Manufacturers all make a set of standard for laptop using time when designed.
Any electrical apparatus has a using life, not but always to be of long life.
Manufacturers for general family laptop design 8 hours working time, which means if excced 8 hours, probably some unexpected situaitons may happen.
Business laptops, generally are designed to be of 24 hours’ working time.
This is why business laptops’ price is very high although with a common configuration while family laptop’s configuration is very good though the price is comparatively cheap.
So the answer is quite clear: personal laptop is not business server, don’t let it run 24 hours all the time! Even you use business laptop, you should turn it off at night except it needs to be opened 24 hours for business!
Generally, laptop cannot reach the requirement of running 24 hours all the day, especially under high temperature and damp environment. Generally, when fan keeps running continually, it’s time to let it off and have a rest! If you insist letting it run, you just reduce its using life.
Definitely machine would heat when working, and overheating would influence all parts’ using lives entirely!
Accelerating to indraft more dust, blocking the intake of the laptop, too much dust attach on fan, would all slower down fan’s speed, deteriorate thermal effect and shorten laptop repair and maintenance period.
It would accelerate the aging of silica gel and increasement of laptop motherboard’s temperature, which are the main rea
