If Microsoft joins in a Dell buyout, CNBC and the Journal say the software maker would contribute $1 billion to $3 billion. That amount would make Microsoft Corp. a minority investor in a complex deal expected to cost $23 billion to $27 billion if it's completed.
The reports tying Microsoft to the Dell buyout talks cited people familiar with the negotiations who didn't want to be identified.
Microsoft declined to comment.
Word that Dell Inc. is interested in selling to a group led by buyout firm Silver Lake Partners first surfaced last week. Dell's stock price has climbed about 20 percent to around $13.16 since then.
