Dell Latitude D505
To anyone who has short circuited a latitude D505, i would just like to ask at what time's did you use the paper clip. I have tired around 30 times at jumping the eeprom at diffirent periods of time and none as of yet have worked. In a pdf i got from a member of this forum it said to:
"Short circuit the 24c04 or 24c05 during booting and release when the cursor at the display flashes. If this don´t work, short direct after you pushed power and release when the cursor at the display flashes. If this don´t work at first time, try it again and again."
However, what ever i tried did not seem to work. In many cases i would conect the wire to short circuit the eeprom, in which case the Bios would load almost to the end, and then the computer would restart by itself, the bios would then load again. After loading a screen would be displayed saying:
Primary hard disk drive 0 not found
a cursor would then flash for a moment i would try releasing the wire here, but this did not work. And then shortly after that cursor would flash another line would be printed to the screen saying:
No bootable devices--strike F1 to retry boot, F2 for setup utility
and then a cursor would flash again, i also tried braking the circuit at this stage, but nothing has seemed to work.
Any help would be great.
Thanking you
driver
PS. Thanks to those who have already helped
Update: Never mind, my problem was that i was making the link with the paper clip but was not holding in the power button, instead i would just press it once. The secret for first timers is to make the link when laptop is off and then hold the power button in for at least 5 - 8 seconds.

Helpful site!!
I found a site with a sort of tutorial of how to short circuit the eeprom chip, it has a few pics which might point people in the right direction.

I followed the steps but i have a CPx not a CPi and the chip doesnt seem to be in the same location, does anyone know where the eprom chip is on a CPx?
just point me in the right direction please!!!

Haha! I did it!!! the chip was where u said it was. I put the whole thing back together without the case, then turned it on its side and shorted the chip with one hand while holding the power with the other and it worked.
now when it boots it says its in manufacturer mode press Fn-x to return to normal mode, should i do that or just leave it alone?
Thanx everyone!! :bounce:

You can press FN-X together and reset the laptop, but you will not have a service tag installed on the EEProm and will be unable to set a password of your own until you do. Did you get the DST file for a Floppy diskette? A USB 2.0 Floppy and cable is what I use with the D models, and is the required DOS Bootable.

After removing the keyboard, you should see an aluminum heat sink with a copper ban running in an "L" shaped pattern. Remove the two small copper screws and pull up the heat sink. That should reveal the CPU daughter boad. Remove the 3 screws holding down the daughter board and gently pry it up with a small screwdriver. You will see several surface mounted IC chips. The one just right of center is the chip you want to short. You may need a work magnifying glass to see it. The rest of what to do is on this forum.
