If your laptop have bluetooth then you should be able to pair the Marvel HA with it.
If your laptop can not find the hearing aid, then it could be that you have two Bluetooth devices connected to your Marvel aids. e.g. Hearing aid connected to smartphone.
If that is true, you need to disconnect Bluetooth on one of those devices. Only one device connected to your aids at a time.
So please disable bluetooth on the smartphone first , to disconnect the hearing aids from the phone, then pair and connect the hearing aids to the laptop.

On Win10 go to Settings > Devices > Add Bluetooth or other device > Bluetooth
then close both battery doors on the Hearing Aids.
You only need to pair one Bluetooth device (Audio) and this should have a symbol like this
During the pairing process only the one BT Audio device with this symbol is needed !
THIS IS THE CRITICAL PART
After closing the battery doors, the computer should find the hearing aids in the “Other devices” area.
Then wait …
After a short wait, it will give the option of pairing them as the Audio device with the symbol you see above, in the Audio section.
Then click on the new Audio device and hit “Connect”.
If the sound output of the laptop is still not going to the hearing aids then go to the Task Bar and left-click on the speaker symbol and the ^ symbol to open up audio device options. Selectg the hearing aids from the selection.
