Toshiba T1600

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
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.
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
