In 2007 I had a Gateway convertible computer. This thing was like 14 or 15 inches screen size, it had to have weighed 5 pounds with the battery attached, closed and without worrying about the battery’s additional thickness it had to have been an inch and a half thick. The thing is, it worked fine.
The Dell Inspiron that replaced it has one of those soft shell lithium batteries that inevitably bulge and stop the trackpad from clicking, there’s a fan that scrapes its housing because of how tight the clearances have to be…all so the thing can be about a half inch thick? Why?
