I have a Lenovo Thinkpad T470 with a now damaged tamper protection switch. I can't access the system BIOS to disable the error message as the unit hangs at the error (and then displays a perfectly blank screen when I press the ESC key). SN:PF11JCWY TYPE 20JM

Hello. I need to unlock the bios, which is user-locked. I think it doesn't require a disk, which I don't have. I don't know what to do, and I don't want to ruin the laptop. I unsoldered the winbond 25Q12BJVSQ chip and loaded it. I'm attaching the file. I'm not sure if it also depends on other U15, U49 chips. I could still manage U15. Thank you for any advice.

Read the other posts above you. It should say something like PF-1X2Y3C

Everything works, keyboard backlight and lights, but no image and after a few seconds it plays some melody. Can you wait for another option? Or put it in the closet for a year until it gets easier? I guess I should see the logo there so I can move on. With your patch, the display won't show anything.

Nah leave the closet out for now. We will fix it Inshaa'ALLAH
FIRST flash Type_20HE_CSME_Clean+WinKey and WAIT for your machine to boot
Only then proceed with the following steps in the correct order

1- Now Flash Type_20HE_CSME_Clean+WinKey_PATCHED
1- Boot the machine and Press ENTER/F1/etc. to enter BIOS settings
2- Enter any character when asked for Supervisor Password
3- Press enter when it shows Hardware ID
4- Press space bar 2x when asked and then Turn off machine
6- Flash back Type_20HE_CSME_Clean+WinKey
7- Reset BIOS settings to factory default

PS: When booting the patched BIOS you might have to:
1- Hold the anti-tamper switch down the whole time (use tape)
2- Remove the hard disk or replace it with a locked one

Lenovo T470 (Type 20HD, 20HE) Laptop (ThinkPad) - Type 20HE
Machine Type Model 20HES18902
BIOS Version 1.69 (N1QET94W)
WinKey/880000-88FFFF

Motheboard K.O. I damaged the surrounding millimeter resistor. So I'm done. I can send it to you if you want to take a look. We can discuss it via private message.

[Sparo]

That shouldn't be a major issue (K.O.), it can be fixed once you're ready to try. Just solder it back on, or replace it if the resistor is damaged or missing
Here's a schematic to help you identify the exact resistor value by locating the component name (e.g. R32) > https://www.badcaps.net/forum/troubl...ic#post1366761

Hi everyone:

I have a T470 here with a dead battery. For that reason, I'm using Winflash64.exe to bypass the battery check while doing a bios/EC update. After a lot of trouble, I managed to flash the BIOS update via winflash64.exe. However, when I try to update the EC via the following command:

winflash64.exe /ipf ec /file $0an1q00.fl2

I get: ERROR 081 - Failed to load BIOS image file!

I know the BIOS version and EC version should not be mismatched. Can anyone suggest where to go from here?

Thanks.
