@Lost_N_BIOS Windows 8.0 is better than 7, 8.1 & 10 as you can read here it can do the same using less cpu, processes & ram: https://blogs.msdn.microsoft.com/b8/2011...y-in-windows-8/

And also I always preferred WDDM 1.2 , 8.0 it's the fastest OS & GUI has no lags. W10 has a laggy GUI, I will wait for the 1903 (19h1) update, but I doubt it will give me the experience I can get on my x86 tablet using Windows 8.0, or 8.1

The main problem I have is with a usb mouse using an usb 3.0 to vga adapter, the mouse freezes or has stuttering sometimes when I close a tab on chrome in the monitor which uses the usb-to-vga adapter (I use dual monitor config one the vga out & the other is the usb to vga)

I tried disabling selective suspend on power plan and disabled "Allow the computer to turn off this device to save power" on Device Manager -> USB Device -> Properties -> Power Management

I also have:
- Control Flow Guard disabled
- Action center disabled
- Core Parking disabled
- StartIsBack
- BlackViper service tweaks applied
- Simple System Tweaker tweaks applied..
- Some Ultimate Windows Tweaker tweaks
- Ultra Performance Power Plan

Doing this I can get less mouse lag on the monitor connected to the usb-to-vga adapter but it is also remarkable compared to 8.0 or 8.1

The mentioned lag disappear on my usb monitor when I connected it to a computer using Windows 8.0 or 8.1 and I can't notice system GUI lag at all compared to w10.

I also have pick "automatic color for taskbar.." turned off because of the GetPixel function bug on Windows 10. You know.. ;)

In my opinion it's all about WDDM & DWM.exe, w10 is a great OS but I prefer the 90s Windows responsiveness without lags

So, right now, I only have a few tweaks left to apply:
1) HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration
2) Try to enable Aero Lite
3) Enable old AltTab (https://www.askvg.com/how-to-get-windows...ws-vista-and-7/)
4) Classic theme with ReactOS taskbar http://winclassic.boards.net/thread/177/...-classic?page=8 or this alternative method to disable DWM in Windows 10 (http://winclassic.boards.net/thread/159/...=1&scrollTo=529)
5) Graphic card optimization registry tweaks as I read here:

I tested 8.0 and 8.1 for long time, and then 10 (Worst), to me 8.0 and 8.1 = same/same, but yes it's all up to you what you use

What? USB mouse to USB to VGA adapter, no wonder it's giving you issues, that's the strangest thing I've heard all year

Does it work if you don't have all these things done?
- Control Flow Guard disabled
- Action center disabled
- Core Parking disabled
- StartIsBack
- BlackViper service tweaks applied
- Simple System Tweaker tweaks applied..
- Some Ultimate Windows Tweaker tweaks
- Ultra Performance Power Plan

No, I don't know about pixel bug on Win10, I hate Win10 so have never used it at any length to run into any bugs nor ever read about them since I don't use it.
But, since you're using Win8, why are you mentioning and using this tweak, since it's a Win10 issue?

Win7 x64 = perfect for me, I've tried them all, and this is it for my needs. If Vista ran better and wasn't such memory/resource hog I'd probably use that instead

Back to the main issue, I still suggest you install latest BIOS, this could easily be a older BIOS bug and you'll never know and keep trying to solve forever without resolution if you do not try latest BIOS to confirm it's not a old BIOS bug.
There is no Win8 only or Win10 only BIOS, in that regard both = same/same

@Fernando - Thank you for pointing that out. I use the "Latest Posts" link only as my homepage for the forum, and answer/read all unread topics as I can get to them, so even if messed-up tag or something like that I will see the posts anyway once time permits.
This is the only way I look at the forum, so I don't even see the different sections unless I go out to main page to get a link from certain section

@Lost_N_BIOS I mean when the cursor is in the monitor which uses the usb 3.0 to vga adapter by startech, I have stuttering and lag when, for example, I close some tabs on chrome. This is happening in windows 10 on the new laptop and this is the reason I want to put windows 8.1 on it because I don't have this problem on another computer with windows 8.0 or 8.1

As you can see lot of people are looking to install w7 or w8 on this laptop:

https://www.google.com/search?q=330-15ig...rums.lenovo.com

https://superuser.com/questions/1381791/...-bsod-or-freeze
https://forums.lenovo.com/t5/Lenovo-Idea...GM/td-p/4289686

In other models you can change some settings in the BIOS to correctly boot w7 / w8 and install all drivers

Well, thank for your support guys. I thought that in this forum you could analyze the .sys file of the driver and search for strings that refer to windows 10 and update them.

