How do I turn on a powerbook 667 logic board

Submitted by sjb on February 8, 2005 - 2:08am. Hardware Hacks

Hi,

I'm building a "Macenstein" from a 667 logic board. I have placed the RAM, hard drive, and dvd drive. I plugged the AC in, but there's no way to turn it on. How do I do that? Is there a switch hack?

Thanks,
Steven

Find the power button port

There should be a little two prong plug/port that the cable for the power button plugs into. Just short that (preferably by using a real power button) briefly and it should boot. This worked for my iBook.

That will make a great mac Smiling It will also make a great machine for overclocking as powerbook processors when properly cooled can normally do some huge overclocks.

How is overclocking done on the 667?

Submitted by sjb on February 8, 2005 - 5:36pm.

Hi,
Several thoughts...
1. how difficult is it? I haven't done any motherboard soldering before :-(
2. which jumpers/resistors does one move?
3. what's the speed gain
4. what type of cooling would you suggest? I was going to add an aluminum heat sink to the processor...do I need more?

Thanks
Steven

Don't do it!

If you haven't done overclocking before, a laptop board is not the place to start.

Yeah, I answered so fast cause I learned about the power plug as I was trying to overclock my iBook and I needed to check it before reassmbly.

Oh, and I failed to overclock the iBook and in fact killed the mobo.

I am sory to hear about your ibook. Thanks everyone for your input. I wil not overclock my logic board!
I'll post pictures - I'm planning to use 2 clear acrylic sheets and 4 acrylic rods (at the corners) and hook it up to an external VGA LCD.
