Re: W540 BIOS Update?

Due to a miscommunication, the latest BIOS for several ThinkPad systems were accidentally removed from Affected systems are: T550/W550s, X140e, T540p, W540/W541, X1 Carbon 2nd Gen. They have since been restored.


Please note that a security vulnerability fix was included in BIOS v2.28 which will prevent customers from rolling back to v2.27.
