Hello, i've been trying to get a dump of my bios using wson8 pogo pin probe and ch341a. After sticking the probe to the bios chip, the lights from the laptop powered on for a split second. After I assembled the laptop, POST error appears (is it because I removed CMOS battery? not sure) but the laptop boots fine. Now, do i need to disconnect all the connections from the board before using wson8 pogo pin probe or should I continue knowing the first scenario about laptop lights and possibly might short something?

And another problem, after I connected the battery, the laptop automatically powers on, is it normal?
Also after I put the back case, the caps lock stayed on for a few seconds and can only be booted by plugging the laptop from charger. Hopefully I did not damage my laptop.

Thank you for your help.

remove the bios chip from the motherboard before reading or writing the bios chip, don't use the probe otherwise you might have errors... if you don't have an adapter socket for bios chips stick the bios chip on the programmer, or wires between the chip and programmer.. the laptop starts without pressing the ON button because you removed the bios battery..

thank you for your reply, now I can't boot my laptop. The charging led is blinking orange and white and the caps lock is blinking with long durations and whenever I put on the battery, it automatically turns on. What should I do now? any help please.

So after some research, and as staded in my first post, the 32MB Main BIOS also need to be hex modify to be able to remove password on-power start.
I download couple of old and modify bit to understand what member modify, without succefully finding a method to remove it.
Can somebody lead me what should I modify to remove this dump "on-power password" that why customer don't set, and witch even HP with warrenty won't take it and ask ridiculous price to fix it ...

Yes, it is possible.

Hey do you know if it can also work to remove user password for "power on authentication" ?
Maybe I do thing wrong, but same as Smiler, tool work and say unlocked, but power-on authentication is still there, can't acces bios to reset, so still stuck
Same laptop as Smiler, G7 830

Give this a try, flash only 32MB file, leave the 16MB untouched. And leave feedback if it worked.

First test, working fine, I don't want to reset security setting as I fear windows won't launch anymore, i gonna rebuild laptop and edit to tell if it boot into windows.

Edit : No need to reset security setting, boot into windows just fine

Thx a lot DanielDacko and RethoricalCheese for your awesome tool

Glad to hear that it works, not done by RCUnlocker as it doesn't support 32Mb files.

Big news, customers came in, try 3 times is windows password, couldn't find it, reboot twice, and TADAAA, power-on security kick in.
So I gonna flash again with you modify bios, reset security and default setting, clean SSD, make a clean install and I should be fine

Can I flash an older bios dump of the same laptop? because I updated the bios after saving and reading a dump.

yes.. you can write any bios version of the same laptop.. keep the original so you don't have problems.. and you can write it back when you want..
