High cpu temp without usage

klios · 2015-08-02 02:41:49

Hey guys, well Im having more than 40⁰C on my laptop (Idepad Flex 15) with anything open. Its between 40 and 45 celcius (104 to 113 F). Also I having normal battery consumpsion for a laptop with anything open (5W).

I tried thermald, laptop-mode-tools. I have Intel Graphics and a 4500U i7 Processor, wich I think has lower consumption and temperature. Im writing this with firefox now and it jump from 40 celcius approx to 45.

I have no CPU usage, between 1% and 5%. Some cores on 0%. I touch the laptop and its a little warm, nothing out of normal.

Sry for my english.
Thanks.

That may not be an issue at all. What is the critical temperature reported by acpi -V?

Critial temperature = 100 celcius. But it says 45 degrees, ok.

I dont know what that meant.

What it says. My laptop hovers around 40-42.

1) Check BIOS for settings value like Performance(Max performance) and Battery Life(Max Battery Life).
If you are using linux on laptop - don't set PERFORMANCE value. Only BATTERY LIFE.
It's working for me.

2) Don't use THERMALD package - if you have INTEL CPU Sandy BRidge or newer.(because of active P-STATE)

PS: Laptop - ACER V3 771G.

Why? If you don't mind me asking. I have it running on a broadwell i5 5257U and it's saved me a lot of battery and cooled my laptop down a little.

IT's worked not stable for me:
"With several running processes at the same time(firefox - youtube watching, vlc, virtualbox) laptop begins to slow down greatly"

Oh ok, so it's throttling the cpu too much. I'll keep that in mind if I ever fire up some VM's on my laptop. Thanks.
