T450s Laptop (ThinkPad) - Type 20BX - Battery 1 has failed due to normal wear. How fix this?

2019-11-19, 19:48 PM

Hello!

Lenovo Hardware Settings Notification reads: "Battery 1: The battery has failed due to normal wear. The battery cannot be charged. Replace the battery." Ran Lenovo Online Diagnostics and it didn't find anything. Warranty is over btw.

 

I have noticed decreased performance and random shutting off of computer.

Right now they're reading

 

Battery 1: 96% not charging

Battery 2: 66% and charging

 

Question: Is battery 1 the internal? What part would I order? How do I know if the external one is having issues as well? Could there be another problem here instead?

 

Thank you!

Solved! See the solution

I don't have that model to check but I believe battery 1 is the internal one.  Here is the parts list:

https://download.lenovo.com/parts/ThinkPad/t450s_frubom_20160115.pdf.

 

The laptop is probably 4 years old so it is possible both batteries have failed.  I cannot be sure without seeing it, but it seems most likely because of the slow-down and shut-offs.  If you want to open the case to swap or remove the internal battery, boot into the BIOS first and disable the internal battery.  It stays disabled until you plug in the AC adapter.

 

Encompass is the parts outlet for Lenovo in U.S.  I looked at https://encompass.com/

 

I entered the first internal battery from the parts list, 45N1113, and found this:

I entered the first external battery,45N1127, and found this: https://encompass.com/item/10692379/Lenovo/45N1127/

 

The external battery I entered is 3-cell.  There are also 6-cell batteries listed.

I have the T460, which is similar to the T450/s.  Battery 1 is the internal battery.  It's bit of a pain to swap out and very difficult to find a genuine battery vs an aftermarket one.  The aftermarket batteries have a 50:50 chance of working and/or lasting.

Would there be any issue if I don’t replace the built-in battery? I have same error for battery 1.  Thinking if necessary to change since it’s another cost again.
External battery is brand new that just recently purchased.

You should remove the internal battery if it is bad.  Sometimes they start to swell up and make a mess if they are sick.  No internal battery is OK.
