Hi, Can someone please help me with my bios issue?
Lenovo T480s i7-8650u
TYPE 20L8-S48Y00
SERIAL PC-176NNG
I desolder the bios chip (Winbond W25Q128FV) to patch for supervisor password removal and I broke one of the pins on the chip. I soldered another bios cheap from a donor board (same chip model) and flashed so many bios dumps (including the one in this thread) but the laptop does not even power on. nothing happens (no lights, etc.) when I press the power. It only blinks 3 times when I plug the charger port in. Can someone help me with the issue and the correct bios file. Please note that the original bios dump is not available.
The issue is: No power, no display, no power light, etc when the power button is pressed.
Thanks in advance.Comment

Same problem. I removed the password from the BIOS. I flashed the patched bios. When turned on, music played. Turned it off with a button. The laptop didn't turn on again. I am attaching the original bios. (unpatched).

Hi all,
so I have T480s for whitch I've dumped the bios with NeoProgrammer and used autopatcher to patch the bios (to remove password).
Now the issue is that when turning on with patched or original bios power button flashes once and cooler spince for a second then stops, no other sign of life only cooler spining for a second every couple of seconds (no sounds, no lights - nothing else).

I'm attaching original (dumped) bios and the patched one. Please help - advise.
Thank you.Comment

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
