Memory Module 2-Power 2P-S26391-F2133-L400 4 GB DDR3L 1600 MHz
The 2-Power 2P-S26391-F2133-L400 is a 4 GB DDR3L 1600 MHz memory module designed for laptops. It offers a compact upgrade option to improve system responsiveness and multitasking performance without replacing the entire device. The module uses low-voltage DDR3L technology and carries a lifetime warranty from 2-Power, with guaranteed compatibility for supported systems.
This 4 GB DDR3L module increases available RAM for smoother application switching and faster load times. Running at 1600 MHz with CAS latency 11, it balances performance and energy efficiency for mobile systems. As with other 2-Power memory products, compatibility is tested and the module is covered by a lifetime warranty.
Power off the laptop, disconnect power and remove the battery if possible. Open the memory compartment according to the laptop manufacturer’s instructions, ground yourself to prevent electrostatic discharge, and remove the existing module if replacing. Align the notch and insert the 2-Power DDR3L SO-DIMM at a 30–45° angle until the retention clips engage, then press down to lock it in place. Reassemble the laptop, reconnect power, and verify the system recognizes the new memory in BIOS or the operating system.
Confirm your laptop supports DDR3L SO-DIMM and accepts 4 GB modules at 1600 MHz before purchase. If your system originally used standard DDR3 (1.5V) memory, check manufacturer documentation for DDR3L (1.35V) compatibility. For optimal results, install memory in matched pairs where supported by the motherboard.
