There are some hacks around to get it up to 10.7.5. Install Lion in the standard way, boot into your old OS, delete the 'PlatformSupport.plist' from your freshly installed Lion partition (it's in 'System/Library/CoreServices') - then Lion will boot just fine :-)

There are two different power supplies for Mac Minis. A1103 PPC uses 85W, A1176 Intel uses 110W. Make sure you have the correct one. If so, there is a last ditch effort to remove a bad resistor on the power section of the board. I have revived 3 minis this way. This explanation is incomplete, but if you find the bad resistor and remove it, it will in fact turn on. http://forums.macrumors.com/threads/2006-mac-mini-possible-fix-for-no-power-to-logic-board.1513809/ http://forums.macrumors.com/attachments/...-2006-shorted-cap-jpg.415700/

Really? Model A1176 did NOT use magsafe connector. When you have a mini with a short on the motherboard (presumed dead), the 18v 110W power supplies simply shut down internally. Simply disconnect it from the mini, unplug it from the wall, and it resets itself. It should then work fine in the other known good mini (assuming you are not mixing 85W and 110W power supplies).

Sounds like you forgot to connect the 2pin connector on the front next to the battery when you lower the drive tray down. That always causes the fan to run loud. I forget to reconnect it all the time (upgraded 15+ minis already).

Hello, Most likely it is not the power adapter if it is the original. The A1176 needs a 110W power supply. The PPC 85W supply will not work. I have upgraded the CPU on over 15 core minis with great success. I had two that never powered on and searched high and low for the fix. THIS IS IT: There are several banks of capacitors on the top and bottom of the motherboard. By hooking a 5v power supply up, you can use your finger to find the faulty one as it gets hot. I use a 110v iphone charger and an old keyboard cable to make my 5v leads. Ground the black wire onto the outside USB frame. Use the red wire to touch the sides of some of the banks and if one of the caps gets hot, just pry it off. BAM, both of the motherboards were fixed. Found it after googling quite a while. Here is a pic from the site, and my own motherboard afterwards (note the x on the chip because I thought the motherboard was dead). My faulty cap was the 3rd one from the edge on the top side of the board.

Since the resurrected motherboard I have is going into a cube case and was missing the original heat sink, this alternate was held in place with zip ties. I just used small zip ties about 3-4 inches long. Ran one down from the top then back up from the bottom... and used a second one to bridge across. Add two more for the other set of holes. Not spring loaded, but holds it on there with no problem. Update (11/15/2017): Zip ties with original springs:

I swapped min Core SOLO 1.5 up to a 2.33 T7600 over a year ago, no problems. A good source for a T7400 would be any dead white iMac (intel with isight, 2006/2007 era). 3Gb ram is the max available: http://www.123macmini.com/news/story/729...
