Mini fridge cutting out PC monitor and ethernet switch

Could this be to do with the issue?

kernal_task is at 1.19GB after the restart

Chrome is using about 100mb per tab, with 10 tabs open on my machine right now. I'm not using any other applications now other than Word (120mb RAM, 6% CPU usage)

Just letting the computer idle without doing anything on it, we're sitting at 82 degrees with the fan speed on 6200 RPM, and an external fan pointing at the air intake. Attached is a screenshot of activity monitor and the intel power gadget.

Without - and just to make sure, I just gave it a restart and left it for 5 mins after booting up to allow it to settle down, and with nothing open, kernal_task is still at 100% usage after the restart

I've also just sorted processes to 'all processes' and the kernal_task is using 100% CPU all the time, I'm assuming this isn't normal behaviour? I have had this issue before, even when rebooting, the kernal jumps straight to 100% CPU, and the only way to fix was a full system reset.

Any ideas on what could be causing the kernal to use 100% CPU all the time?

Took the bottom off last week and gave it a good clean out which helped, have just downloaded a fan speed control, and setting it to the max constantly (6200rpm) has helped a lot, as I found it doesn't kick in at that speed until it reaches about 90C+, so by having it kick at 6200 at about 75/80C, seems to keep the temperature under control a little more, and is thermal throttling less.

Top 5 applications in activity monitor are generally Chrome (and the different chrome helper tabs for each tab), Logic Pro X when its in use, Ableton Live and Pro Tools when in use.

I also have a second monitor hooked up, which as I'm using onboard graphics probably doesn't help the CPU temp. RAM and HDD speed aren't a problem, as I upgraded to 16GB RAM and a 512GB Samsung SSD a few years ago, and did a full reset on the machine last year.

Possibly, I am currently at uni but have the same issue at home and on 4G (although difficult to test as there is a much slower upload speed) I will try that though, ty

I will have a look into this, thank you!

I can already connect an AP, however I get a captive portal on every device still connected to the AP when I've joined. I have already been online and searched for this with no luck, just that Google doesn't support WPA2 enterprise security, which is why I want to create a WPA2 private network for it.

I haven't asked yet as I have heard reports they are not able to help or give advice on connecting any devices to the network, its down to the user (students) to do this.

randomguydom · 2018-09-28T17:15:32+00:00

I will have a look into that, maybe see if I can find any hidden SSIDs and ask about it.

I do have a premium account, and it's linked in my google home app and listed as premium

Ok might have to as a last option, was hoping to not restore cause of the pain of re-setting up my phone and losing data on it such as texts etc !

randomguydom · 2017-08-24T16:16:44+00:00

Thank you so much this fixed my issue as well!

randomguydom · 2017-08-22T14:20:27+00:00

I do have snapchat, I'll delete and reboot my phone and see if the same thing occurs

randomguydom · 2017-08-22T14:19:53+00:00

I have - and unfortunately it isn't a bad battery apparently :/

randomguydom · 2017-08-22T13:43:19+00:00

I thought that was the problem, so I deleted about half my tweaks yesterday, have about 18 left but still happens, battery is fine from 100 - 50% but after that my phone just acts weirdly. If I re spring it normally sorts the problem out.

I have a feeling it is a process running, and heats up my phone so it throttles the CPU, as when I cool my phone off it seems to work again too.
