Win10 on the wood nvidia 358.91 (from 2015.11.9) works without a frieze.
There is also a bios 44CN45WW on which loading is accelerated (it is easily flashed from under Win10 as well as 44CN43WW)

CPU selection for the B570e

1. Download the free CPU-Z program fromofficial siteand install.
2. Run the program and open the tabMainboard . In line Southbrige There should be information about the chipset.

In this case, I haveHM65 .
The characteristics of the processor should be to support this standard.

Processors in the rPGA package can be replaced at home. The processors in the fcBGA package are soldered on the laptop's motherboard, they can be replaced only if there is equipment for the BGA (ball grid array) soldering.

Updated to the latest build of Windows 10 before disconnecting the discrete graphics card in Windows and BIOS.
Now the laptop only works on an integrated video card, because the existing Nvidia drivers do not want to be installed.
Is there any chance that someone will zashamanit us this driver?

Put on 8ki, I did it, everything went wrong, the driver in the header)) ...
damn, friends where you used to be, I tormented this beech for a month until I finished what to do with nvidia

What does this BIOS give?
I collected this beech from 2 modifications for myself, bought the case from one and the motherboard from the other, and as a result I lost the WI-FI enable buttons))) And what was my surprise when after installing the Wi-FI drivers on my miracle, he did not find a single network)) had to bomb-disassemble and turn on the toggle switch ..
And for what the left flipper? What does it turn off-turn on? Something on the Screen does not display anything

And another question is whether this book will take out 16 gigs of RAM?

And esche question)) Which I have for a long time right in my head hanging ....
Is it possible to upgrade the webcam by installing either the lens itself with a more powerful matrix or the board can ... I wonder how the scarf fits)) .. I would like a better camera
In fact, the camera is connected via a USB interface which is soldered on the board, so any is possible, but what is the module on which the camera sits and whether it will be compatible, this is the question or question)))

Dimon2NT, logically, you can It weighs usb. The main dimensions of the camera itself to pick up what would sit well in the case and not interfere.

From memory here everything is well described.link

You can also read here in the manuallink

And lastly in this group a lot of information on our laptoplink

Well, there is painted at the level of the official site ..... where it is supposedly recommended ....
But we are maximalists and we want more) ... I occasionally take photos and videos on the road, I need more RAM ....
Now 2 * 4 is installed, I think to try my luck to deliver 2 * 8, I have a processor: -Intel Core i5-2410M (2.3 GHz)
according to the manual he has up to 16 gigs of support, the HM65 also does not preclude .. in general I will try)) accomplish the results (but another interesting moment, this b570e is a real constructor, you can unsolder another slot for the operative under the keyboard, and in fact Core i7 with support for 32 or more gb can be put under the keyboard for another 8 gb)) and so there is a lot of things unraveled)) karoch for upgrade most it :))

Dimon2NT, in principle, it is possible but there is one thing but what to do with the restriction in the BIOS and how to get around it. With i7, the cooler will need to be redone. I have a Core i3-2330M, there was a celeron b800.

In BIOS, there are no restrictions on RAM, it’s checked, I’ve shed and Z570 BIOS in my beech, the laptop started up adequately ... the whole B570 line is compatible))) the designer, his mother ...))
About the bark, I mean two buckets: 2640M (4M Cache, 3.50 GHz)
I’m not very far away from mine, but I think I’ll feel the difference in 1Ghz)), but it’s not very different in heat

But for Nvidia, these IBM should be punished ... they got it, they managed to defeat it partially, with the firmware from the Z570! The latest drivers get up as it should, but there is a power problem, when you restart the laptop goes to the black screen ...
If there are master wizards, someone would disassemble the BIOS from the Z570 and from our reptile, would be very grateful)) ...

Dimon2NT, that's fine I have not modified my own prots. Memory 4 gig, screw 500 gigs - I have enough for my eyes.

WinSSLioN, Please add a cap, laptop storage AOMEI OneKey Recovery Free Edition not the first year I use it. Program so to speak with one button.
Worth on Windows 7 x64 Maximum.
And from the home archive, the first bios that stood on my beech
Version bios: 44CN36WW
Model: Lenovo b570e
Model Name: 20143 .
As far as I remember, he does not have uefi. Now 43 stands.

I wanted to upgrade to 45, but this flash drive tells me: Can not open the Firmware Device File for what it is?)) Again the flash drive to be drunk to the prog :(

Dimon2NT,
Remove the white list in order to install another Wifi module. For example, you bought a module that supports speed 300mb and you want to install, but the laptop does not see it. This is due to the white list in the BIOS.

for example

What is it? There the same thing))) 43 BIOS in an EXE file, maybe there is a flasher built-in .... I would like to shed the 45th)) ...

There is a tricky file there: 44CN43WW.exe
it looks like a script or something else that automatically starts the firmware process ....
Pre-unpacked.
I caught this moment with unpacking in the TEMP folder ... pulled out the files, replaced the file with my firmware, and nifiga, again the same error with an incompatible file ...
I take the palm off files that the flasher sewed, I also do not like it)) ... some tricky script is walled up
_____________
In general, I spilled the BIOS through: Pflash)) booted from Hirens there was a good old Norton Commander and everything was super-duper ...
I would now like to ask about the previous speaker, regarding the accelerated download to: 44CN45WW
And what is the speed?)) ..
Well, in general, it has been updated and so far calmed down)) Closer to summer I will experiment with processor compatibility and operational ... now for now know = mani

Dimon2NT,
also not installed, maybe because I have 32

Who is not installed? Driver on Nvidia?

Yes sir. After updating to the latest version of Windows

Look, I tried to update from 8 to 10, the driver crashes ..
Here I am subscribed to Insider Preview, almost every month new versions of Windows 10 fall and then literally on Tuesday, a new version of Windows 10 fell, I downloaded it, updated it .... and again the Nvidia driver crashed, and you know, the driver from the header, it was perfectly installed :) .. well, it didn’t work through the installer, I slipped the INF file in the device manager and then rolled the software from above through the installer
