Lenovo ThinkPad P1 Gen 7 Fans and Heatsink Assembly Replacement

Inleiding

Follow this guide to replace the fans and heatsink assembly in your Lenovo ThinkPad P1 Gen 7 laptop. You can also use this guide to reapply thermal paste.

Both the laptop's fans are attached to the heatsink as one assembly. To replace either fan or the heatsink, you must replace the entire assembly.

If your laptop's fans aren't spinning or your laptop is overheating, you may need to replace the fans and heatsink assembly.

You'll need new thermal paste (regular and viscous) to complete this repair.

For your safety, discharge your battery below 25% before disassembling your device. This reduces the risk of a dangerous fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
