Our best recommendation is to take the engineering debug analysis we have been able to provide above and contact Lenovo to determine if they will conduct further testing to determine the boot/power up setting that is preventing the BT from being enabled. Please be aware that our card was never validated on this platform since it’s not an approved platform combination from Lenovo, and so they may not see this issue as one that needs to be resolved. -- You are receiving this mail because: You are the assignee for the bug.
