EC Error (HP Spectre 13 Convertible)


Recommended Posts

I have an HP Spectre 13 Convertible laptop and I was trying to figure out why tablet mode would start acting weird (auto-rotate would stop working, the keyboard would suddenly come back to life with it on my lap and start typing gibberish)

Pretty sure I narrowed it down to AIDA64.

I see some of these in the Windows event logs:

: The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly.

I also see a lot of these, which I believe is the real issue, which is probably the side effect mentioned in the above log:

Check the remaining resource budget. Module exceeds resource budget, failed to AllocateFwCps, STATUS = Insufficient system resources exist to complete the API..

That is from Intel-SST-OED (some audio/mic thing).

Disable AIDA64, reboot, and none of those show up. How can I help you fix?

The laptop is using the latest BIOS, and the AIDA64 version is 6.32.5600.0.

We've recently revamped the EC register access part of AIDA64, so please upgrade to the latest beta version of AIDA64 Extreme available at:

https://www.aida64.com/downloads/latesta64xebeta

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

Let me know how it works.

It appears to have made the issue worse.

First, I see these events now in addition to the one I mentioned above (this one is a warning instead of an error):

: The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS.

Second, the error may have caused my system to hibernate due to a thermal event? A Kernel-Power error log shows up a few minutes after an EC error log.

In that case it's best to completely disable EC support in AIDA64 / main menu / File / Preferences / Stability.  I don't think you'd lose any sensor readings by that.

I lose fan speed readings, which I do want to see.:(
