Unless I'm traveling, my Lenovo is always plugged in. Lenovo Power Manager allows you to set the charger to not charge unless it is 95% or below. Seriously after looking at the other answers, I have been using my Lenovo for almost 2 years now. Lenovo Power Manager controls when the battery is charging/not charging. Leaving your Lenovo plugged in will not harm the battery as it will only charge when it is at 95% or below.

Batteries can take anywhere from 2-8 hours to charge completely depending on the capacity. Your laptop should have a red/green light display while your computer is charging, which then turns green/blue when it is completed. The old NiCad rechargeable batteries had "capacity memory" in them. I believe it was a safety feature to prevent the battery from over-charging. However, it backfired in that if you didn't charge the battery to its complete level then that incomplete level of charge would become your new "maximum charge" level. Now-a-days rechargeable batteries are based on lithium-ion which do not have this problem. While it is still a good practice to drain the battery completely and then charge it up completely, it is not fully necessary and can even hurt your laptop's battery if you do it too much. Always charge to the maximum level whenever possible, but you do not necessarily need to drain it all the way every single time you use it. Apple designed a hardware implement to actually cut power off to the battery if the battery was charged. This allowed them to get outstanding longevity from batteries in their devices. Other laptop manufacturers just run continuous current through the battery to keep the battery charged at its maximum level at all times. Because the current runs through the battery constantly, it drains the longevity of the battery. Certainly don't leave your laptop plugged in ALL the time, but you don't worry about trying to make sure you unplug the computer if it completes charging. Maybe once every 2-4 weeks you can drain the battery completely.

Use the manufacturer instructions you got with the laptop. Otherwise use those general instructions: charge it for 24 hours (without turning it on) then turn it on, unplug it an let it charge off until the battery ends. Afterwords charge it as needed until it fully charges, about a couple of hours each time, and try turning it off before it runs out of power.
