Guidelines for Choosing the Right Laptop Power Supply
You can minimize forced interruptions in operation by following a few simple guidelines mentioned in this paragraph.
Remember!
The basic parameters can be read from the label located on the bottom of the laptop marked as INPUT or on the nameplate of the original power supply described as OUTPUT . These will be: POWER (W), VOLTAGE (V), CURRENT (A). The following points will clarify any doubts that may arise when choosing the equipment:
1. POWER (W) – this number indicates the minimum value that the new power supply should have. There is no prohibition against using a product with higher power . This way, it will be less loaded, and consequently, it will heat up less.
2. CURRENT (A) – just like in the case of POWER, the value on the new power supply can be equal to or greater than the one indicated on the laptop’s nameplate.
3. VOLTAGE (V) – the number for this parameter is more strictly required. Only a fluctuation of +/- 0.5V is permissible.
The last and equally important issue is the PLUG . You can’t do without it! Here, there are no exceptions, it is necessary for it to be identical to the original . The given size indicates the outer diameter and the inner diameter of the pin. If the comparison based on the presented photo is not sufficient, a precise measurement will ultimately confirm your choice .
The Impact of Power Supply Choice on Laptop Performance
Matching the right power supply to your laptop model is very important, as it affects several key aspects, such as:
