Theres a reset procedure. I believe if you press and hold the F1 key while powering the laptop you should get a reset bios password. Google, reset lenovo bios password.

Testimonial: "i already did that and fixed the problem. it is F11 for my laptop and not F1 as mentioned in the solution.thanks anyway. "

When i turn on my laptop it ask for a password in blue and then there is a blinking curser and black screen it wont do anything after that unless i press f2 reapeatedly or f12 but i cant fix nothing on the...

There are two types of password:
1. BIOS password. To remove the BIOS password, the solution is, remove the BIOS battery. Location of the BIOS battery, the bottom of the laptop. So you have to unscrew the bottom of the laptop, find the BIOS battery and release approximately 7 seconds, then plug it back. Then, turn on the laptop, enter the BIOS by pressing F2, do the setting the date, time, etc.

2. Password Log on. When turning on the laptop, and log on, then we are asked to enter a password, but we never give password to log on. However, when we enter the password, always fails, it means the virus-infected operating system (operating system has been controlled by a virus). These cases often I meet, the Windows XP operating system is infected with the virus. The solution is to reinstall the operating system. Repair operating system, or breaking into password virus, I've tried, but always failed. So, the best solution is to reinstall the operating system.

If you are using Windows 7, you can fix with, insert the Windows operating system CD, then boot from the CD Room. Solutions you can do:

1.
Boot from CD Room, select Next - select Repair your computer - Next - select System Image Recovery

2. Boot from CD Room - select Next - select Install now - check the "I accept the license terms" - Next - select Custom (advanced). Then, select the drive where you installed windows - Next. Wait for your operating system install process to complete. Then enter your user name, etc.

After entering the desktop, don't open drive C, D, E, F, because the drive is still infected with the virus. All you have to do is, connect your laptop to the Internet, download anti-virus. You can use free anti-virus (Avira or AVG), then anti-virus updates. After the update is complete, do a virus scan, drive C, D, E, F. If a virus is detected, Primary action = repair, Secondary action = delete.


After drive C, D, E, F clean from viruses, you can open the drive C, D, E, F. You don't have to worry about losing data, because Windows 7, will backup your data in a folder Windows.old. In Windows.old folder, there are three folders: Program files, Users, Windows. Data stored in My Documents, can be found in the Users folder.

A SIMPLE AND EASY GUIDE ON HOW TO SETUP BIOS BEFORE YOU START REFORMATING YOUR PC

Usually, the only setting in BIOS you have to change is the boot order, so you can start from cd.
As for hanging, it might be dust. Yes, it does tend to overheat due to acumulating dust in the cpu fan.
Also, before you format, make sure you have all the drivers for you hardware and get the latest updates for your operating system, because you SHOULD NOT go online BEFORE installing the drivers, updates and the antivirus, in that order. I know it is a bugger, but reboot everytime the computer asks you to.
If you need more detailed explaining, post a comment. Meanwhile, I´ll research about the board.

I cant identify the prolem

It looks like you may have a boot sector virus. A boot sector virus is one that infects the first sector, i.e. the boot sector, of a floppy disk or hard drive. Boot sector viruses can also infect the MBR. All disks and hard drives are divided into small sectors. The first sector is called the boot sector and contains the Master Boot Record (MBR). The MBR contains the information concerning the location of partitions on the drive and reading of the bootable operating system partition.

When disinfecting a boot sector virus, the system should always be booted from a known clean system disk. On a DOS-based PC, a bootable system disk can be created on a clean system running the exact same version of DOS as the infected PC. From a DOS prompt, type:
    SYS C:\ A:\
and press enter. This will copy the system files from the local hard drive (C:\) to the floppy drive (A:\).
If the disk has not been formatted, the use of FORMAT /S will format the disk and transfer the necessary system files. On Windows 3.1x systems, the disk should be created as described above for DOS-based PC's. On Windows 95/98/NT systems, click Start | Settings | Control Panel | Add/Remove Programs and choose the Startup Disk tab. Then click on "Create Disk". Windows 2000 users should insert the Windows 2000 CD-ROM into the CD-ROM drive, click Start | Run and type the name of the drive followed by bootdisk\makeboot a: and then click OK. For example:
    d:\bootdisk\makeboot a:
Follow the screen prompts to finish creating the bootable system disk. In all cases, after the creation of the bootable system disk, the disk should be write protected to avoid infection.

Once the OS loads, run your anti-virus software and it should clean the virus.

Should this not help, I'm afraid the only other alternative would be to reformat the HDD and reinstall XP again from a bootable disc.

Hope that helps..
