    BIOS rebuild requested for HP Pavilion Aero 13-be0003ca laptop
    by trepachka
    Hello, I have the following laptop:

    HP Pavilion Aero 13-be0003ca
    ProdID: 2L7M8UA#ABL
    S/N: 8CG150GPV6

    Motherboard information is below:

    HP Part# M52826-601
    448.ONE04.0011
    203016-1

    It needs BIOS repaired.

    I created a flash drive using HP firmware utility and then had it plugged into the computer. I did the standard WinLogo->B key->Power button press. A window appeared and immediately began flashing the bios using the flash drive.
    But I don't think it finished all the way. So, now when I attempt...

    Yamaha RX-479 PSU exploded
    by Satdude
    Hi, I have a Yamaha RX-497 receiver, and one day I came home to a burnt smell and the breaker was tripped. Upon opening the receiver, I saw extreme damage to the main power board. C254 was exploded, R261 was burnt, D255 was shorted, Q254 is open circuit, D261 (bridge rectifier) is also open, traces to IC252 (TC4013BP) are vaporized right off the board. Not sure about any other damage, I'll have to desolder the flip flop to test it. Also the transformer T251 is getting hot when plugged in. What could have caused such extreme damage just sitting plugged in? Only repair that was done in the past...

    Seasonic X660 not turning on when PC is in sleep mode
    by joekajoeka
    Hello,
    I have a Seasonic X660 from 2011 a very quiet and reliable PSU it worked great but in 2023 started that it wont turn on when the PC is sleeping, if I switch fast the power switch on the PSU than it would switch on and also the PC wakes up from the sleep.
    If the PC is shut down normally than also the PSU starts normally every time.
    (I checked the PSU on another PC with the same result for sure the PSU is faulty)
    Has somebody a clue what is wrong in the PSU? has somebody repaired this fault for this exact PSU? I would like to repair this PSU.
    Thank You!...

    TDK ZWS150BAF-12
    by Keshenatech1
    Does anyone have a schematic or parts list for a ZWS150BAF-12 12V power supply? I have a dead one and I've determined the surface mount diode on the back side of the board that connects from the center leg of Q3 to the + side of the 420V 60uf capacitors has a 3.5 ohm short. I'm not having much luck trying to identify the diode as the part number is not very legible. In the attached picture, it's the black rectangular diode in the center. There are some numbers on it but I can't even tell if it's right side up or upside down. The picture is from a 2nd good working unit which is more legible...

    Hi, my TV image started showing those lines and the image faded away, but sound is still coming from it, what could be the cause and is it fixable? I thought it could be the tcon board but I red on the internet that it could be a failing panel

    cisco poe switch PSU issue
    by madan1
    Hello everyone.
    I'm troubleshooting a cisco switch, which seems to have an issue with the PSU.
    The psu has the following power rails - +12v, -53.5V and +3.3V
    When connected to power, the +12 and -53.5 seem to work fine, but the +3.3 starts at ~3v and then goes down to ~0 (I guess this is the cap discharging). This happens both when the cable is connected and not to the switch board.
    Any ideas what might be causing this behavior?

    my Xiaomi Notebook Pro X laptop fans work like crazy for no reason
    by sda sad
    Hope this is the right place, someone can help me.
    My laptop started having a really strange problem....
    When I turn it on the fans start working at a crazy rate and with random breaks...
    They can work for say 10 seconds and stop for 2 seconds and then turn on again for 5 etc...
    And it's from 0 to 100%. I tried to install AIDA and did the processor chip test and the graphics did not exceed 70 degrees and the fans were not even close to working at the power they work randomly.

    The model of the computer:
    Xiaomi Notebook Pro X 15 OLED (A30)

    Lenovo legion y540 adapter pin id
    by TheOtherGuy
    So I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...

    Philips PSU (715G7350-P01-000-002S) behaving funny
    by hervou
    Hi all,

    I'm becoming crazy trying to fix the Philips TV of my old man (model 43PUS6201/12 - the TV, not my dad). I've read again and again discussions about this and similar TV models, on badcaps (thanks so much !). I see no other option than asking for your help.

    The symptom is simple : when I plug the power cord, the red "stand-by" LED does not light on anymore, and the TV powers-on neither with the remote control nor with the rear button. I guess at this point you immediately think at the 5V (or other voltage depending on the hardware) stand-by output......
