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
