MSI Wind U230 CMOS replacement

This lithium CMOS battery is built for the MSI Wind U230 laptop motherboard. It restores the real-time clock and BIOS settings when the original cell has drained. The part is a direct-fit replacement, not a main laptop battery. Install it to fix date resets and boot errors caused by a dead RTC cell.

Lithium coin-cell limits

A single lithium coin cell holds enough charge to keep the RTC running for several years under normal use. It cannot power the laptop itself and will not fix faults unrelated to the CMOS circuit. The battery is tested before shipping but has a finite shelf life once installed. Extreme temperatures can shorten its useful span.

Upgrading from a drained original

Swap this in when the system clock loses time, BIOS settings revert on every boot or the machine refuses to POST because of a checksum error. The jump is worth it if those symptoms appear and the board is otherwise sound. It will not help if the fault lies in the charging circuit, the RTC chip or a damaged motherboard trace.

Questions about this item

Which CMOS battery version fits the MSI Wind U230?

This DBTLAP lithium cell is built to match the original RTC battery used in the MSI Wind U230 motherboard.

What does the lithium chemistry mean once the battery is installed?

It supplies steady 3 V power to keep the real-time clock and BIOS settings alive while the laptop is off.

What connector standard does the battery use and what does it limit?

The two-pin JST-style lead plugs straight onto the motherboard header, limiting installation to boards with that exact socket.
