# HP ProBook
**HP ProBook** is a line of business-oriented notebook computers made by [HP Inc.](https://www.edgepedia.org/hp-inc), positioned below the premium EliteBook line and aimed at small to medium-sized businesses and budget-conscious buyers. The line was introduced in April 2009 as the ProBook s-series and, since 2025, has been sold as the ProBook 4 series in 14-inch and 16-inch sizes with Intel and AMD processor options.[1](https://www.engadget.com/2009-04-28-hp-unveils-probook-s-series-laptops-for-the-businessperson-who-n.html) • [2](https://www.hp.com/us-en/tech-takes/laptops/comparison/elitebook-vs-probook.html) • [3](https://www.techradar.com/pro/hp-follows-dell-by-simplifying-almost-its-entire-pc-range-across-laptops-and-desktops-just-in-time-for-ai)

## Positioning within HP's lineup
HP describes the ProBook as its value-oriented business line. The EliteBook series is designed for executives and professionals who need premium performance, security, and design, while the ProBook series is geared toward small to medium-sized businesses and offers a balance of performance, durability, and value. HP's third business notebook family, the ZBook, serves as high-performance mobile workstations for creative and technical professionals.[2](https://www.hp.com/us-en/tech-takes/laptops/comparison/elitebook-vs-probook.html) • [8](https://www.hp.com/us-en/tech-takes/laptops/comparison/comparing-business-laptops-elitebook-probook-zbook.html)
In practice the two lines overlap in configuration.
## History
**2009 launch.** HP announced the ProBook s-series on April 28, 2009, as affordable business-centric laptops. The line comprised the 14-inch 4410s (Intel) and 4415s (AMD) with an optional Blu-ray drive and HDMI port, the 15.6-inch 4510s and 4515s with an optional mobile broadband module and integrated numeric keypad, and the 17.3-inch 4710s. Prices started around $529, and HP offered Novell SuSE Enterprise Desktop 11 preinstalled, which the company described as a first for it.[1](https://www.engadget.com/2009-04-28-hp-unveils-probook-s-series-laptops-for-the-businessperson-who-n.html) PCWorld characterized the line as merging business functionality with consumer features such as HD graphics and Blu-ray drives, with a choice of Intel or AMD processors and 14-, 15.6-, or 17.3-inch 16:9 widescreens.[9](https://www.pcworld.com/article/528768/hp_new_laptops.html) In Japan, HP ProBook 4510s/CT configurations started at ¥64,890 and the 4515s/CT at ¥59,850.[10](https://www.itmedia.co.jp/pcuser/articles/0905/27/news048.html)
**G-series numbering.** Through the 2024/2025 model years the notebooks carried names such as ProBook 440 G11 and 445 G11 (14-inch) and 460 G11 and 465 G11 (16-inch).[11](https://www.techoutlet.eu/en/laptops/hp/probook.html) The 2024 G11 generation was marketed as AI-capable machines built for hybrid workers, with upgradeable storage and memory and 50% post-industrial recycled stamped aluminum in the chassis.[12](https://www.hp.com/us-en/newsroom/press-releases/2024/hp-unveils-largest-portfolio-ai-pc.html)
**Renaming in 2025.** At the HP Amplify 2025 event, HP simplified its commercial PC names: the 800 and 600 series became EliteBook 8 and EliteBook 6, and the 400 Series became ProBook 4 in 14- and 16-inch sizes.[3](https://www.techradar.com/pro/hp-follows-dell-by-simplifying-almost-its-entire-pc-range-across-laptops-and-desktops-just-in-time-for-ai) The new scheme adds a platform letter: ProBook 4 G1i and G2i are the Intel versions and ProBook 4 G1a and G2a the AMD variants.[11](https://www.techoutlet.eu/en/laptops/hp/probook.html) The G1 generation comprises three sub-lines: the G1a with [AMD Ryzen](https://www.edgepedia.org/amd-ryzen) 5 and Ryzen 7 APUs (a 16 TOPS NPU indicates Ryzen 200 Hawk Point Refresh parts), the G1iR with Intel Meteor Lake Core Ultra 3, Ultra 5, Ultra 7, and 13th-gen Core 5-1334U options, and the G1i with Core Ultra 5 and Ultra 7 U- and H-series processors plus an optional Nvidia GeForce RTX 3050 Laptop GPU with 4 GB of dedicated VRAM.[4](https://www.notebookcheck.net/HP-s-new-ProBook-4-series-offers-entry-level-AI-from-Intel-Meteor-Lake-and-AMD-Ryzen-200-for-remote-work-and-collaboration.981372.0.html)
**G2 generation.