Hi,

I've been working on this for about a week. I've read the threads and ordered and attempted to use a programmer to pull the BIOS dump from the laptop with no luck. I tried using RcUnlocker, but keep getting a dll error even after reinstalling the C++ Redistributable. I also tried NeoUnlocker and another program. None would pull up the chip.

That leaves me asking for help unlocking this BIOS. The laptop boots up to the Domain login with no issue. I can pull up the boot menu. Any attempt to open the BIOS or the BIOS upgrade menu is met with a password request....

Hello all,

First time posting, so please be gentle 😂

HP Elitebook 850 G2 Win 10 with Intel HD Graphics 5500.

Screen dead, but booting.

I connected it to an external monitor via both VGA & Display Port outputs and external monitor works fine, nothing with F4 or detecting another screen in settings.

Got a replacement panel, still dead & still displayed to external screen as before.

Removed CMOS & left it. CMOS reconnected, all as before, no panel, external monitor works.

Got replacement cable...

It's not good for you

A friend gave me this laptop years ago with Windows 10. Since Microsoft will not support Windows 10 next year I'm planning to install Linux on this laptop. I just found out that It's has a Admin password and I had to disable the secure boot so I can install Linux in this computer. Please help. Attached are the dump files.. Thanks...

Hi,
here are the steps that worked for me:
1- CH341A with SOP8 adapter for the 25series chips(bought on amazon) & SOP16 clip (bought on amazon). Check if the jumper on the CH341A is in "programmer mode" (jumper betweeen pin1-2)

You have a laptop that does not power on, powers on but shows no image, crashes, etc… You want to fix it but you don't know where to start.

There are 2 situations:[LIST=1][*]You just want your laptop fixed[*]You want to learn about fixing laptops[/LIST]

Sorry, but if you're in situation number 1, we recommend you to use the services of a trustworthy professional repair shop.
Unfortunately, if you're not serious about learning, you will waste your time and money, and you will make us waste our time as well.

If you are in situation number 2, then...

first boot press f10 apply factory defaults and restart.
use BCU. you can permanently disable Absolute lock in BCU.

I solved it like this :
Install windows 10 and download HP BIOS config utility, navigate to the install folder via command prompt, run this:

Hi Everyone,
I faced a strange issue of my friends laptop.
You might have an idea because I'm out of my deept here.
The laptop starts every time no problem.
- When The original 230W charger is plugged in (with or without the battery same) and I start installing windows or start a preinstalled windows, then WHEA error happens or black screen freeze.
- When I start laptop with only battery then windows installer start fine, install goes nice and fast. After installation I have to disable the nvidia 1070 and start windows this way and then enable the Nvidia 1070...

Hi! Need help for repair this unit. Problem not typical.
All voltages are present (CPU, GPU, 5v, 3.3v, charging system).
When I try to install Windows it's shutdowns automatically (in 10-15 sec after it recognize flash drive)
3.3V and 5V have a good resistance (kOm's). 5V when work drops to 4.8v, unstable.
I bought 2 laptops with same issue. I think maybe it a typical problem.
Motherboard - DAG3HIMB8C0 REV.C, Quanta G3HI.
Can anybody help? Thanks

Hi,
Can you unlock the bios dump of HP X360 1030 G4 for me, please? I did the unlock exactly as it was done on X360 1030 G3, but it seems that it doesn't work for G4 version or I might just messed up something. The other thing is that I have feeling that the bios comes back to original state (being recovered) maybe from some IC like a keyboard controller. Is it actually possible? I have no KBC programmer.

For some reason I can't upload bios dump file because of error:

"Your submission could not be processed because a security token was missing.

Hi all

We have in a HP ProBook 445 G8 laptop with AMD Ryzen 7 CPU. When power is connected the power LED light blinks 5 times then stops. Normally HP laptops will blink this LED 10 times as it does a self test when the AC adaptor is inserted. So there must be some sort of short somewhere.

The battery doesn't charge, and is erratic on the MM voltage. Bench PSU LED pulsates when the battery is connected also. So the fault must be on the charging circuit?

I have gone around the board with a MM and cant find anything

Windows shows the battery fine,...
