Everything your business needs from a computer in the HP ProBook 645

With the HP ProBook 645, you can supply your workforce with the tools to take on your biggest business challenges.

You also have the ability to customize, so you can better fit your needs and budget. And no matter which choice you make, we offer impressive performance capabilities and security.

Customizable to handle whatever the job calls for

With the ProBook 645, you’re not locked into one set of features, giving you the versatility your business requires. The optional 14" diagonal FHD touch screen allows you to get your work done with a swipe of a finger.

Paired with the Windows 10 Pro’s built-in touch keyboard, you can use the optional touch screen to quickly take notes, whether in a meeting or on the run.

And if you’re looking for legacy support, we offer the optional optical drive, native serial ports, a standard VGA port, and an RJ-45 connection. If you want the space an HDD drive provides, or the extra speed of an SSD drive, we offer those as well.

Impressive performance that keeps you up and running

You need a computer that will keep up with you as you stay ahead of the competition. With the ProBook 645’s strong DD3 memory, you won’t be waiting for programs to respond in the middle of a presentation, or in any other key moments when “let’s come back to this later” just won’t do.

Throw in a 7th generation AMD processor, and the brain of your PC will be running just as smooth as yours after that first cup of coffee.

Durable enough to bounce back from an inevitable “oops”

You designed your business to be built to last, and we’ve designed the HP ProBook 645 that way as well. Whatever beverage you choose to fuel your progress, the HP Premium spill-resistant keyboard is there to protect your investment from a cup that loses a battle with gravity.

HP’s DuraKeys and optional backlight can take the pounding you dish out, while keeping you from hitting the wrong key long after the lights have been turned off.

You never know when a slip or a drop may happen, but you can feel secure knowing this notebook PC was built to pass the United States military’s MLD-STD 810G testing, meaning it can withstand much of the punishment the world inevitably throws your way.

The security you need

News stories emerge every day reminding you that more than ever, business security is essential in our quickly evolving world. With the HP Security Suite, you’ll have the protection you need to be confident every time you put your work to the side.

Do you handle sensitive data internally and the data of clients?

If so, you’ll enjoy the hard drive encryption included, and the ability to restrict access to those that may not have you or your organization’s best interests at heart. And when it comes time to getting rid of your valuable data securely, the HP Security Suite allows you to permanently delete or discard it. PC business security is no laughing matter, and the HP ProBook 645 makes that happen.

Whether you need to safeguard your business at a hardware, software, or BIOS level, we’ve got you covered. With HP BIOSphere, you can control startup and login information with BIOS-level password protection.

An optional fingerprint reader offers a unique way to control access to your device, and when you throw in Windows 10 Pro’s built-in security features, you’ll have the peace of mind necessary to tackle any workload with all you've got.

The world is your conference room

Business calls for collaboration, whether you’re in the office or on the move. Skype for Business paired with our 720p webcam allows you to reach out to the rest of the world from wherever in the world you may be.

With the ability to meet with up to 250 people, the option to record meetings, and the Microsoft Office apps you need to get the job done, distance is eliminated with a click.

There are few things more important than clear communication when you’re talking to clients or coworkers. HP Noise Reduction software and DTS Studio Sound™ allows you to clearly hear all the important details, even if everyone around you didn’t have your meeting penciled in to their calendar.

Your next great business decision is a click away

You don’t have time to spend hours deciding which notebook PC your team needs. With the ability to add tools and features, the security and strength to protect your investment, and the right price to make it the perfect deal, we believe you’ll agree that the HP ProBook 645 is just what you’re looking for.
