In one of the questions before (from October 2009) the question has been answered how to get an ACER Aspire 5102WLMI with 4GB of memory up and running beyond POST. I have exactly that problem, but don’t get it resolved despite your answer. I really don't know which PCB tracks have to be shortened and the 'jumper' J2 doesn't exist. There is a JP2, but that seems to be no jumper to me.
I have made a photograph of the PCB tracks under the DIMMs. Would you please be so kind to give me a clue what to do (referring to that picture)?
Thank you very much in advance!
