    HP Elitebook 845 G8 dead, only caps lock flashing 7 times. Charging light always on

    Hello everyone.

    This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
    Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
    Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
    I tried long pressing on the power button, after several seconds it would go off then when the button is released the power button light would flash for half a second but the charging light would still on - this light goes directly on when power source is connected - even the battery!.
    Before completely going dead, sometimes when trying to force it to power on, only the fan would spin fast without anything on the screen or keyboard light.
    I opened it, connected the charger and I could feel one coil (I guess it is one - 1R0 2127) would get a bit hot. (not happening anymore)
    I have basic knowledge on electronics but I can learn fast.
    I have a multimeter. a soldering iron...
    Anyone can help troubleshoot this issue? I can work anymore since this is my main machine.
    Please feel free to ask for more info and I'll provide them.

    Best regards

    Which charger IC is on board? Hunt for this part and share the top side markings. It may be the popular BQ charger chips by Texas Instruments. Square in shape with black body. Post pics.

      HP Elitebook 850 G8 CAPS lock flashes 7 times and charging light always on
      by esqmooo
      Hi,
      I'm facing this issue since this morning. When I try to power it on, the CAPS lock light flashes 7 times (or 6 if not counting the first one when the power button is pressed). The charging light is always on as if the laptop was connected to the charger. The issues started gradually where it would flash the light but after trying multiple time it would power on. I tried to open it and I noticed one coil "1R0 2127" gets hot when the charger is connected. Note: the charging light directly comes on when the battery is connected or the charger is connected.

      Dead LA-H323P (no light) - HP 15-DW
      by Patan
      Need help here...
      I'm new on the forum and I'm not professional in electronics so i ask sorry in advance for eventual errors...
      As title says, i have a LA-H323P dead.

      Now, little background.
      The computer was working fine, just seems that the cable of screen was dying because it had the classic color problem, sometimes green, sometimes violet, sometimes perfect, but anyway working.
      When i opened it the battery was so fat that was seriously near to explode.​
      So i removed the battery... and turned on the notebook... that was, again, working perfectly fine....
