Lenovo IdeaPad s340 burned motherboard ?

Re: Lenovo IdeaPad s340 burned motherboard ?

all cores have literallly same temp because it is on same chip. its just bad reading. that capacitors must not be there but u can have some instability so better add capacitors with same size.

If i remeber correctly, the notebook temperature was around 40/45 degrees Celsius before...
now it's highter everywhere and i don't like it very much because this temperature is basically in standby, without doing anything
Obviously as soon as I find a capacitor of the same size i will add it!

did u replace thermal paste?

45c will be only in idle

The temperature i wrote are basically in idle,that's why i say that they are a bit too high.
I haven't removed the black heatsink, so i don't relace the thermal paste.

Hi which processor do you have? If you got AMDprocessor you must use AMD overdrive. I have a lenovo G505s laptop when i use speccy or cpuz for temp momitoring the gives abouth 100 degrees C and when i use AMD overdrive utillity he gives 38 degrees. The other monitor apps doesnt give correct values.

Hi guys, I finally got it the capacitors and replace the old broken one.
The pc turn on like usual and the only strange temperature is the core 2 that is higher than the others (Image Temp 1: 80degrees Celsius vs 50/60 of the other core).
In images "Temp 2" and "Temp 3" there are the other temperatures that seem normal..
There is a big problem: the two speakers are dead.
I measured the resistance of both speakers and it's 4 ohms, so they don't look burnt out ... so what can I check now?

PS: windows can't see the speakers at all...

Here the image of the temperature:

Re: Lenovo IdeaPad s340 burned motherboard ?

temps are ok. dont bother with it.

for speaker?
find in schem if u have amplifier ic or just sound ic and check input outputs with headphone attached to probes

Thanks for your reply.
I haven't seen the schematic for the speaker in these days because I am not feeling very well.
In a few days I will get back to work and i'll ask for your halp again
