I've been using my standby mode quite awhile, but lately it seems to act weird. I click on "Standby", the pc does its thing and you can tell of the silence of the pc. Unbeknownst to me after awhile as I am busy doing things in the apartment, I hear the pc is running. Now in the past, it would always be off until I reboot out of standby. I turn on the pc and there is a message that says something like "others may be on ..and may lose their data...are you sure you want to shut down??" I am the sole user of this pc...so what is that all about. ..this only started recently. I have never gotten that message before after putting my pc in standby mode.
