Hope this helps

try the following; phoenix, PHOENIX, CMOS, BIOS
If that does not work you have two options.
1) remove all power and all batteries for about 15 minutes (there is a battery on the motherboard) and it should reset to blank. 2) if you can boot there are various bios hack programs to reset the bios but I would only do this as a last resort. I absolutely do not trust someone to hack the bios if I can avoid it.

The BIOS password may be removed by removing the BIOS battery from the notebook for 20 mins. If you cannot wait for this period, then short out the battery contacts for a few secs.
Replace the BIOS battery and go to the BIOS configuration and set the Date & Time etc.
If this procedure does not work then try this WEB site for BIOS passwords :-

Most machines have a jumper to reset the BIOS password.  Sometimes, you just have to remove the coin cell battery and wait a few minutes for it to clear.
Try looking on NEC's website for that specific info on that model.
At any rate, it CAN be cleared out.

try to remove the battery and plug into AC.

you can also try to recharge your battery (if it is still working well) for a few hours before turning the laptop on.

let us know.

First you need to take the cover off your laptop and locate the cmos battery which looks like an oversize battery watch. With everything unplugged it just pulls out, note which side of the battery goes however. Place the new one in put everything back together and power the computer up. When it powers up it will finally get to the screen that says press "F1" for setup or "F2" to continue. Press F1 and you will get to your set up screen. You can go through each screen and select F5 which is the default factory settings or scoll across the top to the last screen which will give you the option of resetting all the settings to factory default with just pressing one of the F keys once only. Once you do that, just shutdown your computer and restart and it will start as normal. It may go through the F1 and F2 screen one more time but just press F2 and continue. After you log off the next time all your changes should be good. Let me know if I can help you in any other way.
