It should beep for missing RAM. A missing hard drive may instead
result in a message on the monitor screen.
Beeping is reserved for those occasions, when there is an expectation
that you cannot see the screen. If the BIOS thinks the screen is working,
then it'll put an error message on the screen instead. The missing
hard drive would mean writing the error on the screen. But missing
RAM would result in no video, hence it beeps for that one. So missing
RAM or a missing video card, are considered good reasons to beep.
I'd check the wiring from computer case speaker to motherboard.
On some prebuilt computers, there is a piezoelectric device on
the motherboard, instead of a speaker. And because there is no
wiring involved, it would be less likely that it would stop working
due to a wiring problem.
If the CPU is broken, or removed from the socket, or the
BIOS flash chip is corrupt or erased, those are reasons it
won't beep too. (Beeping requires BIOS code to be executable,
as far as I know.)
Only if the computer, was known working and completely normal,
would you have an expectation of getting the beep when the RAM
is removed. If something else is broken as well (say a dead
power supply), all bets are off. Listen for fans spinning,
as partial proof of a working supply.
On one BIOS I've heard of, the manufacturer modified the beep
feature, because the BIOS was beeping once for every USB
device plugged in. Their "workaround" was to disable beeping
altogether, and it is unclear whether that motherboard can
beep, when you pull out the RAM. It would depend on which
BIOS version is being used.
The best motherboards, are the ones that include alternate
mechanisms. Some Asus motherboards have "Vocal POST", where
an error message is sent through the computer speakers. A
couple other brands of boards, have port 80 status displays,
and can show what routine the BIOS is currently executing,
by means of a two digit code. Some prebuilt computers, have
a four LED display, which does something similar. So there
are some alternative debugging methods for those systems.

Forgetting to plug it into a power socket (that is powered).

Multiple causes... including overclocking to the point where it CANNOT
physically POST will do it.
If that's the case, reset the CMOS and see if it can get to a POST state
again.
