Geragos, who testified that he investigated the accuser's family and became gravely concerned about them, was cross-examined on whether he ever asked Jackson if the boy slept in his bed.
"Yes, he said nothing happened," Geragos testified. "He said he didn't do anything untoward or sexual and if anyone spent the night in his room it was unconditional love."
As the Jackson trial recessed for the weekend, Geragos is scheduled to return to the stand next Friday.
Geragos also gave a ringing defense of his former client as he described his first visit to Jackson's Neverland ranch.
"When I was there, what I saw was a gentleman who was almost childlike in his love for kids. I didn't see anyone doing anything nefarious or criminal. I saw someone who was ripe as a target," he said.
Geragos said he was hired around the time of the February 2003 airing of a documentary in which Jackson appeared with the boy now accusing him of molestation. In the documentary, Jackson said that he let children sleep in his bed but that it was non-sexual.
"I'm sure jurors aren't surprised to hear Jackson's former attorney say nice things about him. And I am sure they are factoring in the relationship between the defendant and Geragos," said CBS News Legal Analyst Andrew Cohen. "But the attorney did reinforce a main defense theme -- that of Jackson as victim -- and gave specific examples in doing so. And that is a big deal."
Under questioning by Jackson attorney Thomas Mesereau Jr., Geragos said he was concerned about allegations spawned by the documentary and was particularly concerned that the boy or his family might take advantage of them.
He said he did database searches to see if the family had a "litigious history" and was disturbed to find they had previously sued J.C. Penney over allegations they were beaten by security guards. The family received a $150,000 settlement.
"I was gravely concerned," Geragos said.
Geragos said he hired a private investigator to look into the family, and the results led him to believe the family was bad news.
"Michael should have nothing to do with them," he said. "It was a pending disaster."
Mesereau asked Geragos if he was aware of any crime committed against the family. Geragos said no.
"I was trying to prevent a crime against my client," he said. "I thought that they were going to shake him down."
Jackson replaced Geragos as his attorney in April 2004.
Geragos came to court under threat of arrest. Judge Rodney S. Melville issued the warning Thursday when a Geragos colleague sought to reschedule his testimony because of other courtroom obligations. But the judge ordered him to be there at 8:30 a.m.
Geragos arrived well in advance but then waited around for hours while attorneys questioned another witness. The judge became exasperated.
"I have this picture of a lawyer upstairs walking back and forth pulling his hair out of his head wondering why I called him here today under threat of a warrant while Mr. Mesereau goes on and on," the judge said. "What's wrong with that picture?"
Mesereau replied, "It's pretty accurate, I think, your honor."
CBS News Legal Analyst Wendy Murphy said on CBS News' The Early Show that she's not sure Geragos will help Jackson.
"I'm not sure it's good for Michael Jackson that his lawyer appears to have been so much involved in the conspiracy that he literally has to take the stand and take the heat for it," she told Early Show co-anchor Julie Chen.
