How to update the BIOS on an Asus M50Vn laptop

I’ve had lots of problems with my M50Vn lately, caused by my tries at upgrading the graphics drivers for the GeForce 9650M GT (see this post, which I’ll update soon, once I’m sure the BIOS update fixed it). To summarize, any NVIDIA graphics drivers version 186+ would cause massive flickers and freezes, and it turned out that a BIOS update could possibly fix this. So I decided to give it a try.

First I grabbed BIOS version 212 from here (mirror) (search for M50Vn, then choose any OS (the BIOS updates are OS-independent).
Then I went to the instruction page Using ASUS EZ Flash to Update BIOS. It may help you to find how to load EZ Flash, otherwise the other instructions aren’t that useful: they say you need to unzip the BIOS file to a floppy or an USB key… Great, the M50Vn has no floppy drive, and I don’t have a spare empty USB key. But actually, you can just unzip the BIOS file on your first partition, in the root folder. I unzipped it into C: (so, C:\M50VAS.212).
Then it’s simple:

  • INSERT THE (charged) BATTERY: in case of a power outage, you’ll be glad you did
  • Restart the PC
  • During the early boot, press F2 to enter the BIOS (yeah, on their guide they got the keys wrong, at least for the M50Vn)
  • Find EZ Flash (I already forgot where it is, but seeing how raw that BIOS is you’ll find it easily) and launch it
  • Find the BIOS update file, and use it to flash the BIOS
  • At the end of the process, you’ll get a success message and the PC will shutdown. Congratz, you’re done 🙂 Without a floppy, and without a USB stick

Bonus: if you don’t want to bother searching the slow Asus site, I mirrored BIOS 212 for Asus M50Vn on Megaupload.

Additional info: I was upgrading from BIOS 207.

    Sorry I don’t have this laptop anymore. Maybe if you find somewhere a button to toggle “advanced” settings you might want to enable that, but otherwise I really don’t remember. That EZ Flash things wasn’t too easy to find, but if you browse around systematically you should find it eventually.

    Hello, I just upgraded the bios to M50VAS212 and yet everything remains the same, with the same problems … Someone can help me? Thank you

      Unfortunately, upgrading the BIOS doesn’t fix every possible problem (probably only just a few, actually). Without more details, it’s hard to help. Any component and software/driver can cause issues…
