It is vital to adequately account for electrostatic discharge (ESD) when doing computer or laptop repair.
ESD does not always completely destroy a component, but can cause damage that may not show up until a year or more later.
When the computer starts freezing or blue screening and you put it down to a bad memory chip. It’s just possible that chip was fine until it was mishandled.
Using static control procedures has been shown to reduce hardware failures and glitches by as much as 35%.
I have installed anti static bench matting and grounding so that the repairs I do and the computers I build last a long time.
