Can you reset a BIOS password on a laptop just like on a desktop by removing the battery for a while? I am considering purchasing a Gateway that the seller is "locked out" of.

Thanks.

Would be nice to see a reset jumper on the notebook motherboard? unfortunately I haven't seen any that has that, so removing the Battery was my only choice...

Yes, but the 2 bateries, the standart one and the one that is inside the laptop, so prepare to disasemble it!!
Not so difficult, you will find the cmos battery, most times pluged through wires.
Also watch carefully for a jumper too.

No you cannot reset as a desktop would,it has been suggested to let the battery power drain down and then you can reset the password,then recharge the battery.

This DOS trick (deletes) your Motherboard BIOS (CMOS password), to grant your computer and BIOS Setup once again, If you have forgotten or lost it.
Exit Windows or reboot to the native MS-DOS mode using the ?Command Prompt Only? (use your start-up disk) or hold shift and F5 at the same time while your PC boots.
At the C:\> prompt, type: DEBUG and hit enter. You will see a dash (-) at the DEBUG prompt. Now type :o70 2e, which will show as ?o70 2e at the DEBUG prompt. Hit Enter, Then type: o71 ff and hit enter.
Finally type Q and hit enter one last time, to quit Debug back to the C:/ Now you are ready to reboot your Pcand press the appropriate key or key combo to acess your BIOS Setup. You will notice that the password has gone.
**Note :this only works with MS-Dos6.00-6.22 and MS-DOS 7.xx(a.k.a. MS windows 95,98,ME)**
