HTPC (ion-330ht) boots by itself - Glitch - 2009-12-15 Hello, Usually I can find the answer through search and therefor I dont post that often. But this issue is just to weird and I dont know what to search for. The thing is, I have an ASRock ION-330HT BD and I have installed XBMC Live on the HDD. As some of you might know there currently arent any Linux drivers available for the built in IR reciever of the ION-330HT. I have ordered an external IR receiver but at the moment I'm using only a USB mouse. In other words, if I want the HTPC to boot I have to walk over there and manually press the start button power button. Now this is where it gets weird. I have experienced a couple of times that the HTPC has booted without me pressing the power button. I'm 100% positive I had shut it down using the shutdown function of XBMC (shutdown action is set to shut down and the power light goes out). Now already a couple of times I notice some time later (could be hours up to a day) that the HTPC has booted up again. I must be missing something, how is this possible? Only things I could think of myself is that the HTPC is somehow still responding to the signals of my Harmony One remote control, but then again. The IR reciever doesnt work and the system is shut down. Another idea was wake-on-lan, but again. The system was completely shutdown. I feel like such an idiot for not figuring this out. It would be nice if someone could point me in the right direction how this is possible. - rectifyer - 2009-12-15 Maybe there was a power spike and the motherboard thought it should turn itself on? There should be a setting in the bios to control what happens in that situation. Normally i thought it would only turn on if it was previously on, but might be something to look at at least. - biggles - 2009-12-15 Don't worry. You are not alone. My HTPC also restarts without anyone interacting with it. Most noticeable is it during the night. When I get up in the morning the HTPC is on even though it was off earlier during the night... Really strange! - horserider - 2009-12-15 My Asrcock 330HT does reboot itself as well. - XBMC_Lover - 2009-12-15 Hi Guys, i had the same Problem. It turned out, that it was related to my Wireless USB Keyboard. I discovered, that this mostly happened when i turned on my TV. Then from time to time the LED of my USB Receiver for that keyboard flashed as it does when receiving keypresses or mousemoves. Whis this flashing the Asrock turned on. By pressing a key on the Keyboard NEVER turned on the ASROCK and the USB receiver also does not flash when pressing a key on the keyboard when off. As i turned off my TV the ASROCK stayed off. I moved my ASROCK 100cm away from my TV and now it stays off. I also wrote to Asrock regarding this problem, with no solution. Maybe you have similiar issues? PS: Asrock told me that Power on by Keyboard is not supported - luna_s - 2009-12-16 i don't have this problem, as i turn it off at the wall..... - Glitch - 2009-12-16 XBMC_Lover Wrote:Hi Guys,This seems to be more explainable, since you have a receiver plugged in that can receive signals. It could be that the USB receiver for the keyboard is catching the signals from the remote of your TV. This can not happen in my case as there is no working IR receiver at the moment. I will try unplugging the USB mouse though. Perhaps this is somehow triggering the automated boot. I still think it's strange as I have the system completely powered off. - XBMC_Lover - 2009-12-16 Glitch Wrote:This seems to be more explainable, since you have a receiver plugged in that can receive signals. It could be that the USB receiver for the keyboard is catching the signals from the remote of your TV. To speak Clear: my USB Receiver is an RF Receiver 2.4 GHZ and when testing i did not use *any* Remote. All i was doing is standing beneath my Asroock and watching the LED of the USB Receiver. When it flashed, the Asrock waked up and i powered it off with the Power button. Few minutes later it powered on again. I turned off my TV and the Asrock also stayed off. BTW: This USB receiver did not power on my former HTPC (MSI MEdia Live) without interaction. - Glitch - 2009-12-16 Well my guess is that ASRock is wrong in saying their product does not support power-on-by-mouse/keyboard. I have disconnected my mouse and will post my findings here. If the system does not boot by itself anymore this is clearly the cause. Next step will then be, how to turn of this unwanted behaviour ... - Glitch - 2009-12-16 Just came home from work and the system had booted up without the mouse attached to the USB port. Doesnt look like wake-by-usb is the reason for this behaviour. This is getting really annoying. - Harry Muscle - 2009-12-16 XBMC_Lover Wrote:Hi Guys, Sounds like electromagnetic interference, nothing to do with a power on by keyboard feature. You mention that moving the computer away from the TV or leaving the TV off prevents the problem ... which also removed electromagnetic radiation produced by the TV. Looks like the Asrock 330 might not have the best shielding on it. Try wrapping it in a few layers of aluminum foil, making sure the foil is touching something grounded. If that also fixes it, then its for sure a electromagnetic interference issue and poor shielding on the PC.

My statement about the power on by keyboard was meant ironic. I also think it has something to do with interferences, although it never happend without the USB receiver. I also think Asrock knows about the problem, as the asked me to remove ALL USB devices. - Harry Muscle - 2009-12-17 XBMC_Lover Wrote:I know this. My statement about the power on by keyboard was meant ironic. I also think it has something to do with interferences, although it never happend without the USB receiver. Sorry, didn't catch the irony ... I wonder if the interference is somewhere in the USB circuits and any connected USB cables are acting like antennas picking up the interference and channeling it straight to the sensitive circuits. Try wrapping the cable in foil ... that might help.

Then again I have no devices attached to it and the IR receiver does not work ... The only thing attached to it is a network cable. Code: xbmc@XBMCLive:~$ cat /proc/acpi/wakeup Doesnt look like any of these devices is causing it too boot out of itself ... I wrote ASRock about it and this is what they answered: Quote:Hello, |
