Do you know you have to push a breaker all the way to the off position to reset it before turning it on? A tripped breaker looks like it is still in the on position. Try switching the breaker for those receptacles to the off position and back on.
These receptacles may be fed from a GFCI receptacle upstream. Go push the reset on any GFCI receptacles you may have in a bath or etc that may be feeding the bedroom receptacles. When you checked for AC did you use a meter? Try metering the hot side of the receptacle to the ground (It's the shorter of the two slots). If that's hot, you have an open neutral perhaps. Try metering first for voltage from the neutral slot(the longer of the two slots) to ground and then check for continuity between them after verifying no voltage is present. Since the ground and neutral meet back at the panel, this would verify the neutral. Keep us posted on this will you? Luck, Kizmet
