MICROPHONE CONNECTOR (Front View) 7654321 DC 8 V, 100 mA max. The schematics would help as they would show what the component connects to which would help in knowing what it did and you could test the components further on in the output circuit path of the transistor to see if they're OK or not.Ĭomponents burning out are due to excess current flow, so either the component itself failed which can happen or other components have failed and this altered the circuit characteristics or there is another introduced problem such as water entering or someone checking with the power still connected and not being careful and creating circuit paths that weren't meant to be there in the first place. 3 MB schematic diagrams, printed circuit board views, and align-ment procedures contained. Looks like you may be in luck with more info from this link at least as to what the component is but maybe not why it failedĪlso it appears that you're not the only one to have this problem with the motherboard. Designation Q means that it is a transistor of some type. It's not C2503 that is fried it is Q2501 that is the faulty component. If you find the schematic (or the board number) and you need more help, post back here
#BOARD VIEW SCHEMATICS FULL#
When you have found the board number search online for (insert motherboard full board number information) schematic to hopefully get results.
#BOARD VIEW SCHEMATICS HOW TO#
Apologies if you know how to do this already You don't have to remove it but this should be helpful in gaining access to it to find the board number. Go to p.36 to view the necessary pre-requiste steps and then the procedure to remove/replace the systemboard. Here's the maintenance and service guide for the laptop, taken from this webpage. What is the motherboard's board number? The board number is printed on the motherboard itself. The number that you have been given is the HP part number for the motherboard, not the board number and searching online using this part number or the laptop model number gives no results for the schematics.
#BOARD VIEW SCHEMATICS SERIES#
You can view both sides of the board, pan and zoom, identify parts, trace signal paths and even list the manufacturer part number. Each has their own commands and options but generally they operate in the same way. I should note that I've seen several different, incompatible, board view programs using. You want to see part numbers on the board? Use the View, Show/Hide Part Name (or hit ALT-P) option and ALL of the parts on the board will have their names listed right next to the rectangles. That should be a via where the signal passes from one side of the board to the opposite. Those are the places where the smb_data signal is routed. Click the FIND button and you should see several items now displayed in red. This allows you to enter up to three signal paths and they will be shown as the related colors. There's two other lines that you can also specify that will be in GREEN or ORANGE. Use the Find/Find Net (By Net Name) command and enter smb_data in the first line (caps not sensitive). Why "U42"? That's the part name used in the schematic.
Open the file and use the Find/Find Component Part (or hotkey D) to enter U42. An example would be one system using Intel graphics, versus another that uses ATI. BDV file matches the schematic sometimes there's different motherboards used in the same model.
The board view program is used with the associated schematic diagram as the part numbers and signal names are embedded into the. From left to right:Īll of these actions should all be self-explanatory. If there's a hotkey associated with the action, it's also displayed.
In any event, hovering over the icons under the menu line will tell you what they do. To prevent that, simply work on a copy of the original file. From there, about the only thing that can go wrong is that you overwrite, if the program allows it, the data file. I don't see any connections, any part-numbers, any text, any indication what a particular rectangle might be.ĭouble-clicking on a dot marks it with a random(?) number, no idea where to go from there.Have you not thought about exploring what the various menu options are? If you can see the board view, then you at least know how to open a file. RealBlackStuff wrote:All that those boardviews show are rectangles and dots, no matter how big you try to make them.
