Comments started out preachy ended up funny . <| sep |> Check the link I just posted <| sep |> tbh . not really . mostly jokes . i ' m just a poor web developer with a dry idea well . pls halp <| sep |> I don ' t have the ZW 3 , but on both my ZW 2 and my moto 360 wifi killed my battery . Try disable wifi if you haven ' t tried it already . <| sep |> My first reassemble went something like that . I was camping and reading a book on how to build computers for a week , so when I got home I disassembled mine and put it back together . It had a very old CPU with a builtin fan that sat on the Mobo like a RAM stick . First and last one of those I saw before working with the tiny squares we all know and love now . Well , disassembly went fine , reassembly seemed to go fine , too , but it wouldn ' t power on . Apparently my first build boiled down to me not shoving the CPU in far enough . Fun times Other than that I think my worst offense was RMAing a dead Motherboard only to find out I misread the manual and installed the Power Button Pins incorrectly . Hotwired 2 other pins on the replacement Mobo and it started up just fine . 2 day delay for nothing x . x
