The main cause, as explained, is the battery (CR2032).
You need to change it.
It causes also BSOD.

The OP did mention that he tested the CMOS battery and it read above 3.0VDC.

Now it could be the battery holder that is defective. You need to check
that Vbb is getting to the timekeeper - and someone kindly posted a ink
to the schematics so the OP can check that out now more easily.

This Dell Inspiron N5110, which has Windows 7 Home Premium installed,
was given to me because upon startup it would BSOD with a
REGISTRY_ERROR. That was resolved with a system restore but I noticed
another problem which has me puzzled. The system time does not advance
when the unit is turned off. I went into the BIOS setup and noticed
that within the time configuration, the seconds were not ticking. Once
the machine is booted into Windows, the automatic time synchronization
will eventually set it to the correct time and it stays that way until
it's powered off. The CMOS battery measures above 3 volts in circuit
and all the other BIOS settings are saved when the machine is off. I
tried temporarily removing the battery to reset the BIOS and the
result was that the time reverted back to several years earlier
however the seconds were ticking normally. I entered the correct
time/date and restarted the computer and all was well. I turned it off
for a while and then powered it on again and entered the BIOS setup.
The time was stuck again and the seconds were not advancing. It seems
to me that no matter what condition the Windows operating system is
in, it shouldn't be able to interrupt the time function when the set
is powered off. I tried updating the BIOS to a newer version but that
just crashed the machine. (Fortunately it didn't brick the machine). I
found other users complaining about the frozen clock issue but as yet
have found no solution. Here is an example of a similar complaint.

Anyone have any ideas what is causing this suspension of time?

Thanks for your reply.
