    Alienware 17R2 BIOS chip location

    Hi there, this is my first post, just hope it is in the right spot.

    I have an Alienware 17R2 whose motherboard is LA-B753P. I downloaded the latest BIOS file from Dell website and now it is bricked. I googled everywhere and it seemed to use a programmer to reflash BIOS is the only way (and the cheapest way) to solve the issue.

    So my question is: is there anyone who can tell me where is the location of BIOS chip location? I know it is a little silly but from the pictures I found through Google, it seemed that there are more than one 8-pin chips on the motherboard, one is close to the killer wifi card and another one is close to CMOS battery. Really appreciate if anyone can let me know which is the right one to reflash.

              Thank you for your reply. Yes, I found this method in another website,

              https://www.bios-mods.com/forum/Thre...-unlock?page=9

              it also provided some extra suggestion with putting the exe file and a renamed BOOT_IMG.rcv in USB.

              I tried both, but, unfortunately, neither is working on my laptop. I think it is totally dead

                  Schematic here: https://www.badcaps.net/forum/troubl...753p-schematic according to it, BIOS chip is UH4 and a windbond W25Q64FVSSIQ, bottom of page 19.

                      Oh Thank you so much Mazorca. It is good to know UH4 is the right one so that I don't need to pull the whole motherboard out. Thanks!

                              Q: Why is my bios chip unreadable ?.

                              A: The programmer is faulty or has a worn or broken zif socket.

                              The USB cable is frayed,connector pins worn or some other physical damage.

                              Not enough amperage or voltage to power the programmer properly.

                              My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
                              1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
                              2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
                              3. I could only locate two chips that look like bios chips. Could someone verify this

                              Asus Chromebox CN62 - wrong chip put on BIOS reader
                              by BMCappelletti
                              Long story short:
                              - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
                              - gave the computer to his son a couple years later
                              - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
                              - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
                              (seems like the story was not that short)

                              He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

                              Hello, first of all, excuse me, I am using the translator, English is not my native language.

                              I have a Lenovo ideapad 330S - 14IKB laptop.



                              The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

                              Alienware Aurora R15 accidentally flashed with XPS 8960 BIOS
                              by drux
                              Hi,
                              I've had an ssd that was previously used on dell xps 8960 and then it was installed in Alienware Aurora R15(intel version). On first windows boot in R15 windows started bios update and loaded bios for xps 8960(r15 and xps8960 essentially have same motherboards).

                              Now it has xps 8960 bios that looks different from alienware bios and when I'm trying to run bios update files for R15, I get unsupported platform error.

                              These models have AMI/Aptio BIOS.

                              Tried to edit product info with DMI Edit to change values back to Alienware R15, but it does not want...
