  It is currently believed that the ``standard'' accretion disk theory
under-predicts the observed X-ray luminosity from Soft X-ray Transients (SXT)
in quiescence by as much as 4 to 6 orders of magnitude. This failure of the
standard model is considered to be an important argument for the existence of
the alternative mode of accretion -- Advection Dominated Accretion Flows (ADAF)
in astrophysics, since these flows allow a much higher level of X-ray emission
in quiescence, in agreement with the observations. Here we point out that, in
stark contrast to steady-state standard disks, such disks in quiescence (being
non-steady) produce most of the X-ray emission very far from the last stable
orbit. Taking this into account, these disks can accommodate the observed X-ray
luminosities of SXTs rather naturally. Our theory predicts that Fe K-alpha
lines from standard accretion disks in quiescence should be narrow even though
the cold disk goes all the way down to the last stable orbit.
