AC Adaptors and Power Adaptors

Always check your computer manual for the correct ratings and the type

of Adaptor that your machine requires. Adaptors are usually rated by

Watts/Wattage(W). You can calculate the Wattage by multiplying

Volts(V) with Amps(A). This information is found on the label on the

underside of the notebook computer.

It is always best to match the wattage of the notebook and the AC

adaptor. An AC adaptor with a higher wattage can be used with a

notebook with a lower wattage rating. However, an AC adaptor with a

lower wattage rating cannot be used with a notebook with a higer

rating. The notebook will be underpowered and may not boot up

properly.

The AC adapter will get hot whilst it is plugged in and being used.

This is normal. Any device that gets hot will require ventilation. Good

ventilation prolongs the life of the device and avoids any accidental

damage.


Some points to consider:

The led light, on most AC adaptors should stay constant when plugged in

to the wall socket or AC power supply and switched on and plugged into

the notebook computer. If the light flickers or blinks then check all

connections and check the power lead. It may also turn out that the

adaptor is simply faulty.

If you have several different notebooks, all of which are different

types and made by different manufacturers, you can still use one

charger. Universal AC adaptors are supplied with different tips which

enables you to plug it into different notebook computers. However, you

cant charge more than one notebook at a time.
