    Re: I need a schematic for Lenovo IdeaPad GS454/GS554/GV450/GV550



    thank you very much for the scheme

    but I need to ask for help it is the first edp screen I see and I don't know why the backlight does not turn on

    I already checked the schematic but I can't find the fault, the only weird thing is on pin 1 and 2 it only gives me 7.5 volt
    DISPOFF is not physically on the board
    INVT_PWM is missing two resistors that do not come as in the schematic I am lost

    I am looking for drivers for LATECH DLCJ-007 tablet

    In Mexico the government gave away these computers called LATECH DLCJ-007, my problem is that they come with windows 10 x86 ver.1601.

    So a few days ago Microsoft sent a forced update but when I finished the update I was left without a touch screen, without wifi, and without many other functions.

    that's why I'm looking for an image of the original system, or failing that, the drivers to install

    I hope you can help me

    and sorry for the google translation, i don't speak english

    started a topic help, i need the schematic n61pc-m2s
    in BIOS & Schematic Requests!

    help, i need the schematic n61pc-m2s

    hello I need help, I want to find the schematic of a motherboard n61pc-m2s is a biostar board with the mcp6pb m2 + model see: 6.3.
    in the forum there is only the bios
    What happened to me is that a capacitor exploded while the machine was on, the machine turned off, at first I thought that by changing the damaged capacitor for a new one the pc would turn on but it was not.
    I want to try to revive it
    What worries me the most is that the capacitor that exploded is next to the bios battery

    no, it didn't work.
    remove the lan chip and continue with the same.
    I suspect the instant on, but I still can't find the schematic of my board, there is one in the forum but it is for amd and it does not match my board...

    Dell Inspiron 14z-n411z turns on by itself when trying to turn it off

    first apology for the bad english, it is google translator.

    The problem with the machine is that when trying to turn off the machine it turns off for about three seconds and then it turns on by itself
    The only way to turn off the equipment and to keep it if it is to force the shutdown by keeping the power button pressed until it is turned off.

    I already discarded a software problem when testing it with several linux distributions in addition to windows 7, 8.1, and 10 in all it does the same

    I was suspicious of the power button, so I bought a...
