Citing unidentified people familiar with the situation, Bloomberg News said Dell has discussed a potential sale with at least two firms that specialize in buying companies whose stocks have fallen out of favor. The report didn't name the interested firms.
Dell Inc., based in Round Rock, Texas, declined to comment.
Any effort to take the company private would probably require the backing of Dell CEO and founder Michael Dell. He is the company's largest shareholder with a 15.7 percent stake.
A buyout also would be expensive, despite a 30 percent drop in Dell's share price during the past year. Before buyout speculation drove up the stock price Monday afternoon, Dell's market value stood at about $19 billion.
Dell stock's surged $1.41, or 13 percent, to close at $12.28. Earlier in the session, it touched its highest level since May, at $12.83. At one point, the stampede to snap up shares triggered a temporary halt in their trading on the Nasdaq market.
The possibility of a buyout had already been floated by some industry analysts who believe Dell might be better off trying to engineer a turnaround without having to deal with pressures from Wall Street to reverse a recent slide in revenue that has dragged down its stock.
Like most other PC makers, Dell has been hurt as more consumers embrace smartphones and tablet computers for Web surfing. The shift has curtailed demand for laptop and desktop computers, causing PC sales to fall last year for the first time since 2001.
Dell has been trying to adapt by reducing its dependence on PC's. The company has been expanding into business software and technology consulting services, two areas of technology that are more profitable than making PCs.
Hewlett-Packard Co., the only PC maker in the U.S. that's larger than Dell, is attempting a similar transformation.
Some analysts have argued that HP should be broken up so its PC and computer printer businesses operate separately.
HP rose 79 cents, or 4.9 percent, to close at $16.95 Monday.
