Can you borrow an external CD, Natacha?  Someone should have one ..

I don't think that's such good advice, though I appreciate the fear of 
doing it wrong.  Updating the BIOS and EC on my T23 required Windows or 
DOS; it had win2k installed so I went with that, but was led to believe 
that a FreeDOS bootdisk would do the job.  Later models (T43 and such) 
also had a bootable CD image available, that could most likely be made 
to work from a bootable memory stick, though I haven't tried that.

Well you could check BIOS/EC upgrade notes to try seeing if any of the 
issues fixed may be relevant, but there have been many issues and PRs 
fixed by nothing but a firmware upgrade, so I wouldn't skip that.
