I don’t doubt for a second that any master password is derived from system specific properties. In a similar way, during power-down continuous decrease in VCCas soon as VCC drops below the power-on-reset threshold voltage, the device stops responding to any instruction sent to it. Again, I need to go over the data sheet, it should tell me this info.
Also, this laptop has NO BIOS battery but a larger surface mounted cap, I don’t understand how the settings stay set if there is nothing there to keep power going to it.
Last edited by trebo; at I only glanced at that thread but it was though folks would pass over their info and have a mpw given in response Below is the Device Reset information from the Data sheet: Pin 8 Vcc, Pin 4 is ground Vss If I was going to short it I would connect Pin 8 to Pin 4, if I did this while the computer was on it should give it a short, but will it damage the chip?

I doubt this satasheet work but here is your cmos battery location. Originally Posted by 2andrewd read through this thread.

Not sure if it is case sensitive? Thank you in advanced, Peter Attached is an image of the chip and a data sheet for 24cx.

What kind of laptop are we talking? Thank you for all datashedt help that everyone has provided thus far! Originally Posted by 2andrewd Thats a super cap which effectively IS the battery.

Because I think it would be pointless if there is a diffent chip for the memory, because the dataxheet are stored elsewhere. Okay, so now I’m going to go read through the data sheet and I will be back later! I posted this on a older thread I have and just wanted to make a new thread in the event that someone has some questions later in life this might be easier to come across. The 24C02W6 IC has a device reset within it.
Okay, so after reviewing the datasheet which is the datwsheet one may I add and taking some readings.
