Re: Dell Latitude 5430, LA-L591P Computrace setting unlock
Unfortunately not. When I press the power button, the orange light lights up very briefly and nothing else happens. Is it possible to solder in another BIOS chip?Comment

Can I install this chip W25Q256JVEQ Flash IC or does it have to be exactly the W25Q256JVEN that is installed?Comment

Re: Dell Latitude 5430, LA-L591P Computrace setting unlock
Hi, thanks for the file. With the new file flashed, I'm getting no power on the laptop and only an amber light when the button is held. I double checked the orientation of the SPI flash chip when resoldering it.
I only see 4 bytes of difference between the original and new files. Is that expected for this model?
Thanks!Comment

Re: Dell Latitude 5430, LA-L591P Computrace setting unlock
check well the soldering bin that the hardware friend gave you is correct, check if you blew any resistor or capacitor near the bios... if you are not sure upload an image of the bios chip and its surrounding componentsComment

Re: Dell Latitude 5430, LA-L591P Computrace setting unlock
Got it. Turns out I didn't have the wson-8 SPI chip aligned quite right. I removed and resoldered the IC on, and now the laptop is functioning great!
Thanks for the help!Comment

Not a BIOS request per se, but closely related. Please bear with me
A while ago I found an old Lenovo Thinkcentre M720q in pieces in the electronics scrap bin at work. There was only some minor damage to the case, so collected everything and brought it home to let it dry and see if it still worked. It did
Unfortunately Computrace has been activated on it. Since I'm using it as an emulation console with Lakka now, it's no big deal, but would be nice to get rid of the annoying message popping up when entering the UEFI setup, and also learn something along the way.... -

This sums up discussion related to Lenovo P14s Gen5 in this thread. Credits go to Sbaro and especially Maxpower3. The locked dump is attached.
The device is based on NM-F871 motherboard with Nuvoton NPCK397 series controller. The motherboard also contains three BIOS chips: two different Winbond chips for main BIOS and external EC flash, and also a Gigadevice chip which purpose I do not know. The password information is contained directly in controller and thus can be manipulated by reprogramming it, so reprogramming BIOS chips is technically not required, however you may wish to make...
