Lenovo B590 bios needed

Re: Lenovo B590 bios needed

I use CH431 and the chip is detached from the board.

I strongly advise you to use AsProgrammer_2.0.0a14, NeoProgrammer V2.2.0.8, or Colibri.

Why do you ask that? What problem do you have with your machine?

Re: Lenovo B590 bios needed

because before it turned on with difficulty sometimes you had to remove and reinsert the bios battery, now not even in this way

So what you are waiting for - try Peste's file, or the one at post #3 uploaded by Mcplslg123 it's confirmed working, and Peste's dump is virgin file extracted from Lenovo website, if the problem persist, obviously your issue is not bios related.
But before that check power button functionality. Is it working properly? 3.3 volts present on it? Does the voltage drop to zero when the button is pressed? Come ooooon these are basic things. Why haven't you checked them by now, instead of taking out the bios battery all the time, and relying on board auto-start functionality?

Re: Lenovo B590 bios needed

yes, I know, the 3.2 on the power button are there and go to 0v so I wanted to try with other bios

Lenovo B590 BIOS Help Requested

Hi, I could do with some assistance in finding the right BIOS for a Lenovo B590/LA58 11273-1.

The laptop in question corrupted its BIOS during a failed upgrade and, sadly, none of the original data seems to have survived.

I programmed an alternative BIOS that I found on here, which kind of worked - the laptop came back to life but the disc interface wasn't functioning. At this point I discovered that there were three different BIOSes for the same laptop, depending on the version, and I now had an H9 main BIOS but an H1 EC BIOS.

I assume that that means that I need an H1 main BIOS to go with the existing EC BIOS, but I can't find a copy of one of those. Lenovo publish a Zip file (h9et75ww.zip) and an executable (h9et84ww.exe - don't want to publish any unallowed links!) that both contain the three different versions, but I can't work out how to use what is in there to produce a programmable H1 file.

Even if the update fails, the bios is still there and cannot be lost until you arbitrarily write a strange bios into it.

You're welcome to have a look at what I saved, but since I couldn't open it in UEFITool I assumed that it was beyond hope...
