Ensure that you complete an internal device check before
you install or service your system.
To conduct the internal device check, use the following
steps.
- Check for any non-Lenovo changes that were made to the
device.
- Check the condition of the inside of the device for any
metal or other contaminants, or any indications of water, other fluid,
fire, or smoke damage.
- Check for any obvious mechanical problems, such as loose
components.
- Check any exposed cables and connectors for wear, cracks,
or pinching.
