When I turn on my laptop:- The display backlight turns on, but the screen remains black. I can see that the backlight has power.
- The keyboard light turns on, and I can toggle it on and off using the backlight button.
- The fan spins for a second and then stops.
- After a while, even though the screen is still black, I can hear the Windows boot sound.

Hi, can someone help me please with the removal of the bios password of this dump.
Someone desoldered the bios chip, tried several "methods" but with no luck, and he gave me the dump to try to search some help.
For now he deleted more things and bios password is gone but laptop doesn't show serial, model etc.
Also, I updated bios to latest version, when he will write the dump again without password, it should be better to put back the old version that was orignally or doesn't matter? Because from what I've read this laptop has 3 bios chips, don't know if has... -

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

Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.
I have a few questions:- If I would buy this laptop and have

Hello,😇😇😇
I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.
🔧 Model: HP ProBook 11 G2
📦 Serial Number: 8CG72478MY
🆔 UUID: 6F5ED686-5532-11E7-A2E2-911C6404E011
🔒 BIOS Status: Locked with password
The laptop is no longer under warranty and HP refused to help me.
I’m looking for a custom SMC.bin file.
I don't have a CH341A programmer, so it's difficult for me to provide a BIOS file.
Thanks a lot for your help!🙏🙏🙏...
