Good day, I got one HP Zbook G6 with one BIOS bin SiZE 256Mb and on the other side of the board, the 128 Bios Chip was not there, it seems like someone removed it.

Help!

1. I have multiple BIOS chips so I want to reprogram 128 (I've tried to download 16MB BIN file from most of the posts but LED Keeps flashing)

I'm not sure if the Original Bios program from 256 Chip is not collaborating with the files that I downloaded for 128Mb Chip.


Please advise the way forward can the board be restored by only making use of 256Mb Bios program...

Would someone be so kind as to remove the password from my attached bios?

Many thanks...

Just a thread to post clean VSS2 files/dumps in.A clean VSS2 file can, in some cases, fix
the infamous [COLOR=#c0392b][B]**[/B][/COLOR]"[B]Endpoint Security[/B]" error message.
Be aware that if you use a clean VSS2 you may need to fill in missing DMI info using HP BCU !

I`ve included some clean files/dumps,offsets and a few scripts to autopatch a few models.
The offsets and file sizes are part of the naming convention i`ve used for the extracted
files.

So my customer spilled a proteinshake (milkbased) all over his laptop and I'm trying to fix it...

So I've been cleaning and reflowed the power ic which brought back the orange charing light. That's good.

Now I'm getting 20 V into the drain of the first power mosfet but only 8 V on the source and gate. Consequently the next power mosfet has 8 V at the source and something like 1.5 V at the gate.

Seems like a short is drawing voltage right? Any idea how to proceed?

Any help is appreciated. Thanks guy ...

Good Morning All

Currently working on zBook 17 G6 after fixing so many myself I've come stuck with this one.

Bios Chip was Blank when I Bought it. I flashed a BIN file from here which worked but serial mismatch threw up the Security Error.

I'm not experienced enough to edit the semi working BIN file and add the right serial. So I was hoping someone on here could use HP Recovery BIN, embed my serial and give me back a Bios and EC Bin please.

This is the serial from the back case. I haven't looked into the EC Chip for...

Hi,

While I finish reading the whole thread, I'll tell my experience in case it helps.

I want to remove admin bios password from a HP Zbook G3 and a HP Zbook G6.

-I bought a cheap eprom reader/writer and a sop8 clip
-downloaded software, installed drivers, etc in windows 11
-tried 1st with an old Dell desktop, located the bios chip, placed the clip, did several reads, verify, compare CRCs. Worked fine

Now let's try the real thing, the G3 bios is suitable for the clip, however the G6's is too shallow and bigger and would need a wson8...

When I wrote a 16MB file over the internet, the machine started and the image was ok.
but this error appeared:[B] HP Endpoint Security Controller Problem[/B]

I cleared the ME area but the result did not change. What exactly causes this error?

Hi, I have this laptop with a problem, when turning on every time it shows an error message for the HP endpoint security.

I tried and flashed a BIOS I found (U367-32Mb) and it worked for a couple of days before it showed up the same error again.

Can you help me get rid of this error. Here are both my dumps (U366 and U367)

I have some basic skills with Hex editors, if it isn't much trouble, can anyone explain what should I modify so if this problem shows up in another laptop I can fix it in the future?...
