Cambridge Silicon Radio CSR 4.0 USB Bluetooth Dongle I had to solve this problem once and for all.įrustrated, I headed to Amazon and set out to find a new Bluetooth 4.0 USB dongle. I recently had a renewed interest in training courses, so I bought an awesome set of Hiearcool L-1 Bluetooth Headphones. Until a few days ago, I lived with this problem because it was not a big deal. Devices would stop working, and I would need to remove them from the system and add them again along with several other tap dances to keep things working. Unfortunately, the Bluetooth 3.0 on the Thinkpad was flaky. Life was good until about two years ago when I decided I wanted to regularly pair my Amazon Tap, Sharkk Boombox, and a pair of Jabra Bluetooth earbuds to the system. When it was new from the factory, I installed a Samsung 500Gb SSD to eliminate the weakest link, a Western Digital mechanical hard drive. NOT Supported: home theater or automotive systems.I have an older Lenovo Thinkpad W520 notebook computer running Windows 10 Professional that, for the most part, has been an ultra-reliable workhorse.
