Now that that's out of the way, the reason for this post. Until yesterday everything was working fine until I decided it's time attempt to unlock the CPU. I had been reading everthing I could find on the subject and was fairly confident (maybe too confident) that I could do the job.

I started by removing cpu and cleaning area around L1

Damn laptop keyboard is too small. I'll continue now.
So as I was saying, after cleaning the area round the L1 bridges with alcohol, I masked off the areas round the L1 bridges only leaving the pits exposed and filled them with white crayon. I removed the excess and under magnification, I had 5 white lines of wax filling the pits in the L1 bridge area. I masked off the First bridge and painted the contacts together using the rear defogger repair kit paint. I repeated the process until all five bridges were connected. Excited, I replaced the CPU in the motherboard and powered it up. All I got was a steady BEEEEP.

Not good, I then took the CPU out and inspected the contacts, all clean and no others touching. After several inspections and touchup attempts, I decided to back out of the unlock.

I did this by scraping off the Conductive paint with hobby knife under the magifiying glass and then cleaned area with alcohol.
The problem is, still won't boot, only get the steady BEEP.

Anyone else have a similar experience?

Thanks

What did you use to fill the gaps and connect the bridges? A little acetone or mineral spirits might clean it off if it's not something too permanent.

The kit from highspeedPC is very easy to work with and you can always start over if you screw up. You might have the connections touching each other. Try using a sewing needle instead of a straight pen to paint the lines. It's much sharper and easier to keep neat lines. And make sure you've got a powerful magnifying glass or loop.

Thanks AntiM;

I used a white crayon to fill the pits and am wondering if some of the paint leaked past the wax of the crayon. I think I remember this being a very bad thing.

Thanks for the sewing needle suggestion, the straigt pin seem pretty big.
