Admit it: the Inspiron 1525 is an aging laptop. For many of you, it’s probably pushing its third year. Laptop batteries, much like most Dell laptops, only have a 1-year life expectancy. After that first year, their capacity begins to slowly decrease. For anyone still using the original battery, I laud you; mine stopped holding a charge about a year ago.
To help offset the effects of your aging battery, you can recalibrate it. Recalibration involves “turning off your screensaver and other power management settings that put the computer to sleep. Then fully charg[ing] the laptop before letting it run all the way down until the computer shuts off automatically.” If recalibration doesn’t squeeze some extra life out of your battery, your last option is to replace it. Of course, you can go the DIY route and replace your battery’s batteries for a small cost.
