I did, see my comments for seanbirss below.
Apply more heat. It didn't work for me the first time. I opened it up again and this time, I warmed the entire board first until warm to the touch. Put a book on the edge of one side of the board that doesn't have the two prongs sticking out to level it up so when you heat/melt the soIder, the chips don't move around. I applied low heat on the back of the CPUs and the rams for 90 seconds each. I waited for the board to cool down before turning it over (make sure not to move the board during the cool down process as you might disturb the chips). Now apply more heat to the front of the motherboard directly over the CPUs and th rams for about 60 seconds on each. Wait for it to cool down completely before apply thermal paste and reassemble the unit. Good luck.
Hi, is there a guide to reassemble the unit after repair. After 50 steps of taking the unit apart, I don't think i will remember how to put them back properly without a guide. Going backwards with the steps would be very confusing. Thanks fo any reply.
