Change the user name to Administrator. Leave the password blank ! This should work.

Back up your most important data to an external storage device in case anything goes wrong while changing the BIOS settings. Remove any disc that is currently inserted in the IBM Thinkpad X41's disc drive.
2-Shut off the Thinkpad X41 laptop. Turn the laptop back on and wait for the "To interrupt normal startup, press the blue Access IBM button" message to appear on the screen.
3-Tap the blue Access IBM button at the top of the keyboard. Click the "Access BIOS" button when the "Rescue and Recovery" menu appears.
4-Click "Yes" and wait for the BIOS to load. Type in the current BIOS password for the IBM X41 and press Enter.5-Navigate over to the IBM's "Security" heading by tapping the right arrow key twice. Scroll down to the "Supervisor Password" listing and press "F5."6-Type the IBM's current BIOS password and hit Enter. Leave the next field blank if you want to completely remove the BIOS password, or instead type in a new password to replace the old one. Press Enter.7-Press "Escape" and then highlight "Restart" and press F5. Navigate to "Save changes and Restart" and press Enter.

Hello,

I'll asume something for this one it might help. Make sure your laptop is completely turned off [No fans turn, screen black, no hard drive light]. When you then press the power button, immediately keep pressing the F8 button on your keyboard. It should then actually display two options after a while :

*Delete restore/resume point and start windows
*Resume restore/resume point

Select 'Delete restore point' and the unit should boot up fine again.

I had a unit that was basically turbo-booting into windows, but the restore point was corrupt and it always seemed it had a 'blank screen' problem.

You can also try to access the BIOS by pressing F2 as soon as the unit starts up to see if you can actually access the BIOS.

If that all doesn't help I suggest reseating RAM.

Go back into Safe Mode, and try to run a system restore to a date where this issue did not exist.

if it was the video card ...it will appear something on screen like Bios...when accessed..and affect only the installation ...I suspect the lcd connection
so...assuming is nothing inside...take a look on this tutorial

Sounds like the laptop is trying to display a resolution that is not supported. Try to reboot into safe mode or the BIOS. Try safe mode and if you can get into safe mode make the default screen resolution something like 1024 x 768, then reboot and see if everything comes back.

It sounds like damaged OS (virus maybe).
You need to reinstall/recover the operating system.

Hello nic208, The problem is you have a BIOS level password installed. Laptop owners and computer departments sometimes install them in case the laptop is lost or stolen to prevent unauthorized users from gaining access.
