Subject: battery drains after shutdown
Date: Sat, 14 Feb 2015 15:38:24 +0800	[thread overview]
Message-ID: <1423899504.11560.128.camel@rzhang1-mobl4> (raw)

Hi, Bryan,

I've got a bug report that battery drains after shutdown.
https://bugzilla.kernel.org/show_bug.cgi?id=47811

The problem is that
1. Battery drains after shutdown
2. setting HWCLOCKACCESS=no in /etc/default/hwclock, which bypasses
the /sbin/hwclock --systohc  operation during shutdown, solves the
issue 
3. setting HWCLOCKACCESS=no, but enable RTC wakeup explicitly, the
battery drains similar power
4. I did a google search and found that there are some pages mentioned
that /sbin/hwclock --systohc may enables RTC wakeup unexpectedly.

So do you have any idea about this problem?

BTW, it would be great if you have an account in bugzilla.kernel.org.

thanks,
rui
