Released as the IBM Personal Computer, or PC, the 5150 is based around Intel's 8088 processor featuring 8-bit ISA slots for expansion cards. It could be ordered with two 5.25" floppy drives, most commonly 360k Tandon TM100 models. The PC used a 63.5W power supply.
Known Issues
No power
Causes
- Power supply will not turn on
Solutions
- Power supply must have a load on it to activate
- Recap
Disassembly Notes
The top shell must be tiled up when pulled all the way forward to release.
Watch out for the speaker on the left side when sliding the shell
The top rear screw tab may catch on the PSU and cable (lift rear when sliding avoid)
PSU slides into tabs in bottom shell
When connecting the PSU back to the system the mother board power connectors should have the black wires next to each other.
