components in the power adapter. A power adapter for laptop with a similar problem can seriously damage the laptop.
Reasons for the occurrence of damage to the power adapter of a laptop
A causes of failure in the power adapter may be also and working with an inefficient battery. It is recommended that immediately after detection of abnormal operation, mainly a moment of autonomy of the laptop, the storage battery immediately to be replaced with a new one. If for some reason it can not immediately be put a new battery, the inefficient one must be removed from the laptop and till providing a new one to work only with adapter - without a storage battery.
You must know that there are damages in a charger of a laptop which can seriously damage the laptop - leading to expensive repair of the laptop.
Because of the not very high value of power adapters initial is made diagnosis in order to determine the value of the eventual repair. In some cases it is cheaper to buy a new power adapter for laptop than to repair the old one.
Computer repair shop Aksis BG Varna performs diagnosis and by request of the customer, subsequent repair of an adapter of laptop.
When it appears that the repair of the adapter is financially disadvantageous, in the absence of an original, it must be carefully selected an analog power adapter - to seek maximum matching key parameters such as output voltage, polarity and diameter of the contact jack.
