Hello,
I just bought a used Mac Book Pro (Late 2007) with a Dual Core 2.4 Ghz cpu and 2 GB of Ram.
I went to my parts supplier yesterday to upgrade the RAM to 4 GB. He pulled out a matched pair of 2Gb that precisely match the chip in the computer.
I installed both, but the Mac Book would not boot. So, I removed the new ones and put the old ONE back in....Mac Book boots no problem!
So, I thought maybe there is something wrong with one of the slots. So, I took the chip out of the one slot and put it in the other.....Mac Book boots no problem.
So, I put the new RAM back in BOTH slots.....Mac Book would NOT boot.
So....the only conclusion I could come to is that the Mac Book will not boot with both slots filled with the Maximum 4 Gb of RAM.
Has anyone seen this problem before and if so, how do I fix it?
TIA
Bill
Hope this is the right forum
