Intel MB440LX manual Back-up Battery, Varning

Back-up Battery

The lithium battery on the system board powers the real-time clock (RTC) for up to 10 years in the absence of power. The RTC contains 256 bytes of general purpose RAM that stores the system BIOS configuration information, clock registers, and general purpose control registers. When the battery starts to weaken, it loses voltage, and the system settings stored in CMOS RAM in the RTC (for example, the date and time) may be wrong. Contact your sales representative or dealer for a list of approved replacement devices and available service.

▲WARNING

If the system has been running, any installed processor and heat sink on the processor board(s) will be hot. To avoid the possibility of a burn, be careful when removing or installing system board components that are located near processors.

The following warning and translations are required by specific certifying agencies to be printed immediately adjacent to the procedure for removing the real-time clock.
