Status
Power supply
The device, as a portable computer was able to run off a battery pack, an external power supply and an internal power supply, that replaces the battery pack. Obviously, as an 80's system, it contained the infamous RIFA capacitors.
I (denz (overleg)) replaced two capacitors with new ones. One had already failed, the other one was cracked.
Testing the powersupply after replacing the capacitors gave an open circuit voltage of 16.26 Volt (0.01 V above the nominal 16.25). No current and load tests have been done (do we have a load tester for about 80 Watt?)
System
After repairing the powersupply, the computer still failed to start. [user:stoneshop] and denz (overleg) took the device apart to look for visible damage to the parts,
