Again don't expect power events to be 'clean'. They won't be. Despite claims to the contrary, a decent UPS will protect you from most events: they switch to battery at both low and high voltage within milliseconds. They do work: they typically even include insurance on machines plugged into them. It's usually not a big deal on Linux, but may be difficult to step your wife through "e3fsck found errors, please log in as root and run e3fsck manually". but then, change 'e3fsck' to 'chkdsk' and its the same basic thing. Like Windows, most of the time Linux will be fine from an expected shutdown. There will always be a risk with any hardware that a power cycle will be mistimed and catch you mid disk write. > > I fully understand that power spikes, lightning strikes, etc. are an > entirely different issue.

Thanks again. again, you will get spikes/dropouts when a car or tree or wind hits a power line, or a squirrel plays in a substation, etc. In almost all cases a UPS will protect you. It may even act like a giant fuse and protect you that way. Many 'surge suppressors' suck: they are a simple MOV across the line and the MOV has a limited lifetime and will give no warning when it has used up its useful life. It will just cease to protect you... a decent UPS will include a proper surge suppressor not a fifty cent MOV. -- snarlydwarf ------------------------------------------------------------------------ snarlydwarf's Profile: http://forums.slimdevices.com/member.php?userid=1179 View this thread: http://forums.slimdevices.com/showthread.php?t=80889 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
