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.
