3/3/2024 0 Comments Dell pa 10 or pa 12 driversGiven the fact that we know that we are dealing with a switching mode power supply (SMPS), we will go from input side to the output side: Now that we have the power supply opened (consider any electronic device), we have to identify the main functional blocks and the type of electronic components. internet connection for electronic components data sheet electronic meter able to measure continuity of printed circuit board (PCB) traces So here is a little tutorial of reverse engineering combined with a short guide on how to tackle almost any electronic product you want to modify in case you have no schematic on hand (or if you want to fix it if it is defective). ![]() I searched the Internet for advises on how to modify such power supply, I found nothing about this particular type (PA-10 family from Dell). ![]() Unfortunately it was delivering a fixed 19.5 Volt, but a good amount of current (4.62 Amps). Fortunately I found a genuine Dell power supply for laptops, it was in good condition and was very cheap. I have a HobbyKing Turnigy Accucel Lithium charger ( link) and I needed to feed it with maximum 17 Volt DC. ![]() Warning: following project is dealing with voltages which are dangerous for human life (110 - 240 Vac)! Please be very careful and start this project only if you have working experience with such dangerous high voltages!
