Fitting a power supply - we give you a helping hand
It is very important to choose the right power adapter for your laptop model. Forced downtime can be reduced to a minimum by following these few simple rules:
You can read the basic parameters from the label on the bottom of your laptop, these will be: POWER (W), VOLTAGE (V), AMPERAGE (A). The following points will dispel any doubts that may arise when choosing equipment:
1. Power (W) This figure represents the minimum value that a new power supply should have. There is nothing to prevent the use of a higher wattage product. This means that the power supply is under less strain and will therefore heat up less.
2. Current (A) here, as with POWER, the value on your new power supply can be equal to or greater than the value on the laptop's rating label.
3. Voltage (v) the number for this parameter is more strictly required. Only +/- 0.5V variation is allowed.
The last and equally important issue is the plug. Without it there is no use! There are no exceptions here, it must be identical to the original. The size given means the outer diameter and the inner diameter of the plug. If a comparison on the basis of the presented picture is not enough, it will be necessary to measure it, which will finally reassure you in your choice.
