Processor replacement (trained technician only)

Use the following procedures to replace an assembled processor.

Before you begin replacing a processor, make sure that you use Lenovo proven alcohol cleaning pad and thermal grease.
The processor in your solution can throttle in response to thermal conditions, temporarily lowering its speed to reduce heat output. In instances where a few processor cores are throttled for an extremely short time period (100 ms or less), the only indication might be an entry in the operating system event log with no corresponding entry in the system XCC event log. If this situation occurs, the event can be ignored and processor replacement is not required.
