Macbook Pro mid-2014 strange issues

ttouch · 2015-05-19 00:44:01

Hello,

I have a mbp 11,1 (mid-2014) and I have to kinda strange problem.
First, while the CPU is idle (90% idle powertop says) the heat is ~50-60C, which is weird. Normally, that would be 30-35C (when I had gentoo).
Also the battery does not last that much, but I think that's due to the heat problem.

Secondly, I have dwmstatus which reports battery percentage. It just reads /sys/class/power_suuply/BAT0/capacity but at the second suspend-resume cycle, the process falls at "D" state (can't be killed and I can't cat the capacity manually either) and fails to suspend/poweroff/reboot/resume (if it was suspended for third time).

The main problem is that I don't know where/what to look. dmesg according to my opinion does not show anything interesting.

Thank you.

also check error messages with

less | journalctl -b

Nothing interesting...

it would be very interesting to know if you use the discret GC or the intel?
Or do you use booth?
On a MBP it would be the best to run only the intel because of heat problems.
If you play games or use intense 3d apps and you need the discrete GC ...... the heat problem will stay.

I didn't found a way to use my AMD / ATI GC without a heat problem.

If you want to try to disable it take a look here:

I have only intel GC. There's no discrete in this model

Ok i see....bad first shot

here you go a complete tut for your MBP including "Post-installation" settings for more powersaving!

i have "stolen" some nice configuration tricks from that guy for my old MBP early 2011......and it works!

Hope that will help you!

ok a wild guess......
Bluetooth - isight - and Wlan is on?
If you dont use it shut it down!

if dmesg couldn't give you a hint ..... and the log dosn't give a failure .....
This is somethings for the "Pro" users here

Bluetooth disabled.
I don't have iSight, i have Facetime HD and there's no linux support (yet).
It's PCI Express.
Wlan is (almost) always in use.
But when I had OS X and used just wifi (no bt or facetime) the temp was around 35-40 C.
I've searched each and every corner of the web
The only left is TOR

*casting arch gods* please help me...

PS: Thanks for your time, double checking all these is crucial, not just for me, but for future readers too.

ok, i think i found something out.
PowerTOP reports 30-60 events/s for od_dbs_timer.
This has to do something with the ondemand governor.
What can I do to reduce/disable it?

bump...

Wow, I found the problem (but not the solution...)
http://i60.tinypic.com/2hcqp94.jpg

It's acpi's problem, with acpi=off everything runs smooth.
Also I updated ACPI and now after 20-30s of boot, the whole machine just freezes, acpi=off fixes the problem (but disables half the laptop's functions...)

I googled the messages and I found nothing.

I also disabled any power handling process (cpupower, etc.)

Ugh, I feel stupid.
The problem was a udev rule I added that caused an infinite loop in acpi.
I don't know the exact udev rule (I disabled several) but now everything runs super smooth.
The temperatures are fine (~45 C), the battery life is good and no more hangs.
