Toshiba T1600
Preliminary Information
Release Year 1989
Leak Risk Medium
Batteries Yes, multiple rechargeable that are leaking
Mounting Technology Through Hole, SMD, Sockets
Capacitor Types Aluminum Electrolytic, Tantalum, Ceramic
Destructive Entry No

The T16000 is a 286 laptop with an alps keyboard, dual batteries, 3.5" FDD, and HDD.

Known Issues

Smoke when plugged in

Causes

  • Leaking C5 capacitor shorting resistors?
  • C5 on Power Supply board leaking

    C5 on Power Supply board leaking

  • Resistors on bottom side of PCB under C5 didn't fair well

    Resistors on bottom side of PCB under C5 didn't fair well

Solutions

  • Clean and recap, possibly replace parts on bottom

Recommended Preventive Maintenance

Cause

  • The T1600 contains two internal rechargeable batteries that may begin to leak and cause corrosive damage to PCBs
  • E1 is a through hold mounted 3 cell battery on the mainboard that wasn't yet leaking in my example but could possibly.

    E1 is a through hold mounted 3 cell battery on the mainboard that wasn't yet leaking in my example but could possibly.

  • 4 cell battery connected with cable had corrosion through the entire copper wire and white power beginning to leak from the shrink seal.

Solution

Disassembly Notes

The screen hinge plastic is very brittle and may break
