Well, I've updated the BIOS, but it does not change anything. For
updating, I swapped my SSH with an old HDD with the OEM Windows. But
still the result is the same, the value of USB charge is 1, and can't be
changed. Here is the output you asked for:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Title:
can't change usb_charge attribute in /sys/devices/platform/sony-laptop
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am on a Sony VAIO svf43142sn. My laptop has the ability to leave a USB port
powered on even after shutdown to charge other devices. The value of
/sys/devices/platform/sony-laptop/usb_charge is 1, but the USB port is not
powered on. Also when I tried toggling it to 0 it resets back to 1 when I check
again using cat. So I restarted the module sony-laptop with debug flags on.
When I try:
echo -n 0 | sudo tee -a /sys/devices/platform/sony-laptop/usb_charge
these are the curresponding kernel logs, implying that it was a success:
[ 9121.879908] sony_laptop: found handle 0x0155 (offset: 0x07)
[ 9121.881386] sony_laptop: __call_snc_method: [SN07:0x0000000000000107]
[ 9121.881394] sony_laptop: called SN07 with 0x0107 (result: 0x0000)
But if I cat the value of usb charge, the change is not reflected, and I see
this when I dmesg:
[ 9346.202318] sony_laptop: found handle 0x0155 (offset: 0x07)
[ 9346.202489] sony_laptop: __call_snc_method: [SN07:0x0000000000000007]
[ 9346.202494] sony_laptop: called SN07 with 0x0007 (result: 0x0001)
If it matters, when i simply echo 1, I will get this:
[ 9879.675844] sony_laptop: found handle 0x0155 (offset: 0x07)
[ 9879.676878] sony_laptop: __call_snc_method: [SN07:0x0000000000010107]
[ 9879.676885] sony_laptop: called SN07 with 0x10107 (result: 0x0000)
The entire debug message when I restart the module(sony-laptop) is given
here: http://paste.ubuntu.com/11551226/ . I have asked the same as a question
on askubuntu.com. It has got a other information if you need it:
