The model II takes a few seconds to fully boot up and then turn the audio on. Make sure you are waiting the right amount of time.  
The Model 1S takes a few seconds to fully boot up and then turn the audio on. Make sure you are waiting the right amount of time.  


Secondly, if you do reset the system for some reason, be sure to wait a full two or three seconds between turning it off and turning it back on.

=== Fan Noise  ===
<section begin=heat/>
Q: The fan in the Power Stand comes on when I strike a chord on my Guitar. Is this normal? A: Your unit is functioning properly - no problem.
 
The fan in the Model II Power Stand comes on when the input signal level goes over a certain limit, regardless of what the internal temperature of the unit is. That way, the unit never gets too hot to where a fan needs to be on constantly.
 
Whatever you do, please don't cover up the fan port.<ref>MikeZ-at-Bose [http://bose.infopop.cc/eve/forums?a=tpc&f=7521050644&m=8071027174&r=7091047174#7091047174 Model II Fan Noise]</ref>
 
There is a Firmware Update that addresses the fan behaviour. See: [[L1® Model II Power Stand Firmware Updates#Fan_Behavior]]

== Noise During Shutdown ==
Q: When I turn off the Model II there is sound like flatulence. Is this normal?
 
A:
:Over a year ago we implemented an improvement which allowed the system to better withstand extreme low voltage conditions caused by brown outs etc. Units produced prior to this change were quiter during the power down sequence.
 
:Note: This noise is only present when the system is being turned off following use. For instances where this subtle noise is objectionable you may remove the Cylindrical Radiator loudspeaker and disconnect the Speakon cable of the B1 before powering down the system.
 
:For anyone that is experiencing noise during power down we want to assure you that your system is working properly. Also, there is no reason for customers with older power stands to be concerned with upgrading as any potential issues would have surfaced by now. <ref>Neil-at-Bose [http://bose.infopop.cc/eve/forums/a/tpc/f/76010377/m/948107242?r=207101852#207101852 Modell II Shutdown Noises August 3, 2009]</ref>

You can certainly run the L1 with all, some, or none of the speakers connected. With no speakers connected it will happily serve as a big power supply for the T1. You are in no way risking damage to the unit by doing this.<ref>MikeZ-at-Bose talks about [http://bose.infopop.cc/eve/forums?a=tpc&f=3976055944&m=2261013484&r=7911053484#7911053484 Using the L1™ Model II Power Stand without any speakers attached]</ref>
