Posted March 16 · Report post 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
Posted March 27 · Report post Can you read the part number from the transistor? If so then type it into digikey.com and go from there... Jack. Share this post Link to post Share on other sites
