DBTLAP CMOS Battery for MSI Wind U100

SKU CH-PQZ1-SRGN9

Lithium CMOS battery replaces the BIOS RTC cell on MSI Wind U100 laptops

  • Battery TypeLithium
  • Direct replacement for MSI Wind U100 motherboard
  • Lithium chemistry provides stable CMOS power
  • Single unit includes one RTC battery
  • Tested before shipping for reliable operation
  • Fixes BIOS time loss from faulty cell

Direct replacement for MSI Wind U100

This lithium CMOS battery is built to fit the MSI Wind U100 motherboard and restores the real-time clock and BIOS settings when the original cell fails. It is intended for owners of that specific netbook who need a tested, new replacement rather than a generic alternative. Buyers with other laptop models cannot use this part.

Tested lithium cell ships ready to install

The battery arrives new and pre-tested so it holds charge immediately after fitting. Lithium chemistry provides stable voltage for the RTC circuit with negligible self-discharge during normal operation. No additional power draw or thermal load is introduced beyond the microampere levels typical of CMOS circuitry.

Single battery in the package

The box contains only one CMOS RTC battery; no tools, cables, mounting hardware or software are included. Installation requires opening the chassis and swapping the cell, so users without disassembly experience may prefer professional service. The bundle does not add any diagnostic utilities or firmware updates.

Questions about this item

How do I install the CMOS battery in my MSI Wind U100 and what step is often missed?

Open the chassis, locate the coin-cell holder on the motherboard, remove the old cell, insert the new lithium battery with the positive side facing up, then reassemble and reset the BIOS time and date.

What maintenance or replacement will this CMOS battery need later?

The lithium cell will eventually deplete; when the system clock drifts or BIOS settings clear at startup, swap in a fresh CMOS battery.

What limit appears first under sustained use of this CMOS battery?

The battery's finite capacity means the RTC circuit will lose backup power after several years, causing clock drift and BIOS reset.
