Batteries/Power/Plugs

Did you know that your laptop runs at 50% performance when unplugged??

Its true....From the factory your settings are set to 50% when unplugged. The reason is two fold...

First- the power adaptor is usually 19v and the battery is 12v the simple difference should indicate it would be different

but its not as simple as that. Lithium batteries are unstable and have a limited number of cycles

in each one's life, plug, unplug, plug, unplug this back and forth eats up the life cycles, diminishing the lifespan. 

The same can be said of letting the battery completely drain to zero. The laptop was designed to operate

at its top voltage/ amps and can be used unplugged for random short periods of time not depleting totally.

Second- Heat is the enemy of lithium batteries ensure your laptop runs as it is supposed to with fans running clean and free of debris

when gaming or video rendering or any high power required task be sure to adjust the fan curvature to higher speeds at lower 

intervals on the temperature spectrum. Using a fan control program will alleviate this, a good free option is MSI Afterburner

However there are several from most major brands for free 

Asus/MSI/Intel/Generic CNET 

Third-Dell says there is no need to unplug your laptop

Asus says you should unplug and drain below 50% every second week

HP says to do it once a week

My perspective seeing the tons of dead and damaged batteries

Dell is too lack Hp is too far

Asus is the closest to extend your battery life

Keep it plugged in during heavy tasks as your cpu, gpu etc run at 50% its the reason the manufacturer says to make sure its

plugged in when you install OS.
