Hi Guys, I just signed in, because I have a big trouble with my machine, and it seems, no professionals could help me. Around a month ago, my machine started act weirdly : shutting down, instead of go to sleep mode. A few days later, it did not want to start, so I sent it a service centre. They sad, a few days later, no problem with the machine at all, and sent it back to me. Actually, there was really no problem with it for around a week, then, again, won't start. This morning, I've plugged it off the wall, and left. After I've got home from the work, tried it, and now, it works. I've checked the diagnostic LEDs during a failed boot, and everything seems normal, then **** down, then the OTA and OTB LEDs lights up for a second and thats all. I think it is a PS problem, but before I'm gonna sped 200 EUR for a new PSU, I would like to be sure... Have any of you every experienced the same?
