What are two ways customers can open a support case for ChromeOS?

B. Contact the device manufacturer: ChromeOS devices are manufactured by various companies like Acer, HP, Lenovo, etc. Each manufacturer provides its own support channels, including phone, email, or chat support. Customers can contact the manufacturer for hardware-related issues or specific device configurations.

D. File a case through the Customer Care Portal: Google provides a customer care portal where customers can submit support cases online. This portal allows users to describe their issues, attach relevant files, and track the progress of their case.

Why other options are incorrect:

A. Chat support via the Admin console: Chat support is usually available for enterprise customers with Chrome Enterprise Upgrade or Google Workspace, not individual ChromeOS users.

C. File feedback on the device with Alt + Shift + 1: This keyboard shortcut is used to capture screenshots and send feedback to Google, but it doesn't directly open a support case.

E. Send an email to ChromeOS support: While Google has support channels, sending a general email might not be the most efficient way to open a case and get a timely response.
