You can reduce the forced break in activity to a minimum by following these simple rules: You can read the basic parameters from the label on the bottom of the laptop, they will be: POWER (W), VOLTAGE (V), CURRENT (A). The following points will dispel any doubts that may arise when making your choice of equipment: 1. POWER (W) - this number indicates the minimum value that a new power supply should have. Nothing prevents you from using a product with a higher strength. Thanks to this, it will be less loaded, and therefore it will heat up less. 2. CURRENT (A) - here, as in the case of POWER, the value on the new power supply may be equal to or higher than that indicated on the rating label of the laptop. 3. VOLTAGE (V) - the number for this parameter is more restrictive. Only a fluctuation of +/- 0.5V is allowed. The last and equally important issue is the PLUG. You can't move without it! There are no exceptions here, it must be identical to the original. The size shown is the outer diameter and inner diameter of the pin. If a comparison based on the presented photo is not enough, a measurement will be necessary, which will ultimately confirm your choice.Confidence confirmed by a warrantyYou value the quality of purchased equipment so our projects and solutions are focused on meeting your expectations.
