Why can I put my XPi on standby mode?
There are several factors which might prevent your laptop from going into standby. Usually it’s a software program or a hardware device that is preventing the standby process from initiating. I’ve found on WIndows 98SE that if you install Internet Connection Sharing on your particular laptop, it will prevent you from going into standby or suspend-to-disk (I have no idea if this applies to later Windows versions with ICS). I know of no workaround for this besides uninstalling ICS. Microsoft also has a utility available called Power Management Troubleshooter Tool (article #Q185949 — its filename is pmtshoot.exe) for Windows 98 that can tell you what the culprit may be.
