Lenovo blocks the VRAM BIOS setting (GPU Memory)
Lenovo blocks BIOS settings to create interference users when repairing and setting up maximum device performance. This reduces the service life of the device and allows the company to sell more devices. For example, the VRAM setting is blocked - the memory size for the video card or UMA. Lenovo deliberately sets a low or very high value and blocks the setting, as well as the BIOS firmware using Security Flash. On the forums, users are complained by massively, but Lenovo assures that this is for their good. So one user lost 2.1 GB of RAM out of 8 GB In essence, Lenovo deceived and sold it a device with less than 6 GB writing in the 8 GB specification. https://forums.lenovo.com/t5/Lenovo-IdeaPad-1xx-3xx-5xx-7xx-Edge-LaVie-Z-Flex-Notebooks/IdeaPad-3-17ADA05-vram-size/m-p/5104113 And further https://forums.lenovo.com/t5/Lenovo-IdeaPad-1xx-3xx-5xx-7xx-Edge-LaVie-Z-Flex-Notebooks/Reduce-amount-of-VRAM-Lenovo-IdeaPad-3-with-AMD-Radeon-graphics/m-p/5055411 Many-many https://forums.lenov...
