Many dealers in the Philippines are not aware of this problem or don't care enough to keep themselves informed, this problem is from 2019 up until 2024.
If you have stock of these models you better read on. You need to update the firmware immediately, if you have not already done it.
Or you will end up with systems that can't be repaired and Lenovo don't care about out of warranty laptops. You should also contact all the customers that you sold these models to and make sure the Firmware get updated or you might end up with a lot of angry people who want refund!
