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 Filesif you find these attachements useful please consider making a small donation to the site

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 Filesif you find these attachements useful please consider making a small donation to the site

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,
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.... -
Hi guys,
If someone would be able to provide some expertise, I'd be very grateful.
BIOS Corruption - Cause
So I managed to corrupt my machine by installing linux and enrolling custom secure boot keys. I did choose to enroll the Microsoft keys as well, to prevent any potential bricking due to 3rd party drivers from HP being signed with those keys.
After doing that, and rebooting(it did boot, powerLED, fanspin etc.), the laptop did not give any video output on the LCD or video connectors. I think I was able to get in BIOS and trigger the beeper by pressing ESC....
