I’m trying manjaro for the first time, and I’m trying linux on laptop for the first time. I have used Gentoo on servers for 15+ years, but I have never used linux on my laptops before. I’ve ran into a few issues. Two of them might be related, so I’ll ask about both in this thread.
The laptop is a Clevo L140cu. It was first installed two days ago, and updated.
uname -r returns 126.96.36.199-MANJARO
When selecting hibernate, the screen is shut off, the pc is doing “something” (I’d assume writing ram to disk), then shuts off. When powering on, it boots up like there was a hard powered off. It boots and logs that there are dirty bits on the filesystems. The applications that were running before the hibernate are not running, and when starting they behave like they were killed.
When putting the pc to sleep (suspend) it consumes almost as much battery as iI use it. While sleeping it consumes 3,5% of the battery per hour. This laptop only consumes 4% of battery per hour at the lowest level of screen brightness, but I’d expect power consumption to be significantly less when put to sleep. When put to sleep the wifi disconnects, screen turns off, power led starts blinking, keyboard backlight is switched off. It wakes from sleep by pressing any key on the keyboard, meaning the keyboard is not powered off. According to powertop the power consumption is 2,75w with screen at lowest brightness, wlan on, BT off.
How should I go about debugging these issues? How to find out what is using power while sleeping? I read somewhere that this laptop should only use about 0.2w while sleeping. That’s 1/10th of what I see here.
How could I find out if the hibernate fails on saving or resuming?
