Hello to everyone, I have bought an Acer Predator 17 g5 793 recently, the laptop came only with an SSD 250 GB and no other SSD or HDD. Today I bought a Seagate FireCuda 2tb 2.5 laptop small HDD and I plugged it in the big space after opening the lid with the cable plugged in nice and fine. Then after I closed the lid I turned it around and I pressed the power button, the button lights up for a second and then nothing happens, not the fans not the keyboard nothing works nothing happens, I go to press the button again, this time not even lighting up the button. I open the lid again I remove the Seagate and the cable for the Seagate then I run it again and it starts up fine. I went into BIOS menu and changed the boot options to my current SSD and to windows bootloader to second. I opened the lid again and placed the Seagate with the cable and again the same scenario with the power button lighting up for half a second. Then I went on to remove the Seagate and leave the cable inside closed the lid, pressed the power button and again the same scenario. I removed the cable and the predator ran perfectly. I guess there is a mechanism for keeping the lid closed because it doesn't allow me to power it on otherwise. But with the new HDD and the cable both I am not able to power the laptop on. I went to the people that gave me the HDD and the cable and I asked for help and after explaining the situation they get me another SSD to test if it was the HDD. It is not the new HDD, the test SSD was also plugged in the lid closed and everything but the laptop still didn't power on. I am lost, please help, I have searched the internet for at least a close situation as the one I am in but I have had no luck so far. I also posted on Acer Forums but no answer so far. I also updated the BIOS to the last version for my model laptop to 1.14.

Thank you in advance for any help.

Okay after a while I forgot to edit for anyone that had a similar problem with their Acer or actually almost any laptop for that matter. It seems that this is a cable issue. The cable given to me was for an Acer Aspire however it was not the correct one even if it does look the same. After the new cable arrived everything worked perfectly fine. I found another person with a similar problem a few days back before I received the cable that had the same problem as me only he had an HP laptop. In any case, I hope that this helps anyone in a similar situation.
