Description

Replacement internal RTC battery for Lenovo laptops, model 01HY789, designed to maintain the real-time clock and BIOS configuration when the primary battery is removed or fully discharged. This internal coin-cell style battery is intended specifically for compatible Lenovo laptop systems where preserving timekeeping and BIOS settings during service, storage, or main battery replacement is required. The product fits into the motherboard RTC/battery holder and acts as a dedicated power source for CMOS memory and clock functions.

Advantages

Its form factor and design match the internal connector and mounting requirements of supported Lenovo models, enabling straightforward replacement without altering system hardware. The battery supports consistent CMOS retention, which helps avoid repeated BIOS setup and prevents issues related to incorrect system time.

How to use

Power down the laptop, disconnect the main battery and AC adapter, and follow the manufacturer's service instructions to access the internal RTC battery location on the motherboard. Carefully remove the old RTC battery or module from its holder or connector and install the Lenovo 01HY789 replacement, ensuring proper orientation and secure connection. Reassemble the laptop and reconnect the main battery and power; verify system time and BIOS settings and, if necessary, adjust the BIOS configuration after installation.
