Last edited by Peter9DO; at Thank you for all the help that everyone has provided thus far!

Not sure if it is case sensitive? I have done all 3 of these combinations with no results! God knows, had as low as VAC I’m a: Maybe I don’t understand why these combos, from what the schematics shows, it really doesn’t make any sense to me.

Also, I took a picture of the chip itself for ID purposes. Okay, so now I’m going to go read through the data sheet and I will be back later!

I don’t doubt for a second that any master password is derived from system specific properties. Originally Posted by ReverendJones. Vel mihi ede potum vel mihi redde nummos meos! There is a schematic of a circuit consisting of several zener diodes and a couple other components that allowed me to pull the bios pw off of a T41 thinkpad but i believe the chip was an Atmel.

I posted this on a older thread Dataseet have and just wanted to make a dagasheet thread in the event 24d02w6 someone has some questions later in life this might be easier to come across.

At power-up continuous rise of VCCthe device does not respond to any instruction until VCC reaches the power-on-reset threshold voltage this threshold is lower than the minimum VCC operating voltage defined in Table 6, Table 7 and Table 8.

Yea, there is no CMOS battery on this one Page 1 of 2. Find More Datasneet by 2andrewd. Originally Posted by heavymachines.

I only glanced at that thread but it was though folks would pass over their info and have a mpw given in response The 24C02W6 IC has a device reset within it. Thats a super cap which effectively IS the battery. Well, I was working on the laptop and retracing my steps, make sure I was doing things right seeing that I have worked on this so long ago I don’t remember what I had completed seeing my notes on this one were not very complete, I’m sure out of pure frustration.

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.

Find More Posts by vinceroger What kind of laptop are we talking? Did the thread i linked have more detailed info on pin shorting? Thank you in advanced, Peter Attached is an image of the chip and a data sheet for 24cx.

Because I think it would be pointless if there is a diffent chip for the memory, because the settings are stored elsewhere. Just to let you know the way I’m doing it, I’m attaching a wire to whatever pin combo and then turning the computer on. Min Vcc for this IC is 2.

Originally Posted by 2andrewd. I’m running out options to try with no luck thus far I’m debating swaping out the chip itself, but I’m not sure if the 24c0w6 IC has built in memory or is it linked to a memory modual.

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.
