[FDE] tablets again

[robin]

I found out the hard way that tablets and fde are not a good combo. We 
would like to use pre-boot authentication with a password on tablets in
tablet mode (no keyboard). Ideally this would not involve fingerprints.
if we HAVE to I guess we could use usb tokens. I am finding that this is
not a piece of cake and it may be that there is NO product in existence
that can handle the scenario of entering the id/password via a screen
keyboard. Is there?

The possible choices for laptops are gateway m285e and lenovo x60. (No 
levono does NOT provide fde in the "client security center" as they 
apparently did in the x41 despite being incorrectly told that they do by 
a sales rep. They say that it can be done with an additional product 
from utimaco but I can't find anything that describes how that works 
anywhere. If how it works is via the fingerprint reader then forget 
that. [I personally have never been able to get my fingerprints to pass 
one of those on any vendor's model so I'm definitely not going to try to 
get users to do it over the phone.)If it works via usb smart card then I 
guess we have to deal with the losing tokens scenario which I'd really 
rather not deal with :-(
