Litigation and Contingencies	6 Months Ended

Loss Contingency [Abstract]
Litigation and Contingencies	Litigation and Contingencies Hewlett Packard Enterprise is involved in various lawsuits, claims, investigations and proceedings including those consisting of IP, commercial, securities, employment, employee benefits and environmental matters, which arise in the ordinary course of business. In addition, as part of the Separation and Distribution Agreements between Hewlett Packard Enterprise and HP Inc. (formerly known as "Hewlett-Packard Company") and Hewlett Packard Enterprise and DXC (formerly known as "Everett SpinCo, Inc."), the parties to each agreement agreed to cooperate with each other in managing certain existing litigation related to both parties' businesses. The Separation and Distribution Agreements included provisions that allocate liability and financial responsibility for pending litigation involving the parties, as well as provide for cross-indemnification of the parties against liabilities to one party arising out of liabilities allocated to the other party. The Separation and Distribution Agreements also included provisions that assign to the parties responsibility for managing pending and future litigation related to the general corporate matters of HP Inc. (in the case of the separation of Hewlett Packard Enterprise from HP Inc.) or of Hewlett Packard Enterprise (in the case of the separation of Everett SpinCo Inc. from Hewlett Packard Enterprise), in each case arising prior to the applicable separation. Hewlett Packard Enterprise records a liability when it believes that it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated. Significant judgment is required to determine both the probability of having incurred a liability and the estimated amount of the liability. Hewlett Packard Enterprise reviews these matters at least quarterly and adjusts these liabilities to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other updated information and events pertaining to a particular matter. Litigation is inherently unpredictable. However, Hewlett Packard Enterprise believes it has valid defenses with respect to legal matters pending against the Company. Nevertheless, cash flows or results of operations could be materially affected in any particular period by the resolution of one or more of these contingencies. Hewlett Packard Enterprise believes it has recorded adequate provisions for any such matters and, as of April 30, 2017, it was not reasonably possible that a material loss had been incurred in connection with such matters in excess of the amounts recognized in its financial statements. Litigation, Proceedings and Investigations India Directorate of Revenue Intelligence Proceedings. On April 30 and May 10, 2010, the India Directorate of Revenue Intelligence (the "DRI") issued show cause notices to Hewlett-Packard India Sales Private Ltd ("HP India"), a subsidiary of HP Inc., seven HP India employees and one former HP India employee alleging that HP India underpaid customs duties while importing products and spare parts into India and seeking to recover an aggregate of approximately $370 million, plus penalties. Prior to the issuance of the show cause notices, HP India deposited approximately $16 million with the DRI and agreed to post a provisional bond in exchange for the DRI's agreement to not seize HP India products and spare parts and to not interrupt the transaction of business by HP India. On April 11, 2012, the Bangalore Commissioner of Customs issued an order on the products-related show cause notice affirming certain duties and penalties against HP India and the named individuals of approximately $386 million, of which HP India had already deposited $9 million. On December 11, 2012, HP India voluntarily deposited an additional $10 million in connection with the products-related show cause notice. On April 20, 2012, the Commissioner issued an order on the parts-related show cause notice affirming certain duties and penalties against HP India and certain of the named individuals of approximately $17 million, of which HP India had already deposited $7 million. After the order, HP India deposited an additional $3 million in connection with the parts-related show cause notice so as to avoid certain penalties. HP India filed appeals of the Commissioner's orders before the Customs Tribunal along with applications for waiver of the pre-deposit of remaining demand amounts as a condition for hearing the appeals. The Customs Department has also filed cross-appeals before the Customs Tribunal. On January 24, 2013, the Customs Tribunal ordered HP India to deposit an additional $24 million against the products order, which HP India deposited in March 2013. The Customs Tribunal did not order any additional deposit to be made under the parts order. In December 2013, HP India filed applications before the Customs Tribunal seeking early hearing of the appeals as well as an extension of the stay of deposit as to HP India and the individuals already granted until final disposition of the appeals. On February 7, 2014, the application for extension of the stay of deposit was granted by the Customs Tribunal until disposal of the appeals. On October 27, 2014, the Customs Tribunal commenced hearings on the cross-appeals of the Commissioner's orders. The Customs Tribunal rejected HP India's request to remand the matter to the Commissioner on procedural grounds. The hearings were scheduled to reconvene on April 6, 2015, and again on November 3, 2015 and April 11, 2016, but were canceled at the request of the Customs Tribunal. No new hearing date has been set. Department of Justice, Securities and Exchange Commission Proceedings. In April 2014, HP Inc. and HP Inc. subsidiaries in Russia, Poland, and Mexico collectively