HP 6735B Bios recovery

Hello.

I just wonder if there are any procedure for recover/flashing bios for this model 6735B?

I tryed to take out battery,cmos etc, And it says that time/dato has been changed, but still asking for bios password.
Im working at a school, were we use WDS, when clicking f12, it ask for bios password.

Do anyone have a solution for this? thanks

Hi,

 

Unplug the laptop, remove the battery and hold down the power on key for 60 seconds.  If that doesn't fix the issue then read this article near the bottom.

Thanks for the reply.

But that did not work for me.

 

I got a feeling its not possible to reset this bios password the normal way.

I put BIOS password for that model in Google and it showed a YouTube video on how to do it (but it is not English and I did not watch it all) Give a look: http://www.youtube.com/watch?v=qSnhzFy14d0

 

BTW: I am not responsible for any harm that may come from that video's instructions.

Re: HP 6735B Bios recovery

Im not sure how it works for the laptop but for the desktop there is a 3pin switch in the motherboard called CMOS clearing.  It is three pins next to each other and there is a connector connecting like pin 1 and 2.  you take the connector out and put it on pin 2 and 3 and turn on the compute. you turn it off and put the connector back on 1-2 and that is how you clear the CMOS password.
