if that does not work, please let me know
Sorry about all that. No it doesn't work in Unlock setup or Admin password
can you remove your cmos battery
Yes, I tried that
If I knew what the chip number was I could short out the pins. I've done that before and it works.
i am checking
did you try this one
Hmmm, I've got it out but didn't see that chip. I'll look again.
I can't find it. I don't want to tie you up. I'll tear it apart a little more and see if I can find it. You have to short them out while you turn the power on so it shouldn't be too hard to find. Thank you I will give you a good rating so you get paid
you are welcome, if something goes wrong, please let me know
I will thanks
