Re: hp Probook 640 g2 bios password
Can't agree about the clip thing. 95% of the time I use a clip on soic8 chips. It either works flawlessly or verification gives me an error which makes me read again. And errors almost always happen when I have broken a wire on my programmer.
It is more about what programmer and software is used and how the user uses them. Success comes with knowledge here.
But yes, reading unsoldered chips is easier but this doesn't mean that you don't have to verify what you read. It is always something you must do.Comment

Re: hp Probook 640 g2 bios password
Does not work.
Turns on the notebook, but the monitor does not turn on, the fan runs at full speed, the NumLock and CapsLock lights flash.
It also emits 3 beeps followed by another 2 beeps.
I left the notebook on for several minutes but nothing changes.

Re: hp Probook 640 g2 bios password
Dear friends.
With your help I managed to solve the problem.
When testing one of the versions sent by you, the notebook showed beeps and signals on the screen.
I identified that the 3 beeps followed by 2 bytes refer to a memory problem.
So I cleared the memory (one less problem).
after that, i cleaned the monitor connector (one more problem solved).
Then, after realizing that there was a signal on the screen, I placed the unlocked bin file that was generated by the programmer Ch341A version 1.32.
The notebook came back to life.
You are all great.
Thank you for the patience.
Thank you all.
I'm sorry if my English was not very clear.

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).
But today it's not accepting my password. I'm %100 sure i'm entering the correct password.
I'm trying to reset my bios without success.
I tried :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries... -
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.
My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).
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
I removed the BIOS password thanks to the help of one of the friends of this forum.
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
