Frequently Asked Questions

Question #1. What is Dell Peripheral Manager, and where do I get more information?

Dell Display and Peripheral Manager (DDPM) is a free Windows application for managing and customizing Dell monitors and peripherals — including keyboards and mice — from a single interface. It is used throughout this article for pairing, firmware updates, and battery status. For download links, system requirements, and full feature details, see Dell Knowledge Base article Dell Display and Peripheral Manager for Windows.

Question #2. What are the system requirements to install DDPM?

DDPM runs on:

• x64-based systems: Windows 10 build 17763 or later (Home, Pro, Enterprise); Windows 11 (Home, Pro, Pro for Workstation, Enterprise, Education)
• ARM-based systems: Windows 11 on ARM (arm64) with Qualcomm Snapdragon X-Elite or X-Plus chipsets

DDPM does not support Windows SE, Windows IoT Enterprise, or Windows LTSC. To check your Windows build, press and hold the Windows key, and then press the R. In the Run box, type winver, and press the Enter key.

Download DDPM directly from the Dell Display and Peripheral Manager download page, or from your device's Drivers & Downloads page on Dell Support. Installation typically takes under 20 minutes; the first launch can take up to 5 minutes while the application initializes.

Question #3. Does Dell Peripheral Manager support Mac?

No. DDPM (the Windows application) does not run on macOS. Mac users who want equivalent pairing, firmware, and customization features should use the Dell Knowledge Base Dell Display and Peripheral Manager for macOS article instead.

Question #4. Do Dell keyboards and mice work on a Mac?

Yes. Dell keyboards and mice function on macOS using standard USB/Bluetooth drivers built into the operating system. The Windows version of DDPM is not supported on macOS — (see Question #3) for the macOS-specific management app.

Question #5. My wireless keyboard or mouse is not working or isn't detected. What should I check?

Work through these steps in order:

1. Confirm you are using fresh batteries, installed correctly (check polarity).
2. Turn the keyboard or mouse on. Most models have an LED that lights when powered on.
3. Plug the USB receiver directly into a USB port on the computer. Do not connect it through a USB hub, switch box, port replicator, or extension cable — these can prevent detection.
4. If it is still not detected, try a different USB port on the computer.

If the device is still not detected after these steps, the issue may be USB radio-frequency (RF) interference (see Question #6 for interference fixes).

Question #6. My keyboard or mouse is laggy, delayed, or erratic. Why, and how do I fix it?

Nearby computers, monitors, docking stations, and other equipment can radiate radio-frequency (RF) noise that interferes with wireless keyboard and mouse signals. To correct it:

• Move the USB receiver farther away from the interfering equipment (for example, a monitor's built-in USB ports or a desktop's rear USB ports).
• Increase the physical distance between the receiver and the source of interference.
• Plug the receiver into a different port or a port on the opposite side of the machine from the interference source.

Question #7. Repositioning the receiver did not fix the interference. What else can I try?

Use a short USB extension cable (available from most retailers) to relocate the receiver away from the source of interference while keeping it connected to the computer.

Question #8. Where can I read more about USB RF interference?

Intel publishes a technical whitepaper on this topic: USB 3.0 Radio Frequency Interference Impact on 2.4 GHz Wireless Devices (Intel, PDF).

Question #9. My keyboard or mouse became unpaired from the computer. How do I re-pair it?

1. Install DDPM if it is not already on your computer (see Question #2 for download links).
2. Open DDPM.
3. Select the + (add device) control in the app (located in the upper-right corner).

4. In the Add device side bar, select Keyboard and Mouse > Wireless receiver tab.
5. Follow the steps as outlined on the Wireless Reciever Connection page.
6. The device will automatically connect to the wireless receiver after a few seconds. If it does not connect, repeat the steps as outlined on the page.
7. Verify the pairing status in DDPM. The main screen will display the paired drvice.

Question #10. How do I update the firmware on my Dell keyboard or mouse?

1. Install DDPM if it is not already on your computer (see Question #2).
2. If the device uses a USB receiver, make sure the receiver is plugged in and the keyboard or mouse is powered on.
3. Open DDPM. Select the gear icon (located in the upper-right corner), select the Updates tab, and then select Check for updates. If an update is available, select the update prompt and follow the on-screen instructions.

