I feel your pain, some brands like it opaque ... You're looking for something specific with very generic search terms. The only way to get something done is by searching on a search engine that includes generic word tags, such as ebay. Thus, searching for "lifebook e554 motherboard" on ebay generated a lot of results, but this one seems promising : http://www.ebay.ca/itm/NEW-Motherboard-Fujitsu-Siemens-LIFEBOOK-U554-U574-CP646283-XX-Intel-i7-4500U-/252698544516?hash=item3ad601c984:g:DPwAAOSwa~BYYmbJ We can then find out that the motherboard model number would be CP646283, and that it probably is also compatible with the Lifebook U574. That would be an easy way of verifying the information is correct. Hope this can help !
