[QUOTE="gibman, post: 998705, member: 25430"] regarding the automatic power switch. I used to have one of these USB enabled ones - although some other el cheapo brand. For this to work reliably you will need the USB port to power down when turned off / suspended. Some motherboards always output 5v to the USB port, which renders the power switch unusable. Some motherboards offer a BIOS setting / physical jumper that needs to be activated in order to enable/disable "always power on USB" feature. What I found to be more bulletproof is to buy an intelligent master-slave power switch that monitors the current power drain on the master. If the power consumption gets below some defined threshold, like 5 watts, then the power switch considers the main device as turned off. It then turns of the slave outlets too. Some power switches even has a way of defining the watt threshold which can come in handy with those ATOM based htpc rigs as they consume almost nothing. So my advice: get a power switch without USB, but instead one with a user definable threshold for minimum watt. I think its around 10 eur or something. Another thing is, some TV's do not like to get power switched off (live it happens when connected as a slave on the power outlet). example: in my livingroom I have a sony LCD TV, it doesn't mind at all that power is being turned on/off during htpc off/suspend. bedroom panasonic plasma doesnt like being turned off. when being turned on again, I have the HDMI handshake stuff being done => half screen issue etc. (no, havent tried new mp version) but if I run the plasma on its own power socket and just use the remote to turn on/off the TV, then no problems. another thing is; I wouldn't want a plasma TV to automatically power itself on when htpc decides to turn on. can u imagine being at work when your TV turns on .. nice burn in when u get home :) and htpc just resumed as it wanted to do some win updates :) I do like to put the AVR and subwoofer on as a slave device, same for LCD tv's ofc. if your rig is acting as a tvserver as well, then matters are further complicated as it has a lot more automatic wake up cycles. how much do u want to turn on automatically in these situations ? the power switch obviously cant differ between what caused the wakeup :) but for multiseats it rocks. /gibman [/QUOTE]