If the firmware update fails:

• Keep the device connected for the entire update — do not disconnect it partway through.
• Make sure your computer has a stable internet connection.
• For wireless devices, charge the battery above 20% before updating.
• If prompted during a wireless keyboard update, press the U key twice.
• If prompted during a wireless mouse update, move the mouse or click the left button twice.

Question #11. Where is the USB receiver for my keyboard or mouse?

Depending on your keyboard or mouse the USB receiver could be in several locations (see Figures 1-4 for possible locations).

Question #12. I bought a keyboard-and-mouse combo. How many USB receivers do I need?

Just one. A single USB receiver pairs and operates both the keyboard and the mouse in a combo set simultaneously.

Question #13. I bought a keyboard and a mouse separately, each with its own receiver. Can I use just one receiver for both?

It depends on the receiver (dongle) type.

• If both dongles have the same symbol printed on them: Yes. Use DDPM to add the second peripheral to the existing dongle:
1. Install DDPM if needed (see Question #2).
2. Open DDPM.
3. Plug in the USB receiver, turn on the original peripheral, and confirm it is working and listed in DDPM.
4. Select + (add device) in DDPM (located in the upper-right corner).
5. Follow the on-screen instructions to pair the second device with the same receiver.
• If the dongles have different symbols: No — each device requires its own receiver. To confirm which software and receiver types are compatible with your specific dongle, see the "How do I know which products I have and what software to use?" section of Dell Display and Peripheral Manager for Windows.

Question #14. How do I use the multimedia and F1–F12 function keys on my Dell external keyboard?

See Dell Knowledge Base article How To Use Multimedia and Function Keys on Dell External Keyboards for the complete key-by-key explanation.

Question #15. What is the wireless range of a Dell keyboard or mouse?

Up to 30 feet (about 10 meters), depending on the placement of the USB receiver and any nearby sources of interference.

Question #16. Why is my battery life shorter than I expected?

Published battery-life figures come from Dell's internal usage-model testing; real-world results vary with usage patterns, operating conditions, and other factors. Rechargeable batteries in particular may deliver shorter runtime than standard alkaline batteries. Dell recommends using a reputable, top-quality battery brand. To extend battery life, turn the keyboard and mouse off when not in use.

Question #17. How do I check the battery status of my keyboard or mouse?

Open DDPM and view the device's battery indicator on its detail screen. (Requires DDPM — see Question #2 for installation.)

Question #18. Why doesn't the Caps Lock or Num Lock LED stay on?

This is expected behavior, not a defect. To conserve battery life, the Caps Lock and Num Lock LEDs stay lit for 5 seconds after the key is pressed, then turn off automatically — even if the lock state (Caps Lock or Num Lock) remains active and you keep typing. Pressing the key again re-lights the LED for another 5 seconds.

If DDPM is installed, the current lock state is also shown in the Windows 11 and Windows 10 on-screen display (OSD) that appears when you press Caps Lock or Num Lock, so you can confirm the state at a glance even after the physical LED turns off.

Question #19. How do I clean my Dell keyboard and mouse?

Before cleaning:

• Unplug the device and make sure it is powered off.
• Remove the batteries.
• Keep liquids away from the device.
• Do not use solvents or abrasive cleaners.

For full cleaning guidance, see Guidance for Keeping Your Dell Technologies Equipment Clean.

Question #20. Does a Dell keyboard or mouse require software or drivers to work?

No. Dell keyboards and mice work out of the box using the generic HID (Human Interface Device) drivers built into the operating system — plug it in (or pair it) and it functions immediately. Install DDPM only if you want to re-pair a device, customize buttons/keys, check battery status, or update firmware (see Question #2 for installation).

Question #21. Is there a Dell Service Tag on my keyboard or mouse?

No. Keyboards and mice do not carry a Dell Service Tag. The Service Tag — a seven-character identifier — is used on Dell computers and monitors only.

Question #22. If there is no Service Tag, how is my keyboard or mouse identified? What is a PPID?

Keyboards and mice are identified by a Piece Part Identification (PPID) number instead of a Service Tag. The PPID is a 20-character string plus a 3-character revision suffix; the 20-character portion is the unique identifier regardless of which revision is appended.

Find the PPID on the underside of the device, on the battery cover, or on the label inside the battery compartment.
