Problem
Description
Memory modules are detected, but a memory power failure has
occurred.
Troubleshooting
Steps
• If two or more memory modules are installed, remove
the modules, then re-install one module and re-start
the computer. If the computer starts normally, continue
to install additional memory modules (one at a time)
until you have identified a faulty module or reinstalled
all modules without error. If only one memory module is
installed, try moving it to a different DIMM connector
and re-start the computer.
• If available, install verified working memory of the
same type into your computer.
