    HP 14-006la Who know about this component?

    Hello partners. Kind regards.
    I would like to know if anyone has knowledge of this motherboard.
    HP 14-006la
    I have been reviewing, and I found that these two pieces that appear in the circuit mark continuity, but I don't know what they are and if it is normal for them to mark like this. They do not have any numbering or identification on them or on the plate, only the one that appears higher in the image has the word "D6046" near it, but I do not know if it refers to that piece or the one that is higher than it, and If it is a diode, what type of diode is it, and what is its value?

    I wanted to know if someone can give me a guide regarding this part of the circuit, since it has been impossible for me to find that diagram so far, and all those that I have consulted about the HP brand with similar sources, do not show me those parts or their value. Already one of the colleagues sent me a schematic, but since it is not the same, those pieces do not know what they are and what they do in the circuit.
    I do not know if it is normal that at point b of the connection it marks continuity with respect to the plate's ground, or is it that there is a short circuit at that point. When removing these two pieces, the voltage in the U6000 that is more to the left below, starts to work and 25 volts reach the transistor Q6010 that is above, and there is voltage at its ends, but I need to know if the pieces that Take out are low value resistors or are zener diodes or normal shorted diodes, or other type of component. Before removing these two pieces, there was no voltage on the gate of the Q6010, and when removing it if there is the 25 volts that turns it on, but I imagine that when putting the pieces back, I suspect that more is going to be the one that says "D6046" The voltage is going to go, it seems that there is a short circuit, but the problem is that I do not know what those parts are and if their operation is to let the voltage pass through that area.
    Any help that someone can give me?
    Thanks...

    Fixing the Charge Circuit of the Batteries of the DC Motor
    by Astonished
    Hi friends of electronics

    What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.

    The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.

    Please help me fix this circuit.

    Short Circuit tester
    by Tarot Superstars
    Hello.
    I have seen a short circuit tester made with 3 * 9V batteries, a voltage limiter component and a resistor connected to the probes of a multimeter.
    The theory is that the meter becomes sensitive enough to read very low resistances and the lowest resistance to ground on a circuit is likely to be a short circuit in that area.

    MSI B250 Gaming M3 Short circuit in CPU power supply circuit
    by M1NEBLANK SHOW
    Hello. MSI B250 Gaming M3 board, short-circuit on the power supply. Found a problematic mosfet VQ1
    (N-PK616BA_PDFN8-HF) soldered it out - short circuit is gone. I replaced VQ1 + VQ5 (N-PK632BA_PDFN8-HF). VQ1 was replaced with PK618. After starting attempt VQ1 is lit again. What can be the problem? In the driver?

    Viper22A 5VSB circuit
    by прямо
    So I have a cheap non working ATX PSU that I was learning to repair a decade ago. At the time, it blew the main fuse, bridger rectifier, NTC, and primary 9A 900V MOSFET. Replaced all except the MOSFET. 5VSB came back online. Then I poked around in it so much, measuring components one by one to a point I accidentally made the 5VSB circuit primary side went bang. Blown the AP8022 (Viper22A) PWM chip, along with a low resistance resistor and the PC817 opto isolator. I replaced them all.

    In the process of poking around, I also lost a zener diode that stabilize the voltage coming from...

    Is ESR value different between on Circuit and off Circuit?
    by chth96
    A few days ago, I purchased MESR-100 ESR meter, and When I measured a SMD capacitor on circuit,MESR-100 showed ESR value of 30, But I managed to desolder this SMD capacitor from circuit and measured it then MESR-100 showed ESR value of 18.
    I also measured it with Mega328 Transistor Tester, and It showed ESR value of 17.
    Is my MESR-100 defective, if the ESR value is different between on Circuit and off Circuit?
