If you use Windows and your computer does not have a custom battery management tool, there is no way to modify the battery charging threshold. Sony VAIO machines often include a "VAIO Control Center" that allows you to do the same thing. For example, some Lenovo laptops include a "Power Manager" utility that allows you to change the charging threshold. If your computer supports custom battery charging settings, you can modify the threshold using a control panel or software utility. Your ability to set the charging threshold is actually dependent on the hardware, since the charging is controlled by a hardware component. Since manually setting the battery charging threshold is a rather advanced option, there is no way to configure this setting on many laptops. If you set the charging threshold to something lower, like 80% for example, the laptop would initiate the recharge less often, potentially prolonging the life of your battery. Therefore, if you leave your laptop plugged in to a power source and don't use it for several days, it may initiate a charge several times to top off the battery at 100%. Therefore, some computers allow you to set a "charging threshold" that will only charge the battery once it falls below a certain level.īy default, most laptops charge the battery when the charge falls below 95% or 96%. But repeatedly charging the battery can reduce the overall life of that battery.
That means the laptop battery must be charged on a regular basis. Answer: Laptops are portable machines and therefore most people run their laptops off battery power more often than AC power.
