ThinkPad X300 Service and Troubleshooting Guide
Your memory is not operating properly.
1. Verify that the memory is installed and seated correctly in your
computer.
It may be necessary to remove all added memories to test the computer
with only the factory-installed memories, and then reinstall the memory
one at a time to ensure a proper connection. For the procedures to
remove and reinstall a memory, refer to "Replacing memory" on page 40.
2. Check for error messages during startup.
Follow the appropriate corrective actions for Power-on self-test (POST)
error messages.
3. Verify that the latest BIOS for your computer has been installed.
4. Verify the proper memory configuration and compatibility including the
maximum memory size and the memory speed.
For details, refer to the instructions in "Replacing memory" on page 40.
5. Run PC-Doctor for Windows.
If you cannot startup Windows, use PC-Doctor from the service partition
on your hard disk drive.
Note: PC-Doctor in the service partition is not available on your SSD
model.
