Is this a Windows log in password or a bios power on password?

    I have wrestled with IBM bios passwords. Most of the time I ended up replacing the motherboard, because the security chip that IBM uses was impossible to get around, and the way it's built onto the motherboard caused damage when removed. I'm going to suggest three things, 1- contact IBM or check on their support site for clearing the bios password, 2- look on line for various fixes for this. I can tell you that I've tried several, but none worked, and 3- contact shops in your area to see if they can clear it. This is the best advice I can give you, there is no simple fix for this, sorry.

Ibm thinkpad r52 no hard drive detected


The hard drive may have dislodged from the HD terminal. Some early laptops didn't reinforce the connection here. There is a bay under the laptop with a HDD or O)) symbol that opens with a small Phillips screwdriver. There should only be 2-4 screws on the bay panel. Open the bay. The hard drive should be firmly connected to the computer. Make sure the connection is good, then replace the bay cover and screws.


Start up the computer...Update the post on your outcome.

Hi I have an ibm thinkpad R52 and recently the batt gave up on me and it took a while before i was able to get it back on. But when i turn it on. The bios is asking for password and i dont know what to do...


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

In case of your IBM 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 am using IBM R52.. now, i forgot the bios password.. what are all the options to reset the password?...


Thinkpad R52. There is a very good piece of software that you can download from Sourceforge.net. Its a linux software but works very well. Once you download install on a CD. This IBM has the ability to actually store three separate passwords for it's hardware before you get to windows. The toughest being the HDD (hard drive)password. This password is embeded in the boot table and cannot be removed because of the nature of it's function.

Good luck
