If your computer is tripping the circuit breaker that means it is drawing too much power from one outlet. Please do the following：

1. Please make sure the computer is plugged directly into the wall outlet and do not use extension socket or other multiple outlet extension cords with the computer.

2. If the use of extension socket is necessary, avoid combined usage with other higher powered household appliances such as TV, audio amplifier, etc…

3. Contact your local electrician for information on how you can upgrade your house to accommodate higher electrical draw.
