B590 - Is the latest BIOS OK for HM77?

Hello everyone! I have recently ungraded the motherboard of my B590 to HM77 so that I could use it with an Iintel core i5. My question is, is the latest BIOS for Lenovo B590 for both versions of these laptops? I mean, does it support HM77 chip? The current BIOS of the board is very old (2013) and Windows won't switch to Nvida GPU despite it's presense in the device mangager. Thanks and I really appreacite your support!

Re: B90 - Is the latest BIOS OK for HM77?

I'm not clear on whether you have a B90 or a B590.   It would be helpful to get the full model number (from where the serial number is), and a screenshot of a 'sys info'.   Thx.

Re: B90 - Is the latest BIOS OK for HM77?

thank you very much for you kind reply. Sorry about the typo, it's Lenovo B590, but I have replaced its mainboard. The origional mainboard didn't support Intel core i5, it had a board chip HM75 or something, the new board has HM77 chip, also on board Nvidia Gforece 610m. Before I post some sys info, the Laptop is running fine, but in Windows 10, the internal Intel graphics GPU is active, even though the Nvidia is recognised and seem to be ready to take over. I tried to disable the internal graphics chip, but after restart, the system run on unrecognised graphics engine. The current BIOS is very strange, it does not show any serial number and seem to be faulty, but I could be perfectly wrong.  I also tried to run the latest BIOS but it complanied and showed something like, your system is not supported. Thanks!

Re: B90 - Is the latest BIOS OK for HM77?

I see that you're running Windows 10.   On the support page for B590, it doesn't have Win 10 drivers (nor an update program for the BIOS for Win 10.)

Lenovo drivers are all included in Windows 10, my system has no driver problems. But thanks for your kind reply! Best wishes! Smiley Very Happy

Re: B90 - Is the latest BIOS OK for HM77?

Your system does not have Lenovo Windows 10 drivers.   I checked your B590 for Windows 10 support by Lenovo, it is not listed.  

 

Further it states explicitly that your processor is not supported (Intel 2nd generation Intel® Core™ processors (Sandy Bridge) -- as it is not supported by Intel and Microsoft for Windows 10.)  

 

Which could explain the issues you are seeing.  The suggested first step would be to run a supported Operating System.

Re: B90 - Is the latest BIOS OK for HM77?

hi again, my Windows 10 system has no driver problem, it works fine and Windows 10 runs quite smoothly with all the latest Lenovo drivers perfectly installed. My system has a BIOS problem, and I can't find any info on Lenovo B590 HM77 BIOS or any tools to backup or at least scan the BIOS for problems. The change that I wanted to make is, right now in Windows 10, I have two recognised graphics GPU, one is internal with the system's CPU, and one is an Nvidia seperately mounted on the mainbaord. Windows 10 don't let me to disable the interal GPU and use onyl Nvidia, because, I think, BIOS don't allow that. But I have come to a conclusion that Lenovo simply has no support, that's it. But thank you a bunch! Smiley Very Happy
