Lenovo E450 Battery Replacement

Lenovo E450 is infamous for its complex internal that does not allow easy access to the parts. If you want to replace batteries, you should disassemble almost everything.

However, at least that is something doable. But if you connect the battery in the wrong way (by not following the right steps), even though the battery is compatible to your E450, the firmware will say that the battery is not compatible, thus reject charging it.

If you want to avoid that issue, you should follow this procedure:

  1. Remove Lenovo PowerManager and its service from the system.
  2. Go to bios, and turn off the internal battery.
  3. Open the bottom panel of your laptop and disconnect the black cable to your motherboard. Then connect AC and boot into Windows. After log-in the system, turn off the power completely.
  4. Change the battery (you need to disassemble your laptop)
  5. Connect the battery black cable to the motherboard
  6. Boot the system
  7. Check if bios is not complaining about your batteries compatibility
  8. Log in Windows
  9. Re-install Lenovo PowerManager

If you have already installed the battery and suffering from the battery incompatibility issue, you can follow the same procedure – but just skip the step #4.
