Recommended action
1. Verify ROM, reflash if required
2. Clear CMOS memory, reboot
3. Replace system board
1. Clear CMOS memory.
2. Replace system board.
1. Run Setup (F10).
2. Check DIMMs for proper
seating, type, compatibility.
3. Remove DIMMs singularly and
reboot to isolate faulty DIMM.
4. Replace system board.
1. Verify proper memory module
type.
2. Try another memory socket.
3. Replace DIMM with a module
conforming to the SPD standard.
1. Check DIMMs for proper
seating, type, compatibility.
2. Rearrange the DIMMs so that
each channel has the same
amount of memory.
If additional memory was recently
added, remove it to see if the
problem remains.
Check kybd connection or keys.
Check connector for bent or miss-
ing pins. Replace kybd. If 304,
possible system board problem.
Reflash the system ROM with the
latest BIOS image.
No action required.
1. Determine if hard drive is giving
correct error message. Use F2
Diagnostics to run DPS Self-test.
2. Apply hard drive firmware
patch if applicable.
3. Back up contents and replace
hard drive.
Ensure SATA connectors are used
in ascending order. For one
device, use SATA 0. For two
devices, use SATA 0 and SATA 1.
For three devices, use SATA 0,
