Is there any hope for this laptop? I have tried every set of chips I can find with no luck.
Anyone have a good working set they could share please.

Sorry about that, After a bit of messing around I got this model to read at 3.3v and all seems to be ok.
Could you remove the password please, I did look at the 36010 to 36CE0 it starts off ok but at the 36CE0
it was all 00 00 00 anyway so was not sure of myself., Thanks mate.

I just got all these motherboards working Maxpower3.
I had to walk away from these for 2 weeks and have a break from them.
Turns out it was the programmer I was using, I fixed the svod by replacing the usb socket on it
I was getting problems with the svod for a wile now. All fixed.
Thanks so much for all your help mate.Leave a comment:

Thanks mate for giving it a go, it didn't work I done it 4 or 5 times it says to connect it for about 20 seconds on all the videos I have seen.
I took the battery out before I started. I will give this another go tomorrow mate. Thank you.Leave a comment:

Question please I don't have this laptop, I have a friend asking me if absolute persistence can be removed from this model?
there is no password on the bios but absolute persistence is active. I don't have the S:N.
Is it easy to fix? He seems to think not so I thought I would asked first. Thanks.Leave a comment:
