Lenovo claims there is no problem with the devices but there are instances when Battery triggers the BSODs. The blue screens had the stop codes WHEA UNCORRECTABLE ERROR and UNEXPECTED_STORE_EXCEPTION.

Temporary fix: Unplug the Battery adapter
Battery is the main reason for Lenovo Thinkpad L490/L590 Blue Screen errors WHEA_UNCORRECTABLE_ERROR and UNEXPECTED_STORE_EXCEPTION and when it is unplugged the problem is automatically fixed. So as a temporary fix, you can remove the charger:
Update BIOS to the latest version
When the BSOD started in 2023, Lenovo fixed the rashes with BIOS 1.30 and 1.31 as reported. As the bug check reappeared Lenovo should care for the issue by releasing a new BIOS update:
- Press “Win + X” and select “Device Manager”.

Change Power options to Maximum performance
Some users write that changing Power options to Maximum performance works in this case and fixes the Blue screen. However, this method is not practical, you can give a try if you like:
- Right click on “Start” and select “Power Options”.
- In the “Power mode” section on Settings, click on drop-down and choose “Best performance”.
Replace the SSD
If anything does not work the last resort is changing the Solid State Drive. However, this is a costly deal and before replacement, you should establish communication with the Lenovo support team. After reaching the conclusion that maneuvering with software can not solve the BSOD, make the decision to change SSD.
We recommend contacting the authentic and official retailer or dealer to replace the hardware.
Generally, UNEXPECTED_STORE_EXCEPTION and WHEA_UNCORRECTABLE_ERROR are two blue screen stop codes related to hardware and software issues respectively. UNEXPECTED STORE EXCEPTION is the result of conflict between third-party programs, incompatible drivers, and system file problems.
WHEA UNCORRECTABLE ERROR usually appears because of glitches in hard drive, overclocked CPU, or memory which Windows couldn’t recover. Therefore follow the above methods accordingly to resolve Blue Screen error in Thinkpad L490 or L590.