entered into agreements with the U.S. Department of Justice ("DOJ") and the Securities and Exchange Commission ("SEC") to resolve claims of Foreign Corrupt Practices Act ("FCPA") violations. Pursuant to the terms of the resolutions with the DOJ and SEC, HP Inc. was required to undertake certain compliance, reporting and cooperation obligations for a three-year period. In October of 2015, Hewlett Packard Enterprise contractually undertook the same compliance, reporting and cooperation obligations that were held by HP Inc. under the DOJ resolutions for the balance of the three-year period. Hewlett Packard Enterprise has reached a similar agreement with the Staff of the SEC, which is set forth in an amended SEC administrative order dated July 15, 2016. Hewlett Packard Enterprise’s obligations to the SEC expired in April 2017. Hewlett Packard Enterprise’s obligations to the DOJ run for three years following a court proceeding held in connection with the resolution, and thus continue until September 2017. ECT Proceedings. In January 2011, the postal service of Brazil, Empresa Brasileira de Correios e Telégrafos ("ECT"), notified a former subsidiary of HP Inc. in Brazil ("HP Brazil") that it had initiated administrative proceedings to consider whether to suspend HP Brazil's right to bid and contract with ECT related to alleged improprieties in the bidding and contracting processes whereby employees of HP Brazil and employees of several other companies allegedly coordinated their bids and fixed results for three ECT contracts in 2007 and 2008. In late July 2011, ECT notified HP Brazil it had decided to apply the penalties against HP Brazil and suspend HP Brazil's right to bid and contract with ECT for five years, based upon the evidence before it. In August 2011, HP Brazil appealed ECT's decision. In April 2013, ECT rejected HP Brazil's appeal, and the administrative proceedings were closed with the penalties against HP Brazil remaining in place. In parallel, in September 2011, HP Brazil filed a civil action against ECT seeking to have ECT's decision revoked. HP Brazil also requested an injunction suspending the application of the penalties until a final ruling on the merits of the case. The court of first instance has not issued a decision on the merits of the case, but it has denied HP Brazil's request for injunctive relief. HP Brazil appealed the denial of its request for injunctive relief to the intermediate appellate court, which issued a preliminary ruling denying the request for injunctive relief but reducing the length of the sanctions from five to two years. HP Brazil appealed that decision and, in December 2011, obtained a ruling staying enforcement of ECT's sanctions until a final ruling on the merits of the case. HP Brazil expects the decision to be issued in 2017 and any subsequent appeal on the merits to last several years. Forsyth, et al. v. HP Inc. and Hewlett Packard Enterprise. This purported class and collective action was filed on August 18, 2016 and an amended complaint was filed on December 19, 2016 in the United States District Court for the Northern District of California, against HP Inc. and Hewlett Packard Enterprise alleging defendants violated the Federal Age Discrimination in Employment Act ("ADEA"), the California Fair Employment and Housing Act, California public policy and the California Business and Professions Code by terminating older workers and replacing them with younger workers. Plaintiffs seek to certify a nationwide collective action under the ADEA comprised of all individuals aged 40 and older who had their employment terminated by an HP entity pursuant to a work force reduction ("WFR") plan on or after December 9, 2014 for individuals terminated in deferral states and on or after April 8, 2015 in non-deferral states. Plaintiffs also seek to certify a Rule 23 class under California law comprised of all persons 40 years or older employed by defendants in the state of California and terminated pursuant to a WFR plan on or after August 18, 2012. Wall v. Hewlett-Packard Enterprise Company and HP Inc. This certified California class action and Private Attorney General Act action was filed against Hewlett-Packard Company on January 17, 2012 and the fifth amended (and operative) complaint was filed against HP Inc. and Hewlett Packard Enterprise on June 28, 2016. The complaint alleges that the defendants paid earned incentive compensation late and failed to timely pay final wages in violation of the California Labor Code. On August 9, 2016, the court ordered the class certified without prejudice to a future motion to amend or modify the class certification order or to decertify. Trial is set to begin on June 19, 2017. Hewlett-Packard Company v. Oracle (Itanium). On June 15, 2011, HP Inc. filed suit against Oracle in Santa Clara Superior Court in connection with Oracle's March 2011 announcement that it was discontinuing software support for HP Inc.’s Itanium-based line of mission critical servers. HP Inc. asserted, among other things, that Oracle’s actions breached the contract that was signed by the parties as part of the settlement of the litigation relating to Oracle’s hiring of Mark Hurd. The matter eventually progressed to trial, which was bifurcated into two phases. HP Inc. prevailed in the first phase of the trial, in which the court ruled that the contract at issue required Oracle to continue to offer its software products on HP Inc.'s Itanium-based servers for as long as HP Inc. decided to sell such servers. Phase 2 of the trial was then postponed by Oracle’s appeal of the trial court’s denial of Oracle’s “anti-SLAPP” motion, in which Oracle argued that HP Inc.’s damages claim infringed on Oracle’s First Amendment rights. On August 27, 2015, the Court of Appeal rejected Oracle’s