I will some tests with UPGDSED ( https://github.com/hfiref0x/UPGDSED ) considering I have Secure Boot disabled to see if I can load the driver, and if not I will ask another forum.

Regards

Maybe it will happen on Win8 too, on this laptop, you never know, it could be BIOS or driver issue. If driver, then yes, Win8 and all the same stuff you are using on other system may fix it, if it's same exact chipset/CPU/BIOS.

What settings do you need added to your BIOS, I can probably unlock it for you if you want. If not, I can change the default applied settings. I assume, disable secure boot, what else?
Do you have programmer? If not, I can help you dump BIOS with FPT or faster will be this for now >> use Universal BIOS Backup Toolkit This may setup fasle positives, ignore or disable before downloading, window will freeze after you hit read, once it's done hit backup and send me the file
I don't particularly need this, but I do want to check something vs the stock provided image so would be great if you could back it up and send me a copy thanks.

I downloaded Universal BIOS Backup ToolKit 2.0 but when I opened it shows: "Can not identify the BIOS !"

Is there any other BIOS backup utility?

Hi @Lost_N_BIOS I tried to boot w8.0 x64 and I get ACPI BIOS ERROR bsod when Windows Installation is loading, some users with different laptop model changed an option in BIOS but I haven't this option in my bios ( https://forums.lenovo.com/t5/Lenovo-B-an...-7/td-p/3579435 ) , is there any other application to dump the BIOS ?

Thanks

@voug - yes, the stock package flash tool can backup the current BIOS via command line or GUI
CMD Line (run as admin) >> H2OFFT-W.exe backup.bin /g

To do via GUI, here is extracted package with modified platform.ini. This will backup BIOS and reflash BIOS too, so be ready (Or remove bios_rel.fd from folder, this may cause backup to fail too, unsure?)
http://s000.tinyupload.com/index.php?fil...919663825374710

If this system has ME Firmware we can also do it via FPT, check with HWINFO in the large window, expand motherboard, do you see ME area? If yes, what is ME FW version?

Before I read this I updated the BIOS today to a version released yesterday: 7XCN30WW

well, it uses the same H2OFFT-W software but with the name 7XCN30WW.exe

Ok, at this point and after I updated the BIOS I checked again but the graphics card isn't detected as I expected.

So now I tried renaming 7XCN30WW to H2OFFT-W.exe and execute the command H2OFFT-W.exe backup.bin /g

it show Extracting and a percentage but nothing happens and the file backup.bin is not created, I tried with an absolute path too.

About the HWINFO utility, YES, I have ME area and also I read about fpt (fptw? right?) I read it here:

https://forums.mydigitallife.net/threads...e-h2offt.71715/

So I will try to do the backup with fpt if it is what you're saying..

Edit:

Or... are you talking about Flash Programming Tool ? https://overclocking.guide/download/flas...ol/?wpdmdl=2742 ??

The changes in the new BIOS are:
General Information:

7XCN30WW:
BIOS Notification:

1. Fixed
1) N/A.

2. Add
1) N/A

3. Modified
1) SPI Lock Enable


If flash BIOS to 7XCN30WW, please don't flash back to 7XCN24WW or older version BIOS,or it will cause unit can’t power on.


Readme file here: https://download.lenovo.com/consumer/mobiles/7xcn30ww.txt

Edit2:

I downloaded Flash Programming Tool from here: Intel Management Engine: Drivers, Firmware & System Tools


And when I type: fptw64.exe -d output.bin -BIOS

I get: Error 63: Unknown or unsupported hardware platform.

