   This is a basic battery modification or hack for the Toshiba T-1000
laptop which allows you to use AA (alkaline or Nicad) batteries.
 The nicads are preferable since I've found those to last longer, and also
to be rechargeable using the 9 volt DC power brick that is used with the
laptop.

  The main required item is the black, 4 - AA battery battery holder, used
originally for the CMOS battery backup in the early AT's before the new
battery packs (which included nicad batteries) were put out.

               (connection 2)


  Required  Items:
    -----------
 .1    Toshiba T-1000 battery
 .1    4 - AA battery holder  (Radio Shack  270-391)
 .1    small saw or etco blade/knife
 .1    30-35 Watt soldering iron
 .1    Standard rosin core solder
 .1    Piece of small gauge insulated wire
 .1    Screw (same size of that used in the battery compartment but at least
        1/4" of an inch longer.

    The first order of business is to cut the holder in half at the "cut"
point indicated in the picture above.   The saw worked best for me.
  Be careful not to cut the black wire which is represented in the photo above
as "connection 2", unless you don't mind soldering or piecing it back together
later.   You will have to cut "connection 1" and solder a piece of insulated
wire between it.
   At this point you will need your original battery.   First, cut all 4
leads going to the battery as close as you can get to the battery.  Solder
the 2 black leads together with the black lead coming from your new battery
pack.   Solder the 2 red leads together with the red lead coming from your
new battery pack.

 The Modification is complete at this point.

UPDATE: 
 If you have an internal modem installed, please proceed, but ignore section z
 below...
If you don't have an internal modem installed, please skip to section z below.
You will not use the T-1000 battery compartment,but will need 2 pieces of 
cardboard
 to pad the area beneath it 'cause the 2 pieces of the battery holder will
be laid flat.  So a piece of card board beneath and on top of the battery
holders to prevent anything from possibly shorting out either the motherboard,
internal modem, or battery holders.

z.
  Placing the 2 pieces of the battery holder "back to back" will allow them
 to fit in the T-1000 battery compartment.
   The battery lid will not go on unless you replace the screw with one that
 is a little longer.

 Thank you and enjoy....
