Yoga 300 battery percent indicator

2016-12-06, 21:01 PM
I have installed Mint Cinnamon 18 (64 bit) on a Yoga 300.  Most things seem to work straight away though it appears as if my battery percent meter cannot actually see the battery and does not show at all.
On the linux Mint forum someone suggested it might be a BIOS issue though I am very wary about messing around with that without clear guidance.  I am not at all experienced with Linux/BIOS/computer firmware.
QUESTION   Has anyone else had any similar problem?
Diagnosis  From the Mint forum someone guided me to try the following terminal commands:
xyz@xyz ~ $ upower -e
/org/freedesktop/UPower/devices/line_power_ADP1
/org/freedesktop/UPower/devices/DisplayDevice

xyz@xyz ~ $ cat /sys/class/power_supply/BAT1/status
cat: /sys/class/power_supply/BAT1/status: No such file or directory

xyz@xyz ~ $ cat /sys/class/power_supply/BAT0/status
cat: /sys/class/power_supply/BAT0/status: No such file or directory
I have also tried this:
acpi -b
...gives no response.
apm --minutes
... gives "No APM support in kernel"
Background stuff:  At the moment its a dual boot with Windows 10, though that's only so I can return to Windows if things go badly wrong with Mint, I don't actually want to use Win 10 if I can avoid it. 
Things that do work well straight away are:
-    Wifi,
-    output sound
-    The touch screen works well as far as moving the mouse and pinch to zoom.
-    The touch pad additionally gives me a right-click context menu in response to a double finger tap, I can't see how to get the touch screen to do the same.
There are minor problems here:
-     The screen doesn't rotate automatically, including for the "tent mode"
-     The manual process to rotate the screen bizarrely leaves the touch sensitive spots for the screen the original way up, i.e. inverted and not usable
-     The realy physical keyboard doesn't deactivate for the folded right back mode - when the keyboard would be face down on a table top
-     The microphone doesn't work with Skype (think there is a solution in sight, haven't got around to it yet)

Re: Yoga 300 battery percent indicator

I've been reading around and think that the problem may be something in BIOS, or some other feature specific to Lenovo.

 

I noticed in the set up utility (called InsydeH20) there is an option that reads "Intel Virtual Technology", it has been disabled up to now. The details read "When enabled, a VM software can utilise the aditional hardware capabilities provided by Virtual Technology".

Can anyone provide more context description for this option?

 

Could this, or anything else relating to setup or the BIOS help with the lack of battery information in ACPI?
