Remember that laptops can be trickier, especially if it's a newer model. If it has a security chip on the motherboard forget about it. You either have to physically remove the chip or contact the mfg for the "master" password. If you can boot up off of a cd or floppy try any of these methods:

1. Create a Win98SE bootable media "or anything that lets you boot into MS-DOS" and boot off of it.
2. When the A:\> prompt appears type debug and press enter.
3. You will then only see a "-".
4. Type o 70 2E "include the spaces" and press Enter.
5. Type o 71 ff "include the spaces" and press Enter.
6. Type q and press Enter.
7. Here are a list of common mfg backdoor passwords