So what version of C2. Intel (CS)ME System Tools I need ? I have Intel ME Version 4.0 Buid 1288 in HWINFO

Edit3:

I downloaded "Intel ME System Tools v4 r1 - (2016-10-13) For ICH9M systems which run ME v4" and I get:

PMXUtil: Error during PMX Call: sseidrvdll32e.dll!IDRVInstallDriver(): Failed to start loaded service err: 1275
Error 51: Initialization of PMX utilities failed. Unable to continue.
FPT.exe exited with return code: 51

I think this is not the version I need.. because it doesn't have fptw64.exe only fptw.exe

Edit4:

I'm gonna try this https://forums.lenovo.com/t5/Welcome-FAQ...one/ta-p/261119

I think what I'm looking for is to unlock the BIOS to see all hidden options like in this video: https://www.youtube.com/watch?v=lYhFqDBdlDQ

Edit5: Ok!!! I have the backup.bin with the comment you posted (first I extracted the .exe of the last BIOS) I'm gonna upload it and post it here the file in few minutes

I also tried this: https://www.youtube.com/watch?v=9y7kCZS7Jjo and restarted to see if I can access advanced options but I get a black screen when I entered the BIOS with some pixels distributed randomly on the screen.. strange

@Lost_N_BIOS Et voila the backup.bin of my bios:

https://www.mediafire.com/file/d9jbkn2ju...backup.bin/file

Please tell me if you need the backup using fptw too

As I have seen here: http://www.hpsoftwareuniverse2009.com/software/16.cfm it is possible to see all EFI global variables in a Variables dump.txt file using this tool

Once I have the Advanced Tab visible it seems I will be able to acces to these options or something similar to this: https://www.youtube.com/watch?v=plTKNA3AH8k

But please @Lost_N_BIOS , Consider what's modified in the latest BIOS update (because I don't want to damage the laptop): "3. Modified 1) SPI Lock Enable"

Edit:

What about EzH2O ( https://forums.lenovo.com/t5/Welcome-FAQ...EFI/ta-p/279868 ) to directly edit the .df file ?

http://www.mediafire.com/file/0zg6966v21hkw36/EzH2O.zip

I also found this InsydeH2O BIOS Modding Problems

well, I hope you know how to take a look at the hidden options in an HEX Editor or something similar.

Lot of thanks

@voug - For FPT, show me what ME FW version you have (Show image of HWINFO64), you need to get matching ME System Tools package. FPTw / FPTw64 does not matter, I suggest only using FPTw anyway and never x64 version
Yes, I would like FPT dump, especially since it may be easier to flash back mod BIOS that way. What did you use to create the dump linked above? I don't need anything extracted from exe's

Once you create FPT BIOS region backup via >>> FPTw.exe -bios -d biosreg.bin
Then please immediately try to flash that dump back and show me image of any error that happens (If any) >> FPTw.exe -bios -f biosreg.bin

That BIOS change log is useless info, to you, and to me they change 100's of things in BIOS every time there is an update, and then tell end user 1, 2, maybe 3 things they changed and even on 2 of those gave no info, so useless as you can see.

Yes, there are many tools and methods to edit a BIOS, depending on what you're doing and what does/doesn't work with the BIOS.
You still have not answered my questions on post #20 about the BIOS settings you need/want etc.

@Lost_N_BIOS I want Avanced tab unhidden to play with ACPI things and also Whitelist removal



All I want is the graphics card detected on windows 8.1 or the ability to boot w8.0

The touchpad won't work too on w8.1 but I don't have any Display adapter detected

Edit:



As I can see, on W8.1 HWINFO detects the graphics card, but is not listed on Device manager or devmanview because I tried to find the hardware ID on devmanview

@voug - Thanks, you need this TXE ME System Tools package (Intel CSTXE System Tools v4 r3) to use FPT From >> Intel Trusted Execution Engine: Drivers, Firmware & System Tools

On the graphics, so you booted to Win8.1 now, and the card is shown in HWINFO64 above, but not device manager, correct? Did you install chipset and Intel Graphics drivers yet? It may not show up until you install the graphics driver.
What do you see in this situation with GPU-z, and at the bottom of the main GPU-z window, see the drop out tab, if you can select more than one graphics device there show me image with both selected. - https://www.techpowerup.com/gpuz/
Also, show me image of CPU-z graphics tab https://www.cpuid.com/softwares/cpu-z.html

@Lost_N_BIOS

Screenshots:
" FTPW64.exe -bios -d biosreg.bin " result:



FILE biosreg.bin: http://www.mediafire.com/file/usb8lspzi5...iosreg.bin/file

I didn't flashed back the biosreg.bin because I'm not sure if this can brick my laptop so first I will need to be sure that I can restore back the bios with an USB and DOS I think (not sure) tell me if I'm wrong, thanks

GPUz


CPUz


As you can see the GPU is not detected in this applications (as in Device Manager, so in Windows in general except for HWINFO and AIDA64) but Chipset drivers are installed (with driver signing turned off)
