My guess is that the laptop uses APM which is really old. Debian must have
phased it out, but you can check the packages if there is still APM support
instead of acpi. Otherwise you can check if there is a bios upgrade to
support acpi (they will probably sell it as compatibility upgrade for win2k -
thats how toshiba presented it).

It's a lot of bang for the money, but it's a bit heavy and they save money
where they don't tell you, such as the touchpad, keyboard, screen. A friend of
mine got it just now, we'll see how it holds up.

T61 is a bit old now but still available. Reviews of the t500/t400 seem to be
mixed (especially regarding the keyboard, not sure about the screen).
