Como este é um dispositivo relativamente recente, ele não possui BIOS legado, mas sim o firmware UEFI. Infelizmente, a UEFI é extremamente complexa e propensa a erros mais estranhos.
Por exemplo, há alguns anos, a Samsung enviou alguns notebooks que poderiam ser lixados ao gravar muitos dados em uma variável NVRAM, veja aqui e aqui :
[...] There's code in the kernel to make this easier on UEFI systems. Whenever a severe error is encountered, the kernel copies recent messages to the UEFI variable storage space. They're then available to userspace after a reboot, allowing more accurate diagnostics of what caused the crash.
That crash dump takes about 10K of UEFI storage space. Microsoft require that Windows 8 systems have at least 64K of storage space available. We only keep one crash dump - if the system crashes again it'll simply overwrite the existing one rather than creating another. This is all completely compatible with the UEFI specification, and Apple actually do something very similar on their hardware. Unfortunately, it turns out that some Samsung laptops will fail to boot if too much of the variable storage space is used. We don't know what "too much" is yet, but writing a bunch of variables from Windows is enough to trigger it. I put some sample code here - it writes out 36 variables each containing a kilobyte of random data. I ran this as an administrator under Windows and then rebooted the system. It never came back.
Certamente não é impossível para a Lenovo cometer um erro semelhante.
É claro que você deve ter certeza de ter a última atualização de firmware instalada.
