Y700 - Embedded controller problem

Does anyone else has the next error in the Event viewer :

 

Source ACPI , Event ID 13

The embedded controller (EC) did not respond within the specified timeout period.

This error occur when the battery is lower than 70%, 60%  (the battery voltage and status is totally random, but its not on the high level) and i plug in the charger, after 2 - 5 minutes the keyboard stops responding and basically everything related to the embedded controller stops responding.

 

This happen in BIOS mode too, the keyboard suddenly not responding (again related to the embedded controller).

 

I have to hold the power button for a few seconds, in order to shut down the computer. When i want to turn it back on, i have to press the power button many times (push it down and hold) otherwise nothing happens. 

The only way the computer will not repeat this symptom, is to charge the battery while the computer is off, then the battery charges to 100% and it is usable again.

Re: Y700 - Embedded controller problem

This can be cause by incorrect BIOS settings, outdated drivers/firmware and even mismatched or loose RAM.. 

 

I would try updateing the following drivers/firmware

 

From http://support.lenovo.com/us/en/products/laptops-and-netbooks/ideapad-y-series-laptops/y700-15isk?

 

  • Update to Latest BIOS from Lenovo   (version: CDCN35WW   dated 4/6/2016)
  • Advanced Configuration and Power Management Interface (ACPI) Drive  (vesion: 1.5.0.14-20150824   dated: 2/3/2016)
  • Latest Intel Chipset Drivers and Management Engine drives.  (version: 11.0.0.1168    dated: 10/22/2015)
  • Reset BIOS settings to defaults

Good Luck

Re: Y700 - Embedded controller problem

Before posting my initial post, i checked the ram (switched the places of the ram), reseted the bios to it's original settings and also updated all the drivers to their latest version. 

so now all the drivers are updated.

 

The only thing i did just now is updating the BIOS to CDCN35WW version, hope it would help.

I will keep you posted if it is the solution for the problem.

Re: Y700 - Embedded controller problem

Updated the bios to CDCN35WW version. After the update i discharged the battery to 11% and charged the battery to 100% without a problem (really thought the problem was solved) , then I discharged it again to 30% and right after i started charging it again , BOOM -> ACPI (EC) error.

any thoughts??

Re: Y700 - Embedded controller problem

You people really need to add a full detailed signature about your notebook(s). It depends...a lot of factors can be the basis for a proble.

- is the the factor installed image you're working with

- Which version of windows is it.

- how was it upgrade if so, via WU or clean install(the clean install will create a lot of problems and need time to patch)

 

Without anything else my guess barring a hardware issue is the Power Manager. Odds are the PCI Buss is being powered down to save power or being managed by the Power manager. I disable all management control for all ports etc in my systems. NIC, WiFi, PCI, PCI express  if there, USB, HD, everything. Otherwise sh...t happens and hair starts to fall out as you pull it.

 

I'd start there and if its not a current manager update it.

Re: Y700 - Embedded controller problem

As stated before this issue can occur in the BIOS/UEFI environment as well, the keyboard can become non - responsive and a hard reset (pressing for a long time on the power button) is required. My OS is windows 10 home 10.0.10240, Ideapad Y700 Touch-15ISK 16 GB ram 

I updated the bios with the windows installer executable from here

 

http://support.lenovo.com/il/en/products/laptops-and-netbooks/ideapad-y-series-laptops/y700-touch-15...

 

I also disabled all management control for all ports in my system. NIC, WiFi, PCI, PCI express, USB, HD, everything.

 

any other ideas?

Re: Y700 - Embedded controller problem

In my case, the keyboard freezing occurs with AC adapter on, which means 100% charging status.
