Power may indeed corrupt, as the saying goes, but in the typical Soho (small office, home office) power can be a real headache. When it comes to setting up a home office, a great deal of attention has to be paid to making sure your sockets are not being overloaded. Most computing devices do not require much power, so it is fairly safe to plug several of them into a single socket. However, in many Hong Kong flats, the sockets are few and far between and a little imagination is often required when setting up your office. In my flat, each room has two sockets, which are placed on opposite walls. Because of the thickness of the concrete walls, putting in more sockets is next to impossible. So I am left with my laptop, external monitor, desk lamp and printer plugged into one socket. I am lucky because I have an internal modem, which does not require its own power supply. As it is, the mass of wires hanging down the back of my desk is enough to give me nightmares thinking of what might happen if I ever have to move. In order to help protect against the possibility of an electrical overload, I have changed all the sockets in my flat to 13 amp, the ones with three square pins. The advantage of the 13 amp sockets is they have an additional fuse, and so offer an extra level of protection. In the plugs I use three or five amp fuses which should be more than adequate for most of the electrical devices on your desktop. I also use a separately fused strip adaptor to plug my many devices into. With these measures I should be safe enough from most power surges, but if you want to be safe from even the most powerful surge, such as a lightning bolt, then a surge protector would be a good investment. Surge protectors are little boxes that plug into the wall socket, into which you plug your computer. They can be purchased for less than $100, and should give even the most pessimistic user peace of mind. Make sure you replace your protector every few years, as the cheaper ones in particular can wear out over time. In the event of a thunderstorm, it is probably a good idea to unplug your computer regardless of how much protection you have. Also unplug the modem cable going to the telephone socket. There is some debate over whether or not telephone wires can conduct lightning and carry it to your computer through the modem. I know two people whose hard drives have been frazzled in exactly this way.
