Joshua_S 0 Report post Posted March 16, 2018 Hi forum, First time posting here, I have a dv6120us, motherboard part number 434723-001. A little while ago, the fan on my laptop started malfunctioning, it wouldn't turn on at all. Neither would the computer shut down from overheating. After taking the motherboard out, I discovered a blown transistor. I know how to change this, but I do not have the motherboard schematic with the information on this particular transistor PQ51( Have a further understanding of transistor and its functions and characteristics=>http://www.apogeeweb.net/article/72.html). Does anyone have the schematic that can give me the info I need to get the replacement? I would hate to replace the entire motherboard for a simple fix like this... Thanks Share this post Link to post Share on other sites
