Hello all,

I know this has been covered extensively in other threads but...

Ive tried searching for this to no avail.

Which pins do you short together? I cant seem to find this info. I know which chip, but which of the pins do i short?

Thanks

Lee

Hi Leesh and welcome to the TS Forum


From what people have told me (via feedback from the site) the usual favourite is pin 3 and 5, short whilst powering on from 1 to 4 seconds or short with the battery out and the AC removed and press the power button repeatedly.

To really be sure you need to be methodical, try various pin configurations and keep a note of what you have tried..BUT DONT SHORT PIN 8.

Happy shorting

Regards

thanks i'll have a go.....

yay done it.

Thanks mate. It wasnt such a hard job really. Not with the service instructions from the dell site. They tell you exactly how to take the machine apart.

pins 3 and 5 worked. Switch on, then short. Would turn on with the pins shorted.

This was done with out the keyboard connector plugged in and the palm rest connections.. er un connected.

I know this is an old thread, but I am bumping it as I have a D400 with the same issue, and shorting the 3/5 pins did diddly squat. Is there any more detail that anyone could add to when the pins should be shorted, when to expect results etc? Many thanks to all.

just to let you guys know i sorted out my problem but thanks for no help plus i got own thing runnin now if you hand were always there enjoy all

sorry missed it out

Hello guys, I'm new here and the reason I jointed the site is because I have a Dell Latitude D531 laptop with: SERVICE TAG 8HZ8LF1-595B. Now, I have almost read all the posts on here, i have try all the password removal software and master password Generators but none of those work. I can't boot from anything till i reset the bios password. I open my laptop but I could not locate the EEPROM 24c02 chip. So, I like to know if anyone here has been able to unlock any dell with service tag ending on 595B or anyone knows if there is a EEPROM chip that can be reset and where is located at. I would really appreciated.
