Secrets of Shorting or Cracking Laptop Bios Password Using Paperclip Revealed

This is actually the preparatory section where We make clear some things about the chip, CMOS, property and service tags, and passwords; so that you will have a good grasp of the big picture. BIOS chip for desktop

Hopefully it will also clear up whatever you have gotten a vague idea about on another website.

All pcs have special chips included that store information about the computer.

Some of them are made with long lasting information that are not able to be changed (and, as a rule, all have exactly the same information on them; thus not for passwords. ) These kinds of contain information about the computer model or are part of its useful circuitry. 

Another kind of chip (the kind our company is interested in) is created with a blank information area that can be programmed or filled up with information. These snacks are usually used to store settings and passwords; and come in 2 basic sorts: VOLATILE and NON-VOLATILE.

VOLATILE chips use a source of electricity to help these groups keep their information, for instance a battery pack. They are less expensive and are being used to store computer settings, and also passwords of all computer systems. If one of these chips has a security password onto it, the battery can be removed after a time (between 2 moments to 30 minutes, with regards to the chip) the password will be erased.

NON-VOLATILE poker chips don’t need electricity to keep their information, but are more expensive. When there is a password on one of such chips, it can be removed from power for years and still have the password on it. (However this does not signify it is long term. ) Remember that the information on Non-Volatile snacks can be stuffed with information. This information can be transformed or erased.

If you have check out this far you probably own a Dell or similar laptop with a security password that is actually stored in a Non-Volatile nick, or are an worker of a company that makes one. These notebooks have almost all of their setting up information stored in Unstable (inexpensive) chips, and their passwords are stored on a tiny Non-Volatile (more expensive) chip.

The computer chip that Dell uses is called a 24C02 processor chip.

This is the Computer chip Type number used to refer to the chip’s design in the gadgets industry.

The 24C02 is a small, rather common surface mount* dip* nick with 8 leads (or legs), which costs about $5. It measures 4. 5 mm long a 3. 5 mm large x 2 mm extra tall, and stores 256 Octet (or one quarter of the Kilobyte) of information. That is frequently used in modems, DIMM Memory, and other electronic devices; and a different condition it can be used in many wallet measured “smart cards. ” 5. SURFACE MOUNT means that the chip is soldered onto the surface of the printed circuit, rather than having pins sticking through the board. This can be the most difficult type of circuitry to solder by side.

* DIP means ‘Dual Inline Package’. This means that the chip has 2 rows of leads (or legs) in right lines running down their sides.

That’s the computer chip we will be interacting with, or read the “Some unnecessary information about the chip. ” section later on.

The laptop that was used in this demonstration is a Model 630 type PPX. Other laptops may be different from the main one shown in the full break down demonstration photos.

If a certain laptop does not correspond to some of these layouts, more information might be seen on the web, or, anyone not reading for informational purposes only – could plan to simply “Wing it. inches

As well, the chip containing the password may have a different location on some motherboards, but it should be capable of being found by reading the numbers on the top of the chip, although a magnifying glass might be necessary.
