What do i do with the EC file? I have found a 25B62CSIG chip on the mainboard and flashed the bios.bin in it but the laptop still does not start.

the EC bios is for the I/O chip ... write the chip back
25b64csig, with the original content ... I hope you made a copy before writing it ...

Thanks a lot, i fixed my V320-17IKB with your BIOS file

Hi! I think i have a Lenovo 320-17IKB. There is a sticker but ther is no information about product or serial number on it..
The laptop powers on for 3 seconds where the screen seems to go on, cpu fan is going and power led is on but for no reason it powers off.
After disconnect all of the components that may be halting the power on, i think is a bios related problem.
Is the first time that i try to programm a bios, i just bought a CH341A usb programmer BUT i think i MAY be wrong about the bios chip.
Can someone tell me what the chip is? I think is the WinBond 25Q34JVSIQ but i'm wrong?
The modo is a DG421 DG521 DG721 NM-B242 Rev.:1.0 2017-01-25 with vendor:PALWONN.

Thank you so much!

You look for any chip with the number 64 on the back. Ex: q25w64..

On the back there is nothing. On the top there is the chip that I mentioned before. I attach some photos. Thank you so much for the help!
The third photo is the chip that I think is the BIOS.

Thank you so much!
At first I was certain that it was right but then I saw it was near the GPU and i thought that i find the wrong chip 😭

Tomorrow that comes the programmer, what are the steps that I need to follow?
Read, save the readed config, and then? Is my first time doing it, I readed a guide online but if the bios file is broken how do I repair it? 🥺

It is essential that you make a good backup first before erasing the chip.When you have made a backup post it here,don`t erase the chip.

Tomorrow i will post here the backup.
Another question: to know at what voltage the chip is, i need to find it in the datasheet? I bought a 3.3/5v programmer, i saw after the purchase that i could buy it with a 1.8v adapter too. I need it or i'm okay with what i got?
When a bios is broken, is common that it losts the DMI (?) informations or they likely stay there?

The chip is 3.3V .If you make a good backup the DMI info could still be readable,then its easy for one of our members to transfer it to a new bios for you.There could be some corruption in the backup,enough to make reading the DMI impossible.Reading a bios chip with a clip is notoriously unreliable,so make 2,3 or more backups and compare them.

I know but because i'm new in all of it i did not want to spend a lot, if this become more and more frequent, i'll buy some more quality stuff.
I'll listen to you and make more backups.
To do all the thngs, the pc need to be connected to the power right? Battery connected and ext power?
I'm so sorry for all this questions but i want to make sure that i do all the procedures right

No power. AC , main battery, CMOS.

Okay, with power i mean just ac plugged but no on because eather way it turns off by itself.

It arrived this morning and i'll do the backup when i have a little bit of time

I'm currently reading the BIOS but idk what i'm doing wrong... the reading is all FFF's...
I selected both W25Q64JV and BV but nothing.
The usb stick have only the "Power" led active but no other one led is working, like "run".
I installed the driver from the folder of "AsProgrammer". What i'm doing wrong? T-T

Edit: tryed installing NeoProgrammer and says "IC not responding" even if i am connected to it.
They gave me a faulty programmer?

Hi. I managed to have the bios files (it was the programmer faulty).
I used both AsProgrammer and NeoProgrammer and saved in two different folder. Visually seamed to be different so I saved both.

Thank you so much.
