I dont know if it should or shouldnt run with it in ... 'old' laptops .. when the battery is faulty and
customers use it as a desktop anyway and dont want to spend the coins this works fine for ..
(some 'old' types overheat ect .. fire issue..im talking non-asus lappies, from experience.)
but .. why ? would you run a NEW laptop without the battery.. what is the point or reasoning ? just curious.
