I use a Samsung NP300E5C but it cant enter bios setup. Can anyone give me a stock non-modded P07RAC or P04RAC ROM?

I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.

You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.

Also, I uploaded a backup file for the bios that I extracted by using CH341A...

I have recently made a huge mistake using Intel FPT to flash a bios with an older microcode (I used UBU to replace microcodes) just to see if I can unlock undervolting, and the laptop failed to post. I have a CH341a programmer and flashed a couple of similar bios to no avail. I am wondering if someone has a 1:1 copy of my laptop's bios available. That would be very helpful thanks!

Hello everyone,

I need a BIOS for the Thinkpad L13 Yoga Gen 4.
S/N: PW05KQH7
Type Number: 21FR-0005GE

A recent BIOS update from Lenovo has bricked the laptop.
Currently there is no charging light.
According to Lenovo's website, the BIOS version R26ET41W/EC R26HT28W (r26uj08w) has been withdrawn due to issues with the system failing to power on after the BIOS/EC update.

Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....

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 also...

Hello, it seems to me that my thinkpad P50's BIOS is corrupted. I tried to boot it up and the power button would only blink 3 times green. The serial number is missing from the bottom of the chassis so I'm not sure what to do. I hope it's not the motherboard that's broken......

I have a MSI ge62vr Apache Pro 6RF. I'm having an issue with this repair that I haven't been able to find a resolution for with my usual sources, so I'm coming here on recommendation from Reddit. A customer decided to attempt to manipulate voltage to the fans through the EC, his laptop shut down and he was not able to get it to come back on. I did a power flush, EC reset, etc. didn't work. Took out my multimeter, no power was going from the charger to the battery. Checked with a different charger. Power was going from the charger to the inlet, but not the battery. Replaced the power inlet, and...

Everyone is buying the wrong CH341A programmer, I have learned from my mistake. Don't buy the Black one or Green one.
Buy this one in the photo. Most stable and all your common problems (reading but not writing/erasing, software hanging, disconnects after attaching chip, test cable connected but chip not found/ device disconnected) will be gone.

Otherwise you'll have to solder capacitor from GND to VCC if you have those symptoms in your black or green miniprogrammer....
