The CMOS Bios Battery Replacement & Test [CBBRT] is a professional technical service designed to restore the foundational system settings and timekeeping functions of your computer. When a motherboard’s complementary metal-oxide-semiconductor (CMOS) battery fails, the system loses its ability to retain vital hardware configurations and real-time clock data when powered off. This service resolves persistent boot errors, reset clock issues, and hardware initialization failures by installing a fresh, high-quality cell and validating system configurations.
Service Type: Hardware maintenance, component replacement, and system configuration.
Purpose: Resolving system time desynchronization, lost BIOS/UEFI configurations, and startup configuration prompts.
Outcome: Reliable system boot behavior, consistent time tracking, and preserved hardware performance settings.
Service Requirements: The complete computer system must be provided for service. Any custom or proprietary BIOS passwords should be supplied to ensure setup access.
Assessment Notes: Final pricing and turnaround times depend on diagnostic findings and parts availability.
** Notice: This service does not include laptops or similar devices where complete disassembly is required **
In-Store Advice: Guidance on repair options, upgrade suitability, data recovery expectations, and hardware compatibility.
Local Support & Advice: Assistance with ongoing maintenance, performance optimisation, and personalised service recommendations.

Our battery replacement process goes beyond simply swapping out a coin cell. Technicians safely open the chassis, isolate the battery socket without stressing the motherboard, and clear any corrosive residue if old cells have degraded. Following the physical installation, we update the BIOS firmware to the most stable revision if necessary, reconfigure your specific storage and boot priorities, and perform complete power-cycle testing to confirm data retention.
Component Replacement: Installation of high-grade, long-life lithium coin cells matching exact manufacturer specifications.
Hardware Diagnostics: Voltage verification of the old and new cells alongside board-level power circuit checks.
System Stabilization: Re-establishing proper Unified Extensible Firmware Interface (UEFI) and BIOS parameters for stable system communication.
Key Features & Specifications
Service Scope: Physical replacement of the internal CMOS battery, precision voltage testing, and custom BIOS option re-entry.
Technical Capability: Component level swaps on complex desktop motherboards, space-constrained small form factor systems, and delicate laptop mainboards.
Tools & Methods: Digital multimeters for precision voltage verification, anti-static safety equipment, and specialized firmware configuration tools.
Supported Devices: Laptops, desktops, workstation towers, and compatible all-in-one computer systems.
