Observe the following measures for a successful operation of your notebook.
Protecting Your Notebook From Power Outages
Fortunately, there are tools that can help when power supply is interrupted. Basically there are
two types of protection against power problems, a passive form such as those provided by
surge suppressors and a multi-featured back-up power source like the UPS.
Surge Suppressors
•
wise to acquire a separate surge suppressor for added protection. A surge suppressor
protects the power supplies and communication lines from electrical surges but does not
offer a back-up power source. While some suppressors have a manual on-off switch, other
types combine switched and unswitched circuits. A mix of switched and unswitched circuits
can be a useful feature since you can keep, for instance, a battery charging while shutting
off the power for other equipment.
Back-UPS units
•
allows users to save data and properly shut down the notebook. Most UPS also include
surge protection as a feature. There are two basic UPS types, the standby power supply
(the least expensive choice) and the multi-featured on-line UPS systems.
Below are tips on power protection and some hardware features to consider before
buying these devices:
Be sure to unplug your notebook, including the line to the modem, during lightning storms.
•
Always use a proper power cord to plug your notebook to the line power. When using an
•
extension cord make sure it is a reliable cord.
Look into the energy absorption features. Surge suppressors are rated by the amount of
•
energy they can absorb, which is measured in joules. The higher the surge ratings, the
better the unit. Experts say round 200 joules is the basic protection, 400 joules provide
good protection and 600 joules or more is far better.
Check if a surge suppressor has a circuit breaker or fuse. Many suppressors are equipped
•
with either a circuit breaker or fuse that will blow or trip in case of a short circuit and
severe surges. Compared to fuses, circuit breakers are preferred because fuses have to be
replaced when damaged by a short circuit.
