As a crucial part of any laptop setup, laptop AC adapters supply power to the laptop battery, recharging it for portability. While problems with AC adapters are generally rare, there are a few issues that can crop up from time to time. Here we will examine some of the most common issues that can cause and AC adapter to fail.
- Physical Damage
Since the Laptop AC adapter is an external component of a laptop setup, it can sometimes take more abuse than the machine itself. Adapters that are dropped, stepped on, or sustain other kinds of physical damage may stop functioning correctly and need to be replaced. It is important to care for your AC adapter just as you would the laptop itself, as it is a necessary part of your computer.
- Cable Damage
While it could be grouped under the heading of physical damage, cable damage is perhaps the most common cause of an AC adapter malfunction, so it deserves its own category. Cables that have begun to wear out or have been bent too sharply may begin to fail and need to be replaced. Avoid wrapping cables too tightly or bending them to avoid these problems.
- Overvoltage or Power Spike
Another common cause of AC adapter damage is a power outlet that temporarily supplies too much or too little voltage. This could be caused by a lightning strike, a power surge, or a brownout. While most AC adapters can adapt to these problems without damage, there is still a possibility they will fail. A surge protector will usually protect against surges and even lightning strikes, while an uninterruptible power supply with a battery backup can often protect against brownouts.
If your AC adapter needs replacing, you can find replacements online from laptop parts stores like Spareparts Warehouse. They carry a large assortment of Toshiba Laptop AC Adapters and Toshiba Laptop Parts as well as parts and accessories from other major manufacturers.
