EXCLUSIVE: What WASN'T in Hunter Biden's book: How he got unauthorized Secret Service protection, begged Joe to run for WH to salvage his own reputation and made porn films with prostitutes. Forensic experts prove laptop IS President's son's

 Hunter Biden's 'tell-all' autobiography promised the unvarnished story of his struggles with drugs, family turmoil and his controversial love life.

But there were many shocking details of his debauched life that the president's son chose not to share with readers, including details of his fragile relationship with his father.

Now DailyMail.com can reveal the secrets Hunter chose not to divulge, exposed in the contents of his abandoned laptop and verified by top forensics experts.

The bombshell cache of 103,000 text messages, 154,000 emails, more than 2,000 photos and dozens of videos are packed with revelations conveniently missing from the memoir, including:

• How he begged his father to run for president in 2019 to salvage Hunter's own reputation
• How he repeatedly dodged police action against him, despite constantly dealing with drug pushers and prostitutes and having multiple run-ins with law enforcement
• Hunter was guarded by a Secret Service agent while on a 2018 drug and prostitute binge in Hollywood, despite not being entitled to protection at the time and amid denials from the federal agency
• Joe Biden was afraid his text conversations with Hunter were being hacked even as they discussed his White House bid
• How Hunter's laptop is brimming with evidence of apparent criminal activity by Hunter and his associates including drug trafficking and prostitution

Hunter Biden released his 'tell-all' memoir Beautiful Things on Tuesday, but left out shocking details.

Hunter left his MacBook Pro laptop at a Wilmington, Delaware computer repair shop in April 2019 and never returned for it. The report said the data on the drive 'appear to be authentic', and that after an extensive search of its contents for any tell-tale signs of tampering, Maryman and Greenfield found 'no evidence' of fabrication – by Russians or anyone else

The president's son left his 2017 MacBook Pro laptop at a Wilmington, Delaware computer repair shop in April 2019 and never returned for it.

Emails leaked from the computer sparked a scandal before the 2020 presidential election in October, but were dismissed as Russian disinformation by the Bidens and other senior Democrats, social media giants Twitter and Facebook, and several major media organizations.

After obtaining a copy of the hard drive, DailyMail.com commissioned top cyber forensics experts Maryman & Associates to analyze its data and determine whether the laptop's contents were real.

The firm's founder, Brad Maryman, is a 29-year FBI veteran Supervisory Special Agent who served as an Information Security Officer and founded its first computer forensics lab.  

Maryman and his business partner Dr. Joseph Greenfield used the same forensic tools to pick apart the drive as federal and state law enforcement use in criminal investigations, and prepared a report for DailyMail.com.

The report said the data on the drive 'appear to be authentic', and that after an extensive search of its contents for any tell-tale signs of tampering, Maryman and Greenfield found 'no evidence' of fabrication – by Russians or anyone else.

'The data on the system before April 2019 appears to be related to Mr. Biden, with timestamps appearing to be between 2016 and 2019,' the Maryman and Associates report said.

'The operating system timestamps appear to be authentic, and no evidence was found to suggest that the timestamps or data were altered or manufactured. No indications were found that would indicate the data was manufactured.'

In a presidential debate in October, Joe Biden referred to the leaks of Hunter's emails as 'a bunch of garbage.'

But in an interview with CBS on Sunday to promote his new book, Beautiful Things, Hunter said the laptop 'could be' his.

'There could be a laptop out there that was stolen from me. It could be that I was hacked. It could be that it was the — that it was Russian intelligence. It could be that it was stolen from me or that there was a laptop stolen from me,' he said.

When Joe texted him a typically doting message 'Good morning my beautiful son. I miss you and love you. Dad' on February 24 that year, Hunter raged at his father for 'having made clear to the world that the only reason for not [running for president is your] family problems im glad to be the f***ing bullseye you painted on my back'

In March 2019, Joe Biden offered to pay his granddaughter Maisy's dentist bills when Hunter ran out of money

Among the 103,199 text messages on the hard drive dating from 2016 to March 2019 are fraught conversations between President Joe Biden and his son.

The texts reveal how Joe was sucked into his son's torrid love life, became a punching bag for Hunter's drug-fueled rants, and paid his grandchildren's bills when Hunter had drained his bank accounts from his spending on prostitutes and crack cocaine.

When the former Delaware senator was elected Vice President in 2008, it put an end to Hunter's lucrative career as a lobbyist to avoid the appearance of conflicts of interest.

Hunter then embarked on a series of controversial business ventures and fell into a cycle of crack and prostitute binges, scandal and rehab.

By 2019 his texts appeared to be seething with resentment.

When Joe texted him a typically doting message 'Good morning my beautiful son. I miss you and love you. Dad' on February 24 that year, Hunter raged at his father for 'having made clear to the world that the only reason for not [running for president is your] family problems im glad to be the f***ing bullseye you painted on my back.'

Hunter complained that his father's advice to not defend himself in the media over stories about his expensive divorce from his ex-wife Kathleen Biden or his affair with his brother's widow Hallie had backfired, and added sarcastically: 'Oh …good morning …from f***ing rehab.'

'Your team just made me the uncontrollable troubled tax cheat philanderer sex and drug addict that you tried so hard to fix but couldn't yt. They just totally wrote my life away,' he wrote.

'If you dont run ill never have a chance at redemption.'

Joe replied, promising his son he would run for President but adding that he was worried his texts were 'a target' for hacking.

'I'll run but I need you,' he wrote. 'H[allie] is wrong. Only focus is recovery. Nothing else... When you can and feel like it call. Positive my text etc a target. Love.'

He declared his candidacy two months later.

After another rant from Hunter in September 2018 Joe wrote: 'Be careful what you text. Likely I'm being hacked.'

The future president had good reason to worry, as his phone was filling up with incriminating and embarrassing texts as his son's relationship with Hallie disintegrated, according to Hunter's messages to him.

When Hunter's controversial affair with Beau's widow was publicly revealed in March 2017, Joe reluctantly released a statement giving the couple his blessing.

But a year later he was already being drawn into the couple's meltdown by his erratic, addict son.

In July 2018 Hunter sent a recording to his father of himself talking on the phone to Hallie.

Joe responded: 'Got your text. Can't say I'm surprised. Going to bed I'll call you tomorrow morning. Love you. Be strong. Love Dad.'
