Overview

The Acer Aspire S3-391-9445 is a 13.3-inch ultrabook designed to balance portability with usable performance. At its core is an Intel Core i7-3517U processor running on the HM77 Express chipset, paired with 4GB of DDR3 memory and a 256GB solid-state drive. The SSD is a notable inclusion that keeps the system feeling responsive during boot, wake-from-sleep, and application launches. The 13.3-inch CineCrystal display provides a 1366x768 resolution with an active matrix TFT panel, delivering adequate visuals for productivity and media consumption.

Connectivity options include dual-band 802.11a/g/n Wi-Fi, Bluetooth 4.0, and a Gigabit Ethernet port for wired network access. The port selection features two USB 2.0 ports, an HDMI output for external displays, headphone and microphone jacks, and a 2-in-1 card reader supporting SD and MMC formats. Weighing just 2.93 pounds with a 3-cell lithium polymer battery, the Aspire S3 is built for mobility, though the smaller battery capacity means users may want to keep a charger handy for longer work sessions. It ships with Windows 7 Professional 64-bit, and integrated Intel HD 4000 graphics handle everyday visual tasks.
