hi, in an old pc i have had second hand for five years or so it says it
the
instruction booklet that it has a lithium battery in the system board can
be
replaced.

how would i know when this needs to be replaced please? will the whole
p.c.
just stop working? thanks



You replace the battery when the clock starts to lose time or the PC
complains at boot that the CMOS settings are incorrect and when you correct
them they're lost again when the computer is powered off.
