Sometimes you can obtain "battery conditioning" utilities that work with the laptop's power management smarts. It's something provided by the original design manufacturer, and may only be available to service techs or through tech support. The actual function they provide varies. It may mean discharging at an optimal rate for recharging or it may just sync the battery management features with current battery condition as determined by the manufacturer. Check with the laptop vendor's support & download areas for your model.
It could be that his laptop battery is nearing the end of its useful life. Battery age and type would help answer that question.
Otherwise, what those guys said.