** At HP Imagine on March 24, 2026, HP announced the ProBook 4 G2 Series, including the ProBook 4 Flip G2i convertible, described as transforming workflows for growing SMBs with AI-enabled performance and durability; the devices were expected on HP.com starting in April 2026.[13](https://www.hp.com/us-en/newsroom/press-releases/2026/hp-enables-best-work-in-more-places.html)
## Current hardware
The ProBook 4 G1i 16 inch Notebook AI PC ships with Windows 11 Pro, an Intel Core Ultra 7 255U (up to 5.2 GHz, 12 cores, 14 threads), 16 GB of DDR5-5600 memory in two SODIMM slots, a 512 GB PCIe NVMe SSD, integrated Intel graphics, and a 65 W USB Type-C adapter. Wireless options include Intel Wi-Fi 7 BE201 with [Bluetooth 5](https://www.edgepedia.org/bluetooth-5).4, and the keyboard is a spill-resistant, full-size unit with numeric keypad.[5](https://www.hp.com/ie-en/products/laptops/product-details/product-specifications/2103766525) The 14-inch G1i shares the same port set and processor family, with configurations down to 8 GB of memory and a 1080p FHD camera, and an optional fingerprint reader.[14](https://www.hp.com/ph-en/products/laptops/product-details/product-specifications/2103161433) Select models use a 5 MP camera with IR for Windows Hello biometrics, and all models can be configured with optional 4G LTE and a 48 Whr or 56 Whr battery.[4](https://www.notebookcheck.net/HP-s-new-ProBook-4-series-offers-entry-level-AI-from-Intel-Meteor-Lake-and-AMD-Ryzen-200-for-remote-work-and-collaboration.981372.0.html)
The AMD-based ProBook 4 G1a reviewed by TechRadar used an AMD Ryzen 7 250 ([Zen 4](https://www.edgepedia.org/zen-4), up to 5.1 GHz, 8 cores, 16 threads, 16 TOPS NPU) with Radeon 780M integrated graphics, 32 GB of DDR5 upgradeable to 64 GB, a 1 TB PCIe NVMe SSD, a 14-inch WUXGA (1920 × 1200) touchscreen, and a 56 Wh Li-ion polymer battery in a 1.4 kg chassis; pricing started at $973/£744/€860.[15](https://www.techradar.com/pro/hp-probook-4-g1a-business-laptop-review) The reviewer noted the absence of [Thunderbolt](https://www.edgepedia.org/thunderbolt) and USB 3.2 Gen 2 Type-A ports as deliberate cost choices, and praised the upgradeable memory and single M.2 slot.[15](https://www.techradar.com/pro/hp-probook-4-g1a-business-laptop-review)
**Serviceability** is a distinguishing trait of the line. HP publishes maintenance and service guides and part-replacement videos for the ProBook 4 G1i covering the battery, M.2 SSD, memory modules, wireless module, fan, and system board, and the G1i 16 lists two SODIMM slots for memory upgrades.[16](https://www.youtube.com/watch?v=aYs0GJ-m75Y) • [5](https://www.hp.com/ie-en/products/laptops/product-details/product-specifications/2103766525) This contrasts with thinner EliteBook models such as the EliteBook Ultra G1i, whose memory is soldered to the motherboard.[17](https://www.techradar.com/pro/hp-elitebook-ultra-g1i-business-laptop-review)
## Security and management
ProBooks carry HP's business security stack. HP Wolf Security for Business requires Windows 10 Pro or higher and is available on HP Pro, Elite, RPOS, and [Workstation](https://www.edgepedia.org/workstation) products.[6](https://www.hp.com/us-en/security/computers-and-printers-hardware.html) The ProBook 445 G11 datasheet lists a TPM 2.0 embedded security chip certified at Common Criteria EAL4+, Enhanced Sign-in Security, and Secured-Core PC enablement, with a 3-cell 56 Whr standard or Long Life battery.[7](https://h20195.www2.hp.com/v2/GetDocument.aspx?docname=4AA8-3668ENW) Compared with EliteBooks, ProBooks offer a more basic security set: HP's own comparison lists HP BIOSphere, HP Client Security Manager, and an optional fingerprint reader for ProBooks, while EliteBooks add HP Sure Start self-healing BIOS, HP Sure View integrated privacy screens on select models, and HP Sure Sense AI malware protection.[2](https://www.hp.com/us-en/tech-takes/laptops/comparison/elitebook-vs-probook.html)
## Sustainability
The ProBook 4 G1i 16 lists at least 50% recycled metal, at least 25% post-consumer recycled plastic, and at least 50% ocean-bound plastic in specified components, with paper-based packaging from recycled or certified sources.[5](https://www.hp.com/ie-en/products/laptops/product-details/product-specifications/2103766525) The 14-inch model specifies at least 50% ocean-bound plastic in the fan enclosure.[14](https://www.hp.com/ph-en/products/laptops/product-details/product-specifications/2103161433)
