    Acer Nitro 5 AN515-55-55M1 [GH51G mb] powers on, no vcc_core
    by malogro
    Hello all,

    I'm stumped on this guy, so wanted to see if anyone has any further ideas:

    Intro:

    This is an Acer Nitro 5 AN515-55-55M1 with unknown prior history (bought "as-is" on eBay). It charges the battery and powers on from both AC adapter and battery, so I think this rules out main power issues.

    Upon attempt to boot, it will "reboot" (meaning powers down and then powers on again) only once, and then stays stuck in a status of lights on / no post / no monitor. Powering on with fn+esc maxes out the fans on first boot attempt,...

    ASUS B5402CEA – Laptop powers on for a few seconds then shuts down
    by riki_22
    Hi everyone,

    I’m working on an ASUS B5402CEA notebook.

    B5402CEA_MB_R2.2
    HA4YT LA-L861P
    REV:1B

    The board powers on, fan spins for a few seconds, then it shuts down by itself.
    I suspect the BIOS might be corrupted.

    Could someone please check and clean (repair) the attached BIOS dump?
    I’ve also attached a few photos of the motherboard for reference.

    Thanks in advance for your help!

    Philips 47PFL4606 Powers on, works normal then powers off after a minute
    by simwalsh
    Hi,
    I am new to this forum and have searched for some answers with problems similar to mine.
    Philips TV powers on as normal for about a minute or less then click and no power at all not even standby light. If i disconnect from mains and reconnect it will power on again but for a shorter time. Once i leave it disconnected from main for a longer time it will power on for a longer period the next time.

    It sounds like a power supply issue?

    I have the board out and want to run some tests. Not sure what i should be doing but i put a 1k resistor across SB and +5v...
