    13-aw0023dx BIOS PWD Removal

    Got an HP 13-aw0023dx here and the owner set and then forgot the BIOS power on password

    For giggles, I tried a BIOS dump someone had posted in an earlier thread for a corrupted BIOS on this same model, which apparently came from a similar but not exactly matching model, but the system doesn't even post with that. I also tried the HP emergency BIOS recovery option (Winkey + B + power) but while it does go through the motions and reflash the BIOS, at the end it still prompts for power on password.

    I've attached a dump of the BIOS.

    use RCUnlocker and unlock it yourself..you don't have the password in this bios ... look for another bios chip on the board ..

      Re: 13-aw0023dx BIOS PWD Removal

      Thanks for the tip. Wasn't aware of this tool, it looks great. I'm wondering though if it works for power on passwords or only BIOS password lock? I can see that it says "missing unlockable content" if I drop my dumped bin file onto it. When I open the bin I uploaded in UEFITool it appears to be structured like a valid BIOS dump, from what I can assess based on my limited familiarity.

      I've attached pics of the Winbond chip I dumped and the only other two that look like possible alternate BIOS chips, Winbond 25q80dv1g and MXIC mx25l8008ezni.

        And attached is the BIN file extracted from the latest HP BIOS download for this model.

          Re: 13-aw0023dx BIOS PWD Removal

          Odd thing here, I tried flashing a BIOS from a previous posting (https://www.badcaps.net/forum/showthread.php?p=1000108) for the same model that the OP had said worked but was slow to boot and displayed mfg mode msg and got no post. reflashed the original bios dump and it still doesn't post. it will occasionally boot into bios restore mode with winkey + b and go through a restoring bios process but then it shuts off and won't post again for a number of tries. Trying to understand how the BIOS backup restore feature works on this model and what it may have to do with the issues I'm having. Any thoughts?

            use version 086F9 from post # 4 in this thread.. if you have the same motherboard.

              I tried that 086F9 bios and it doesn't post. Also when I restore my original BIOS dump back to the chip it still doesn't post. I can get it to go to BIOS recovery mode by holding Winkey + B while pushing power button and it goes through the motions of restoring the BIOS backup but they instead of rebooting it just powers off and won't post again.

                Re: 13-aw0023dx BIOS PWD Removal



                Main BIOS chip is highlighted. Is there another chip I need to dump / reprogram?

                    OK, that highlighted chip is an MX25L8006. A dump is attached

                        MX25L8006 is not bios chip. Check below picture, it's look like a WSON chip. Lets me know name of that chip

                                If your model is HP Specter x360 - 13-aw0023dx, chip bios must be 16MB (eg 25Q 128.. with Winbond chip).

                                    I tried the bios dump you posted, hp-13-aw0023dx-pwd-unlocked.zip, but get only quarter fan spin and short power cycle, no post. You also posted this EC bin file however, but I'm not sure which chip this is for?

                                    On the bottom of board there is SLB9670 TPM chip next to IT5570VG-256

                                      Re: 13-aw0023dx BIOS PWD Removal

                                      Also, to return to a previous question, I'm trying to understand how the system seems to be in a worse state now than it was originally. I backed up the primary winbond bios file (dump was attached to original post), then tried flashing the 086F9 bios recommended by peste and but it did not post. Normally I would think that should be no problem, since I had made a backup of the bios before any modifications, and I reflashed that original bios backup, which should have restored the system back to it's power on password protected status. Instead, the system would no longer post normally, and the only way I could get a response out of it was to startup with Winkey+B whereby it would go through the motions of performing a BIOS restore from previous version, but at the end it still would not post. So clearly what I had thought of as a safeguard, backing up the main bios chip, was not sufficient in this case. What explains that?

                                      And thanks to peste, smdflea and everyone else for suggestions, just finding this one to be a headscratcher.

                                        I think you wrote or read the bios chips with errors..from the beginning when you read the bios chip you read it with errors..that's why when you put back the one with the password (original) the screen is black...or maybe not did you stick the bios chips well.. which programmer did you use?? if you use this clip it gives errors... you have to remove the chip from the motherboard before reading or writing..

                                          I need a BIOS dump for the Samsung S49CG934SU monitor
                                          by Habble7
                                          The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                          Suspected Cause:
                                          I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                          Troubleshooting Attempts:

                                          Bios password removal on a Unowhy dump

                                          Hi Everyone,

                                          I'm facing a problem with a locked bios with a password and i can't find how to remove it...

                                          The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).

                                          the Computer is a Unowhy small pc

                                          After failling trying to boot on other "none Windows" partition, i wanted to try to remove the bios password.

                                          My first attempt was to get the bios dump from windows...

                                          MSI PRO B660M-G DDR4 - real bios dump from board needed (no stock bios)

                                          Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).

                                          I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...

                                          This laptop is the same laptop I was working on in this thread and I wasn't sure if I should post a new topic or post in that thread because I already solved the issue that thread was discussing and this is a completely different issue although it is dealing with the same laptop. I decided to make a new thread since it's a new issue, but please move if I made a mistake.

                                          Who has a MSI Z590 PRO WIFI - Need BIOS dump ?
                                          by DynaxSC
                                          Hi,

                                          I need a BIOS dump for MSI Z590 PRO WIFI from a real physical board, along with MAC address and serial no.

                                          It must be a dump from a physical board, as it contains personalized data eg. MAC Address, UUID, Serial no.

                                          I have a board which has lost the BIOS contents, I have the MAC and serial to this board, and need to insert it into the another BIOS image. To do it, I need to have a real image from a real board, as the images from the MSI site are without this data. The only way to find where MAC/UUID/Serial is located in the BIOS is to have a bios...
