About Bios Update.

I have gt72vr.Sometimes electricity is cut off when I live. so I am afraid of doing bios update on laptop. Can I just update my bios when the battery is full with the laptop? Thanks.

 

It's ALWAYS advised to do Bios updates on a full battery in case. You shouldn't be worried tho, the system will do the update in around 15 seconds. I doubt you'll manage to lose power in that time. Also if u should lose the power, battery will come to the rescure

 

BIOS updates are disabled when running on battery on AMI Aptio BIOSes.
@cuneyt1984 Use a UPS or an inverter, just takes a minute or two to flash everything.

 

@Vasudev Yeah but I assume that means BIOS update won't start if the computer is running on battery but will continue if the AC power dies down during the update, or is it not the case?

 

Is there anyone who is experienced for this?

 

It might soft brick the laptop sometimes based on how MSI have configured their firmware. Best option is to ask @Falkentyne is there's an option to flash BIOS.
Even I have frequent power cuts and I turn on inverter.

 

Uhm, I'm talking about the situation when he loses the power in the middle of the update. It can't just stop and say "nope", that'd be disastrous.

 

On the computer Did you perform bios update only when the battery is plugged in?

 

No, I doubt people would do that. Also the update takes like 15 seconds. It's VERY unlikely you lose power in that short amount of time. If it happens it should still update via your battery. As far as I know the BIOS won't let you start a BIOS update while on battery, but once you started and lose power it will still run on battery.

 

In the MSI BIOS update document, there is no indication that the laptop, especially after the power failure, will be damaged. But they can inform me if they are experienced in this matter.

 

Again, you can start the BIOS update and if it should lose power while doing the update then it will proceed further on battery.
It won't cancel or break anything, also it won't allow you to start an update without power.

If you lose power while doing an update and not having a battery to keep it alive, then you will brick your mainboard. So charge battery to 100% and do a BIOS update on power.

 

Thanks friends. But they can inform me if they are experienced in this matter.

 

I asked this question to the technical department of the msi.

 

I don't know what will happen if the AC power goes out during a bios flash, sorry.
Most likely it will complete it, assuming the MSI engineers are semi competent. But I don't think anyone here is going to test that for you.

Why don't you just buy a SPI programmer and a Pomona 5250 clip and some male to female jumper wires to connect the clip to the flasher? (that way you won't need an SOIC8 adapter). Then you just force flash the Bios manually if something goes wrong. Yes this WILL require repasting the GPU with thermal compound (the Bios chip, at least in the GT73VR, is under the video card MXM module), but then you never have to worry about that stuff again.

Hello Cüneyt,
You can update your BIOS to E1785IMS.118 from the following page.
https://www.msi.com/Laptop/support/GT72VR-6RE-Dominator-Pro#down-bios
How to update BIOS: https://www.msi.com/files/pdf/How_to_update_bios_en.pdf
Please read the updating guide carefully, and update the BIOS in a right method.
Note : Power on your notebook with AC adapter.Please make sure that your notebook is running with AC power during entire update process.
Thank you and have a good day.



Best Regards,
MSI Notebook Technical Application Department

 

You will need to have AC adapter connected in order to proceed with BIOS update, but once the process is started then it must finish. If the AC power breaks off then it will continue to flash using power from the battery, however if the battery has no power then the BIOS will fail and the system will become bricked.

 

Thanks. Is this knowledge you have an experience?

 

Better to pray to god before you do the BIOS flash. If you're in warranty then go ahead. Otherwise find some place or day when your electricity won't be cut-off suddenly. You can ask your friends if somebody has a inverter or generator or standard UPS for backup power for just a minute or two.

 

YES THATS HOW IT WORKS.
