Re: Power up problem
Hi Ronni, I tried that, even used a known good power cord (our plugs here are fused), no joy.

Re: Power up problem
Hi Paul, You could try Resetting the SMC (System Management Contoller) Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve • Shut down the computer. • Unplug the computer's power cord. • Wait fifteen seconds. • Attach the computer's power cord. • Wait five seconds, then press the power button to turn on the computer. http://support.apple.com/kb/HT3964 Cheers, Ronni 17 MacBook Pro 2.3GHz Quad-Core i7 “Thunderbolt 2.3GHz / 8GB / 750GB @ 7200rpm HD OS X 10.8.2 Mountain Lion Windows 7 Ultimate (under sufferance) On 22/10/2012, at 4:35 PM, Paul Willemse p...@thelink.to wrote: Hi Ronni, I tried that, even used a known good power cord (our plugs here are fused), no joy.

Regards, Paul There is a small battery on the motherboard which is used to maintain PRAM settings. If it is completely flat it can impact on the ability to restart. I'm not familiar enough with the Mac Pro to be able to give you reliable advice, but if history is anything to go by the battery will be a 3.5V half-AA Lithium type, and should be fairly easy to locate in a Mac Pro. I used to buy these from Dick Smith, but I haven't had to do so for many years so I don't know if they still carry them. Batteries Plus might be another source.

Re: Power up problem
Hi Ronni, Peter, Still no luck at all. I tried both suggestions and no change. I replaced the battery as it seemed low (just under 3V) and again no effect. Looks like I need to get to an Apple repair centre, there should be one here in Singapore, never needed one before... Thanks to both of you for the suggestions.

Power up problem
Hi All, Owing to some additional electrical supply being installed in my house I needed to power down my computers. All shut down properly, no indication of any problem. After the installation my older Mac Pro (about 6 years old) refused to restart or even try. The light above the power on button does not come on, nothing happens at all. Is there a battery or some other component that could cause this? Grateful for any assistance anyone can give.
