                  Can you tell me how to check those signals? Do I need an oscillator scope?

                      Yes, you need an oscilloscope to check most of this signals. you can circumvent this with other instruments, like a signal tracer and a good voltmeter, but it is more difficult and won´t have the same results.

                          I knew it. Our first one is really damaged. I guess it's time to buy a new one. Thanks.

                          EDITED:

                          Can I use this one? Or this?

                              HP ProBook 445 G8 Battery not charging
                              by Julian Bailey
                              Hi all

                              We have in a HP ProBook 445 G8 laptop with AMD Ryzen 7 CPU. When power is connected the power LED light blinks 5 times then stops. Normally HP laptops will blink this LED 10 times as it does a self test when the AC adaptor is inserted. So there must be some sort of short somewhere.

                              The battery doesn't charge, and is erratic on the MM voltage. Bench PSU LED pulsates when the battery is connected also. So the fault must be on the charging circuit?

                              I have gone around the board with a MM and cant find anything

                              Windows shows the battery fine,...

                              since i couldn't find schematic or boardview for this model (LA-K062P), i use closest board model found here https://www.badcaps.net/forum/troubl...-and-boardview

                              the schematic share same marking for each component, using same PD-Controller, same BQ25710, the only different is the battery cell used. LA-K061P uses 3S battery while LA-K062P use 4S battery per schematic.
                              what i've done:

                              Hello everyone

                              I have been working on this laptop mentioned in the title, it initially had a shorted capacitor. After I replaced it, the thing started working again, but there is still another problem. The laptop was running off a charger, the battery was reporting 96% charge... but when I unplugged the charger, the laptop died. I've measured the battery voltage - 0V. I think it is locked. (Screenshot from batterymon, below).

                              I've ordered a new 3rd-party battery, but I think there's something wrong with it too - the laptop boots, but the battery isn't charging. Also,...

                              This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
                              The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
                              I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
                              And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)

                              Hi everyone,

                              I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.

                              Some history:

                              Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.

                              As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)

                              Now, with a new battery the system will start up and run off...
