This is a bit of a long shot, but I recently picked up a damaged Dell X300.

Someone had attempted to remove the security password by removing the eerom. Without success I might add, they have however screwed up the network card. Confused

I can boot from USB, and will therefore be able to sort out any other issues.

What they have removed is the chip at location U527 and since I don't have a similar board to compare with, I wondered if anyone could confirm this is a 24LC04 as I suspect, or have they removed something completely different.

Any help here would be much appreciated.

Regards.


Very Happy

I don't have a board here, but if that IC is a 8 pin SOIC, then is a 24C04 more than sure. You have to mount another one, then use asset.com to stamp a new(or old) service tag in it.

Thanks for that, and although I'm 99% sure it is a 24C04, (it is an 8 pin SOIC) I'd like to be certain. BTW the location might be U517 rather than U527, the screen printing is a little unclear.

I'll take another look and make sure only the active pins actually go anywhere, and if I am feeling brave (or foolhardy) I will probably pop a 24C04 on the board and see what happens. Since the LT didn't cost much I wont be too upset if there is a puff of irreversible smoke. Confused

Then don't worry about it, do it..

Just to remind you that pin4 is the GND and pin8 is Vcc, if that is of any use. Laughing

...and I have the datasheet for the 24C04, only trouble is I can never get the smoke back in to the chips once it comes out. Twisted Evil
