You can tell the version of Debian by looking at the
/etc/debian_version file.

  cat /etc/debian_version

That will say one of the following:

  5.0.8       -- Lenny point release 8 (current oldstable)
  6.0.1       -- Squeeze point release 1 (current stable)
  wheezy/sid  -- Sid Unstable (daily bleeding edge bits)

No.  There isn't anything particularly special about laptops.  The
installer doesn't ask any questions specific to laptops during the
installation.  It isn't needed.  The device drivers in the Linux
kernel will detect if you have a battery and do the right thing.

You ran this from the BIOS at boot time?  Or you ran it from a
bootable disk?

You said you replaced the disk.  The factory partition existed on the
factory disk.  Your replacement disk did not have this partition.

Grr...  Vendors can be such terrible citizens.  If the disk really
does match the machine then it is probably objecting to the difference
in the size of the disk drive between the old and new.  I have seen
this before myself.

But just the same even if you could run it I doubt it could "fix" your
battery problem.  I think your battery is bad as a hardware problem.
Nothing in software can fix it.

And no directory called something like BAT0?  Then your battery has
fully failed and is not responding.

Yes.

Yes.

The /sys is similar to and a newer interface that is also available in
/proc.  On my machine:

  $ find /sys/class/power_supply/BAT0
  /sys/class/power_supply/BAT0
  /sys/class/power_supply/BAT0/uevent
  /sys/class/power_supply/BAT0/subsystem
  /sys/class/power_supply/BAT0/device
  /sys/class/power_supply/BAT0/power
  /sys/class/power_supply/BAT0/power/wakeup
  /sys/class/power_supply/BAT0/type
  /sys/class/power_supply/BAT0/status
  /sys/class/power_supply/BAT0/present
  /sys/class/power_supply/BAT0/technology
  /sys/class/power_supply/BAT0/voltage_min_design
  /sys/class/power_supply/BAT0/voltage_now
  /sys/class/power_supply/BAT0/current_now
  /sys/class/power_supply/BAT0/energy_full_design
  /sys/class/power_supply/BAT0/energy_full
  /sys/class/power_supply/BAT0/energy_now
  /sys/class/power_supply/BAT0/model_name
  /sys/class/power_supply/BAT0/manufacturer
  /sys/class/power_supply/BAT0/serial_number
  /sys/class/power_supply/BAT0/alarm

No.  But it has everything to do with having a failed battery.
