W540 BIOS 2.1 Issues

After upgrading to BIOS v. 2.1 I stumble on two issues:


System startup-

The W540 will not start up when on docking station or battery power.

The only way (I found) to start up is by removing it from the docking and connect to AC power.


WI-Fi access-

When the unit is on docking and connected to a network via cable, it automatically turned off the WI-Fi radio. This is not a bad idea… but prior using the WI-Fi it’s required to turn on the radio and re-booting. Only after re-booting the WI-Fi adapter kicks in and the network selector shows the available networks.


Changing the BIOS back from Ver2.1 to 2.05 solved the 1st issue.

The machine runs Windows 7 pro

Re: W540 BIOS 2.1 Issues

Looks like the last update for Intel LAN Adapter  version solved the 2nd problem.
