You are asked to confirm a change in the TPM configuration on an Asus Transformer Book T300LA laptop with a message similar to:
"A configuration change was requested to clear this computer's TPM (Trusted Platform Module)
WARNING: Clearing erases information stored on the TPM. You will lose all created keys and access to data encrypted by those keys.
Press F12 to clear the TPM
Press ESC to reject this change request and continue"
Unfortunately, the keyboard does not seem to respond, the F12 and ESC keys are not working. USB keyboards are also useless.
Turning the device off and on also comes back to this message. There is no way to get rid of this message without confirming or rejecting it.
The root cause of this is that the TPM uses a special restricted startup mode to display this message in which all non-essential devices are disabled. For the Asus T300LA this includes the USB ports, and the wireless keyboard.
Force the laptop to enable the USB ports and keyboard on startup by using the direct USB booting method (Power button + Volume Up key combination).
1. Turn off the device
2. Press the Volume Up button and keep it pressed until the TPM message appears
3. Turn on the device
A small hourglass will appear in the center of the screen, and the text will probably look a bit larger than usual.
The standard wireless keyboard should now be enabled, and you can confirm or reject the TPM message with the F12 or ESC keys.
Note: For this to work you might need to be running BIOS version 206 or newer
hello I have the same problem but the steps in the solution does not solve the problem, maybe my bios is not very up to date ... what can I do, unfortunately I am stuckReplyDelete
I don't think I was running the latest version of the BIOS either. I would suggest to make sure that you are pressing the volume up button before the power button, since the startup times are really tight. Also, you might want to remove any devices attached to the USB port and make sure that the wireless keyboard is charged and turned on.ReplyDelete

I do it as per your instructions , but I can not connect the wireless keyboard . I tried with a USB keyboard but not working .ReplyDelete
I do not know how to proceed
Do you see anything different when you are starting it up this way? The resolution should be a bit different than when starting it normally with just the power button.ReplyDelete
there are other avenues to resolve the problem ?ReplyDelete
I opened a message to asus, which proceed with a replacement :(ReplyDelete
Hello. I have the same problem. Can You help me to solve it. F12 and Esc buttons are not working. What I have to do ?ReplyDelete
Hi. You need to turn your device using the Volume Up + Power button combination. Press Volume Up before the Power button and keep it pressed until the TPM message appears again. You might notice that the screen resolution is a bit different than before. At this moment the keyboard buttons should work.ReplyDelete
I have the same issue and trying the volume up + power button does not do anything.ReplyDelete
Pressing and holding the Volume Up and then pressing the Power button does not do anything different for me (ASUS Transformer 11.6" T200TA). Thanks anyway.ReplyDelete
I have the Transformer and I love it! It's fast, smooth, updates are being released regulary, but the only thing missing is 3G, so I'm using a MiFi. If ASUS manages to release a 3G version in time they'll get my money for sure.ReplyDelete
