Hi! I have a Lenovo s145-15api Ryzen 5 3500u, he need a bios reflash, i made that (tried with ch341a and ezp2023+). I tried a lot of dumps, and all do the same, so i think is a hardware problem. So after reflash, laptop work fine a short time, after some restart or power on/off, the laptop have again same symptoms, need a new bios. Do it again and again and same result. What are u think is the problem?

Hey guys,
Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.
Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27
Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit... -
Hi there,
I have a 14" Lenovo Laptop (Flex 5 14ALC05) which has a boot issue.
The little LED on the power button is flashing slowly and nothing happen.
This unit do not have any BIOS button cell battery so I tried many times draining the power but it is still not powering on.
So I decided to flash the BIOS using a cheap programmer.
And I was successfully able to read the content (exactly 16MB file) which BTW is a WINBOND 74m12jwsiq (according to the package inscription - but detected as W25Q128FW in the software - IMSProg on Linux)

I usually try to figure these things out on my own but am asking for help now as I have been beating my head against a wall.
Backstory, I initially ended up with a CF20 Mk2 with a locked BIOS. I used aptio to read the BIOS and made the adjustments to the .rom file and attempted to write it back with aptio before reading other users problems with that setup. Well it bricked the BIOS go figure. Computer no longer boots, black screen. I found a clean BIOS on this forum but now I am having ME issues. So I would rather hand over the aptio dump(pre BIOS brick) and a hardware reader dump(post... -
Hello,
I am trying to repair a Dahua NVR4216-4KS2 that is not booting.
The main BIOS/firmware is stored in an SPI flash EEPROM (Winbond 25Q128, labeled as U130 on the PCB).
I have a CH341A programmer and I already attempted the following steps:- Identified the correct chip (W25Q128, 3.3V SPI flash).
- Tried to read the contents with CH341A Programmer software. The dump seems corrupted and I often get the error: “Chip with the contents are in disagreement.”
- Compared several chip type selections (24Cxx and 25Qxx families) to confirm it is indeed a 25 series SPI
