Memory Errors
Memory errors on the system display the new 2 - Amber, 3 - White failure code. If all memory fails, the LCD does not turn on.
Troubleshoot for possible memory failure by trying known good memory modules in the memory connectors on the bottom of the system
or under the keyboard, as in some portable systems.
