Product information

Description

Lenovo FRU04Y1785 (Guinness1RTC) is a replacement real-time clock (RTC) battery module designed for compatible Lenovo systems. It maintains the system clock and critical BIOS/UEFI settings when the main power source is disconnected, allowing the device to retain correct time and configuration after power loss. This module is intended for service, repair, and maintenance of laptops and desktops that accept this form factor and connector type.

Advantages

This RTC battery module provides reliable timekeeping and low-power standby operation to preserve BIOS settings and hardware configuration data. It is sized and designed for straightforward installation in systems that require a dedicated RTC power source, reducing risks of CMOS reset and associated boot or configuration issues. The unit is a direct-replacement style component that helps restore proper system behavior without altering other hardware.

Suitable for

  • Repairing laptops or desktops that have lost BIOS settings after power removal
  • Replacing a depleted RTC battery during scheduled maintenance
  • Service environments where restoring correct system time and configuration is required
  • Technicians performing component-level refurbishment or board-level repairs

Key specifications

  • Function: real-time clock backup power module for preserving system clock and BIOS settings
  • Form factor: compact RTC battery module designed for internal mounting on compatible logic boards
  • Power source type: dedicated low-current backup cell(s) suitable for long-term standby retention
  • Operating role: maintains CMOS/BIOS settings and real-time clock while main power is removed

How to use

Power off the system and disconnect it from any external power sources before replacing the RTC battery module. Access the motherboard area where the original RTC module is located following the device manufacturer's disassembly instructions. Remove the depleted module carefully and install the replacement in the same orientation and connector position. Reassemble the system, reconnect power, and verify BIOS/UEFI retains date, time, and configuration settings. If needed, enter BIOS to adjust date and time after installation.

Usage recommendations

Handle the module with anti-static precautions and avoid shorting contacts. Use this replacement only in systems specified to accept this type of RTC module; check the device service documentation for compatibility and installation instructions. Dispose of the depleted battery module according to local regulations for battery recycling.
