The 1525 uses a eeprom type chip. Removing the power via the Mitsu CR2032 button cell will do nothing to reset the bios password. Believe me I have been there done that. I am sure you can jump the cmos on the motherboard but have yet to find a soul that knew the chips location and/or which pin's to jump. I believe I've located the chip and some transistors located left of the battery. But I have no clue which to jump. I hope this can be done! This Inspiron 1525 is a Bi*&%. Any one with labeled schematics of this board could possibly help. I have the board info for all to see its as follows:
Intel ds2 48.4W002.031 not sure if this even cross references with intel being a Dell. Other option would be to know a L2 dell tec, read the numbers then their generator will cough up a bios admin password... "Anyone with that algorythm or the generator already compiled"? I'll Buy It!!!!! lol
Any way If I can help anyone or likewise just shout! l8ter all!
