Thinkpad T400 shows red light on bezel
by Brant from LinuxQuestions.org on (#6DDE6)
This is an elderly Thinkpad that I keep as a spare or a loaner. Last week I was asked for it, so I installed the current crop of updates for Linux Mint.
Soon after I delivered it, they told me that they were unable to log-in; when I checked, I too was told 'Invalid password', so I simply took it home and reinstalled Mint, and for the moment it is running happily enough.
I did notice that while I was trying to log-in, and while the re-installation was proceeding, that a red light had appeared in the top right-hand corner of the bezel (photo attached). When the laptop was restarted with the new installation it did not reappear.
I would simply like to know, what does the light signify? I had never even noticed it was there, and it does not appear on my later model Thinkpad.
Thanks!
