Re: hp Probook 640 g2 bios password
the bios doesn't seem ok..the half is empty ..Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

With the 1.30 version we get an error message "access violation at address 0097ea42"Comment

Re: hp Probook 640 g2 bios password
Its 3V . Try AsProgrammer software it works ok with the CH341A. Choose SPI on the right side at the top, then from the dropdown menu at the top left,choose SPI then winbond 25Q128FV .Are you using a clip or have you desoldered the chip.

Hello,
I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

I'm trying to reset my bios without success.
I tried :

Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set.... -
Hello

https://www.badcaps.net/forum/troubl...61#post3637661
The batch from which the password was removed works correctly but... after some time, the BIOS password is set again, I reprogrammed the batch with the removed password, it's ok, there is no password, I set my password, ok, I can enter the BIOS with my password but... -
Can someone help me explain how to fix the original bios when downloaded and exacted bios is much smaller than the original one?
Thank you very much
