#LENOVO PRIVACY GUARD SHORTCUT UPDATE#
Update firmware to avoid visual freeze at boot Modem may need cdc_ncm prefer_mbim=N to enable data. Requires noapic or intremap=off to boot reliably Use acpi_sleep=nonvs for resume issues, acpi_osi='!Windows 2012' for brightness control issues.
It is possible to hotswap a ultrabay by just releasing the UltraBay eject lever or pressing hotkeys such as Fn+F9. Ultrabay was IBM's, now Lenovo's name for the swappable bay. Moreover, on some new models, tpacpi-bat is not able to persist the threshold settings while the laptop is powered off (i.e., if laptop is on AC when powered off, the battery will ignore settings set via tpacpi-bat). As a result, tpacpi-bat is not needed anymore (see also here). Note: Since kernel 4.17, newer Thinkpads can leverage the natacpi API (part of the thinkpad_acpi kernel module) via TLP.
