I purchased a BT 4.0 mouse that can also be used az a USB wireless
mouse, using a 2.4Ghz USB dongle. It works fine on my Win10 Lenovo
laptop in either mode, but on my older HP Win7 PC the BT connection
does not work. I wonder if it is because my HP laptop does not
"understand" the BT 4.0 standard or what? Could it be because the BT
4.0 mouse is not downward compatible with possibly an older BT
standard used by my Win7 PC?

Had the same problem with an older laptop with Bluetooth. Would pair up
nicely with speakers, but not with the BT mouse.

There may an updated driver available, but I haven't bothered looking.

In my case, HP lost interest in upgrading its drivers beyond Windows
Vista. But otherwise the thing works great with Win7 and I like its
construction that allows replacing any major component in it with ease.
It's the HP Pavilion model tx-1410us model.

The documentation for this laptop has been removed from the HP
website [1], so you can no longer see the specifications, download
manuals, etc., so we can not determine what Bluetooth version the BT
adapter is.

I've found some other webpages, but they just say 'Bluetooth'.

That brings me to my general advice, not only to you, but to everyone:

When you buy a product, download/save the specifications, manuals,
etc. while you can. You may know the specs *now*, but what in X years
time? What was the SD spec, the WiFi spec, the LAN spec, the Bluetooth
spec, the CPU spec, etc., etc., ad infinitum. And not just for
computers, but for any device.
