Acer America NX.HBNAA.001-REFA Chromebook AMD A4-9120C 4GB 32GB 11.6

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.
