Battery overheating and drain while suspended!

I have a new ASUS ZenBook UX533F with Ubuntu 19.04. Initially, battery life was excellent, heat was low and suspend worked properly.

I was trying to find a way to limit the battery charge to 80% to extend the life of the battery, so:

  1. I installed tlp and tlp-rdw.

However, sudo tlp-stat --battery reported that I could not set thresholds for charging:

natacpi    = inactive (no kernel support) tpacpi-bat = inactive (laptop not supported) tp-smapi   = inactive (laptop not supported) 

Foolishly, I thought that if I could get kernel support for natacpi, I would be able to use this feature, so I did:

  1. sudo apt install acpi-call-dkms – had read somewhere that this would make the feature work.

When I did that, it told me that it needed to “register” something on the BIOS or UEFI (I did not understand what it meant – I saw the word “MOK” somewhere).

It was too late!

Now, my battery life is much lower, my laptop is constantly overheating and it even produces a high level of heat when it is suspended.

I have already verified that the laptop enters suspend:

Oct 03 11:21:15 myuser kernel: PM: suspend entry (s2idle)

Did I ruin my new laptop? Somebody help!!!

Overheating and Fast Fan with Ubuntu 18.04 on Asus X550VX

My notebook (with NVIDIA) is running in abnormally fast fan speed and temp. At first I thought it was the graphic card, then I installed appropriate drivers for my graphic card, still having the same issue. I came across this question about the same issue. I followed the instruction to

  • instal sensor-detect
  • pwmconfig to test each fan
  • /etc/fancontrol to create file
  • add parameter acpi_enforce_resources=lax (I also put pci=nomsi and pci=noaer already)
  • disable turbo boost

However, after booting a few times, my notebook still running at crazy temperature. I tried to run sensors and this is the result :

coretemp-isa-0000 Adapter: ISA adapter Package id 0:  +54.0°C  (high = +100.0°C, crit = +100.0°C) Core 0:        +51.0°C  (high = +100.0°C, crit = +100.0°C) Core 1:        +53.0°C  (high = +100.0°C, crit = +100.0°C) Core 2:        +51.0°C  (high = +100.0°C, crit = +100.0°C) Core 3:        +52.0°C  (high = +100.0°C, crit = +100.0°C) 

I literally can hear the fans running super fast, sometimes randomly when I’m not even running anything (idle). I just recently switched to Ubuntu and and still trying to figure this out. Any advice on how I can overcome this issue ?

Laptop overheating on Ubuntu 18.04

I have Ubuntu 18.04 unstalled on ASUS Rog GL702VM as a second OS. So I have both Windows 10 and Ubuntu. After several days on Ubuntu, I have noticed an overheating, it seemed like my FAN is not speeding up when the temperature is rising. However, when I am working on Windows 10, FAN is automatically adjust speed depending on temperature. Then I made an experiment, I had been working on Ubuntu for 20 minutes, and after an overheating started I switched on Windows. After that, my FAN started adjusting speed.

Ubuntu 19.04 Overheating on Idle

I recently installed ubuntu 19.04 on my laptop (Dell G7 7590). I have faced severe overheating issues. My laptop hits around 71 degrees centigrade even on idle. I’ve tried installing TLP, powertop, laptop-mode, slimbook and nothing seems to have helped so far. I believe the problem is in the CPU running at max freq at all times, but I don’t know how to resolve this.

I tried:

echo '1' > /sys/devices/system/cpu/intel_pstate/no_turbo 

and there has been no change.

I am fairly new to both Linux and the forum so any help will be much appreciated.

Macbook Pro overheating

My 2012 MacBook Pro constantly overheats. The back gets too hot to touch. I’ve done everything I have been told to do that should fix it from resetting SMC and the NVRAM, to taking the back lid off and removing the fan to get all the dust out with an air compressor. I have screenshots attached to show reports from iStat

MacBook thinks it’s overheating when it isn’t?

I have a MacBook (oldish late 2012 retina 13″) that seems to exhibit classic overheating symptoms, except that it isn’t hot.

Under load it tends to shut down after a while, can be turned back on after a few minutes, and can be “fixed” by using iStat Menus to force the fans to always run. (Of course iStat Menus couldn’t help during OS upgrade, so to be able to finish that, I had to put the MacBook in the fridge — that worked.)

