Preliminary Information
Leak Risk High
Batteries 3 Batteries:

Main battery: Nickel Metal Hydride 12 V 2,400mAH Backup battery: AA sized Nickel Metal Hydride 1.2 V 1,100mAH

Destructive Entry No


Known Issues

Laptop won't power on

The Toshiba T1950 Laptop is known not to power on due to bad caps on the power board, the lower of the two boards in the laptop. When the on button is pressed, it lights up, but immediately turns off.

Causes

  • Bad or leaky caps

Solutions

  • Replace the Caps and clean the board

Disassembly Notes

Almost all the screw are the same thread (m2.5), but vary in length. There are some M2 screws in the display assembly.

The service manual has a complete guide on how to disassemble the laptop (see the link below).


Original Parts

Lower PCB

  • C526, C527, C528 are surface mount caps, can be replaced with MLCC caps.
  • C523 and C208 are on the underside of the PCB
  • C523 and C208 are surface mount and can be replaced with MLCC caps
  • See the service manual for locations, or the Vogons post about this (both linked below)
