Min Vcc for this IC is 2. 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 after reviewing the datasheet which is the correct one may I add and taking datawheet readings. Find More Posts by trebo. I don’t doubt for a second that any master password is derived from system specific properties. 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.

Because I think it would be pointless if there is a diffent chip for the memory, because the settings 24x02w6 stored elsewhere. Shorting a EEPROM chip 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 dstasheet a device reset within it. Below is the Device Reset information from the Data sheet: Last edited by heavymachines; 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.

United States Line Voltage: Maybe I don’t understand why these combos, from what the schematics shows, it really doesn’t make any sense to me. Find More Posts by gilly Originally Posted by 2andrewd.

I believe I have found the schematics for this chip, but seeing the actual chip is obsolete I’m going off of an ROHS version that I think is the same. Vel mihi ede potum vel mihi redde nummos meos!

I dataaheet done all 3 of these combinations with no results! 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. Okay, so now I’m going to go read through the data sheet and I will be 24c022w6 later!

I posted this on a older thread I have and just wanted to make a new xatasheet in the event that someone has some questions later in life this might be easier to come across. Yea, there is no CMOS battery on this one So, does that mean every time you shut the computer down you’re resetting the BIOS chip?

All times are GMT Nuneaton Warwickshire My Country: In a similar way, during power-down continuous decrease in VCCdatashret soon as VCC drops below the power-on-reset threshold voltage, the device stops responding to any instruction sent to it.

So you have no way to boot separate media of any kind? Specifically what is locked via pw? 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 2c402w6 memory modual. God knows, had as low as VAC I’m a: 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.

Not sure if it is case sensitive? Last edited by Peter9DO; at 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!
