Direct Replacement for Gateway NV78

This CMOS RTC battery is a direct replacement for the Gateway NV78 laptop motherboard. It is a new lithium coin cell intended to restore BIOS settings and system clock accuracy. The part is designed for motherboard installation, not as a main laptop power source. It suits owners of the specific model needing a tested, ready-to-fit unit.

Simple Motherboard Swap

Installation requires opening the laptop chassis to access the motherboard socket and exchanging the old cell. The package includes a single battery that has been tested before shipping. Common issues arise if the connector orientation is reversed or if the retaining clip is damaged during removal. No soldering is needed when the original uses a standard plug-in holder.

Restores BIOS and Clock Function

The lithium cell provides the low current needed to keep CMOS memory alive while the main power is off. It comfortably handles normal standby periods and cold boots. Capacity will eventually deplete after several years of continuous use, at which point date, time and BIOS settings will reset again. Not a substitute for a failed main battery pack.

Highlights

  • Replaces faulty CMOS battery on Gateway NV78
