My PowerBook with 1GB RAM easily gets a week of sleep time off a fully charged battery; I don't think I've rebooted it _once_ in the last 2 months, I just leave it sleeping in my bag the whole time. Sony must be doing something wrong, because there's easily enough power in a single battery to keep RAM refreshed for a _long_ time. > Yes, for a few hours suspend-to-RAM is convenient but suspend-to- > disk is _reliable_ and _safe_. As to the safety issue, I have my Apple Powerbook configured to suspend to RAM, and if it gets critically low on battery I have the firmware set to resume it automatically and my scripts shut it down so I don't lose data. Suspend-to-RAM when implemented properly _is_ reliable and safe, but it seems like a lot of hardware manufacturers get it wrong.
