    Lenovo LOQ 15APH8 - no post, power button blinks steadily

    Model: Lenovo LOQ 15APH8
    Serial: MP2LMAV
    Board: ILG50 LA-M811P Rev 1A

    This device came in for no POST/boot. It is drawing 2a when connected to the charger. Pressing the power button, I get keyboard backlight, then the power button blinks continuously, 1 second on , 1 second off. I flashed a brand new(unmodified) BIOS from Lenovo's website but that did not do anything. I was told by someone here, that despite missing the DMI blocks, if this were a BIOS issue, it should still boot after replacing the BIOS. There is only .2 ohms resistance on the GPU coils. I have been told here that extremely low resistance is not uncommon.

    What are my next steps?

    Thanks!

      To share a overview about the whole board situation (voltages and resistances) and Not only of those areas what you think might be important.

      The key in such cases to share as much informations as possible, since the given information obviously doesn't lead to the solution.

          HP Envy 13-BA1565na with intermittent power button
          by themosttogain
          Hope someone can give me some suggestions on this because i'm at my wits end with it...

          I have an Envy 13-BA1565na here with an Intel Core i7 i7-1165G7 CPU (board is a LA-J475P Rev 1.0) which has an intermittent power button issue. The power button is integrated into the keyboard, and I have ruled out the keyboard, BIOS and battery as being the issue.

          Basically, on mains power, the power button works fairly well. The first time you come to it after leving it sitting (either on charge or not on charge), it might take 2 or 3 presses of the button, but then the laptop boots...
