The BIOS file I downloaded from BadCaps works fine.
However, the serial number is missing and not visible.
Please help.

Hello, first and foremost - sorry for hijacking this thread.
I bought Lenovo S540-15IML that powers on with no image. After initial inspection and bit of googling I found this topic and I thought it was the same issue as stefanbs had, although mine was not water damaged - so I swapped the resistor for memory config to disable onboard memory, but to no avail. I tried multiple RAM sticks to be sure.
With original BIOS in place the laptop turns on, the consumption jumps from steady 30mA when off to somewhere around 500mA and jumps around a little, then settles on 400mA forever. No image, +VCC_GT missing.
I tried BIOS from THIS TOPIC, post #15. I tried BIOS from current topic, post #28. Same story. I also tried stefanbs's dump, but the laptop won't do anything - instead of turning on it almost dies taking only 4mA. Then jumps back to 30mA.
So anyone has any clue what might be wrong? The CPU is doing something, but stops and draws steady power. I believe the missing voltage on VCC_GT (and thus no image) has something to do with the POST failing somewhere along the line. All other power rails seem to be OK.
Serial number: YX000W4S
Original dump attached. But I believe it might be wrong as someone was already messing with the Winbond chip before me.
Thanks for any help.Comment

Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM -
Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM -
Hello!
yesterday I received from eBay a Lenovo M92p TINY model 3238 system with 4GB of RAM and a 500GB mechanical HDD.
I tested it and it worked fine, it booted to a fresh Win10 x64 French OS .
The plan was to replace the mechanical HDD with an SDD one and upgrade RAM to the max 16GB since I had 2x 8GB SODIMM modules.
I noticed that there was an update on the Lenovo support site so I thought I'd do that first and then proceed with the upgrades and installation of new OS.
The windows BIOS update completed successfully and the system booted to a bios-like... -
Hi! I have a ThinkPad e495 that doesn't turn on anymore after being shutdown accidentally during a bios update.
When I try to turn it on, the power button flashes rapidly about 5 times, the caps lock key stays on, and cannot shut it down by pressing and holding the power button. I've tried disconnecting the battery, and it turns off, but then again when I turn it back on it does the same thing.
I suppose I need to flash the original bios, and even got a ch341a eeprom programmer + 1.8v adapter. I have a couple of problems with this, first the bios file on lenovo's website has a fl1... -
