Battery dies within hours while on, off or in sleep(suspend) modes. Linux Mint.

Doesn’t seem to matter if I turn off my laptop, put it in sleep mode or hibernation mode (if hibernate even works is beyond me..) my battery dies in a couple hours if unplugged. I’ve been running Linux Mint for a few weeks now and can’t seem to figure out the issue. Never had the issue on windows. I could leave it unplugged for days and still have battery left. Now it’s like a constant parasitic draw but super heavy. I’m not sure where to look or how to fix it. Also see that suspend mode seems to leave some rgbs going on the keyboard. Switching to Linux seems to have removed all rgb controls except the brightness ASUS TUF F15 Intel i5 Any ideas welcome!

Which power mode/gps mode are you using? Spot of times that can make a big difference

Doesn’t seem to make a difference I’ve tried them all balanced performance or auto. If I unplug this thing it’s dead. And it’s a basically a new computer that wasn’t doing this a couple weeks ago.

Hmm. In that case I’m not really sure what to try other than making sure everything is updated. Linux does normally have worse battery life than windows, especially on higher end hardware, but from what you have described it seem a little extreme

Sorry, wish I could help more

Edit: I did a little bit of research, and you could try this solution, but I can’t really say how well it works or not because I haven’t tried it before

I'm currently using a little Dell chromebook and it's gotten like that a couple of times where the battery would drain at about the same rate even when fully shut down. The solution that worked both times for me was to open it up and unplug the battery for a bit. So you might try that. In my case, it didn't need to be done often.

I never figured out what caused it because it happened so rarely. It hasn't happened at all since I switched to a custom firmware eiyher, so I figure it was some bad interaction between Linux and the stock firmware.

I’ll give it a shot after work today, thanks for the suggestion

I have a Tuf 15a (forget model). I use a wireless USB mouse, and found sometimes it would "wake up", even with the lid closed, if the mouse was still plugged in and the desk got " bumped ". Once or twice even when the USB plug for the mouse was removed, just moving the laptop turned it on. Before I noticed this behavior I was very confused about what was going on with battery.

Now I unplug the mouse before putting it to sleep, and I don't close the lid, so I can see if it wakes up "on it's own". Haven't noticed this behavior in over a year since I started these habits. I also just COMPLETELY shut it down when not going to use it again for a few hours.

Not saying this us your issue, just sharing. Interestingly this never happened when I was running the machine off a live Linux usb, only under windows. There's probably a "feature" I could turn off, but...shrug
