No Bootable Device (Predator Helios 300)

Mujae

I've had this laptop for about 4 years and have never encountered this problem before. The only thing that changes is I installed Windows 11 two days ago. Never dropped it, or spill anything on it. I just left my laptop alone for about ten minutes to get food, and when I came back the screen was off but I thought it was on sleep or something. But when I tried to turn it on there's a "No Bootable Device".

Tried to search for a solution on the internet and most of them suggests to change the boot mode to Legacy mode but I dont have that option, can't even disable the secure boot option. Other option is to check the hdd manually but I'm scared of screwing it up back there and ruin everything, so I'm looking for other option first.

I have no technical knowledge about computer, so easier languange is apreciated. Thanks in advance.

I suggest that you do a Hard Reset first and see if its not a frozen EC, bios or BQ chip, as a hard reset unfreezes and resets the laptop[ completely.

Hard Reset - open the back cover of the laptop, take the main battery out then press the power key for 10 seconds to release all the power out of the laptop, disconnect the bios battery and shorts its mobo plugs +&- pins to reset CMOS, then take all the ram out, leave the laptop like that between 30-60min to reset then connect all components back, as the laptop should reboot properly. After update the bios to version 1.15 as your PH315-54 is running on version 1.14.

If the hard reset doesn't fix the issue and due to this laptop being around 4 plus years old, it could be a main battery charge issue that stopped working and has turned your laptop off, as these batteries need replacing within 3-4 years.

Lastly, could be the Intel RST (Intel® Rapid Storage Technology) Driver version 18.6.1.1016.2 that was not installed properly or its corrupted when Win-11 was installed or the boot M.2 SSD drive of your PH315-54 model is faulty. Check all these things out and let us know how you make out, good luck.
