    Are you using the power adapter that came with your laptop and did you also checked the RAM modules seating/connections with the battery disconnected first? If you have a spare RAM module, try that. Also remove the CMOS battery (with the battery disconnected first) and shorten the +/- contacts inside the CMOS module with a bended paperclip this resets BIOS. Reinstall the coin battery with the + sign facing up and connect the battery. Plug in the barrel plug power adapter (not the USB-C charger) and try to boot.

    hi thanks . No I did not done anything on the ram yet for that I thinking I need to remove the main board as it is below the board other side of it . Coms I removed and put it back . But not sure about shorten or anything . I don’t know that . Also do you want me to get new cmos . Plus I use the main power cable adaptor of laptop not the c charger. My model is Helios 500 i7 ph17 .

    Did this problem occur for no apparent reason? Or did something happen before the problem arose, such as a change in thermal paste? Have you checked if the motherboard has all the primary voltages?

    What happens when you disconnect all peripherals like hard drive, ssd, wlan, daughter card, etc?

    Do a Hard Reset first as your laptops could have an EC chip that is frozen and stops your laptop from booting properly and a hard reset will unfreeze the chip and make your laptop boot properly, also check the ram modules if you have two modules installed, then boot the laptop with just one ram module and alternate and see if you have faulty ram as bad ram can cause a booting problem also, or even better, get new and similar ram from another laptop and test the laptop like that.

    If the hard reset doesn't fix this problem then you need to take your laptop to a technician in your area so that he can analyse the problem as an EC chip can be replaced or you could have other issues with the laptop like a faulty eDP cable or at worse a shorted dedicated NVidia GTX gpu that will need to be disabled so that you can only use the cpu graphics. Good luck and hope this helps you out.

    Hard Reset: Unscrew the sixteen (16) screws on the back cover of your PH517-51 laptop, then carefully pry up the base cover starting from the opening in SSD bay to take the cover off, take the main battery out and disconnect the RTC/BIOS battery and then short these batteries + & - pins at the mainboard plug and take the ram out, leave the laptop like that for at least 1 hour (preferably overnight) and then reconnect everything.

    Predator PH517-51 mobo, EC chip is at #16 that needs to be checked if its not shorted and needs replacing

    Do a hard reset and if that doesn’t work take your laptop to a technician as you can't do anything else as your laptop has either an eDP faulty cable, faulty EC chip, faulty gpu. A reset is all that you can do as you don't have the proper micro tools to be able to fix anything on a laptop.
