I forgot the dos password and cannot start my laptop.How do you clear the dos password in laptop?

In: Laptops [Edit categories]

Answer:

You're probably referring to a BIOS/CMOS password - a password that you need to enter before your laptop will even begin to start the operating system (DOS/Windows/Linux, etc).

If that's the case, then I know that for a desktop PC, you can sometimes clear the password by setting a jumper on the system board, and briefly powering on the PC (a jumper is usually a pair of metal pins that you can "short" together using a small plastic piece which contains a metal bridge). Another option is to remove the BIOS battery, unplug the power supply from the wall, and let the CMOS "forget" it's settings.

While the above is technically possible with a laptop, you'll find that they are harder to open up, and easier to damage once open, so unless you're very comfortable with your laptop, or don't mind calling it a doorstop, I'd recommend a quick search on the web for "CMOS PASSWORD RESET" + {your laptop make/model}. If nothing obvious, simple and quick turns up, then find a good local laptop repair person.

Hope this helps.

Cheers!
