Hi, all,

I recently got a Biostar MB-1333/40PMB that was sold as "damaged" as a project to see if I could rescue it after some moderate battery damage. I've done a fair amount of scraping and toning-out of things, and it looks like while most of the damage is superficial, there are some casualties where the battery's electrolyte crawled up the legs of some components.

Would anyone happen to have one of these boards in good condition, and if so, can you tell me the values of some of the components so I can replace them?

When describing component locations, I'm treating the keyboard socket as the "upper left" corner.

Specifically, I would need to know these component values:

  • C1 (upper left corner of board, above power socket
  • C35 (just below battery socket)
  • D7 thru D10 (I'm assuming these are 1n4148s or equivalent, but I'd like to be sure if someone knows)
  • Q1 and Q2 (I think Q1 is an MPS3904, while Q2 is a MPS3908, but the markings are very badly faded)

If anyone happens to be able to help me with this, I'd be very appreciative.

I just acquired one do you still need values?
