Gateway Power Adapter

You know how complex are laptops, so you can have some idea about just how many components are inside one. Starting from the case and finishing with the power cord that connects the laptop to the wall plug, all these components are produced somewhere, by a certain company.

And it’s only natural that each component is made by a certain company that is specialized in that particular field: company X makes the best AC adapters, company Y makes the best laptop batteries and so on. You can’t expect Gateway to make all the components and accessories of a laptop like making all the component parts of a coat for example in the same tailor’s workshop. These adaptors have different models and sizes in order to fit the size of the input port of the laptop.

A certain model of adaptor, like this one for example – Gateway laptop ADP 90HB power adaptor – is compatible with a few Gateway laptop models, but not with all of them. The one you can see in these two pictures is compatible with Gateway 2521997 2521997R 6500706 6500722 ADP-90AB ADP-90HB adp-90sb bb pa1900-15. It comes together with a power cord that is six feet (almost three metres) long and that is plugged to the power supply (the wall plug) leading the power up to the adaptor.

This circuit of the electrical current id very important because it guarantees the safety of our laptops. Withour this adaptor, if the laptop were connected just by the power cord directly to the plug, it will be fried up instantly. This is because it can’t support the energy delivered by the wall plug, which has 220 or 110 voltage depending on the geographical area where you are or travel.

It is too big for it and besides, the wall plug supplies alternative current (AC) which is incompatible with the laptop functioning. The Gateway laptop ADP 90HB power adaptor has the role of transforming this AC into a DC (dirrect current) of a lower voltage – in this case 19 V. That is it “adapts” the high voltage to the lower voltage supported by the Gateway laptop.

The other end of the adaptor gets into the laptop and supplied the necessary energy for recharging the laptop battery. So, as insignificant as it may seem, it is still a vital laptop accessory becasue once the battery is low you have no other possibility of using your laptop except for using this adaptor.

It is sold for a pretty fair price , somewhere between $18 and 45, depending on the store selling it and its condition (new or used).

I can assure you this is a good investment, as this adaptor is protected from overheating and also won’t allow the battery to get overcharged even if it is left plugged for a long time. It will charge only the quantity of energy needed.1
