                              Got this hp elitebook 840 g8 that is flashing orange light when charger is connected. no power.
                              Apparently it had locked bios, but it went somewhere before coming here so I dont know what they did to the dump...
                              I read EC+BIOS and post it here.

                                i have tried a lot of them. no one works. i think maybe building one using the original one is the best chance here. thx

                                  Hello,
                                  I need help with an HP EliteBook 840 G8 BIOS repair.

                                  During the removal process, I accidentally lost the original BIOS chip, and unfortunately I don't have a backup of the original dump.

                                  I found a clean 32 MB BIOS file from another HP laptop with the same motherboard model, but now I need to insert my laptop-specific information (DMI data) into this clean BIOS image before flashing it.

                                  The information I need to restore includes:
                                  • Serial Number (S/N)
                                  • Product Number / SKU
                                  • System Board CT Number
                                  • Feature Byte
                                  • Build ID
                                  • MAC Address... ETC
                                  I want to modify the clean BIOS file using HxD, but I don't know where exactly these DMI fields are located in the .bin file...

                                  Can someone guide me on how to manually locate and edit the DMI region (NVRAM region) inside the BIOS dump, or confirm the correct offsets for this model?

                                  Thank you.

                                      Bios password removal on a Unowhy dump
                                      by Buzzfuzz2k
                                      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

                                      Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware

                                      Hi all,

                                      This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

                                      I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

                                      I...

                                      TONGFANG "GM7TG7P" Bios Password Problem?
                                      by traxformania
                                      Hello,

                                      I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

                                      But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

                                      I'm trying to reset my bios without success.

                                      I tried :

                                      -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

                                      Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

                                      My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

                                      Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

                                      I removed the BIOS password thanks to the help of one of the friends of this forum.

                                      The batch from which the password was removed works correctly but... after some time, the BIOS password is set again, I reprogrammed the batch with the removed password, it's ok, there is no password, I set my password, ok, I can enter the BIOS with my password but...
