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 (*For the model which can't remove the battery, you need to use a strengthen paperclip to plug into the EC reset hole instead.)
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.
Greetings and thanks again Bas......
Although in my case, the same as with the other person who posted before me, it didn't make any difference.

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?
:confused2:

If you're not having any problems, then no.

I do not see the procedure for flashing, just what to do after flashing.  I am missing something?

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.

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.

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

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.

What is your point?  Did the EC Reset solve your problem, or did it not?
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.

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.

Very interesting, does this Embedded Controller is in every laptop, Intel based and AMD? Is this MSI only feature?
