HP ProBook laptops are a popular choice for business and productivity due to their robust build and reliable performance. Models like the HP ProBook 650 G2, 655 G2, 450 G3, 650 G3, and 655 G3 have served countless users diligently. However, like any heavily used component, the keyboard can sometimes encounter issues, ranging from sticky keys to complete non-responsiveness.

When your HP Probook 650 655 G2 450 650 655 G3 keyboard not working correctly, it can bring your workflow to a grinding halt. While sometimes the problem might be software-related or a simple fix, often a physical issue necessitates a replacement. Understanding the potential causes and the process for HP Probook 650 655 G2 450 650 655 G3 keyboard replacement is crucial for restoring your laptop's full functionality.

Common Reasons for HP ProBook Keyboard Failure

Several factors can lead to keyboard problems on these ProBook models:

1. Physical Damage: Dropping the laptop or striking the keyboard surface can damage the internal membrane or connections.
2. Liquid Spills: One of the most common culprits. Liquid can short out circuits under the keys, causing erratic behavior or complete failure.
3. Wear and Tear: Over time, frequent typing can wear out the key mechanisms or the underlying circuitry.
4. Dust and Debris: Accumulation under the keys can make them sticky or unresponsive.
5. Software/Driver Issues: Less common for complete failure across the board, but can affect specific keys or functions.

Troubleshooting Before Considering Replacement

Before you jump to replacement, try these troubleshooting steps if your HP Probook 650 655 G2 450 650 655 G3 keyboard not working:

• Restart Your Laptop: A simple reboot can resolve temporary glitches.
• Check Keyboard Settings: Ensure settings like Filter Keys or Sticky Keys aren't accidentally enabled in Windows Accessibility options.
• Update/Reinstall Keyboard Drivers: Open Device Manager, find "Keyboards," right-click your keyboard device, and select "Update driver." If that doesn't work, try uninstalling and then restarting the laptop to let Windows reinstall it.
• Run HP Support Assistant: This utility often has diagnostic tools that can test hardware components like the keyboard.
• Test with an External Keyboard: Plug in a USB keyboard. If the external keyboard works perfectly, the issue is almost certainly with the laptop's built-in keyboard hardware. If the external keyboard also doesn't work, the problem might be with the USB ports or the operating system.
• Check in BIOS: Access the laptop's BIOS settings (usually by pressing F10 or Esc during startup). If the keyboard works within the BIOS, the issue is likely software-related within Windows. If it doesn't work in BIOS, it's a hardware problem.

When Replacement Becomes Necessary

If troubleshooting fails and the keyboard still doesn't function correctly (e.g., multiple keys are dead, liquid damage occurred, physical damage is evident, or the problem persists even in BIOS), HP Probook 650 655 G2 450 650 655 G3 keyboard replacement is likely the solution.

Finding the Correct Replacement Keyboard

These specific HP ProBook models (650 G2, 655 G2, 450 G3, 650 G3, 655 G3) share similar chassis designs, but their components, including keyboards, can vary slightly based on features like backlighting, keyboard layout (US, UK, etc.), and specific laptop configuration.

Crucially, you need to identify the exact part number for your specific laptop model configuration. Common keyboard part numbers for these series include:

• 841137-001: Often associated with US layout, backlit keyboards for certain G3 models (like 650 G3/655 G3).
• 841136-001: Frequently corresponds to US layout, non-backlit keyboards for certain G3 models.
• 831021-001: A part number often found with US layout, backlit keyboards for the G2 series (650 G2/655 G2).

Note: These are just examples of common part numbers. Your specific laptop's required part number might differ based on region, layout, and whether it has backlighting or not. Always verify the correct part number for your machine.

How to Find Your Specific Part Number:

1. Check the Old Keyboard: Often, the part number is printed on a sticker on the back of the keyboard itself. This requires some disassembly.
2. Check the Laptop's Service Tag/Serial Number: Use the HP PartSurfer website or contact HP support with your serial number. They can identify the original parts shipped with your system.
3. Consult the Service Manual: HP provides detailed service manuals for their business laptops. Searching online for the service manual for your specific ProBook model (e.g., "HP ProBook 650 G3 Service Manual") will list compatible parts, including keyboard options and their part numbers.

Purchasing a keyboard with the correct part number ensures compatibility with your laptop's connectors, screw mounts, and features like backlighting.

The Replacement Process: DIY vs. Professional

Replacing the keyboard on laptops like the ProBook G2/G3 series is generally not a simple lift-and-replace job. Often, it requires significant disassembly, potentially involving removing the base cover, battery, optical drive (if present), and sometimes even the system board to access the keyboard latches or screws from underneath.

• DIY: If you are comfortable with laptop disassembly, have the right tools (small Phillips head screwdrivers, plastic spudger), and can follow a service manual precisely, you might attempt the replacement yourself. However, proceed with caution, as incorrect steps can cause damage to other components or the laptop chassis. Videos on platforms like YouTube demonstrating the specific model's disassembly can be very helpful, but always prioritize the official service manual.
• Professional Service: For most users, especially those unfamiliar with laptop repair, seeking professional service is recommended. A qualified technician has the experience, tools, and knowledge to perform the replacement safely and efficiently, often preventing accidental damage that could occur during a DIY attempt.

Conclusion

A malfunctioning keyboard on your HP ProBook 650/655 G2, 450 G3, or 650/655 G3 doesn't have to mean the end of your laptop. By systematically troubleshooting issues and, if necessary, proceeding with a HP Probook 650 655 G2 450 650 655 G3 keyboard replacement, you can restore your device's usability. Remember to identify the correct part number using resources like the service manual or by inspecting the old keyboard, potentially looking for numbers like keyboard part numbers 841137-001 841136-001 831021-001 that align with your model. Whether you choose the DIY route or professional service, replacing the keyboard is a viable solution to get your ProBook back to working efficiently.
