I have been using various linux distros on acer chromebook plus 514 - craasneto - with the wonderful full firmware by mr chromebox.tech . i have been getting random battery critical error on all the linux distros I tried - for few seconds battery shows empty, then battery returns to correct percentage, I have turned off the shutdown on battery critical option , else the chromebook shuts down at the battery critical message.
Currently I am mostly using pop os and mint linux , in pop os once I get the battery critical error there is a continous warning sound till chromebook is shutdown. I have a doubt whether this is related to the no battery displayed acpi issue in windows disussed in this thread - here
@mrchromebox - kindly look into this battery critical issue when you have time. Thanks a ton for all the great work.
On craasneto it randomly happened in various distros - popos, mint, fedora , cachy os, manjaro . Dont know whether its an issue with my particular device. on other distros turning off shut down when battery critical helps. But on pop os the warning sound remains even after warning disappears. shall try to get some logs when it happens again.
Right now while using pop os the battery critical error popped up again. as you can see from the screeshot battery is at 34 percentage. The warning sound remains till i reboot. not finding any related messages in dmesg, any other place to look for logs? @MrChromebox
