I'm also looking Dell business laptops - do you have any experience of model types? A colleague recommended looking at the latitude series.
My research says that Latitude is the one to buy. Made for hard business use. Just make sure it has either Windows 10 or 10 Pro and is not "OS".
Donnie, it's on a 2nd battery now. I really think the connection is shot as it's loose as a goose. That requires removing a million screws and then hoping it's detachable and not needing a motherboard solder from what I read.
Time to upgrade. I only paid $80 U.S. for it and it has lasted approx 3 yrs.
