I can't open bios of T30 ThinkPad IBM computer because I do not know bios passwords.I want to know way of open?

if you've forgotten the BIOS password, you'll have to check with IBM. Often, they have a way, usually a temp password like method that you can use to disable the BIOS password. for desktop systems, removing and reconnecting the coin-cell battery or a password reset jumper can be used, try to check the manual of your laptop if that applies to you as well.

Cant remove my bios password on my IBM Thinkpad A21m

Dear Sir,

Getting around the Laptop BIOS password is tricker then the desktop...I don't know if your system would go passed POST or either case, there are few software out there that would allow you to clear the bios.....but you need to do some reading first...

Check out this site: search for this section "Password cracking software" , you will find four software which may help you out (please note that you have to be registered user in order to download the software.

I need to reset the power n password for ibm t42

This varies from laptop to laptop, some ibm laptops have a special memory chip for the password that will prevent users from reseting the password.

In most of the laptops out there you can remove the bios password by removing the 3 volt memory battery inside, but in ibm laptops there may be a rom chip that stores the password, so it doesn't get removed even after removing the battery, there was some work around solution posted online somewhere, but its not guaranteed to work.

IBM t42.. I don't know if this laptop has any special bios password protection.

Try removing the internal battery and see if it helps, leave it unplugged for a while.

if this doesn't solve the issue theres probably a rom chip that stores the passwords, the ibms are made a little better than the average laptops out there, not as easy to bypass.

if you get a system disabled xxxxx code if you enter the password wrong 3 times this may be unlocked at a local ibm service center, even I could give it try since I have access to some of the manufacturer code calculators.

if the bios battery didn't solve the problem and you don't get a disabled message either, then you might have to sort a few pins on the bios chip to reset it, thats something you will need to look into on your own and do at your own risk, theres also the guide somewhere online for creating a tool to remove the password.

last option is to take the ibm to a service center to get it unlocked, this one is the best and recommended option for you.

I have a ibm thinkpad t20 and when the internal battery died the computer started asking for a password when booting up. I know how to reset the password on a desktop but this thinkpad has me stumped. Can...


the default BIOS password for this model is merlin but if that doesn't work you have a hard drive password set and may for lack of a better term be screwed. You can try zero wiping the harddrive from another system assuming you have the right cabling/adapters.

If the Hardrive is locked but the BIOS password works you can also acquire a new hard drive cheaper than a password cracker in most cases.

Hope this helps FixYa,

Disable boot up password in R51

You could open up the R51 and remove the CMOS battery. This would reset the password.

Here is a link I found that allows one to hack the BIOS password:

I set the power on password on my ibm 600e and now cant turn it off. How do I do that

go to go to support page, download the service manual of your model first, it will show you how to reset your bios password or remove your bios passord, usually remove the bios password, it is your CMOS battery (look like a calculator battery) unplug it, and put it back on again, your bios password should disappear. make sure remove the battery first.
