HP EliteBook 840 G1 Base Model Notebook PC...

Hello all, I downloaded from this forum BIOS dump and flashed the above laptop which initially wasn't displaying anything. It worked, but after a couple of months it has started a strange problem.
When I press the power button, it comes on but no display, I have to plug in the charger, then pull out, then plug it in again for it to display.
I have included both BIOS and (I guess), EC dump for anyone with a know to look at it. Thanks in advance.

I am also attaching a bios below that has a password.
hp 840 g1 serial: cnu8309h9r / product: d1f44av
can someone help me with this bios to remove the password?

thanks​

With the help of this forum, I was able to restore an old HP Elitebook 840 G1 to life.

What puzzles me a bit is that I did not need to enter all data into the bios-config utility to achive that.
On the initial power-up after replacing the bios chips some scary warning appeared that this was attempt 1 of 10 (max?) and some data was missing or invalid.
However, after a while the message disappeared and this message was displayed:

EC MPM and System MPM Mismatch
System needs to restore system information
... will take a few minutes...

Hi there,

after I broke the bios chip (leg broke off during soldering, probably a manufacturing defect; it came of with a chunk of the plastic case), I am trying to get the box working again with a replacement chip.
For that I need to set a valid BUILDID and FEATUREBYTE. The Mainboard is Rev. 730804-001 and originally Windows 7 was installed.
There is no sticker on the case and partssurfer does not have that information either.

Would anybody be so kind to look at the info screen in the bios and copy those for me?
I would like to install linux on this...

Hi!

I have received an HP Elitebook 840 G1 to remove the Admin Password from. The Laptop worked fine, just had a BIOS Admin Password set. I have made multiple dumps to verify the hashes, when accidentally I clicked the "Unprotect" Button in ASProgrammer and after that the Laptop doesn't boot anymore (Backlight is on, Power LED is on, Capslock LED is blinking..)

Hello, I'm going insane these couple days trying to do a motherboard swap on a hp elitebook 840 g1 and i'm going to ask for help on this very friendly looking forum.

What do you think about the second one which is completely burned? It is the top circle.
Do you think is the same as here? [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/89930-hp-elitebook-840-g4-charging-problem/page2[/url]
First post on the page.

In my opinion, HP EliteBook 840 G1, G2 and similar 820, 850 or same generation are pretty much the same. The next one HP EliteBook 840 G3, G4 or G5 can be very close in this part, as well. And all of them can have pretty much the...

Greetings badcaps community,

I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

I learned that desoldering...

Hi all,

I cannot unlock the Bios of an HP EliteBook 840 G1 :
- With RCunlocker I got the error message "[I]missing unlockable content[/I]" (However, I operated correctly on the 16 Mb Bios chip - Winbond 25Q16DVSIG - I can also read the serial number of the computer on it).
- With HP-unlocker, I have no error message, but the output _.unlocked.bin file is identical to the original file (same checksum).
I add that I started again several times.

Thanks.

hi i need bios bin for hp elitebook 840 g1 6050a2560401-a02...

I have this EliteBook 840 G1 laptop that won't start - it blinks on the caps- and numlock buttons 3 times which indicate issue with the memory modules. On one of the memory slots of the motherboard, I can see some corrosion (?) and my guess is that it's creating a short. At first I figured I could just omit using this slot but it wont start either way - also tried other RAM sticks of course.

I've tried to see if I could clean it up, but the laptop remains unbootable. Can it be because it has caused issue elsewhere or because it's still shorting in the memory module?
