Introduction

If you’ve owned your laptop for longer than two years, it may be time to replace the battery. Replacing the internal battery in the Lenovo ThinkPad T450 is a little more complex than replacing the external battery. Follow this guide to replace the internal battery in your laptop.

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

Step 1

              External Battery
  • Using your hands, slide the two locking tabs away from each other to release the battery.
  • Slide the battery up and out of the device.
