Released as the IBM Personal Computer XT, or PC/XT, the 5160 is based around Intel's 8088 processor featuring 8-bit ISA slots for expansion cards. It came with one 5.25" floppy drive, and one 5.25" full height HDD most commonly 10MB. The PC/XT used a 130W power supply.
| Preliminary Information | |
|---|---|
| Leak Risk | Low |
| Batteries | None |
| Destructive Entry | No |
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.
The PSU case has security screws in addition to the standard hex/flat screws
Once the PSU is opened, there are four screws that need to be removed to fully access the main board, in addition to an earth wire and connector from the input board
There are three sub-boards attached to the main PSU board that generally do not need to be removed to access all the caps
