I opened up the notebook but couldn't find a battery of any kind to reset the BIOS. The Lenovo G770 model apparently lacks a dedicated BIOS battery; furthermore, I couldn't locate a reset jumper on the motherboard either. Consequently, while researching whether it might be possible to overwrite the existing BIOS firmware, I stumbled upon this website.

I noticed that some users here had attempted to initiate a boot sequence using the FN+B key combination. I decided to attempt a similar procedure myself, as follows: First, I downloaded the BIOS firmware for the G770 model directly from the Lenovo website. Although the file is packaged as an executable (.EXE), it unfortunately does not run directly. I extracted the contents of the compressed archive (using 7-Zip), which yielded a specific .BIN file (PIWG4310.BIN) along with several other files. I then copied this .BIN file onto a 2GB USB flash drive that I had previously formatted using the FAT32 file system.
1- Next, ensuring the computer was unplugged from the power source, I pressed and held down the FN+B keys.
2- While still holding down FN+B, I inserted the USB flash drive.
3- While still holding down FN+B, I plugged the power cord back into the computer.
4- While still holding down FN+B, I pressed the notebook's power button to turn it on.
5- With my fingers still pressing FN+B, the cooling fans began to spin; however, the screen remained black, and the system simply hung there. It seems unable to locate and load the necessary file. I waited for 10 minutes, but the screen remained black the entire time. I also tried using several different USB flash drives, but to no avail.

What should I do? I would be extremely grateful if anyone could offer some assistance.

Hello! New here and stumbling around hoping for a little assistance. Self induced dilemma = I decided to build a ridiculous game box using a lenovo Y570 model# CB01061723 which was headed for e-waste due to cracked screen etc. I pulled the mobo and had it connected via hdmi. Full disclosure.... This poor thing will never have a battery again and now has the full 16gb ram and I fully intend to use an external gpu. I came across a V2.06 unlocked bios and after many failed attempts due to efi boot partition size, got it flashed. All was well until I fiddled with display options and managed to black screen. I pulled the CMOS and spammed the power button and let sit for hours to no avail. Gave up on that, pulled the Efeon chip and flashed the original bios back (which I dumped from the start) using a t48 programmer. Still black screen 😑. Yes I've properly poo'd the bed. Yes, this is a stupid project. This thing is a dinosaur but had all the I/O that would be perfect for a retro box. Anyone have any suggestions? Thanks in advance.]]>

I am new to bios update but i got a old intel motherboard and a xeon E5 2680 V1. After some research i found out that this xeon processor is supported on the DX79 but after some bios update. 
After many attempts to update the bios from 537 to 590 ( i used the classic method press F7 then use a stick format Fat32. Then i used intel express bios update on win7 32bit) 
I read that the intel bios on those boards can be updated only with SPI programmer. I made a bios back up from the chip and then when i wanted to write the new bios i found out that the 590 bios have 9.9mb and the old bios have 8mb.

So now i need someone that can send me a 8mb 590 bios or tell me where i do wrong...]]>

Can anyone provide BIOS file I can actually use?

I have an Asus m513u ryzen 5 5500u laptop

For some reason the prochot flag is set and the cpu throttles to 400mhz when the battery is installed.
On AC with the battery removed the laptop runs fine. 

I have dumped the current bios, used uefitool to extract the PbsSetup and CbsSetup.
Used ifrextracter to convert to text.
I have used ru.efi to try and make changes.
I cant figure out what to change to disable prochot, or to get the laptop to run fine with battery.

This is the first time I am trying something like this.
Pls, any advice will be greatly apreciated]]>

• Model No: RZ09-0220 | Product Code: RZ09-02202E75-R3U1
• S/N: BY1747A13900750

BIOS chip:

• Macronix MX25L6406E M2I-12G (SOIC-8)
• 64Mbit / 8MB, SPI, 3.3V
• Date code: 58408900 K174583

Situation:
Board was hit by power transients during a tropical storm. System is completely dead — no POST, no display, no fan spin. Suspect corrupted/blown BIOS flash. All other hardware tests clean.

What I have:

• CH341A programmer
• Spare MX25L6406EZNI-12G chips (DigiKey)
• Plan to unsolder the original chip and read/compare before writing

What I need:
A clean dump from an identical or closely matching board (RZ09-0220, ideally RZ09-02202E75-R3U1). Razer support declined to provide firmware.

Happy to post my dump once I have the programmer in hand — could be useful for others with this board.

It seems that what i really need is a good method to change HWID so that Windows says it is not activated. I did try lately to change .rom with HxD and the afuwin-3.05.04 which it worked half way at least for a few boots. Problem i had is that somehow my Intel Ethernet adapter stopped working which isn't really an issue for me as this Motherboard has 2 BIOS chips and even if i brick one i still have the other.
I bought an original Windows key in hope that it will overwrite the one stored on MS servers but that doesn't work either whatever i do this Windows Enterprise key overwrites everything and executes some custom .ppkg files (i did try to change default app for ppkg files to notepad).
Is there anything i can do to fix this please i am soooooo tired of this issue all i want is to unlink my PC from the Enterprise key forever, i do not have any game bans that would be the least of my issue.
I am not a professional but i do understand a bunch of stuff and i am also very fammiliar with terminals so there is no problem. Also is there any way i could get to downgrade Intel MEI or overwrite it? My goal is to completely reset the mobo as it was when i got it, RAM training and everything from scratch.
I also attach a few screenshots so you can see what i'm talking about so even though i am using Pro the registry has Enterprise entries. Yes i already tried (me and a bunch of ms help agents) to change them and custom install again it always shows up as Enterprise as soon as i connect to the internet and Event Viewer spits out UserDeviceRegistration each boot. It's much more to say but these are a few good examples. Also the last MS agent told me that this happens because i have an Enterprise code embedded in my mobo (OEM) but i am sure i don't because when i open RW Everything and try to look for the ACPI > MSDM i cannot find it...

If you need me to upload anything please let me know, also if you want me to pay i have no problem with it.

I belive that the bios is corrupt. When powered on fans spin for a bit, keyboard remaigns lit up, but nothing else happens. I have tried to power it on with only the main board, a stick of RAM, heatsink and fans connected, and then do the caps lock test but it did not respond. If I connect a usb device it only charges. I have also tried removing both bios and main battery and let it like this for a while but it did not help. I also tried the acer crisis recovery, I formated my usb drive to FAT32, extracted the abobios.bin file from the exe file from the zip file on acer's website, then gave it any name I could find that may work, but still useless(fans spin to max speed, keyboard lights up, but only reads from the usb drive for about a second, after which it remains like this forever). I also tried extracting the image from abobios.bin with InsydeImageExtractor and gave it every name I could think of but still the same.
After this I extracted the image that it had on the bios memory. For some reason it is a bit more than 16 MiB
