Lenovo g50-45 is very affordable notebook with a bright display light weight design but it’s keyboard abd short battery life. The original battery goes down to a hour and thirty minutes. After only 2 yrs of School use. And the system was trying to run so many installed apps and junk stuff. It is very slow laptop and it keeps freezing so I’ll suggest you but before purchasing get all the information because according to me I got many problems like you bad battery problem and many others so this for me it’s not a good laptop I don’t know about this just because of that problem.
