  • Battery TypeLithium
  • Keeps BIOS settings accurate with a fresh lithium CMOS cell
  • Direct replacement for the Sony VAIO VGN-NS30E/S motherboard battery
  • Tested before shipping so it works on first install
  • Includes one ready-to-fit CMOS battery in the pack
  • Restores system clock and hardware configuration after old cell fails

CMOS battery for Sony VAIO VGN-NS30E/S

This lithium CMOS battery replaces the RTC backup cell on the motherboard of the Sony VAIO VGN-NS30E/S laptop. It keeps the system clock and BIOS settings alive when the main power is removed. The part is new and tested before shipping. It is intended for owners of this specific model who need to restore correct timekeeping and configuration retention.

Fits the motherboard battery holder directly

The cell slots into the existing CMOS socket on the board, requiring no extra cables or adapters. Installation frees the system from reset errors, incorrect dates and lost BIOS parameters caused by a depleted original battery. No additional power components or chassis modifications are needed for the swap.

Replaces a dead or failing original CMOS cell

The upgrade is worth it when the laptop shows symptoms such as clock drift, checksum warnings or BIOS settings reverting to defaults after shutdown. It does not address main battery runtime, charging issues or any power delivery beyond the real-time clock circuit. Buyers needing a main battery replacement should look elsewhere.

Questions about this item

How long does the CMOS battery typically last before the system clock starts losing time?

The lithium CMOS battery generally maintains BIOS settings and the real-time clock for several years; lifespan varies with motherboard current draw and ambient temperature.

Does the battery generate noticeable heat or noise during continuous operation?

No, a CMOS battery is a passive lithium cell that produces no heat or noise while supplying the tiny standby current needed for the RTC and BIOS memory.

What connector does the battery use to attach to the VAIO VGN-NS30E/S motherboard?

The replacement cell comes with the same two-pin wire harness used on the original Sony VAIO VGN-NS30E/S board, so it plugs directly into the existing CMOS header.
