Editing Osborne Executive Capacitor Replacement Guide (section)

== Visual Inspection & Failure Signs ==

Before beginning, examine the Osborne Executive’s boards for these common capacitor failure indicators:

* '''Bulging or domed cans''' – especially on the power supply and mainboard filter capacitors.
* '''Leaking electrolyte''' – brown, green, or white crust at the base of capacitors or on the PCB.
* '''Corrosion or PCB staining''' – discolouration or green residue around capacitor leads.
* '''Unstable operation''' – random resets, video distortion, or disk errors may be traced to failing capacitors.

If any single capacitor shows signs of failure, it is best practice to replace '''all''' electrolytic capacitors in the system.
