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. I believe I have found the schematics for this chip, but seeing the actual chip is obsolete I’m going off of an ROHS version that I think is the same. 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.

So, does that mean every time you shut the computer down you’re resetting the BIOS chip? Again, I need to go over the data sheet, it should tell me this info.

Also, I took a picture of the chip itself for ID purposes. Also, this laptop has NO BIOS battery but a larger surface dwtasheet cap, I don’t understand how the settings stay set if there is nothing there to keep power going to it. Below is the Device Reset information from the Data sheet: Did the thread i linked have more detailed info on pin shorting?

I have a A08 bios in datazheet 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.

So you have no way to boot separate media of any kind? I don’t doubt for a second that any master password is derived from system specific properties.

Specifically what is locked via pw? The Vcc drops to nothing well at least under the 2. Originally Posted by Peter9DO.

I only glanced at that thread but it was though folks would pass over their info and have a mpw given in response Maybe I don’t understand why these combos, from what the schematics shows, it really doesn’t make any sense to me.

Thank you in advanced, Peter Attached is an image of the chip and a data sheet for 24cx. Find More Posts by gilly The 24C02W6 IC has a device reset within it.
