Okay, that is the right chip. Try the after Power On shorting. Read this standard blurb of mineDODONI said:it is ATMEL 436 24C04N S127

The chip on this board requires shorting/grounding of pin 5 or 6 after Power On with a delay time of from 1-6 seconds. Pin 4 on the Chip is the ground for the paper clip method, but the mod.shorter in the picture is easier to control and use for the after Power On shorting or grounding. The clip is fastened to any grounded screw or screw hole in the board and the straight pin point touched to pin 5 or 6 at the proper time. I no longer use the paper clip, but use this mod. shorter exclusively.
If you short/ground and the laptop shuts down, you were early, if it continues to boot, hold the short and see what results. If the grey password screen comes up again, you were late with the short, so start again. If you get the Manufacturing Mode screen, continue holding the short in place for another minute to completely drain the EEProm Chip of its Service Tag and passwords. This latter result I call the "Sweet Spot". The EEProm chip loads the Service Tag and Passwords into the BIOS chip on each boot and you are trying to run them into ground instead. You are trying to short/ground after the boot is committed, but before the Bios Chip Loading has started(a very brief period) and then hold the short until the chip is cleared completely.
I hope this helps you
