Hello,

Everything is in the title: I have the well-known black screen issue on my C670, I read that a BIOS update fixes this problem, but it is nowhere to be found. The dynabook website, which is referenced, doesn’t recognize the C670.
Has anyone managed to find the file?
Thank you in advance.

Thank you Redbart, that’s exactly where I found a BIOS that refuses to install (TKBSC ROM instead of TKBSR).
So I finally gave up this search, especially since the method of disconnecting, removing the battery, and pressing the power button for 20 seconds while pressing the delete button at least 5 times ended up working!
I pressed for 30 seconds instead of 20, and since then it displays normally every time I restart.
Thanks to everyone who replied.

And that’s my problem! It is nowhere to be found, and yet it is indeed a C670-14M.
As for the search by serial number, it yields no results.

Hello,

If you go through family, series, model on https://fr.dynabook.com/support/businesslaptops/?productCategory=laptops, you can find your PC and a BIOS update from 2012.

Hello, and thank you for your response.

Unfortunately, the C670 is not listed in the BIOS...

I finally found this update (pretty well hidden!)
It clearly shows that it's for C670-14M, but the flash is refused because it's a TKBSC ROM when it needs to be a TKBSR model!!
If anyone has any idea.....

As GP pointed out, a BIOS update from 8 years ago is not going to revive your even older PC

I have the well-known black screen issue on my C670 and the solutions are not known?

There are indeed many other possible causes to check well before

Unless it is true that this new BIOS fixes a known bug.
Because solutions involving taking everything apart are very risky, require a very skilled hand and excellent eyesight: this is not a tower, here...
