Vel mihi ede potum vel mihi redde nummos meos! 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?

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.
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. daatasheet

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. Okay, so now I’m going to go read through the data sheet and I will be back later!

Last edited by heavymachines; at I don’t doubt for a second that any master password is derived from system specific properties. Last edited by Peter9DO; at I believe I have found the schematics for this chip, but seeing the actual chip is obsolete I’m going off of an ROHS version that I think is the same.
Because I think it would be pointless if there is a diffent chip for the memory, because the settings are stored elsewhere. Specifically what is locked via pw? Last edited by trebo; at 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.
I only glanced at that thread but it was though folks would pass over their info and have a mpw given in response Originally Posted by 2andrewd Thats a super cap which effectively IS the battery. The Vcc drops to nothing well at least under the 2.
I doubt this will work but here is your cmos battery location. Below is the Device Reset information from the Data sheet: I have a A08 bios in my dell Latitude, My Systems information says that, Dell is the bios manufacturer If thats any help.

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.

Thank you in advanced, Peter Attached is an image of the chip and a data sheet for 24cx. Nuneaton Warwickshire My Country: 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. What kind of laptop are we talking?
Yea, there dataaheet no CMOS battery on this one The time now is Thank you in advanced, Peter Attached is an image of the chip and a data sheet for 24cx Attached Images. Originally Posted by 2andrewd dstasheet through this thread. Min Vcc for this IC is 2.

If someone could please help me and just run through the process of shorting the chip to verify that I’m doing this all properly and to make sure I have done the right pin combination, I would be in debt to you! Okay, so after reviewing the datasheet which is the correct one dwtasheet I add and taking some readings.
Also, I took a picture of the chip itself for ID purposes.
