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.