However, it’s barely lukewarm to the touch, and according to iStat Menus, none of its temperature readings are high. But when CPU Die temp goes above 70C (CPU Proximity ~55C), it shuts down. I think that should only happen somewhere above 100C, correct? Without the iStat Menus override the fans wouldn’t even start running yet when it shuts down.

I’ve already tried SMC reset, PRAM/NVRAM reset, and fully reinstalling macOS; none of these helped. Any further ideas for how I could fix it?

Overheating mark on the screen in – any DYI ways to have it go away?

A family member of mine has a Redmi Note 5 since last September and has been a very happy user when one day, with no warning beforehand, a semi-circular, ring spot appeared on the right hand side of the screen, it looks like THIS now. It’s not like it was getting worse for some time, it was just – one day it’s OK, the next day, this appears. The phone hasn’t been dropped, kept near any warm spot or constricted in any way, it has its separate pocket in the purse (and spends 95% of the day flat on the table anyways). Since appearing around 3 months ago, it became significantly longer vertically, like twice, as shown in the photo.

After googling, this seems like it may be a low-quality glue issue after extensive heating of the device in normal usage. I’ve tried having this fixed under warranty but the store basically told me to go freak myself and I can’t do much with that (well, there’s warranty laws in my country for you) apart from going to court or paying for the repair from my pocket. Thus, I decided to first explore if there’s anything I may try at home before doing either. Anybody had success with fixing this on their own somehow? I know the chances are slim but still, it’d be nice if I didn’t have to shill out half the price of the phone to fix it now 🙁

Motherboard sounding false alarms on overheating DIMM socket every few minutes

I’m putting an older Supermicro X9DRG-QF motherboard back into service as a VM host. The machine did a great and error-free tour of duty in a digital installation a while back, so I can confirm it was working fine in a previous life. I have upgraded the RAM to 128GB with 8x16GB DDR3-1866MHz PC3-14900 ECC ram, and I had installed FreeNAS 11.2 for testing purposes. Worked like a champ, no issues.

I’ve recently been kicking the tires on VMware ESXi, and for some reason with that change the motherboard is now reporting that one (and only one) DIMM slot is going into UNR territory (127 degrees C from watching the real-time reports under IPMI dashboard), but from direct observation (touch) I can confirm that the DIMM temp is not actually spiking out of range (not even remotely).

I have tried swapping the DIMMs between slots so I can confirm it’s not a specific DIMM. Does this reek of a failing motherboard? Any advice on how to potentially isolate the issue would be greatly appreciated.

Overheating in Kubuntu 18.04 – Lenovo Ideapad 330-15ICH

I installed Kubuntu 18.04 in a new laptop (Lenovo Ideapad 330). I installed Kubuntu (along with the default Windows 10 installation) because, after a lot of tries with Ubuntu 18.04, it was not installing correctly and giving some problems.

Kubuntu works perfectly fine. Except for the fact that I have noticed that, while the computer’s temperature seems normal in Windows 10 (while playing some Gamecube videogames on Dolphin emulator, which I suspect does not overheat the GPU), when running Linux it gets abnormally hot, not enough to auto-shutdown because of the heat, but enough to notice a clear difference between Windows and Linux. And this just by browsing things on the internet, or even editing some texts in gedit. I mean, this overheating is not normal at all (software related 99%)

I took a look on forums and so on, and read that installing dedicated drivers (NVIDIA ones) instead of the default ones that come with the Kubuntu distro might be a solution for this, so I downloaded the drivers (the card is an NVIDIA GEFORCE GTX 1050) from here (https://www.geforce.com/drivers/results/145271). However, when trying to install the drivers, I got an error message discussed here (How to unload kernel module ‘nvidia-drm’?). I followed the steps there, but to no avail, because in the end I messed up with my graphical mode. I googled like all the afternoon and part of the night, tried other few things, but nothing worked. Finally I decided to reinstall Kubuntu again. Now, after reinstalling, I’m facing the same problem. Everything works fine, but overheating for no reason.

Do you have any ideas on why? And how can I solve this issue? I would appreciate any help because, although I can use the laptop like this, I know that this will greatly shorten my laptop’s life, and I think that it is something that should be fixed.
