When preparing previous laptops for long-term storage, I'd just pull out the replaceable battery and kept it outside the system. What is the safest way to store newer laptops that have integrated batteries (not intended for removal by average computer owners)? If the laptops aren't going to be used for a while, is there a "shipment setting" or some way to disable the battery without actually disassembling the system, or will they be okay with the batteries left still connected?
(Update: The laptops are Lenovo 300 isk series and 110 ACL)
