Event ID -37 of the kernel-processor-power

[SKShah]

Hello,

I get a warning (Event ID -37 of the kernel-processor-power) almost every time when I boot my laptop.First of all, here are the specs of my laptop:

The laptop is an Hp, bought brand new from Authorizes dealer during August-2014.

Therefore, it is still under warranty.

Every software on it is legal.

SPEC. is as under:

Make                    :Hp15 – r014tx Notebook PC

Operating System   :Windows 8.1 64

Processor                 :Intel® Core™ i5-4210U with Intel HD Graphics 4400 (1.7 GHz, 3 MB cache, 2 cores)

RAM                           :4 GB DDR3

Graphic Card           :NVIDIA GeForce GT 820M; 2GB Discrete Graphics

Display                       :15.6"

Hard Disk                  :1 TB

Before asking for help here, I did the following:

• Checked for RAM related issues ;
• Checked for HDD related issues ;
• Checked and updated every driver ;
• Updated the chipset/BIOS (as recommended by HP customer support) ;
• Verified the CPU and laptop temperatures (always below 50 celcius) ;
• Verified that the vents were not obstructed by dust ;
• Reinstalled windows 8.1 OS
• Checked the power settings.

The problem remains almost every time I boot my computer, I get a warning (event 37 in the events log) on my entire CPUs core: "The speed of processor [x] in group [x] is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report."

In the Event viewer I have 4 errors after each Windows boot

I would like to know what to do about it. Technically, it's just a warning, but it's kind of wearied. And since my computer randomly (yeah, without warning and with no obvious correlation with my usage of it) crashed a dozens of times already.

Also, I get same warning after reinstalling windows 8.1 OS.

I have a suspicion that this is simply Intel SpeedStep technology in action. In other words, for most computing, the CPU lowers its speed to save power, but can bump itself up to maximum speed if necessary. I read that there is BIOS setting for power consumption (which is to be disable), but looks like there is no such setting in my Hp15 r014tx notebook.

Hello,

After your recommendation, I have contacted Hp customer care and they replaced my system board (MB).

But this error is still coming.

Please refer my Hp Case Details:

Case status: Completed

Hp service engineer, install trail version of windows 8.1 Operating system in spare HDD and connect to my laptop for error checking and they observed the same warning log on spare HDD.

After that, he informed me that this error is not impacting on working of laptop.

Is it correct? If he is right than why this warning is still coming?

Please advice me, so that I can trust on HP.
