                  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...

                  Probook 450 G6 Blink 5 times - No boot - NEED HELP!
                  by BachPhi
                  • Issue:
                    Notebook blinks 5 times on power-up and does not boot.

                    Actions Taken:
                    • Tried multiple reset key combinations: V, B, Win, Win+V, Win+B.
                    • Removed and inspected all components on the mainboard (Part No. DA0X8JMB8E0).
                    • Replaced the RTC battery (CR2016W).
                    • Swapped in a different RAM module.
                    • Checked the BIOS chip (Winbond 25Q128JVSQ):
                      • Measured Vcc = 3V
                      • /CS signal stays high after power-on (no activity).

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