Hi everyone!
Nice forum, great help.
I've been searching for ways to fix my T20 (PIII 650, 2647-A2G), which has been showing the typical 0175 + POST error after startup.
I have no password, just this error and if I leave the notebook on for about 20 minutes, the screen goes blank and the leds go crazy.
I've read many pages here + Raymond's awesome tutorials, so now I have just a few questions I'm not sure about.

1) I'm still not sure which interface I should build (simple or driven), but if I do build the driven one, I'm not sure where I can find the MAX232 IC. My local electronics company has this: "SP232ACN-L ... RS232 SOIC16, possible replacement for MAX232CSE". Will this work? Costs 1 USD.

2) Would anyone be able to explain or have pictures of where the EEPROM is on the mainboard. I can take pics once I take the notebook apart so someone can point at it.

Thanks for your help!

1. It works.

2. No need to take it apart, the eeprom is located near the memory slots, if you follow the tutorial.

In my opinion, this laptop has a faulty DC/DC converter. Is it worth to fix the CRC only if you fix the mainboards power controllers, or the errors will ocur again.
