An enigmatic French invention, The Paperclip, will be used to master and overwhelm the power of one of the marvels of today's cutting edge technology, the microchip.

First the paperclip which was requisitioned at the beginning of the procedure is gotten in hand; if it has not been lost or misplaced by now, otherwise another conveniently available paperclip is used.

The paperclip is then unbent and, stripped of its paper-clipping function, is reformed into a totally new implement which looks like this:

Next, the location of the actual chip is sought out. It is located here on this particular model.

And the best shot I could take showing its location.

Now that the chip has been located, a closer look must be taken at the actual chip itself. This is both because this procedure will involve working rather closely with certain leads / legs on the chip, and because the correct identification of the chip in question should be verified before anything further is done.

Also if this particular model of laptop is different from that may be being worked on, the chip may be in another location and a good view of what it looks like will aid in being able to find it.

Here are 2 close up views of 24C02 chips.

The arrows indicate which pins / leads will need to be jumped with the paperclip.

This is roughly what the 24C02 chip will look like on your motherboard. The letters or precise arrangement or numbers / letters may be different. But, you will be able to see (possibly with a magnifier) that on the top row, 24 and C02 are printed, possibly along with other letters or numbers, depending on the manufacturer, or series of the chip.

You can use the direction of the writing and / or the location of the small indented spot shown in the bottom left hand corner of each chip to identify which pins / leads need to be jumped in order to clear the chip.

The paperclip will be used to jump (or make a temporary electrical connection) between these 2 pins of the chip, as shown here:

You should be able to see that these are the same 2 pins which were indicated by red arrows in the previous pictures of the chips.

Now the power adapter is plugged in and connected to the laptop, but the laptop is not powered on just yet.

With the laptop open at roughly a 90 degree angle, and lying on it's back, the 2 indicated pins are jumped (or connected by touching one with each end of the paperclip) while the power button located on the other side, near the keyboard, is pressed, turning it on.

The laptop will turn on, and a screen like this should appear. Fn-X may be pressed if desired. Also, setup may be entered by pressing F2. And the paperclip, if it hasn't already been removed, should be.

It is now possible to enter setup and change all the values.

Also note that all system passwords have been cleared.

But you can not use the password feature anymore, because the chip has been cleared of its information. This seems to be another not very well thought through security feature. The next page will show how the chip can be reprogrammed to allow the password feature to be used, if so desired.

* Hard disk drive passwords are not cleared or removed by this procedure.
