Does anyone use an external battery power source other than the battery that is attached to the laptop itself? We have 2 folks who just got these really nice Sager laptops and even with power settings ramped down the battery life is only 42 minutes without doing any cad or revit. That’s 42 minutes of idle time. There is no option to upgrade the laptop battery itself. What I was wondering is if there is such a thing as an external battery that you can plug the laptop into and get at least 1 hour out of? They already have 2 batteries for a combined total of almost 1.5 hrs of battery life. That’s really pathetic in my book. Or do I just tell my engineers they are SOL?
