The problem was in the firmware of the multicontroller. I selected the necessary firmware for the 32Mbit chip, everything worked. I left the original 64Mbit chip. -
Thinkpad W541 Works from the mains and charges the battery only when it is turned off
Lenovo Thinkpad W541 Wistron LKM-1 WS MB 12291-2 Works from the network and charges the battery only when it is turned off.
If you press the power button, the laptop turns on and works from the battery, but does not take power from the power supply.
If you boot into Windows and close the lid while working, thereby putting the laptop into sleep mode, the laptop begins to charge the battery.
even checked it this way: I bring a neodymium magnet to the Hall sensor during operation - the screen goes out and the battery starts charging.
Also, the laptop does not turn on without... -

Hi all. The problem is the same as many in this thread. The laptop turns on and turns off after a couple of seconds. I flashed the BIOS from post #2, but it didn't give any results. Can someone fix my original BIOS?

Hi all. There is a DELL Latitude 5400
MB LA-892P Rev 1.0 (A00). Came to me with a problem that takes a long time to turn on. After pressing the button, 23 seconds pass until the image appears. The BIOS chip has already been flashed. I don't have the original dump. Can someone help me with this problem? Here is the dump in the laptop.

Please help me remove the password. X412DK Rev 2.1 board
Laptop model F412D
The sticker on the case is worn off, I can't see the serial number. A sticker on the board itself and the original BIOS. BIOS from the official website and the BIOS that I flashed above. They work, but the fan constantly spins at maximum speed.

I doubt that something happened to the iron. I didn't even take the board out of the case. I'll make a correction, with another BIOS, which I also downloaded, the laptop also turns on but without an image. For the sake of experimentation, I erased the UT6 flash drive, the laptop started turning on but without an image. It won't turn on at all with your BIOS. Is it possible to corrupt the firmware in other flash drives? At startup, perhaps they are recording from the main one?

With your BIOS, the laptop does not turn on at all. I also found another BIOS on another forum, as they say it works, but the ME region has not been cleaned. With it, the laptop does not turn on as well as with your BIOS. When you press the button, the consumption changes slightly, quite a bit from 0.02A to 0.03A with each press. Is it possible that my patched BIOS, created based on the original, corrupted the firmware in other microcircuits during the first boot?Leave a comment:

I'll write in this thread because the problem is similar, only the BIOS was damaged for a different reason. Module DELL Latitude 5500 ST:GZW52Z2
I tried to remove the password using a patcher that I have and works on many models. But apparently something went wrong, and when turned on with the patched BIOS, the laptop turned on, turned the fan, but the image never appeared. I tried to flash the original BIOS, but with it the laptop also does not provide an image. It turns on, the keyboard backlight is on, the consumption is about 1A, then the laptop turns off, the keyboard backlight turns...Leave a comment:

Good afternoon. Help me unlock BIOS 8FC8 Dell LAtitude 7400. I have a patch that removes this lock, but it didn’t work on this model, this is the first time I’ve encountered this. The laptop just spins the fan and reboots. When I flash the original dump, the laptop turns on normally. Below is the original dump.

Hello . I have a problem with my Dell latitude 5580 laptop, la-e091p REV 2.0 platform. When turned on, it writes the error “tpm could not be initialized” and requires pressing F1. In the BIOS itself, the TPM module version 1.2 is disabled, there is such a function. I upgraded the BIOS version to the latest 1.36. I downgraded the BIOS version to 1.33, but the standard method does not allow downgrading, although downgrade is allowed in the BIOS. I cleared the TPM module in the BIOS. I turned off all the power, nothing helps. Can someone help me with this problem? And in general, could this be...Leave a comment:

Now I'm figuring it out. As I understand it, it is necessary to replace the 00 values after AMITSESetup. In some bios this happens once, in some 2 times. ALSO, the AMITSESetup register itself comes across a different number of times. Changed my bios. I'll test it now.

I did just that, and I also unlocked BIOS more than once, for example on the CF-53 model. But the meanings are always in different places. And another question: How to distinguish between MK versions?Leave a comment:

Helps remove BIOS password
CF-54C0481CM
6CTSA58083
I would be glad if they told me exactly how the password is removed. I have several of these laptops with passwords, we help and give them to the military. But I would not like to ask here to remove the password from everyone, but to do it myself. Can you tell me on what principle the password is deleted. Thank you...Leave a comment:
