- (Fix) Fixed an issue that CPU is frequency stuck.
- (Fix) Fixed out of order idle state under Linux.
- (Fix) Fixed an issue that battery icon show yellow bang when system is waken up from Full Shutdown, which Wake On LAN is AC Only in BIOS Setup.
- (Fix) Fixed an issue that "The connected AC adapter has a lower wattage than the recommended AC adapter which was shipped with the system..." pops up after press power button when Wake on LAN in system BIOS Setup is AC and Battery.
Ok now we're in fun linux world, make sure to do more research (sadly) before doing firmware updates, and choose your version carefully. See
IMO this is not unique to lenovo, more just what we put up with for mushing software freedom onto hardware non-freedom. Repairable though lenovo is, the reality is there's no such thing as a GNU chip / board fabrication plant. Though maybe there should be, lol.
> In an ongoing Lenovo forums thread, there has been a discussion regarding battery drain issues in suspend/powered-off states. Presumably, laptops with AMD Renoir CPUs and relevant hardware are affected. As of now, BIOS firmware version 1.29 is suggested for use, as version 1.30 introduced significant battery drain; the battery loses up to 50% in 2-3 days while the laptop is in suspend mode.
