    my 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)

    Acer Swift 5 (SF514-52T) reboot loop mistery
    by nocnoc
    Hi all,

    I'm quite new to this and trying to learn by help a friend with his SF514-52T that stopped booting after battery was replaced. I suspected the battery was bad but the problem persisted when putting back the original one (which is was still working although with reduced capacity).

    When pressing the power-on button the symptoms are:
    - Keyboard backlight and blue power LED turn on for about 5-7 seconds, and then flash off-on in ~3 seconds cycles (reboot loop).
    - Display does not seem to turn on, although it sometimes seems to flash in between reboots....

    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...

    How to replace SMD blue Led with conventional red LED?
    by cap__
    "I heard that a blue LED has different voltage values than green and red ones. Green and red ones are easily replaceable, but how do I do that with the blue one?"

    "I have to use the blue one, because green means fully charged and blue means charging."

    Is it safe to power up ASUS ROG G14 without TPS25810?
    by MicroSMD Lab
    Hi, I'm working on an ASUS ROG G14, GA410QEC board. U1203 (TPS25810 but the schematic has it as SN1507044RVCR1) has shorted the +5VSUS rail. Is it safe to power up to test and subsequently use the laptop until I receive the replacement part?

    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...
