The HP Envy Desktop TE02 is a tower computer with Bluetooth provided by a small card or a USB adapter, and when Bluetooth devices will not connect it is usually a driver, a service, a missing radio or interference, since a desktop has no lid antenna and sits further from the devices. First check that the computer has Bluetooth at all: open Settings, Bluetooth and devices, and look for a Bluetooth toggle.
The checks in more detail
If there is none, open Device Manager and look for a Bluetooth entry; some configurations have no radio, and an inexpensive USB Bluetooth adapter solves it. If it has one and the toggle is off, switch it on and make sure Airplane mode is off. Restart the computer, remove the device from the list and pair it again, with the device in pairing mode and within a meter of the tower. Open Device Manager and look at the Bluetooth entry for a yellow mark.
Uninstall it, restart and let Windows reinstall the driver, or install the Bluetooth driver from HP's support page for the TE02 or from the radio's maker. Check the Bluetooth Support Service in the Services list: it should be running and start automatically. Because the tower often sits under a desk, behind metal or a monitor, the signal can be weak: move the adapter to a front port or use a USB extension to bring it into the open, and keep it away from USB 3 devices and external drives, which create noise at 2.4 GHz.
A wireless router nearby on 2.4 GHz also competes, so try the 5 GHz band for Wi-Fi. Update the BIOS and chipset drivers. For a keyboard or mouse that lags, replace the batteries and check the dongle's range. Test with a second device to see whether the computer or the accessory is at fault. If Bluetooth disappears from Device Manager after every step, the card may need replacing, and HP support can advise.
