System-board error LEDs The following illustration shows the locations of the LEDs on the system board. You might need to refer to this illustration when solving problems with the computer. An error LED is lit to indicate a problem with a specific component. After a problem is corrected, its LED will not be lit the next time the computer is restarted; if the problem remains, the LED will be lit again. See "Diagnostics" in the Problem Determination and Service Guide on the IBM IntelliStation Documentation CD for additional information. DIMM 4 LED DIMM 3 LED DIMM 2 LED DIMM 1 LED System error LED Microprocessor fan LED Product Recovery program The Product Recovery program is on a hidden partition on the hard disk. The Product Recovery program runs independently of the operating system and reinstalls the operating system and preinstalled software. If you are using FDISK, Disk Management, or another utility to reformat the hard disk, you might see the partition where the Product Recovery program is stored. Do not delete this partition; otherwise, the Product Recovery program will be lost. If the hard disk drive, including the partition where the Product Recovery program is located, becomes damaged or if you replace the hard disk drive, contact IBM to order the IBM Product Recovery CD to recover the preinstalled operating system, application programs, and device drivers. See Appendix A, "Getting help and technical assistance," on page 53 for details. 52 IBM IntelliStation M Pro Type 6218: Installation Guide
