    820-00165 No image, Chime, Minimal USB Activity

    Gotcha Shows on page 12 of my schematic, sorry for the confusion All seems good there. All rails are present, and output of the 1v05 rails measure between 1.045 and 1.052v Update: found R6114 to be measuring at 100k, rather than 25. Replaced, but issue persists. Checked all others once more...

    820-00165 No image, Chime, Minimal USB Activity

    Laptop suddenly died, no history of liquid or drop. Looks brand new All SPI Termination resistors and traces test good Voltages on page 11 being the list of rails / signals under "CPU New Properties"?

    820-00165 No image, Chime, Minimal USB Activity

    I have an 820-00165 board here with no chime USB flashes for half a second when first plugged in, no activity after that All CPU power rails measure normal, and CPU gets warm PLT_Reset_L is 3.3v PLT_RST_BUF_L is 2.8V Tried swapping a known good BIOS chip onto board, no change. Original has...

    820-00165 Not Detecting SSD

    All rails going IN to the connector measure .432 on both boards. I used the same SSD and another working 00165 board The rails leaving the connector are .550 on the bad board, but .385 on the good board (red probe on ground for both)

    820-00165 Not Detecting SSD

    Thank you! SSD_BOOT_R is 0v, but the only resistor on that line (R3701) is "No Stuff". Compared to donor board, it's not there either. I don't have a functional board to compare to unfortunately SSD_SR_EN_L shows 2.8v. Resistor shows 100k on schematic, but measures 60k. Same on donor board...

    820-00165 Not Detecting SSD

    Firstly, I think it's important to mention I have very limited board repair knowledge. I've done a few basic repairs, but never something as involved as this I'm working on an 820-00165 board that will not detect an SSD. Used a known good SSD and it doesn't show up in boot menu or DU (Internet...
