How to reset the EC (Embedded Controller)
« on: 20-November-07, 13:54:04 »

DO NOT FLASH YOUR NOTEBOOK UNLESS YOU REALLY HAVE TO!!!!
Lots of people already had to RMA their laptop because of a badflash or wrong flash.
Be warned, do NOT flash because you want to....only if you really NEED to flash to fix something.

If do you flash a notebook BIOS, you must do the following AFTER the flash:

1. Turn notebook OFF with button, hold 4 seconds.
2. Remove recharge plug
3. Remove battery
4. Leave it like this for about 5 minutes.
5. Put everything back and power the laptop again.

The new BIOS should work properly now.
This procedure resets the Embedded Controller (EC), so best been done as described.
(MSI Europe informed me about the need for this procedure)


If you have been directed to this thread because you have been asked to perform a EC reset,
note that we're not asking you to flash your BIOS, just perform the EC reset.

This didn't work for me.

DO NOT FLASH THE BIOS IF YOU DON'T HAVE TO.

Hello!
The intended battery here is the energy battery or the system clock battery?
Thanks in advance.

Your battery at the back of the lappie, the big block ;-))
Ergo, the energy-battery.

Cmos reset is NOT the same as EC reset!

The EC (Embedded-controller) is powered by the battery-block and will be reset if the big-block is removed.
The Cmos (Is BIOS data memory chip and Timeclock) is powered by the little lithium battery on the motherboard.

After a BIOS flash the EC must be reset to avoid wrong power reading amongst other things.

Well, I didn't do this resetting the EC thing when I flashed my Noteboook a few months back...

Should I still do it or has the boat sailed miles away now?

Yes, this thread is about resetting the EC after a BIOS flash. It does not concern the actual flashing of the BIOS.

Please, if you need help with something, start a new topic and ask there, these informative sticky topics are not for individual troubleshooting.

I asked about:

Q: What are the symptoms of a Embedded Controller (EC) that needs a reset? In other words what are the components, or operations that are being negatively affected?


Components or operations that indicate the EC needs to be reset:

The quoted sections are a attempt to start a listing of components, symptoms of problems that are affected by the EC controller.


After a BIOS flash the EC must be reset to avoid wrong power reading amongst other things.

I own the MSI Wind U123-002US Notebook.  I recently flashed the BIOS to the latest version found on the MSI Mobile Website dated 2009-11-02.  The filename is n033_10d.zip.  I used a USB bootable flash drive to start up DOS and ran the flash utility.  It completed successfully and I verified the new version of the BIOS.  I did this in preparation for an installation of Win7 on the 1st partition.  My other partition runs "another OS".

Long story short.....since the upgrade of the BIOS I have had very loud FAN noise when I 1st start the Notebook.  This never occurred with the prior version of the BIOS.  I have read that the FAN is supposed to come on during startup but believe me, this noise is very loud and I honesty never noticed any noise with the prior BIOS version.  This noise remains until after the BIOS post is complete and either of the two OS's boot.  Once the OS starts to boot, about 10 seconds later the noise goes away.

Any ideas?
Information from BIOS:

BIOS Version: EN033IMS Ver.10D
Build Date: 10/26/2009 16:26:39
EC Version: N033EMS1 Ver.112
Build Date: 10/26/2009

Thanks,
JR


Do ec reset: http://forum-en.msi.com/index.php?topic=112416.0

Hi everybody.
I was stupid to update my BIOS on my GX700 from 1719_1.19 to 1719_1.22 and now my monitor do not turn off as I selected in the power plan (after 10 min). I'm using Windows 7 and before updating the BIOS everything was OK. I reinstalled the same windows 7 with same drivers (fresh copy) to be sure but nothing changed. I read all in the forum about bios flashing and resetting and I thing the only one way is to flash back the old version (1719_1.19). The problem is that I forgot to backup the BIOS.
PLEASE HELP. I need this BIOS. My MAIL : email removed to protect user from spam . Thanks in advance.

If you are talking to me, I had asked what the symptoms were of a EC that needed a reset, and what components, or operations may be affected if the EC is not reset properly.

