2-power 2P-S26391-F1382-L400 - 4 GB - 1 x 4 GB - DDR3L - 1600 MHz

Upgrading an older laptop can be a frustrating experience—slow boot times, freezing applications, and constant disk swapping make even basic tasks feel like a chore. The 2-POWER 2P-S26391-F1382-L400 4GB DDR3L SODIMM module directly addresses these bottlenecks, giving your notebook the headroom it needs to handle everyday multitasking, web browsing, and office productivity without breaking a sweat. As a drop-in replacement or expansion for compatible systems, this single 4GB stick delivers a tangible performance boost at a fraction of the cost of a new machine.

Who is it for

This module is ideal for students, home users, and small business professionals who rely on a laptop for daily work but are held back by insufficient memory. It is particularly well-suited for older ultrabooks, thin-and-light notebooks, and small form factor PCs that require low-voltage DDR3L SODIMM memory. If your system currently has 2GB or 4GB of RAM and struggles with multiple browser tabs, document editing, or light photo management, this upgrade will restore smooth responsiveness.

Tips

Before purchasing, verify that your laptop supports DDR3L SODIMM memory and has an available slot. Many systems with soldered memory cannot be upgraded, so consult your device manual or manufacturer's website. For best results, install the module in pairs (if your system supports dual-channel) using identical sticks. Always handle the module by its edges and discharge static electricity before installation. After upgrading, run a memory diagnostic tool to ensure stability.
