I have HP TC4400 Laptop and there is BIOS password which is forgoted please help me how can i remove that password.


To reset the BIOS password read the information from this link.

In case of your HP TC4400 laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

I need reset bios password Notebook HP Compaq 2710p


I know some methods to reset bios password.
1. The best and easiest method: Close OS and shut down the electricity power of computer. Open your computer box, take out the cmos battery from the mainboard. Then the bios password will be reset to blank. Put it back after a few minutes.
2. Follow some hard tutorials, it is difficult to do. It is better that you are a expert. For example this tutorial: reset BIOS Password?

So I would suggest you the 1st method. Hope it helps.

Disable BIOS Administrator password


Enter BIOS SETUP. Enter the current password.
Change it to a "blank" password.

Or, if you don't know the password, find the orginal sales-receipt, to prove to HP that you are _NOT_ a thief in possession of the stolen computer, and then HP will assist you.

I need to reset the bios on my Compaq TC1000. I tried removing the RTC battery and replacing as HP suggested but that didn't work, They then suggested I need to flash my bios. I cant find instructions for...


To flash the BIOS you need to download the BIOS from a link which HP provides.. so contact them and tell them to provide you with the BIOS link..
You need to download the BIOS and install it..
However after removing the RTC battery I would suggest you to hold the notebook power button for 20 secs..
This should remove all the residua power..
I think it will remove the BIOS password...
If it does not work then you could flash the BIOS..
What sayy???

Want to reinstall OS on compaq tc4200. don't have passwords..


If the BIOS password is set, you'll need to return the device to HP/Compaq to get that reset. Only other option I can think of would be to whip the hard disk out and see if it'll boot from a CD at that point. If that is the case, you could theoretically put the drive in another PC, wipe it completely and then reinstall it. The machine will try to boot from HDD, fail and then boot from CD next.
