    Desktops & All-in-Ones

    Notebooks

    Some products utilize the keyboard shortcut 'Fn + Esc'; the product information will appear after a short delay. If that doesn't work, this information can also be found on your bar code stickers, which may be located behind the battery.

    Printers (Both HP and Samsung)

    Look for the bar code stickers on your printer.The Serial number on a Samsung printer can be used wherever an HP serial number is requested. Samsung printers refer to a 'product number' as a 'model code' designated with 'M/C', and typically start with 'SL-_'.

    Tablets

    Your product information is typically located on the back or bottom edge of your product.

    Small enough to be everything you need

    If you're looking for a small form factor computer, you want a PC that takes up less space without sacrificing performance. We think that's a reasonable request, and it’s why we created the HP ProDesk 400.


    With power for your most important tasks, the security to keep your work safe, and the ability to stand the test of time, you'd be hard-pressed to find a more reliable asset to add to your team.


    Hardware built to grow with your business

    We know your business can't afford to invest in a computer that's left in the dust by every new feature and capability coming around the corner. That's why we built the ProDesk 400 G4 to be here today, and here tomorrow.


    With two half-height slots for PCI cards, two bays, and optional legacy ports, you'll have all you need to expand your capabilities into the future as it comes, or connect devices of the past that still serve their purpose.


    Not only does it have what it takes to keep up with changes in the standards of computers, or those of your business, it's built to survive the sometimes harsh elements and heavy use that comes with being an indispensable device in your office.


    After going through 120,000 hours worth of testing—the equivalent of 5,000 days—you can be sure you’re getting a small form desktop computer that’s designed to be in it for the long haul, just like your business. And with an optional dust filter, your investment can continue taking care of itself, even in the most demanding office environments.


    Small design, small footprint, smaller energy costs

    When you get a small form factor computer, you get something that can fit in your office the way a great new hire can fit in with your team. With easier portability when you need it compared to your standard, bulkier desktops, you won’t be hassled to move around if you need to call another location home.


    Because of its size, you’ve found the missing piece of the puzzle when it comes to creating a workspace that fits your needs. With smaller dimensions, it can accomodate your expansion if you’re looking for a PC that can make it easier to squeeze in another desk.


    It doesn’t just save space—it saves you energy, too. With a 180 watt internal power supply that provides up to 85% efficiency, you’ll get the required power without anything extra that could potentially drive up your power bill.


    Performance built to push you forward

    Despite its manageable size, you get a heavyweight punch. The 7th Generation Intel® Core™ Processor provides the push you need, whether that’s on a last-minute project, or the daily tasks that require a little extra power to work through.


    When you combine the optional Intel® Optane™ memory with the installed 500GB HDD storage, you’ll get the speed associated with SSD devices, plus the extra space you need for all of your important files and data.


    If you want a small form factor Windows PC, we’ve got you covered. With Windows 10 Pro 64, you get a sleek design with tools to assist you like Cortana, and tools to secure you and your business like Windows Information Protection, Device Encryption, and Bitlocker.


    Security tools that look out for your business even when you’re getting shut-eye

    In addition to receiving protection with Windows 10, you’ll also get the necessary security features from HP as soona s you power up your computer.


    If you’re looking to avoid downtime and keep your business producing, the firmware-level automation provided by HP BIOSphere Gen3 can help you do it. Automatic updates and security checks give you one less thing to worry about when it comes to staying secure and in operation.


    The HP Client Security Suite Gen3 can provide even more protection, giving you all of the tools you need to keep what’s yours right where it needs to be. Multi-factor Authenticate allows you to use fingerprints or facial recognition to keep your PC from being accessed by anyone that’s not on the same team.


    HP Device Access Manager allows you to prevent unauthorized use of your computer, while SpareKey can recover lost system passwords to save you from the avoidable tasks that distract you from your actual work. And with HP Password Manager, you can securely store your passwords to keep a worst case scenario from ever happening.


    Peace of mind in the palm of your hand

    You may not always be in the office, but you’ll always want to ensure your PC is safe, which is why we offer HP WorkWise. With WorkWise, you get a smartphone app that can provide you with real-time updates in the palm of your hand.


    If you want to know if someone is attempting to tamper with your device, or if everything that needs to be connected is connected, you’ll know it. You’ll also be made aware of a change right when it happens.


    Checking the status of your device isn’t the only feature you’ll find helpful. With PC lock, you can automatically lock your screen whenever you step away, and unlock it whenever you come back.


    And to make computer maintenance even easier, you can install printer drivers with a quick scan of your HP Printer’s QR code using the WorkWise app.


    The next best addition to your team might be a PC

    You hire new employees to be there for your business today, and in the uncertain tomorrow. We built the ProDesk 400 to do the same.


    When you choose a small form factor desktop computer from HP, you get the reliability, security, capabilities, and size to be the perfect fit for your business, now, and far into the future.
