I know about the Antron test-head……………. Are you sure your 24RF08 has got 16 pins?
Still got the 8 pins as shown in the diagram and curcuits. IBM wanted Euros to fix it, its only worth half that amount in good condition! What he 24rvc8 not tell you is that this chip is also produced in the pin 24rc8 and is present in many models of thinkpad!! You have to keep on searching. The zeners and resistors can be found in scrap electronics, but they are rather cheap so i would not bother.
Leave these wires unconnected and make them ready by peeling off the insulation. I can see under the mousepad a big chip with intel, but there is one more little board under the mainboard next to the RAMs.

Also, what model is your TP? I ordered all my parts from mouser. This is the folder address… C: A31 is having the 8 pin chip! Touched the probe on Vcc then quickly ran patch. All the other information including hte serial number model number etc is visible, but no password. Thanks again for a wonderful Web Site! I would like to mail you a copy of my bin file. I have a A20m but I cant find the atmel chip anywhere. Here is a simplified schematic for those unfamilliar with the above symbols:.
I just had the same problem. The eeprom is located on the bottom of the motherboard near the ram expansion connector but cannot be reached without taking the laptop apart. No, create an account now. I know the guys there and they have this solution since last year avaialble. If you could provide any more information on this i would greatly appreciate it. Just wonder whether I got the right components: Did u find the correct chip?

The supervisor password SVP is stored also into this litle chip. But do know where the chip is located on the mother board? No problem, on this page i will show you how to recover your old password.
I have just over 21 years experience in electronics engineering and microprocessor based systems. At any rate I was able to assign a wtmel hard drive password and delete the sys pass from my T No chip on IBM A21m. Is it a common to need more than one attempt to get a successful read? I used 3 old tiny HP probes to clamp on at,el tiny leads. I did the same wich u mention in the diagram. Then I tried R24C01 and it worked the first time. No need to disassemble the laptop.
Beats buying a new fine tip soldering iron.
