Title
Microsoft Surface Laptop 4 15" Battery Replacement
Introduction
Use this guide to replace the battery in your Microsoft Surface Laptop 4 (15").
***For your safety, discharge the battery below 25% before disassembling your laptop.*** This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]].
You'll need replacement adhesive for the battery in order to complete this repair. Strong double-sided tape like [product|IF317-072-5|Tesa 61395] is recommended.
