Make it to fails= the resume process.
Everything works fine while plugged in.
If in battery it fails to resume (attached dmesg file). It gets stuck into the
desktop but it's dysfunctional without disk operation.
If I suspend in battery mode and then resume (dysfunctionally) and then plug in
the power supply the disk resumes perfectly and everything comes back to normal.
