Toshiba Satellite Pro 400CS/CDT
The Satellite Pro 400CS and 400CDT were the first laptops released in the Satellite Pro 400 Series. The 400CDT also has the distinction of being one of only a few laptops to fit the "perfect DOS gaming laptop" spec, having both a 640x480 TFT screen and a DOS-compatible sound card.

Common Faults & Maintenance
CMOS/Hibernation Battery Leaks
The biggest issue facing the 400 series laptops is the two VARTA NiMH batteries it has inside, located on the left side of the laptop, under the keyboard. One is a 3-cell battery, used for CMOS backup. The second is a much larger 6-cell battery, using double-wide cells, used to keep the laptop alive in hibernation mode when swapping the main battery pack. Both of these batteries are EXTREMELY prone to leaking, and due to the fact that they're located right next to critical components, a very large number of these laptops have been permanently destroyed by these batteries. It is critical that these batteries are removed in any 400CS or 400CDT.
Brittle Plastic
Toshiba's plastic is now extremely brittle. Handle all parts of these laptops with care. Luckily, the hinge mounting design on these laptops is well designed, but I have seen a couple with cracked plastic near the hinges.
