Hi, my x230 shuts down instantly when the battery is at 25-30% (around 10Wh).
I tried performing battery gauge reset with no improvements, but I have the suspect that it doesn't run the full charge-discharge-charge cycle since it shuts down (I didn't attend the full cycle so I'm not sure).
I had a wrong "full charge capacity" reading in power manager which I solved switching charge mode in Battery Maintenance from "always full charge" to "optimize for battery health".
The battery firmware update tool is not suggesting an update, so I'm apparently out of options.
Thanks in advance for any help

up. The battery has 13months.
now it dies suddenly when battery level is reported as high as 40-45%
I'll try re-calibration again tonight..

It sounds like your battery is nearing the end of its useful life.
