Hi All!

I am new here and hoping to get some help with my Dell Precision 5510. I am fairly certain that the BIOS is corrupt. I get no Dell logo, no POST, no option to get into BIOS settings. This started after disabling secure boot and attempting to boot from a USB drive. I tried using the firmware recovery steps provided by Dell and have not had any luck with that. So I think the next step is a direct flash to the BIOS chip(s). I have a CH341A arriving tomorrow to do a dump of the current BIOS. What will I need to provide in order to get some help recovering this BIOS?

Greetings comrades:

I am nearing the home stretch of my BIOS recovery project; however, I reach a point where I must ask a community of hopefully astute members who would help to send this project across the finish line. I successfully completed the BIOS extraction with a Python utility which produced a pair of outputs that I have attached as a Zip file. Frankly I do not know what to make of such results and wondering I can proceed to program the chip with the System BIOS with BIOS Guard [V0 AMI] v2.42.0.bin or I have more work to do for preparing the files for re-flashing. I will...

Had Bios Rev. R01-A4

Was trying to update the bios and the system froze on the post screen with an RST/SMART error about the hdd.
Forced a restart at which point the fans and case leds would turn on but the screen would stay black.

Read through the guides on how to get the bios .bin from Acers .cap file and i am unable to figure it out.

Hello everyone,

I have a Lenovo Yoga Slim 6 14IRP8 that got stuck in a BIOS recovery loop after a BIOS update was interrupted through Lenovo Vantage.

Here are my device details:
- **Model:** Yoga Slim 6 14IRP8

- **OS:** Windows 11 64-bit

**Problem:**
Every time I boot, I get the message: "Do you want to recovery ROM part? (Caution: Not every OS is bootable in Recovery Mode.)" with two options: YES or NO. The screen just stays there with both options and does not do anything on its own. When I...

Hello,

I have two laptops with the same problem. When I connect the charger, the charging light turns orange. When I connect the charger i get 3 white blinks from the power button, the fan starts spinning and then stops, and the screen stays black.

I have checked the voltage at the battery and it indicates that it is charging. I searched here and found that many people have the same problem.

I have read the BIOS from both laptops and will upload them here. I will try to flash the BIOS and then check for a hardware problem.

Does anyone have information...

Hello,

The BIOS on this laptop is corrupted.

Hello to All.

Kindly I need main bios and EC bin file for mentioned motherboard above.
I have a attached picture where ic's are marked (next to PCH is main bios, next to Nouvoton is EC firmware chip). So I need bin files for these chips, because someone before made a mess with them and they are currently empty.
Furthermore, I try to find on net for the very same board bin files, but for this version, no luck. Revision version is 1.02.

Thanks...

Hi Guys,

Unfortunately, I put a password when I bought the laptop to protect the BIOS, and I can no longer remember it.

If I could get some assistance to unlock the BIOS, I would be very grateful.

BIOS password locked Dell Latitude 3440 (Service tag B4HNJX3)
Have extracted the BIN and want to know how to rebuild a clean BIOS

I have come across the 8F8C patcher but not sure if that would work in my case as the service tag ends in 0001.
I tried it and although the log states it patched several mentions of 8F8C in the BIN, I haven't flashed it yet in case such a patch wouldn't work.

Have also tried to extract a clean BIN file from Dell's .exe BIOS updates using 'Dell PFS Extractor', but not confidently; Ended up with a 25MB file instead of the same 32MB...

Hey everyone,

I recently bought a Dell G15 5515 with an AMD Ryzen 7 5800H and 3060 RTX. The BIOS chip on it was dead, and my hardware guy replaced the chip. After that, everything was working fine.

The BIOS is currently at version 1.22.1, and I wanted to update it. I downloaded the latest BIOS version from Dell Support using my ST: FQZMYJ3, but when I tried to run it, it says "unsupported system." I asked my tech guy what he did, and he said he took the chip from another board and flashed it onto mine.

When I check the BIOS using the F12 menu Flash...

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....
