SAN FRANCISCO (MarketWatch) -- Hewlett-Packard Co. and its financial advisers have performed an internal analysis that suggests the company may be better off keeping its PC business rather than spinning off the unit, according to a report in the Wall Street Journal on Tuesday afternoon. H-P HPQ, +0.37% said in August that it was evaluating options for the business, which included a potential spin-off. Citing unnamed sources, the WSJ report said a new analysis indicated that the company could lose buying power with component suppliers and create problems in its supply chain if it gave up the PC business, which contributed about $40 billion in revenue in the company's most recent fiscal year.
