Direct Replacement for MSI CX640

This lithium CMOS battery is built as a direct replacement for the MSI CX640 laptop motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The part is supplied new and tested before shipping. It is not a main laptop battery and will not power the system.

Simple Swap with Basic Precautions

Installation involves opening the laptop chassis, locating the coin cell on the motherboard, and swapping the old unit for the new one. Polarity must be observed to avoid damage. The main risk is static discharge or damaging fragile ribbon cables during disassembly. No soldering is required for this socketed type.

Confirm Motherboard Compatibility First

Verify that your specific MSI CX640 motherboard uses a standard coin-cell CMOS battery before ordering. Some revisions may use a different connector or form factor. Check the existing battery markings against the replacement to ensure a match. This item is a single battery only; no tools or adhesives are included.
