Re: HP ProBook 650 G2 6050a2723701-mb-a02
I forgot to add the attachments. Screenshots are for Probook 650 G2. The process for Probook 650 G1 was the same, although for some reason the DMI tools were started within Windows 10, while for Probook 650 G2 were started at startup level (before loading the OS), as you can see in the screenshots.
Additional tools that you might want to experiment are (although they didn't help in my case):

Re: HP ProBook 650 G2 6050a2723701-mb-a02
Update:
I managed to successfully flash BIOS, first on a HP ProBook 650 G2 (chip Winbond 25Q128FVSQ) and then on a HP ProBook 650 G1 (chip Macronix MXIC MX25L12873F), using in both cases the firmwares provided by SMDFlea.
I include hereafter some notes based on my own experience:
1) Neoprogrammer seems to do the work better than CH341A Programmer and AsProgrammer. Using the latter two you have to be very cautious which version of the software you will use in order to correctly support the chip(s) you're using.

Re: HP ProBook 650 G2 6050a2723701-mb-a02
Doing some googling, it seems that this is happening to several users. See for e.g. [url]https://www.badcaps.net/forum/showthread.php?t=80676[/url].
Some people say that the reason is that the AMT function of the motherboard has not been defined properly (AMT-enabled or not). This might be true because the BIOS firmware I programmed (650 G2 01.49 Rev.A N76 ME_CLEAN.BIN.zip) does not give any AMT options during BIOS setup (F10), something that my previous BIOS did have (I know this from the config file I exported using...Leave a comment:

Re: HP ProBook 650 G2 6050a2723701-mb-a02
After several attemtps it finally worked!
To be honest, I had to plug and unplug the charger several times before and/or after the programming and also play a lot with powering on/off the laptop. I believe it is also important to make sure that the machine is completely switched off by pressing the power-off button for 10 seconds or so before starting the programming. Finally I used Neoprogrammer but I am not sure if it matters.
After being able to boot properly in Windows, I tried to restore the configuration...Leave a comment:

Thank you for your valuable feedback!
I didn't know that for HP laptops I need to have the charger plugged in! Are we sure about that? Several people say the opposite. As for the CMOS battery, good tip, I didn't know that I need to unplug/remove it before programming.
My case is N76 based on an export that I got using the HP BIOS Configuration Utility (BCU) before starting playing with programming the BIOS. More specifically, the System BIOS Version is "N76 Ver. 01.00 12/07/2015", the...Leave a comment:

Re: HP ProBook 650 G2 6050a2723701-mb-a02
Could somebody from the experts providing the bin files explain in more detail the process of creating these bin files? In my case, using a test clip, I am able to flash successfully the bin files but afterwards the laptop is completely dead. It only happended with one of the bin files that the laptop started behaving like with the fan at 100% and black screen, however I am pretty sure that I tried the very same bin file again a couple of days later and this time the laptop appeared to be dead.
Some quick questions:
1) Shall...Leave a comment:

Re: HP ProBook 650 G2 6050a2723701-mb-a02
Thank you, I will try tomorrow and report back.
Unfortunately backup is not an option anymore. The original backup was faulty and ever since I have already reprogrammed the chip several times
I forgot to mention that the BIOS chip is Winbond 25Q128FVSQ.
Do you know if #99 .bin file is compatible with this BIOS chip?...Leave a comment:

Re: HP ProBook 650 G2 6050a2723701-mb-a02
Hello,
I have an HP Probook 650 G2 with N76 BIOS and ME firmware version 11.0.0.1194 as shown in the settings backup I got using the HP BIOS Configuration Utility (BCU).
Unfortunately the .bin dump I got was faulty (exported with CH341A 1.34). Now I am using AsProgrammer 1.4.1 and I have already tried a couple of .bin files attached in this thread but no luck. I also tried the latest .bin from HP site for this model but same results. Please note that the .bin from HP site is about 9MB while the one I exported - the faulty one...Leave a comment:
