I am trying to convert a HP EliteBook 840 G7 notebook from a non-touch to a touchscreen. I purchased a complete touch LCD assembly with a screen/back cover/bezel/video cable and swapped it out with the original non-touch LCD assembly.
The screen works but the touch does not. I know the new LCD assembly is completely functional because we tried it on a similar touchscreen EliteBook 840 G7 and the touch works there.
I contacted the seller and he said screen conversion like this will not work due some difference in the motherboard for non-touch and touch capable EliteBook 840 G7.

Yes, these files worked for me. The password was gone and I had to use BCU to get out of the manufacturing mode by filling out empty fields. Otherwise, computer is good to go. Thank you.

After reflashing the bin files, caps lock is blinking 7 times.

Ok, I am attaching original bin files. So, this one has the admin password in it. If you could just remove the password, this should fix my other issue as well....

Hi, I have a Elitebook 840 G7 laptop. It had a admin password until got rid of it using a bin file in one of the postings.
However, on every boot, I am getting "There is a problem with the HP Endpoint Security Controller". Can you help me remove this message from popping up?

I am also attaching both bin files....

Thinkpad T15p Gen 3 BIOS cleanup requested
Hello,
I have this Thinkpad T15p Gen 3 laptop. It starts normally with keyboard lighting up, I can hear the fan starts spinning, amps quickly reach about 1.7A without the battery, CPU gets hot. However, it is not posting.
I suspect the BIOS is corrupted. I am providing 2 BIOS files as I see 2 BIOS 256Mb chips. I am also providing a photo of the chips' location on the motherboard.
Model: Thinkpad T15p Gen 3
S/N: PF-45G6VM
Type: 21DA-000PUS
Motherboard: NM-E221
Thank you....

Hey, thanks. Computer is booting into Windows now.
However, every time I reboot I get a message "Manufacture Programming Mode is in Unlock Mode" followed by "Warning : OEM Keyboard Type is not set !!!"
Can you modify the bios file to rid the computer from these messages or is there an HP utility app that can remove these messages?

CPU getting hot immediately in this machine is normal according to my experience. It is also normal for the BQ chip as well as QB6 mosfet to get really hot, sometimes going to 90c+ within seconds. Do you have an IR camera?
PU4 getting hot does not mean it's faulty. There may be other components influencing it to get hot. Make sure at least you get 20v, 5v, 3.3v and 1.8V rails available.
Measure the capacitors nears the EC chip. I've had cases I was getting all these rails but the computer would just refuse to start. Then, I'd find several shorted capacitors near the EC...

I went to HP support website and downloaded an utility program which created a bootable flash drive with the bios file on it specifically for this computer. I have done similar things many times before. On start press Windows/B Key/Power Key together. After a few seconds release the power key and keep holding the other 2 keys. I did that and the aformentioned message came up. Usually, computer immediately reads the flash drive and begins to install BIOS.

After reflashing the bios chip with any of these files, I get the following message "The system BIOS Pending Image is being cleared. Do not shutdown or remove power from your computer during the clear. The clear will take a few minutes to complete". Then, the screen went dark.
I let the computer sit for over an hour without any movement.
May be I am doing this wrong. Are there 2 bios chips or just 1 bios chip? You provided 2 files which are extracted from HP website for bios recovery.Last edited by trepachka; 04-22-2024, 09:56 PM.

Motherboard information is below:
HP Part# M52826-601

It needs BIOS repaired.
I created a flash drive using HP firmware utility and then had it plugged into the computer. I did the standard WinLogo->B key->Power button press. A window appeared and immediately began flashing the bios using the flash drive.
But I don't think it finished all the way. So, now when I attempt...

I have this Ideapad Flex 5 14ALC05. Upon hitting the power button, ESC and CAPS LOCK keys light up, the fan begins to spin, the amps quickly go to 1.3A. Then, the fan stops spinning, amp draws a steady 0.5A but no video.
I tried various bin files from this thread including 2, 25, etc. The one that worked for me was 23. Computer boots now with no issues.
