[QUOTE="macwise, post: 1415337, member: 187838"] Here's the latest, last night, I set the PMU to shutdown at 1 am and wake at 5 am. Well it did shutdown when supposed to as I watched it do it, but when I went back this afternoon to check it, since I forgot all about it, it was shut down. I tried to start it again and the white LED came on and then nothing, I unplugged the PSU and checked the voltage, it was practically null, I unplugged it from the AC and waited a few mins. checked again and it was 19, I plugged the PSU back in and it started up and booted with no problem, this leads me to believe the culprits were the battery, which is now replaced and the PSU which was most likely failing and it just getting worse, at any rate I think it's time to replace the PSU. I am on it now, so I"m going to post before it shuts down again, I am looking very closely at the logs and trying to figure out why it shut down, I will post what I find as I find it. I think the best way to respond to all of your tips is in quote form so here goes. [B] Thanks so much for all the help and suggestions.[/B] [/QUOTE]
