So my laptop sometimes has no bluetooth, or wifi, or both. A quick reboot fixes it, but idk if the module is actually faulty. I've opened it before, and don't want to buy a replacement chip if this one is just seated poorly. Is there a good way to check. Thanks
Using the correct tools try to disconnect the cables from the socket and reseat them in the socket make just do as the guide but without removing the WLAN card
