What are these two dial-like graphics?
Hi, I'm an inspiring Chromebook technician and I took the cover off, then the battery, exposing two interesting things. A sticker reading “Wonderful sputtering WDF” with a date, written in Ymd format, “2016.06.11 N,” and two dial like graphics, one having the numbers 0-3 spaced evenly, as well as a similar graphic with the numbers 0-9. There is also a graph coupled with a recycling symbol displaying the number 7.
What are these and what do they mean? I belive the Wonderful sputtering WDF sticker is a manufacturing sticker put there by whoever assembles these things, possibly by a worker. The Ymd format leads me to believe it came from China, or other similar country.
Bu iyi bir soru mu?
