This is my first post, wish it would've been on a better occasion...
I think my attempt to update BIOS with a "BIOS update bootable CD" method has failed!
My laptop: Lenovo Thinkpad T420, i5 @ 2.5GHz, 4 GB RAM.
My old BIOS infos (taken from Setup before update attempt):
UEFI BIOS Version 83ET52WW (1.22)
UEFI BIOS Date (Year-Month-Day) 2011-03-24
Embedded Controller Version 83HT27WW (1.11)
I intended to update my BIOS to version 1.46 using "BIOS Update Bootable CD" from this link: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS018784
1) I downloaded this ISO image: http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/83uj28us.iso and burned it on a DVD-RW(DVD rewritable) medium.
2) I placed the DVD in my T420 and turned it off, then turned it on, select F12 (boot menu), selected DVD to boot from, and the BIOS update utility started.
3) In BIOS update utility I pressed "1" to read the instructions, then press "2" to update BIOS. I clicked "Y" to confirm and the update operation started. First it said " Now updating... ", then afer about 2 minutes, it said "Still updating ..." and it stucked like this.
So, right now, this message stays on my screen for about 1,5 hours(!!!):
It may take about a few minutes.
<<< CAUTION >>>
Do not turn off the computer during the update.
Do not remove the CD during the update.
Other details (on system setup and current behaviour): AC was continously plugged in before&during BIOS update, battery is OK, no hard disk activity at all, keyboard is(seems) unresponsive, system's temperature is pretty high, but not dangerously high...
Anyone experienced similar problem on T420 or other similar Thinkpad??? How were they solved?
What should I do next?
How long should I wait?
How should I attempt to stop this endless "Still updating ..." ?
SO PLEASE HELP WITH ADVICE OR ANSWERS!
Please ask any additional details, I'll do my best to answer.
This is really urgent for me!
Thank you in advance!

Current situation: same as described in the first post, it's stucked at "Still updating..." for over 9 hours!!
Now it's clear for me that this is a failed BIOS update.
Anyone any advice on what to do next???
Important info: This T420 laptop is in warranty until 2015.
Should I power it off and back on and check what happens?
Should I leave it running and contact a service and try to take it there in this stucked state?
Please write any hints!

Well, all is well when it ends well!
And this was my case too. My T420 is OK!
So, I'm telling the whole story, maybe it will help someone.
Next day after my BIOS update attempt, so after about 12+ hours of stucking at "Still updating", I took the T420 (powered on !) to a local Lenovo authorized service.
A nice guy took over, he quickly realized that all keyboard keys are unresponsive, on short that the laptop is completely frozen.
Then it forced the shutdown using power key (pressing it for ~ 5 seconds). And then it attempt to power it on again. And...it worked!
Laptop and OS powered on as nothing would have happened, aaand ... BIOS was updated to version 1.46! )
The only "dirty" thing was that Embedded Controller Program (ECP) was still at the old version(1.11).
So the service guy burned the bootable CD ISO on another medium and quickly attempted a 2nd try to upgrade.
And ... again ... it worked like a charm!
All operations took way under 2 minutes, and I ended up with a completely updated BIOS (BIOS itself and the ECP).
Why it stucked in my attempt?
I can think of:
- bad DVD-RW medium;
- corrupted ISO image downloaded (btw, are there MD5 sums or SHA1 sums for the ISOs on Lenovo site?)
- any other causes? This thread is open for comments
Again, that's it folks. It seems it's not so easy to "brick" your Thinkpad T420 laptop !

Thank you so much for sharing your experience with us, @scareduser!
I was in the very same situation, and I wouldn't have known what to do if it weren't for your detailed post.
Obviously, I'd have to refer to an authorized service as well.
I encountered an extra obstacle, given that my drives are encrypted. In particular, I had to find a recovery key for the local drive. Eventually, everything turned out just right, so I feel relieved.
Once again, thanks so much, @scareduser. I believe I was just as scared as you were.

If these long boot symptoms, following the BIOS update occur, multiple customers have reported success in resolving them by disabling Intel AMT and setting the security chip, TPM, as active in the BIOS.
Steps to disable Intel AMT and enable TPM settings as below.
