moo Posted November 6, 2006 Report Posted November 6, 2006 My laptop's battery has degraded to the point where I get about 30mins' worth of use out of it when unplugged.I have exactly the same problem.This is called "battery memory", and is caused by constant partial discharge then recharging, rather than using the battery's full capacity (or at least varying the amount used). Boerseun's friend was using a rather "Russian Roulette" approach, when all that is usually required is to completely discharge and recharge a battery via normal use a few times. http://en.wikipedia.org/wiki/Battery_memory NOTE the issue about battery "packs" (your computer prolly has a sealed pack, so use discretion): "Because some cells may discharge before others, they are charged in reverse by the remaining cells, severely damaging them. To avoid damage to the other cells, each cell must be individually discharged, not the entire pack as a whole." My opinion: this probably depends on the rate of discharge, with a heavy discharge being more likely to cause damage than a lower rate. So if you try this with your laptop, let it run down in sleep/standby etc. instead of while it's working hard. My old laptop is Win 9x so I just boot to DOS and let it run down from there, which also avoids any Windows hiccups. Back on topic: Who am I and what am I doin' here... :shrug: moo Quote

A bruised and battered turtle crawls into a police station. He says to the cop: "A gang of snails just beat me up!". The cop says: "Did you get a good look at them?".
