if you have a Thinkpad, download the latest Lenovo firmware updater, install the updater but don’t run it. In the folder where the updater has been installed, follow the instructions in BIOS_LOGO.TXT using the attached logo (it could do with some anti-aliasing!). It goes without saying, only update your Firmware if you need to, and follow all the Lenovo instructions or you might brick your PC 
Nice! Reminds me that I need to crowdfund a new laptop as this one is 5 years old and overheats a lot!
