Did you try replacing your 74HC32?
Not yet. I have the components but haven't got the time to make the replacements (I have never replaced smd components so it doesn't help)
First I'll try the 74HC32 and then the back up RAMs.
Another point is that, out of the 3 mv1c that I have, the 2 in which I added the unibios (with the neobiosmasta) are the ones that drain faster the battery. Will try to find if it is related.
