Description
The firmware of the Lenovo X13s does not expose
charge_now
orcharge_full
, but the files still exist, sofile_util::pick()
will still choose that overenergy_now
/energy_full
. This leads to the battery module erroneously outputting "0%" at all times. Ifcharge_now
orcharge_full
is read, it will returnENODATA
, so simply reading 1 char and checking the status should determine if the file should actually be picked.Related Issues & Documents
