A few days ago, when I tried to start the computer, I received the following error message: "ACPI BIOS error: could not resolve symbol [\TZ.ETMD], AE_NOT_FOUND ACPI ERROR: aborting method _SB.IETM._OSC due to previous error Bluetooth: hci0: Malformed MSFT vendor even: 0x02 irq 9: nobody cared (try booting with the "irqpoll" option) handlers:[<00000000f27a4891>] acpi_irq Disabling IRQ #9" I was unable to access Ubuntu and had to proceed with a reformat. After doing some research, I learned that this may be a problem with the graphics driver, and I am concerned that I may lose access to Ubuntu again and have to constantly reformat my computer. I would appreciate any assistance in resolving this issue and ensuring that my Ubuntu installation is stable and fully functional. Thank you for your attention to this matter.
