Hello,
I wanted to repaste my Acer Predator Helios 500 (PH-517-51-72EC) since it was getting really hot and now out of warranty. I had already sent it back to Acer before to get the fans replaced but it was still getting crazy hot for nothing, CPU throttling on the lightest games, etc ... I guess they didn't put thermal paste again at the time.
So I opened the laptop, removed all the screws, the pins connected, etc ...
I then removed all the thermal paste from the GPU, CPUs and all the things around that had some prior, using paper towels and alcohol (33% isopropyl and 66% ethyl alcohol)
I repasted with Thermal Grizzly thermal paste, just a little bit on everything.
Finally i closed it with a few screws making sure to connect every pins back again to try it but it doesn't power on at all, nothing happens at all when I click the power button.
I don't understand where it could come from since if I damaged something it could at least boot to bios for more info but it seems like it doesn't power on at all.
Thanks in advance for those that can help me, I'm a student so I really need my laptop for school and everything ...

  • Did you use ethyl alcohol to clean the motherboard components? In my opinion, you should have used 99% isopropyl alcohol, which contains as little water as possible in the composition. Did you disconnect the battery before performing the procedure and check that the heatsink is not misaligned?

    I did use this alcohol it was the only one I could find but from what i searched before it was supposed to be fine.
    I also did disconnect the battery every time and i made sure everything was placed correctly a second time.

    Hi M003T,

    Are you getting any light indication when you press the power button?
