RE: Bios bug: Latitude 7440


I have E5540, which also had keyboard problems. After updating to latest A12 BIOS keyboard problems mostly resolved, but now I am also experience minimum CPU frequency after resuming from sleep state on battery. Funny thing is that I did not had CPU frequency problem before, and it was introduced in A12, which states "Fixed CPU may stay at low speed after resume from standby" in it's changelog!