Well, there are a wide range of symptoms:

- no-boot/no P.O.S.T. situations
- loss of peripheral functions (no audio, no WLAN, no LAN, no USB Functionality, no webcam etc.)
- features accessible via the FN-Buttons do not function properly or not at all (volume, screen dimming, webcam, WLAN on/off etc.)
- problems with fan regulation (e.g. fan always running @100%)
- unexpected system behaviour

As the EC Reset is a very simply and non-intrusive procedure, it is probably not very useful to look at the symptoms and make list about them.  An EC Reset should simply be done after every BIOS Flash for prophylactic reasons to take care of potential misconfigurations regarding the EC.  This eliminates the problem at its potential cause.  All the symptoms above can be caused by other things as well and cannot be entirely related to the Embedded Controller alone.

Just asking, but does this thing happen if you use the laptop without battery, then turn it off normally through start menu and then remove the powercord from the walls plug?

What bad could this thing do then? (I shouldn't keep my battery removed from the laptop? Doesn't having it in the PC make it get bad later and doesn't having the laptop plugged in consume power too?)

Okay, good to know. I though the battery gets worse if you keep it on all the time.

By the way, if someone has done this reset accidentally, what might it do and how to fix it?

Okay... I was just wondering as I've almost always used the laptop without the battery in it and recently I've started also to take out the power plug from the wall, so it wouldn't consume any power. So I dind't know it could do anything harm to the laptop, but you mentioned about something that this thing could do and I also noticed that I had a sudden FPS drop while gaming and also my webcam hasn't been fully working after that, neither have I been able to go to BIOS settings through F3 etc. keys in the beginning menu... And I think this FPS and webcam thing started happening pretty near to the first time I removed the power plug aswell. Could this be just a coincidence, or could it have something to do with this?

Wanted to thank you for the simple method to reset EC. I have a VR420, running XP. Figured I would try splashtop beta un-supported platform. It booted to splashtop but took almost 2 minutes. Figured I would uninstall. additionally it did not detect the wireless lan card. So, I shut down and machine would not power back up. Lights would come on, but no display, not even on external VGA, no post screen options, nothing.

I cannot say for sure what splashtop did, if anything, but the reset of EC allowed me to boot to windows and uninstall it.

Thanks.

You say to wait 5-10 minutes with the battery and dc out... is this so the residual power in the caps drain or something?
Is there a way to speed this process up?  Like say, shorting pins on the battery socket's connector or similar???

From my own experience, you don't have to leave it out that long, but I'd leave it out for at least a minute before putting it back.

Nope, those are BIOS things they will kept powered by CMOS battery

It will reset EC RAM to defaults, like Wi-FI, BT, brightness levels, FANs and others to their defaults value.
So if you change any of them to custom one, at next EC reset they will be forgotten and auto disabled[which is their default state]

This will also fix "dead battery" problems where windows will show your battery to be broken, fx. after letting the battery die out while the laptop is in sleep mode. Follow the steps and the battery will possibly be fixed magically.

concerning this EC reset,

under the heading : - features accessible via the FN-Buttons do not function properly or not at all (volume, screen dimming, webcam, WLAN on/off etc.)

the problem i have isn't that the fn button doesnt work, what happens is when i use it it reset my keyboard typing speed.

i think this might be more a keyboard controler problem ?

Dear Svet

If do you flash a notebook BIOS, you must do the following AFTER the flash:

1. Turn notebook OFF with button, hold 4 seconds.
2. Remove recharge plug
3. Remove battery
4. Leave it like this for about 5 minutes.
5. Put everything back and power the laptop again.

The new BIOS should work properly now.
This procedure resets the Embedded Controller (EC), so best been done as described.
(MSI Europe informed me about the need for this procedure)

First of all, I would like to say hello to everybody, it's my first post here on MSI Forum.

It's good to know, because in the next week I am going to buy MSI GX70 3BE and update BIOS to the newest one. I've heard that there is a possibility to disable Enduro and integrated GPU, to boost CPU, but it's only possible with unlocked options in BIOS, is it correct?

EDIT

Svet I have sent you an e-mail message. I would be glad if you will reply.

Thank you in advance.

Best regards.

Sincerely
