Just got my new T530. I hooked it up to a 4338 dock in the office and use an external keyboard there.
When cold booting the external keyboard does not work during boot up (for example when the dual boot screen is displayed) and even on the logon screen it takes about 30 seconds before the keyboard becomes active.
I tried all the ports on the dock, but the keyboard behaves the same.
Even undocked, when I connect the keyboard to any USB port on the T530 I have the 'delayed' start of the keyboard.
I checked the USB settings in BIOS and they are all enables.
The keyboard is a recent Logitec version.
I had used the same keyboard on my T61 which also was docked in the office and that combination worked just fine.
Any ideas if there is a setting I would need to change?

I encoutered the same problem here with my W530 and the docking station.
If the receiver is connected directly to the W530 everything works immediately but in the dock there is a long delay.
Seems to be the USB part of the dock has to be initialized while booting.
I would also be glad to here of some kind of solution or workaround.

I tried each USB port on the T530 whilst undocked and none worked during the boot process.
My Logitec keyboard is an illuminated one and the 'lights are out' during the boot process, indicating that no power is available on the USB port where the keyboard is plugged in.
I tried another keyboard and its exactly the same. Nothing happens when buttons are pressed.
The power seems to be available about 30 seconds after i get the Windows logon screen. Thats also when the light comes on on my keyboard.
Right after I got the T530 i did a system update, but the BIOS is on the latest version but other drivers were updated.
And regarding the Windows version, its the preloaded one from Lenovo.

Interstingly, the 2nd keyboard i tried was also a Logitec but not an illuminated one. That keyboard did not work either.
But I now just tried my wifes Apple keyboard, which apparantely worked correctly. Tabbing the F1 key got me into the BIOS setup screen.
So it looks like its my Logitec keyboard that is causing the problem.

I am on preloded windows with current BIOS version. According to lenovo update tool all drivers and software are current. Logitech software is also current
If I plug the logitech unifying receiver directly in the laptop all ist working correct, I can access bios and keyboard is working immediately. If I plug it in any usb-port of the docking station keyboard and mouse are delayed.
Keypoard is a Logitech K360 and mouse is Logitech M705.
