Read me now, or save me for later. (in that imfamous Hans `n' Frans tone) :-) Ok, so you have a T1000SE, and you have found how it does not work if you do not have a good battery on the back. You called Toshiba, and suddenly felt woozy. Aftermarket? Shure! $60 for the T1200XE pack (extended life, the only way to go), but there still has to be a better way, the "college student method"! You call a battery store, and discover that the pack is 'sealed' and can not be rebuilt. Then again, you never did listen to the 'no user serviceable parts inside' lables. The plan? Open it, replace the cells, and close it up. Opening: It is sealed, ultrasound welded actually. All you need to do is break this thin joint. Take the pack off of the computer (back up that hardRAM!) and place it so that the metal contact squares are faceing you and up. The part faceing up, or the bottom of the pack, was physically seprate from the rest of the shell. Note that all 4 metal contact squares are attached to this piece. Now get 2 THIN screwdrivers or knives(jewlers screwdrivers work GREAT). Pick a point that is faceing you (so it will not show when the battery is reinstalled) and push a screwdriver in the small crack/seam between the two pieces. Continue to CAREFULLY pry apart the rest of the seam, and remember, the contact squares are comming all together. After having it all opened, make shure to keep the latch and spring (trust me!). Replacement: Call you local battery distrubitor, or Mr. Nicad, or TNR-The battery store (#'s should be in the 1-800 directory), tell them you got it open. Give them the measurements of one of the cells. I believe they are 4/3A 1700mah, and should be about $5 a shot. Mr NiCad does know them as T1000SE cells last I checked. Get 6 of them. Looking at the old pack, replicate it using the new cells, wire, tape, whatever! DO NOT FORGET THE TEMPRATURE SENSOR! The little black thing attached to one of the cells in the original pack is VERY important! After haveing everything hooked up, you are just about done. Close it up: Check that the contact squares do have voltage around what you would expect (5-7.2V). Reassemble the case, and hold it shut however you see fit. Since I use only one pack, having it on the computer holds it together, and makes it easy to show others my hack. If you have 2 or more, scotch tape should help, or even super-glue. But be warned, you might want to open the pack again some time, and super-glue will make that VERY difficult. There ya go! Good luck!
