Dell Precision 5820 Tower sleep/wake issues with Dell KB900 Keyboard and MS900 Mouse
I have a Precision 5820 Tower that's been a source of grief with a new Dell KB900 Keyboard and MS900 Mouse (the Premier Collaboration series). All of these items are brand new.
I'm running Windows 11 Pro. I had been using a Logitech Craft Keyboard and MX Master 2s mouse using a Logitech Unifying Receiver plugged into a Dell U2723QE display. The Logitech keyboard and mouse are several years old and I thought I would upgrade and remove the Logitech drivers and just use the Dell Peripheral Manager to make life simple (because I also have a Dell soundbar and 4k Webcam attached to the display).
My first attempt was to configure the KB900 and MS900 using Bluetooth (the 5820 has the Dell WiFi/Bluetooth PCI-E board installed). While both devices functioned this way one thing that wasn't happening was the ability to wake the computer from sleep. I wasn't sure if this would be possible for a non-laptop PC (in the Apple world of course this has been possible with both desktops and laptops forever). I tried all sorts of settings in Device Manager and although at one point both devices appeared as "wake_enabled"when listed with powercfg (and in Device Manager), enabling wake for the devices didn't correct the problem -- and after more exercising of settings they never again appeared with the Power_Management tab or via powercfg. Typical Windows exerience.
Thinking that PCs don't support Bluetooth when accessing the BIOS anyway, maybe I'd give the Secure Link receiver a shot at this.
I inserted the Secure Link receive into the same USB-A port on my display that the Logitech receiver had occupied (and where it had functioned without any problem).
With the Secure Link setup I've been able to wake up my computer from the keyboard. But the weird thing is that after wake, neither the keyboard or mouse are functional. I have to remove the Secure Link receiver and re-install it for the devices to wake up. I don't understand how the keyboard can wake the computer but then become unresponsive as if it has gone back to BLE sleep.
Any ideas to get this working 100% with either Bluetooth (my preference) or the Secure Link receiver? At this point I'm starting to think I'll just return the Dell Keyboard and Mouse and switch back to Logitech which just plain works.

To achieve that, search for mouse/keyboard with receiver that offers dual mode connection, bluetooth and RF. In BIOS mode, RF offers radio connection type, and when operating system is loaded, it switches over to bluetooth connection.

@Chino de Oro I'm not 100% sure what you mean. The Dell Secure Link Receiver that's included with their keyboards and mice uses its own protocol to communicate. The reason that wireless is supported even when accessing the BIOS is because the receiver plugs into a USB port and looks like a wired keyboard and mouse to the PC.
I've very much settled on just returning the KB900 and MS900 (the KM900 bundle). The Logitech Unifying Receiver just works without any fiddling around. I'm hoping that the new Logitech Bolt Receiver works just as well and will probably just get the MX Keys S keyboard and MX Master 3s mouse to replace these Dell peripherals.
It looks like a number of people are watching this thread so I'm going to assume that other people have this same problem with regard to Bluetooth not waking the computer or the Secure Link Receiver waking the computer only to trigger the keyboard and mouse to fall back asleep again (as the computer sits there and waits for input).
I've spent days researching this issue and it's proven difficult to find any information regarding issues with the Secure Link Receiver. There's a lot of advice (all the same advice) regarding Bluetooth and sleep/wake but the repeated walks through the Device Manager settings, reboots, checking BIOS, checking for driver updates, etc., the exercise is a colossal waste of time when with Logitech I just had to insert the several years old Unifying Receiver into an always-powered USB port, enable "Allow this device to wake the computer" in Device Manager for the keyboard and mouse entries labeled "HID Keyboard Device" and "HID-Compliant mouse" and everything just works. The keyboard entry even makes it clear it's a Logitech device (not sure why the mouse doesn't).
