Slow Start HP 640 G2 Probook - Bios

I understood.
This is the original Bios file that was unlocked with the tool posted here on the forum.
Could someone clean it for me?
Thank you.

I tried to use the "Intel Easy Clean Me" program, but it doesn't recognize my notebook's bios.

I did the test, but it doesn't start.
The LED on the numlock and capslock keys flashes 5 times
Attached is the updated bios that was working.

remove the bios chip from the motherboard before reading or writing..if you use the clip you may have errors..use the chip adapter..search the internet for video tutorials, depending on the programmer you have.

I identified that the bios chip I was using for testing was defective.
So I saved the new BIOS settings on the original chip.
I tested it with the two versions that you modified and with an older one that I had saved.
The notebook turned on, but the charging time is the same.

I downloaded this bios from the HP website, but it is smaller than normal.
I believe it is only for updating.
How do I add information about my notebook to make it work?

Made from the bios in the first post, and the update on the HP site.

The loading time is the same.
It is stuck in the BIOS loading for 30 seconds and after you start to load the system.
Only a few times did it start quickly with the previous bios, but these were rare cases.

Hello friends.
I did the tests with these BIOS images, but it didn't work, the startup time is the same and ended up disabling some motherboard peripherals.
So I decided to leave the original configuration.
Thank you for your help.

Do you have an original bios backup, the one before you removed the password.

The first file is original.
I just erased the password line manually.
The rest is the same.
