SOURCE: dell latitude d630 forgot bios password
Go to Dell support and download the latest BIOS revision. When you flash the bios it should wipe out the password. The second option is not as appealing.... open up the laptop and remove the CMOS battery for 30 seconds. This is much easier on a desktop, but a proven solution if there is no other way.

SOURCE: dell latatude D630 is docked/battery flashing 4 red 1 green
4 orange and 1 green can mean a battery malfunction, or it could be an indication that the battery is about to reach the end of its life cycle. When a battery is built, it has a planned expectancy. a date code is stamped in the electronics of the battery pack. as that date code is reached, the indicator lights on the computer let you know the battery (even if its working fine) is considered obsolete and needs to be replaced soon.
