It and I will thank you. I opened the case and was greeted by a colony of spiders. They are also hard on computers. But many might be surprised by the number one killer of the all important machine. Yep, the one source we all take for granted can kill a computer faster than the flick of a light or slower than a very, very tired Energizer Bunny.
Electrical current supplied by the local power plant is anything but consistent.
When the lights flicker a condition known as an under voltage occurs and when they get extremely bright we have a spike. Surge protectors provide inadequate protection. They typically only protect against spikes. By using an internal battery they provide consistent current to a computer. They cost more, but are well worth the price.
