A fairly common series of desktops, the Dell Dimension E510, 5100, and 5150 all shared the same LGA775/Socket T Intel 945G Express-based main logic board which feature PCI-e and 64-bit CPU compatibility with full XP support.
Known Issues
- Machine may exhibit boot errors, graphical artifacts, extremely slow boot, and ultimately random shutdowns.
- A number of capacitors on the motherboard will bulge, possibly vent, and ultimately dry out.
- Solution: Replace all known problem capacitors, specifically the United Chemi-Con (NCC) KZG 6.3V 820uF capacitors.
- A number of capacitors on the motherboard will bulge, possibly vent, and ultimately dry out.
Disassembly Notes
These Dell systems are fairly straightforward to disassemble. Simply take note of where all cables are routed. It is advised to remove memory modules, CPU, and CMOS battery (and replace if original) before beginning the repair.
Additional Notes
- The logic board has printed on it "Model: Connolly". There may be additional variants of this board.
- Within a dense cluster of capacitors, one of the 6.3V 1500uF 8mm capacitors is not clearly labeled. Label may not be printed or is under another component. See reference photo for location.
