So, I recently acquired a Alienware 15 R1 (LA-B753P) as the guy told me it was completely dead, and I saw it as a fun project.
I have done every ordinary thing, such as resetting CMOS and leaving the RTC battery out for a while. It is completely dead, no light, nothing. The powersupply outputs 19.5V and the DC plug measures fine. I have inspected the board, and nothing seems to be obviously damaged, no burn marks, and no apparent water damage. The next step is to check for shorts, however, how would I go about doing that? I don't have a bench powersupply, so it is difficult for me to inject voltage and check with alcohol evaporation etc.
Anyone willing to give a bit of guidance?
