    Hello.
    I have a problem with the power system in my HP. The problem is that I have burned one of my companions and I can not read what is the layout. This system is located under the umtsa card sticker.

    A colleague talks about the rights to the forum, where you will find a diagram. The photo that has been pasted is of poor quality. No one will guess which item you have damaged on the disc.

    I do not know what's going on with this layout, I may have misspelled the question whether I will replace the power system exactly if it will work because apparently this system is responsible for the entire power supply and how the nickel will burn in a chance to start working

    Does any of you know what is the difference between LM393M and LM393 (without M at the end)?
    There is still LM393N on the market, but this one is for the rebated montage.
    And in this case you need an SMD element for surface montage.

    Both will fit.

    Edit.
    Insert the fragment of the scheme you asked for.

    Zanes started the topic, which happened to me only when it came out completely in LM393M. The blame was the polarity of the power plug.
    I sold a new art in its place so much that I do not have a pad under the first leg and I do not know where to solder it, maybe someone also had this problem and successfully solved it, I put a picture of my current situation.

    Do I see correctly that the pad was removed and connected by a green path with solder fields not used under resistors?

    Look for an SMD system with 128 legs

Topic summary

The discussion revolves around a power system issue in an HP 6910p laptop, where a component has burned out, making it difficult for the user to identify the layout beneath the UMTS card sticker. Participants suggest searching for the motherboard schematic online and request clearer images of the damaged area for better identification. The user shares multiple photos, but the quality is criticized, leading to requests for more focused images and specific component designations. The burned component is identified as PU25 - LM393M, with discussions on its compatibility with other variants like LM393 and LM393N. There are also inquiries about the KBC1070 system and its location on the motherboard.
