How to use
Power down the system and disconnect external power sources before accessing the motherboard. Locate the CMOS coin cell holder, gently remove the old cell using an appropriate non-conductive tool if necessary, and insert the new lithium coin cell with the correct polarity. Reassemble the device, reconnect power and verify BIOS settings and system time; adjust as required in the BIOS setup interface.
