Confirm that your specific motherboard uses this exact CMOS battery model before ordering. Check the existing battery for matching voltage, physical dimensions, and connector orientation. Ensure you are comfortable opening the laptop chassis to access the motherboard. This part is intended for motherboard-level replacement only.
