Put Wireless Keyboard into Discoverable Mode

[YogaBoy905]

How can I put a fully charged wireless Bluetooth HP keyboard from an HP Envy 27-b019 All-In-One PC into Bluetooth Discoverable Mode so I can connect the keyboard to other devices like cell phone or non-HP tablets etc.  This is an extra keyboard I acquired from HP support a couple of years back. The computer has since been resold to someone else. There are no printed key caps indicating Bluetooth, no buttons anywhere, I've tried most every key combination and watched every video - without success. This PC is out of warranty, so HP won't answer me directly.  There's very little useful info on the keyboard sticker, except ASSY KBD, BLK HP WRLS BRM+M+RNR MUS US, with several barcodes with text reading DT1851, 609919-001, 859453-001,  CT:BFVKT0D9PAL01G,  (I can't tell what these numbers represent); there's another sticker containing these numbers P/N 869462-001, CT: BFVKR0B, 9PAL01G - again no idea what these numbers represent. I suspect the receiver capability is inside the Envy All-In-One and there is NO DISCOVERABLE mode for the keyboard itself.  Need to know if this is keyboard is for the garbage or can it be repurposed.  Does anyone have a suggestion or knowledge of this otherwise excellent slim design metal keyboard?

Hello
sorry but i think you have usb keyboard, classic
if you don't have the required usb dongle, it can't work, let alone Bluetooth
this is not a   Bluetooth keyboard

you have hp references, but some do not seem relevant

@YogaBoy905 -- is this your computer: HP ENVY All-in-One - 27-b019 PC Product Specifications | HP® Customer Support

I see:  

Premium lifestyle wireless keyboard with volume control
Wireless technology: Two-way 2.4 GHz radio frequency

and:

Optical mouse
Wireless technology: Two-way 2.4GHz Radio Frequency

Neither of these devices use BlueTooth communications.

Both use "Wireless G" protocol, to communicate with the original HP computer that you have sold.

Hello
thank you for confirming what I mentioned :it is not Bluetooth

but

"This is an extra keyboard I acquired from HP support a couple of years back. "

given that it is another keyboard sent by hp, we can not say that it is the same one that equipped the computer ..
There is a chance it would be a similar model, if it was a replacement, but only hp could confirm!
why do you no longer reply to the user here, however!

Given that I've sold the original computer and this is in fact a duplicate of the original keyboard sent to me by HP AND given that I can't make the keyboard work with any device after hours of trying various alternatives, I'm giving up and trashing the keyboard (what a waste) because it's not reusable. I can't confirm or reject if it communicates with the mated computer by wireless-G or not, but I give up. So thanks to all who offered assistance. Bottom line this keyboard whatever it is, only works with the original computer that's it.

There was no USB dongle on the outside of the all-in-one computer. It's possible that the dongle was somehow attached inside the case on the motherboard. Either way, it doesn't exist externally for me to reuse on any other device which renders this nice keyboard useless for connecting any other device. As mentioned in the previous post, I give up. Too much devoted to a keyboard. Thanks for your assistance

@YogaBoy905 --  It's possible that the dongle was somehow attached inside the case on the motherboard. 

I have seen that on an All-In-One computer. Underneath a removable cover on the back, the motherboard has a USB socket, and a USB-to-wireless adapter was connected, to "talk" to the wireless KB/mouse.

Maybe, simpler and cheaper to design/manufacture such a motherboard ?

I hope that you take the "useless" KB/mouse to some "end-of-life" electronic recycling depot, rather than sending it to a land-fill.
