If you're having some strange problems with your computer, it could be that the power supplied to your machine from your wall outlet is dirty. Or perhaps you could been the recent victim of a power surge or spike during a hydro-blackout, or storm. Power surges occur, when too much hydro-is transmitted down the line even for just a nanosecond or so. It can often be caused by other electrical units connected to the same circuit. Sometimes a computer may not have enough power, due to a heavy draw from other items such as air conditioners.
Fortunately the solution to this problem. What you need is an uninterruptible power supply, commonly known as the UPS. This basically introduces a middleman/protector between your computer and the Hydro coming from your wall socket. The UPS plugs into the wall and draws energy to charge a battery. The power from the battery, as I use the power your computer. By adding this extra step, power surges, power sides and blackouts will have little effect on your computer. When the power goes out, the batteries on the UPS takeover and continue to supply power to your computer. Depending on the size of your batteries, you be able to continue using your computer for several minutes to several hours. Hopefully this gives the power problem enough time to correct itself. Generally speaking the price of a UPS goes up with the size of the battery inside. At the very least, having only a small battery will at least give you the time to save everything you're working on, and powerdown your computer systematically, and safely.
There are a few different types of power supplies you should consider. One type of uninterruptible power supply, is called the same by UPS. The other type of uninterruptible power supply, is called a continuous UPS. Both UPS types share some similarity. They both remain plugged into your standard Hydro, and charge a set of internal batteries. A standby UPS, will only switch to battery power, for your computer, whether it detects a power surge, or a power blackout. The stand by UPS can switch the battery power very quickly, in only a few milliseconds. With a continuous UPS, your computer is always running from the battery. The UPS is constantly charging the battery with power from your standard Hydro. If the power goes out, there is no need for the UPS to switch to battery, and there is no delay of power supplied to your computer.
