Simple fix! Is there no ECC memory in laptops? Oops ... found the answer to that one at ...
<http://www.quora.com/Are-there-any-laptops-with-ECC-memory> <snip> " Trevor Inkpen, CanadaRAM.com - memory and hard drive... In general, laptops do not use ECC memory. There may be military-spec models available, but you will not find ECC memory on any retail laptop model. For ECC to be implemented, the motherboard memory controller must support ECC. Laptops are designed and sold for the consumer market, for light weight, portability and long battery life. Unlike desktop machines, laptop motherboards are not standardized designs but are custom designed for each model line, so there is no ability to swap in alternate motherboards with ECC capability. Very few laptops are designed and sold for industrial or scientific use, although there are some ruggedized laptops which are sold for military and law enforcement applications, and there are some (very rare) ECC SODIMMs produced by Samsung.
