Tomorrow the T460 (20FM0033XS) will arrive and I want to ask whether this notebook is among Linux-supported (Ubuntu). Can I do a dualboot or replace Windows with Ubuntu (17.04)?
Solved! Go to Solution.

I have the T460p and ubuntu 17.10 works absolutely fine. You will need to disable Secure Boot to boot into Ubuntu if you need third party software (and you will).
Make surey you install tlp and tpacpi module for your laptops battery life. Dual boot with W10 here is fine too.

Hi, thanks for your replay.
I replay to you right now from my new Thinkpad. I'm so happy
I have installed ubuntu 17.04 now and it works perfectly.
Can you pleas write me more about tlp and tpacpi?
How can I install it? How should I configure it?
If you have time, please write to me.

To install tlp,
sudo apt install tlp tlp-rdw
To install tpacpi-bat (the kernel module to read the battery info),
sudo apt install acpi-call-dkms
At this point you will be promted to disable UEFI Secure boot if you haven't done already. You cannot run acpi-call-dkms with Secure boot.
sudo tlp stat
sudo tlp enable
You can edit /etc/default/tlp (you need to do some reading for this) but mainly if you keep your laptop on AC power you'd want to set the battery charge limit to 80% so that you don't wear it. For this look for:
and set them as above. If there is a # symbol in front of these statements, please remove it to enable them.
You can override these settings if you need a full charge with:
sudo tlp fullcharge

thank you so much for this guide!
Unfortunately it doesn't seem to have an effect on my machine.
Lenovo T460, runing Ubuntu 18.04.
I followed all the steps and doubble checked if I missed something, but it still charges until 100%
Another issue I have, and I am not sure if it correlates, is that at times plugging my machine on, won't charge at all.
I have to shut it down, remove the battery, hold down the power button for 20sec, but battery in, restart and then it charges again.
(this doesn't have to be solved here, but I thought I mentioned it )

Has tlp installed properly?
When you do:
sudo tlp stat -b
do you see the thresholds set?
Is tlp running?
sudo tlp start
Is the battery % reported correctly in other apps?
See if tlp can control charging and discharging your battery.
With AC connected do:
sudo tlp discharge
Keep in mind that (when it works) if the % is more than the lower threshold, the status will be connected not charging.
Discharge to below the lower threshold and do:
sudo tlp fullcharge.
See what you get.

thank you so much for your fast reply
sudo tlp stat -b
--- TLP 1.1 -------------------------------------------- +++ ThinkPad Battery Features tp-smapi = inactive (unsupported hardware) tpacpi-bat = inactive (kernel module 'acpi_call' not installed) +++ Battery Status /sys/class/power_supply/BAT0/manufacturer = SONY /sys/class/power_supply/BAT0/model_name = 45N1111 /sys/class/power_supply/BAT0/cycle_count = (not supported) /sys/class/power_supply/BAT0/energy_full_design = 23200 [mWh] /sys/class/power_supply/BAT0/energy_full = 20150 [mWh] /sys/class/power_supply/BAT0/energy_now = 3260 [mWh] /sys/class/power_supply/BAT0/power_now = 24362 [mW] /sys/class/power_supply/BAT0/status = Charging Charge = 16.2 [%] Capacity = 86.9 [%]
So I don't see the thresholds set?
tlp is running.
Although I haven't figured out, if I need to insert that command somewhere, so I don't have to start it manualy everytime.
with the command to discharge I get this error
Error: ThinkPad battery features not available.
Also my battery charging problem is getting clearer,
once unplugged I have to restart my system in order to charge it again.
You don't happen to guess, in which direction I might be looking here best?
(Problem rather with Laptop/Charger/Ubuntu/...)
