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.

Resetting an Acer Chromebase

Resetting a ChomeOS machine is different to CloudReady. The later disable powerwash by default.

According to Acer, there are three different methods to reset. I restore to factory default by:

  1. Click on the displayed time on lower right corner.
  2. Open the ChromeOS setting page by clicking ⚙ in the dialog.
  3. Search for “powerwash”.
  4. Run to reset everything to factory default.
