    HP Victus 15-fb0104nw not turning on, charging led blinks 3 times

    Hi,
    I'm working on a HP Victus that is not turning on. When power button pressed it only blinks 3 times with charging led. I have checked input mosfets and they are fine. Also all coils are fine too. Battery was empty but I charged it with my lab PSU and laptop started on batery but is not charging. When battery is disconected and only PSU connected it takes 0 current and not starting. What can be the reason?

      Which charger IC?

      Review voltage to ground of:

      ACDET
      ACDRV ; assuming TI charger IC
      REGN

              Samsung DM32D – Red LED blinks 5 times, won’t start (possible mainboard issue)
              by Nairolf
              Hello,

              I have a Samsung DM32D display.
              When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.

              Here’s what I have tried so far:
              1. Disconnected the cable between the mainboard and the power supply → the backlight turns on.
              2. Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
              3. Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.

              From these tests, I suspect the problem might be on the mainboard. Could anyone...

              Lenovo T14 Gen 2 Type 20XK Model 20XK0069US Odd Charging Issues
              by coasterghost
              For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

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

              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.

              HP Probook 470 G4 - Power and Charging Problem
              by Scoff
              Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
              Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...
