Compaqs usually have what is called a &quot;backdoor BIOS password&quot; that is usually used for testing purposes, the password is &quot;compaq&quot;, try it then change the password from the BIOS setup.<br />
<br />
If that doesn't work you can use CmosPWD that is available here: <a href="http://www.cgsecurity.org/wiki/CmosPwd" rel="ugc">http://www.cgsecurity.org/wiki/CmosPwd</a>&nbsp;to retrieve the password.<br />
<br />
Hope that helps!<br />

Pull the doors on the bottom of the laptop. Locate the cmos battery, assuming compaq designed the notebook with acces to the battery. Unplug it for about 10 min. Plug it back in and start, this should clear out the bios. Also make sure the laptop is unplugged and the battery is also taken off. If this doesn't work than you will most likley have to follow nobus instructions and contact compaq &quot;HP&quot;.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
