The Google Pixelbook is a pretty fantastic laptop, but every tech product has a few bugs. Recently, some owners have been reporting a nasty reboot bug, where the Pixelbook will randomly restart while in use. The frequency varies from report to report, with one even saying it occurred every 1-10 minutes. Yikes.
Thankfully, the glitch has now been fixed, at least according to Google.
