G'day
my m2000 preario will not charge from the charger or power up but works fine with the battery untill it runs out. I added some RAM and screwdriver slipped and shorted something out as it sparked.
Tks

You may have damaged a power controller chip like the MAX1999 or another.
If you had no problems before replacing the RAM I would say that you shorted a MOSFET and it will need to be replaced.
Or another part. That cannot be diagnosed well via forums.
Typically an 8-pin chip. like 4407/4411/4431 or 48xx series. Cannot tell which one, because I don't know where the screwdriver slipped nor can I see & test the board.
good luck
