why, tell why first. context matters, for sure.
but you can remove the coin cell on any PC made (some tiny notepads excepted, have none see why below)
that resets all PCs made, and will not erase
passwords.
PW are not STORED THERE, NVRAM CMOS.
ever heard of asus.com?
there huge web site, support??
the real name is
ASUS VivoBook X540LA
asus has no service manual; only user man. and has no such topic in the users manual
as a rule (thin notebooks)
if the huge battery on that just snaps off the bottom in 5 seconds
yours don't.
it's no longer there, that means it is now deep inside and thin.
and that means most PCs like that , have no coin cell.
that means you must unplug the inside flat black battery
push power for 10 seconds (button) release then wait say 1/2 hour the put the battery back in.
now the NVRAM CMOS is reset.
does that answers your question?
here is your big battery, remove this , per above.
and if BIOS NVRAM CMOS resets then good.
if NOT there is a coin cell hidden deep in side, fact is.
the joy of thin notebooks 101
