and turn off WOL or Wake On Lan.
The problem I am facing is a rather annoying one, as probably the majority of the computer-related nuisances bringing people on forums like this. I have decided to create a new thread after having perused a dozen or more discussions on similar topics, that is, related to the sleep feature, without finding the right answer. In a nutshell this is what is happening: About a month ago, my computer has started to wake from sleep without any obvious reason. In the event viewer these awakenings can be followed under the Power-troubleshooter event in the Windows logs. Invariably the source is marked as unknown. I tried to get more information using the lastwake command prompt, but to no avail at all, the answer it gives equals to unknown. The time of these awakenings is very different, it is not a fixed hour or minute of the day. For example: 04:08:25, 12:37:06, 04:18:35, 02:27:25, 12:05:40, 02:03:44, 12:43:54, 12:13:32 etc. Usually a couple of hours pass between the events, but there are days, when it wakes almost hourly. I will try and upload a screen capture of the Event viewer so as to show you the event sequence. I have already gone through all the possible settings that could be responsible of this problem, but it is still there. As a makeshift solution, I have adjusted two minutes for the computer to go to sleep if no mouse or keyboard event. I had in addition to recur to a small program that lets me quickly enable or disable the sleep feature with a single click from the tray, similar to Caffeine but better, more flexible (DontSleep). It all works fine now, the annoyance is considerably reduced, but still I haven’t got the slightest idea as to the wake source. Could it be a virus that wakes the computer in my absence in order to break into the system and get my bank details or something of the sort? Any hint would be appreciated.