appeal. The matter was remanded to the trial court for Phase 2 of the trial, which began on May 23, 2016, and was submitted to the jury on June 29, 2016. On June 30, 2016, the jury returned a verdict in favor of HP Inc., awarding HP Inc. $3 billion in damages: $1.7 billion for past lost profits and $1.3 billion for future lost profits. On December 19, 2016, the trial court denied Oracle's request for a new trial. On January 17, 2017 Oracle filed a notice of appeal. On February 2, 2017, HP Inc. filed a cross-appeal. The Company expects that any appeal could take several years to be resolved and could materially affect the amount ultimately recovered by the Company. The amounts ultimately awarded, if any, would be recorded in the period received. Pursuant to the terms of the Separation and Distribution Agreement, HP Inc. and Hewlett Packard Enterprise will share equally in any recovery from Oracle once Hewlett Packard Enterprise has been reimbursed for all costs incurred in the prosecution of the action prior to the HP Inc./Hewlett Packard Enterprise separation on November 1, 2015. Network-1 Technologies, Inc. v. Alcatel-Lucent USA Inc., et al. This patent infringement action was filed in September 2011 in the United States District Court for the Eastern District of Texas and alleges that various Hewlett Packard Enterprise switches and access points infringe Network-1’s patent relating to the 802.3af and 802.3at “Power over Ethernet” standards. The Network-1 patent at issue expires in 2020. On June 1, 2017, the Court held a hearing on HPE’s motion for summary judgment. No ruling has yet been issued. Trial is currently scheduled to begin on November 6, 2017. Environmental The Company's operations and products are or may in the future become subject to various federal, state, local and foreign laws and regulations concerning environmental protection, including laws addressing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, the clean-up of contaminated sites, the substances and materials used in the Company's products, the energy consumption of products, services and operations and the operational or financial responsibility for recycling, treatment and disposal of those products. This includes legislation that makes producers of electrical goods, including servers and networking equipment, financially responsible for specified collection, recycling, treatment and disposal of past and future covered products (sometimes referred to as "product take-back legislation"). The Company could incur substantial costs, its products could be restricted from entering certain jurisdictions, and it could face other sanctions, if it were to violate or become liable under environmental laws or if its products become non-compliant with environmental laws. The Company's potential exposure includes impacts on revenue, fines and civil or criminal sanctions, third-party property damage or personal injury claims and clean-up costs. The amount and timing of costs to comply with environmental laws are difficult to predict. In particular, the Company may become a party to, or otherwise involved in, proceedings brought by U.S. or state environmental agencies under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), known as "Superfund," or other federal, state or foreign laws and regulations addressing the clean-up of contaminated sites, and may become a party to, or otherwise involved in, proceedings brought by private parties for contribution towards clean-up costs. The Company is also contractually obligated to make financial contributions to address actions related to certain environmental liabilities, both ongoing and arising in the future, pursuant to its separation and distribution agreement with HP Inc.

Environmental

The Company's operations and products are or may in the future become subject to various federal, state, local and foreign laws and regulations concerning environmental protection, including laws addressing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, the clean-up of contaminated sites, the substances and materials used in the Company's products, the energy consumption of products, services and operations and the operational or financial responsibility for recycling, treatment and disposal of those products. This includes legislation that makes producers of electrical goods, including servers and networking equipment, financially responsible for specified collection, recycling, treatment and disposal of past and future covered products (sometimes referred to as "product take-back legislation"). The Company could incur substantial costs, its products could be restricted from entering certain jurisdictions, and it could face other sanctions, if it were to violate or become liable under environmental laws or if its products become non-compliant with environmental laws. The Company's potential exposure includes impacts on revenue, fines and civil or criminal sanctions, third-party property damage or personal injury claims and clean-up costs. The amount and timing of costs to comply with environmental laws are difficult to predict.

In particular, the Company may become a party to, or otherwise involved in, proceedings brought by U.S. or state environmental agencies under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), known as "Superfund," or other federal, state or foreign laws and regulations addressing the clean-up of contaminated sites, and may become a party to, or otherwise involved in, proceedings brought by private parties for contribution towards clean-up costs. The Company is also contractually obligated to make financial contributions to address actions related to certain environmental liabilities, both ongoing and arising in the future, pursuant to its separation and distribution agreement with HP Inc.
