Gang,
OK, I was doing an easy mod on my V1, (or so I thought) moving the fan supplied power inside and installing a diode to turn the 10V off when the machine is off. Ok, I try and test to see if it works, No power at all. Try again, no power. Major angst. Remove everthing that ain't tied down tight. Again, no power. Test the power supply. 19V in at the ferrite but nothing else. Tested Q30, no 5V or 3.3V. Tested power going into the maxim chip where my vcore mod is. Tested pads R60,61. Nothing. 'Bout to have a caniption fit. Took a step back, a deep breath, and walked away for a few minutes. Came back, removed the cmos battery, wait a few minutes, put it back in. Powered up. green light comes on. Got the appropiate power at all check points. Screen lights up. Put processor and hard drive on. Hard drive spins but no activity light. I get a nice bright screen with nothing on it. It looks like a wiped clean windows desktop. Nothing else. OK, this narrow it down to either the processor or the bios, or both. And that's where I at, stumped. How do I test if it is the bios fried or the processor fried. I bought the processor used several months ago so I think this is the likely suspect. How do I tell? Any suggestions would be greatly appreciated. Thanks | |
