That's why a simple reboot doesn't always work: the power is only interrupted for an instant, not necessarily long enough for memory to clear and everything to be reset.<br /><br />The time interval is fairly arbitrary; it just needs to be long enough to ensure everything is dead. Thirty seconds is more than long enough, and most people will manage to wait at least half that time, which should be sufficient.<br /><br />And, of course, if there's a backup battery, then all bets are off.NomadUKnoreply@blogger.comtag:blogger.com,1999:blog-38548109.post-43504605601140858282009-11-27T23:39:44.238+00:002009-11-27T23:39:44.238+00:00@Graham: not forgetting to wait 30 seconds, of cou...@Graham: not forgetting to wait 30 seconds, of course! Is there any technical basis for this seemingly arbitrary interval? Surely, if the power is cut, it's cut, there's no 'in-between', is there?Douglashttps://www.blogger.com/profile/03345758492182779923noreply@blogger.comtag:blogger.com,1999:blog-38548109.post-44254927587488228092009-11-27T20:15:11.557+00:002009-11-27T20:15:11.557+00:00Have they tried switching it off and on again?Have they tried switching it off and on again?Graham Ardenhttps://www.blogger.com/profile/00979231435522353662noreply@blogger.com
