During use, and especially on overcharge, the water in the electrolyte splits into hydrogen and oxygen. The battery begins to gas, which results in water loss. In flooded batteries, water can be added but in sealed batteries, water loss leads to an eventual dry-out and decline in capacity.
Virus. The first possibility, and maybe the most common computer ailment, is a virus. Viruses can do any number of things to a computer, but while theyâre stealing your data or ruining your files, theyâre using up precious system resources that could be used for other important tasks.
A freeze up can also be caused by low refrigerant and improper fan operation. Low refrigerant levels make the coils too cold, and a faulty fan prevents air from moving. Faulty thermostats and drainage problems are often causes of a freeze up. In the cooling process, an AC unit condenses water vapor into liquid that drains outside. If the coils are frozen, the ice will cause a blockage for the drain hole.
