Me parece que es una buena opción para remplazar la CMOS que tiene de fabrica, mi laptop es una Lenovo Thinkpap T430, previamente al usarla, tenia la problemática de que este se apagara sin razón sin retener la fecha y la hora, de momento veré cual es el rendimiento de esta CMOS, 📝 Lo compre con el proveedor RF Official entregado por la paqueteria de AMAZON, llego perfectamente protegido en una caja grande a pesar de que el producto es pequeño, llego en tiempo y forma según lo programado 👍🏳
