Question BIOS problem with Lenovo L480

[mica_antenica]

Hello everyone

So i was a bit too stupid and I broke my laptop and i need help. So here is what happened;
I have a Lenovo L480 and it had a power on password which I forgot now I wanted to use an auto patch and fix that but I didn't have a CH341A flasher and I did but it on AliExpress and I didn't want to wait cuz I need it asap and u waned to flash it with Arduino.

Now here it comes, my stupidity;
I made that flasher and it didn't work so I was thinking maybe I need to remove bios chip I did remove it in one place but I accidently removed one SMD component and while I was dumping a BIOS flasher broke and erases my chip now I in the end both a CH341A locally for a bit more money and I tried dumps from everywhere found and no luck laptop powers on for split second and after that all light lit up now I do have in some dumps a file for a second 1 mb chip do i need to flash that also?

Impatience is often the path that leads to more trouble than good. As it stands I don't think your issue is with the BIOS chip, it might very well be that you knocked out that SMD. I'm speculating here since all you've included is text of your predicament. On second thoughts, if you didn't regulate the voltage using your Arduino, then yes you've ruined the BIOS chip too.

We're going to need some images of what you knocked off the laptop's motherboard and perhaps the orientation of the BIOS chip if you desoldered it and then resoldered it.

@Lutfij alr i will send you shametics that u found the borad view and all photos that i have from that that and i can xonforim that the bios chip is in right place

Edit: You are right next time i will 100% check If I have all right tool and not to diy somting that is cheap to buy but useful.

I don't need schematics, just images of the board.

@Lutfij here is a photo Photo

Edit: i chect that part with multimeter and it is connected to scip seletor pin now if I looked good in shematich that pis is connected to somevwre on borad with 0 ohm resistor never mint if eas a wrong thing
