  A combined search for the Standard Model Higgs boson with the ATLAS detector
at the LHC is presented. The datasets used correspond to integrated
luminosities from 4.6 fb^-1 to 4.9 fb^-1 of proton-proton collisions collected
at sqrt(s) = 7 TeV in 2011. The Higgs boson mass ranges of 111.4 GeV to 116.6
GeV, 119.4 GeV to 122.1 GeV, and 129.2 GeV to 541 GeV are excluded at the 95%
confidence level, while the range 120 GeV to 560 GeV is expected to be excluded
in the absence of a signal. An excess of events is observed at Higgs boson mass
hypotheses around 126 GeV with a local significance of 2.9 standard deviations
(sigma). The global probability for the background to produce an excess at
least as significant anywhere in the entire explored Higgs boson mass range of
110-600 GeV is estimated to be ~15%, corresponding to a significance of
approximately one sigma.
