Luvkitty had started a topic in the Vista section on how the various methods of shutdown (hibernate, standby, shutdown) affect her pc and whatever security scans she might be running. Usasma et cie answered her questions quite helpfully, but suggested I start another topic here for XP (I have SP3).
I am asking these questions in very general terms, and not relating to whether there may be malware already installed or application problems, etc.
What are the relative merits of standby vs. hibernate vs. shutdown? What are the relative problems? I am talking about when one is ending a session on a theoretically healthy pc. I understand that pc's as currently designed do not use nearly so much energy as they did 5 or 10 years ago, so setting a pc on low power usage options is not really necessary. Do standby or hibernate options pose a security risk, if the pc is left on for longer than necessary (say a few hours or a day)?
