Mini How-To

Replace internal battery in Acer Chromebase

When I got the second-hand Chromebase, I cannot connect to my WiFi router. It’s due to the wrong system date and time. It won’t keep the updated setting because the battery is dead already.

Then I open the case with the iFixit Opening Tool beginning from the lower speakers. There is a motherboard in the middle. Take off protections to replace the CR2032 battery as below.
