Compact Chromebook for light tasks

The Acer C721-25AS is a refurbished 11.6" Chromebook built around an AMD A4-9120C dual-core processor with 4GB memory and 32 GB eMMC storage. It runs Chrome OS on a 1366 x 768 wide screen and includes 802.11ac wireless LAN plus Bluetooth 4.1. A spill-resistant keyboard and 3-cell lithium-ion battery complete the core package.

Storage capacity and everyday headroom

The 32 GB eMMC drive holds the operating system and a modest set of Android or web apps, leaving limited room for large local files or offline media libraries. 4GB shared memory handles a handful of browser tabs and lightweight extensions, but heavy multitasking or memory-intensive web apps will hit the ceiling quickly. A micro SD card reader provides removable expansion for documents and photos.

Thermals noise and power in normal use

Passive cooling keeps the chassis silent during typical browsing, video playback and document editing. The low-power AMD A4-9120C and integrated Radeon R4 graphics draw modest energy from the 3-cell battery, allowing several hours of unplugged work. Surface temperatures stay comfortable on a desk or lap during ordinary classroom or office sessions.

Perguntas sobre este artigo

Will the AMD A4-9120C processor and 4GB memory handle the same Chrome OS tabs I ran on my older Chromebook?

The dual-core AMD A4-9120C with 4GB RAM runs Chrome OS smoothly for typical browsing and classroom apps, matching or exceeding many older 11.6" models.

How can I confirm the 1366 x 768 display and Radeon graphics are working correctly after first boot?

Open Settings > Device > Displays to verify the 1366 x 768 resolution, then play a 720p video — smooth playback confirms the integrated Radeon R4 is active.

Does the box include a Micro SD card for extra storage beyond the 32 GB eMMC, or must I buy one separately?

The Chromebook ships with a Micro SD card reader but no card; you purchase a Micro SD card separately if you need more than the built-in 32 GB eMMC.
