To turn on your HP wireless keyboard, first make sure it has power by installing fresh batteries or charging it, then locate and use the power switch or button. Most HP wireless keyboards turn on with a simple toggle or press, and some models power up automatically as soon as batteries are inserted.
How to turn on your HP wireless keyboard: first steps
Before anything else, check that your keyboard actually has power. Open the battery compartment on the back or bottom of the keyboard, you may need a coin or small screwdriver depending on the model. Remove any plastic battery tabs you find inside, as these are placed there to prevent the device from receiving power during shipping and must be pulled out before use. Install fresh AA or AAA batteries, making sure the positive (+) and negative (−) ends align with the markings inside the compartment. If your keyboard is a rechargeable model, skip the batteries and instead connect the microUSB end of the charging cable to the keyboard and the USB end to a computer's USB port or a USB charging device. Let it charge until the battery indicator shows sufficient power before proceeding.
Find and use the power switch or button
Once power is confirmed, look for the power switch on your HP wireless keyboard. It is typically located on the side or bottom edge of the keyboard, often marked with an "ON/OFF" label or a power symbol (a circle with a vertical line). Slide the switch to the "On" position. For models that use a button instead of a slide switch, press and hold that button until the keyboard responds. While holding it, watch for an LED indicator light to confirm the keyboard is powered on and ready. If your keyboard has a power button, press it and wait for the LED to respond.
Keyboards that turn on automatically (no power switch)
Not all HP wireless keyboards have a physical on/off switch. Some models, such as the HP 510, power on automatically as soon as batteries are correctly installed. If your keyboard lacks a visible switch or button, simply insert the batteries with the correct polarity and the keyboard will activate on its own. No further action is needed, just proceed to connecting it to your computer.
Connect your keyboard to the computer
With the keyboard powered on, the next step is establishing a wireless connection. There are three connection types you may encounter: a USB receiver (dongle), Bluetooth, or an HP Unifying Dongle. For USB receiver models, plug the dongle into an available USB port on your computer; the keyboard should automatically pair within a few seconds. For Bluetooth keyboards, ensure your computer has Bluetooth capability and that Bluetooth is enabled in your operating system settings, then put the keyboard into pairing mode by pressing and holding its Bluetooth button until a light blinks. For HP Unifying Dongle models, turn off the keyboard, plug the dongle into the computer, press and hold the pairing button on the dongle for at least 2 seconds until its white LED blinks, then turn on the keyboard and press and hold its multidevice channel button for at least 2 seconds. If the keyboard still isn’t responding, you may need to turn on a wireless keyboard by checking its power switch and battery level first.

Troubleshooting: keyboard won't turn on
If your keyboard still won't power on, work through these checks in order. First, open the battery compartment and verify the batteries are oriented correctly, the + and − symbols must match the diagram inside. Remove any plastic tabs you may have missed, as these completely block power delivery. If your keyboard is rechargeable, reconnect it to a USB power source and confirm the charging indicator lights up; a completely drained battery may need several minutes before the keyboard responds. Next, ensure the USB wireless receiver is firmly plugged into an available USB port on your computer, try a different port if the first one doesn't work. Move the keyboard closer to the receiver, ideally within 30 cm (1 foot), and remove any interfering objects like speakers, TVs, or cordless phones that could weaken the wireless signal. If the keyboard still doesn't turn on, try replacing the batteries with a fresh set even if the old ones seem fine, as weak batteries can prevent the power switch from engaging properly.
