Hello everybody,

Not sure I'm in the right place, if so please let me know where to post my question.

I had to replace a motherboard in a Dell Inspiron 5515, and the seller put a fake service tag - LK12345, I would like to change it if possible. Unfortunately, the motherboard is not in manufacturing mode.

Can somebody please give me some advice on how to do it?

Thank you.

Thanx in advance!

hi , i have a dell 3520 cyborg - 15 11th
while there is no bios lock , there seems to be a enterprise attachment
when i try to install windows 11 it just wont go past the account part , while i know i can bypass , i would rather change key or bios

i have attached the OG Bios could anyone give me a clean one ?

I have a Vostro 3420 8H8K5R3​-8FC8 that freeze at any attempt to enter bios password or the recovery master password received from dell. I do not have a clean BIOS image to flash.
And as luck would have it happened a couple of months ago right outside of the warranty period (Dec 2023) warranty expired in September. Any help or guidance is appreciated.

I've a FXMC motherboard with a short on the DCBATOUT line.The moment the charger is plugged in to the board, it will block itself for protection. I have remove PR4402 for isolating the short, and making sure the short doesn't come from AD+_TO_SYS.

Hi,
I wanted to modify 5070 board into 5070 extended variant (one with PCIe x4 soldered in) but from a few low quality photos I'm fairly sure there are more components missing than just the PCIe connector. Do any of you happen to have Wistron San Bernardino 16561-1 schematics and boardview available?
