Re: Hp ellİtebook 840 g5 bios password
Hi.
There is an HP EliteBook 840 G5 with a BIOS password. There is also a programmer, an adapter and a chip. 3.3V is set on the programmer, everything works - it was read / erased / written / checked several times. I'm waiting for another chip and a probe (yes, I read on the forum that it's better to solder the chip). Perhaps important HP BCU considered:
Sure Start BIOS Settings Protection
*disable
enable
Have questions:
1. The status of computrace is not yet known. Suppose it is active, in which case which of the dumps needs to be modified by the BIOS or/and EC ?
- BIOS HPunloker + BIOS HxD (computrace 3F --> 3C)
- BIOS HxD (computrace 3F --> 3C) + EC RCUnloker
- EC RCUnloker + BIOS security reset on first boot
...
2. If I use a probe, then turn off all the power or leave something connected in a special way?
RethoricalCheese, can you explain the nuances for the HP EliteBook
3. Do I need to reinstall the operating system after the modification?
Thank you.
p.s. please forgive me for detailed questions, but I don't want to get a non-working device and have backups on original chipsAttached FilesPremium supporters get full download access and other benefits.

Re: Hp ellİtebook 840 g5 bios password
Notebook displays "Protected by HP Sure Start" under the HP logo while booting.
After loading the operating system, the BCU shows options:
Sure Start BIOS Settings Protection
*disable
enable
HP Sure Run Current State
Inactive
Sure Start Secure Boot Keys Protection
Disable
*Enable
SureStart Production Mode
Disable
*Enable
After modifying the main BIOS on the first boot, will it be possible to enter the BIOS to reset the security?
And yet, there is no identifier in AbtState, but Asset Tracking Number = Serial Number.
Do I need BIOS HxD (3F --> 3C) in this case or not?Comment

Re: Hp ellİtebook 840 g5 bios password
Hi all!
Probe delivered. But the situation is bad. All 5 readings gave different results.
The situation by region is in the attachment.
"+" - match
"-" - difference
Is the 3rd reading correct? For flashing, the chip will be soldered.Attached FilesPremium supporters get full download access and other benefits.

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
Hi everyone,
I’m a student currently locked out of the BIOS on my HP EliteBook 830 G6. I bought the laptop second-hand, and the previous owner didn't provide the password. I really need access to the BIOS to change storage settings and boot orders for my studies.
System Details:- Model: HP EliteBook 830 G6
- Processor: Intel Core i5 (8th Gen)
- Serial Number: 5CG0080LKD
- Halt Code (from 3rd fail): qeh11u1kst
I'm hoping someone here can help me generate an SMC.bin file or provide a master password that works for this generation. Any guidance on how to get back... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello Hello,
I have been browsing the site and gotten so much useful info from here, including extremely helpful boardviews and several other very useful types of information. I am very grateful to this community, as I have actually eeked out a living from buying salvage PC's & Macbooks and repairing them. So, thank you all in advance!
I have searched and found some useful information regarding my issue, but my case is a bit different than the info I'm finding. But if anyone here can give me any useful advice, it would be highly appreciated.
