I had Android studio open, running its android phone emulator, when my laptop started making this sound.

 

I initially thought this may have been a malware issue, but Nasdaq informes it's probably hardware instead, see this post.

 

  • Windows 7 home premium 64 bit
  • Sony Vaio VPCEC4SOE Laptop, with an I5 processor and  6GB RAM
  • BIOS version is: American Megatrends R1140y8, 6/10/2010

 

I seem to remember having to enable hardware acceleration when setting up android studio, which suggests it's a hardware intensive process.

 

I've been digging around, and I found a post that said a siren type sound is CPU overheating.

 

1) can error sounds from the BIOS happen long after boot? (I can't seem to find this out on the net)

2) if it is the processor overheating, could I confirm with some logfile?

3) is there a way to confirm what this noise is?

 

Kind Regards,

 

Reggie.

Download HWmonitor to get the CPU temperature reading :-

Hi WebWalker67,

 

The CPU temperature is max 88 since i've run it. What should its max be?

 

I take it i should run this when the sound happens? 

 

Kind regards,

 

Reggie.

NEVER EVER LET YOUR CPU ABOVE 100 DEEGREES unless you want to replace a fried CPU

For safety lets try getting that temp bellow  80 Deegres, buy a laptop base with a fan to see if that lowers temp, if it continues doing that sound below 80 degrees then its not overheating issue 


Don't even think about it if your not sure

As bc said, 88 is hot for a laptop. I recommend taking the bottom of, removing the cooler, replacing the thermal paste and reassembling. Otherwise, contact a qualified technician.

1) what's the best thermal paste, and where to get it?

2) what's best application method: pea /grain of rice/ spread?

Artic silver paste is good and cheap.

2. All should work equally if the cooler is properly reinstalled.

I re-applied MX-4 thermal compound to my CPU and MPU, and now my max core on my i5 processor has been 66 deg C that's nearly 20 deg cooler running Android studio!

 

My fan isn't always on now as the average is now about 45 - 50 deg C!

 

Thanks everyone that helped,

 

Kind regards,

 

Reggie.
