Running Ubuntu is draining the battery very fast #61

Closed ghost closed 5 years ago

ghost commented 5 years ago

Im just using google chrome in ubuntu, my battery will be drained about 3 times faster than im using google chrome in windows 10.

For example, running google chrome in ubuntu took 1 hr 15 min to completely drained the battery but running google chrome in windows 10 took about 4 hr..

How to solve this issues, as i installed tlp in ubuntu.

kfechter commented 5 years ago

Do you have the nvidia drivers/ nvidia-prime packages installed.

does the command prime-select query return output? If not, the machine will constantly be running the nvidia GPU and the nvidia gpu will give between 1 and 1.5 hours of battery life.

ghost commented 5 years ago

the returned out was NVIDIA

ghost commented 5 years ago

Okay, i switch it back to intel using sudo prime-select intel, let me observe the battery life and usage.

kfechter commented 5 years ago

I would do a reboot after the prime select just to be safe. Sometimes it doesnt always switch immediately even though it is supposed to.

ghost commented 5 years ago

Yes, i did a reboot. But what is the correct way of install TLP, is using this command? sudo apt install -y tlp tlp-rdw, as im new to ubuntu, not quite sure how to setup tlp.

kfechter commented 5 years ago

Yeah. That is correct. I've installed tlp, but I've never really figured out how to configure it.

kfechter commented 5 years ago

what is the output of the following command cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

ghost commented 5 years ago

Sudo prime-select intel will retain battery life, thank you @kfechter

@liho00 after using the given command, my external monitor is not detected. Please help.

kfechter commented 5 years ago

In intel mode, you cannot use external monitors. Only in nvidia mode as the display outputs are attached to the nvidia gpu

dush1729 commented 5 years ago

@kfechter thanks for the quick response. Now the issue I'm facing is if I revert back to prime-select nvidia then I get blank screen after login and if I use prime-select intel then I'm able to login and change brightness but same external display issue exists in this mode.

I'm facing this issue Lenovo legion Y540 with Nvidia rtx 2060 graphics.

kfechter commented 5 years ago

Interesting. Now I'm wondering if the drivers dont fully support the RTX 20 series. I dont have any machines that I can test this on unfortunately.
