Hoping someone has some words of wisdom.

Powers on for 1 sec, keyboard lights up, blue light comes on, both fans work, then system stops and restarts in another few seconds. I tried to attach a video but it keeps timing out, can someone advise how to do this please and best format as I have an iphone to record. Photos attached for now.

Have done all the usual, power drain, remove RAM, battery, unplugged CMOS (though repair guy I consulted advised never to do that… but I see this mentioned in lots of places) etc etc but nothing changes. Repair guy had a cursory look, did same as I did, nothing more and tells me it is the MB though I not ready to give up on it just yet.

Anyone experienced the same thing or can offer some further information on what I could look for?

    Hi Nitro_515_56_58

    Your Nitro 515-56-58EE is likely stuck in a boot loop due to either a corrupted bootloader or a hardware fault. Since you’ve already tried power drain, RAM swap, and even CMOS resets, here are a few recovery steps to try before assuming motherboard failure:

    1. Interrupt boot 3x by holding down the power button for >5 seconds each time. This can trigger the Windows Recovery environment.
    2. If that doesn’t work, boot using a Windows Recovery USB drive and try Startup Repair or System Restore.
    3. If the system doesn’t recognize the drive or fails to post consistently, it might be a deeper motherboard, power delivery, or storage issue.

    If all recovery attempts fail, best to take it to Acer Service in your country for diagnostic. You’ve done the groundwork—now it’s time to rule out deeper faults.

    These Nitro gaming laptops are known for their power rails shortening out either at their DC_IN power port , check the main power rail and that mosfet shown in the caption below that needs replacing, if not, then chase the power rail and check all the mosfet and capacitors as that is where the problem is, as there is a circuit that is shorting out. Every board can be fixed if its not the cpu or dedicated gpu, but if the dedicated gpu burns out you can use the cpu graphics. Get another tech to look at your Nitro laptop as it can be fixed. Good luck.

    Check mosfet circled at DC_IN port area, if its shorted

    These are the Nitro AN515-56 boards if you need to replace your board

    Thank you so much for taking the time to respond, it is greatly appreciated. I will report back on how I go. Fingers crossed as I can't afford a new one or a MB, almost the same costs as a new laptop.

    Try all the above fixes to the main power rail, as I've got the exact same laptop model and I've been using the Nitro 5 AN515-56 since 2021 and its never given me any problems (just needed to do a Hard Reset) as this 11th Gen cpu with either the GTX1650 gpu or the RTX30xx gpu's are a very reliable and a solid performing gaming laptop. Good Luck.
