Power adapters like everything can become worn out over time. In fact, the wiring of power adapters is especially prone to becoming frayed due to normal use. In other cases, a power adapter may have been lost.
Unfortunately, not many laptop manufacturers will replace a worn out adapter. This can become an even bigger problem due to the fact that the life cycle for laptops in the marketplace is extremely short. Power adapters for a certain model are not likely to be manufactured for very long.
Due to these facts, at some point, many laptop users will be forced to find power adapters that may not be exactly the same but still match up with their laptops. This can be a difficult task. However, with some knowledge of what to do, this can be much easier.
First, you'll want to look at the user's manual for your laptop. It should give specific specifications for the AC power adapter that came with your laptop. Things you will want to look for and write down include the adapter's current, voltage, and wattage capacity.
The voltage capacity of an adapter that can match up with your laptop does not have to be exactly the same as your previous adapter. However, it should be in a similar ballpark of about 10 percent. The current, however, should be equal to your previous adapter if not higher. Like wise, the wattage of the new adapter should be equal to or higher than the previous adapter.
Another thing that matters greatly is the size of the plug-in of the adapter. If it is too small or too large, it won't be able to fit into the port on your laptop to provide it with power. Before you purchase a new adapter, try to examine the plug-in. It should appear to be about the same size and shape. Slightly smaller or large plug-ins may still fit into the AC adapter port. However, there is only so much leeway.
Lastly, you should see if the adapter works properly once obtaining it. Plug it into an outlet and let it charge your laptop. If it doesn't work, send it back and try to obtain a better match.
