Lenovo ThinkPad Z16: Firmware update supposed to solve reboot-problem
High quality components, AMD Ryzen 6000 - sounds like a winning combo in the year 2022. A laptop like this is the Lenovo ThinkPad Z16 G1 (available from Amazon, affiliate link), a multimedia laptop with a 16 inch screen, slim exterior, premium materials and powerful AMD Ryzen 6000H series chips. Despite this, the ThinkPad only achieved 87 % in our comprehensive review, missing the "Very good" verdict. This was due to an extremely annoying problem: The laptop would just restart itself during use.
Due to this, we were not able to perform our review as normal, and had to request an exchange of the review unit. Our second sample was quite an improvement over the first, but the problem was not completely gone. From time to time, reboots would still occur. Clearly, this was an endemic problem and not a hardware issue with the first unit.
An endemic problem which Lenovo claims to have resolved now. At least, that is what the Readme file for the newest BIOS version 1.24 claims, as the changelog reads "Fixed an issue where computer might restart unexpectedly."
Of course, without retesting, we can not say for certain if the problem is truly solved. So, we ask our readers who own the Z16: Has the newest UEFI-BIOS solved the reboot problem for you?
