I have been using my laptop for the past 2.5 years without any problem and one fine day it won't switch on. I have given my laptop to a acer authorised centre for servicing in Mumbai and it seems that it was due to a failure in power ic. But despite this it seems that they are unable to pinpoint the problem and informed me that it would take a while to diagnose the motherboard since there are multiple ic problems. They told me that they would try their best but it might be not be repairable. I would be grateful if anyone could give me their opinions about this issue.

    The power IC that the “Acer authorised centre for servicing” found out that is faulty, is a common fault with allot of laptops and not just an Acer laptop. Its probably a capacitor or a mosat that has shorted/burned out in the primary power stage of your laptop, and if you are lucky it might only be a capacitor and not a mosat that regulats the laptops cpu or gpu power to these components, and has also allowed a high current to burn either the cpu or gpu out, as then your cpu or gpu have burned out and you need to buy a new mobo as a cpu or gpu is not worth replacing and you will need to replace the whole mobo.

    The lowest spec Predator Helios 300 PH315-53 laptop mobo the i5-10300H HM470 N18PG62 4GB Acer part #: NB.Q7W11.001 is selling on eBay for $264.99. So if the cpu/gpu are affected then the easiest way to fix your laptop is to buy a used mobo on the web (as a new one from Acer is at least USD $1500) and do the work yourself, as changing a mobo is not a big job and you don't have to be a computer technician to do this job, as any computer savvy person could do this swap. Good luck and hope this helps you out.

    These are all the mobos fitted by Acer to your PH315-53

    I understand you say "I would be grateful if anyone could give me their opinions about this issue."

    Once your computer is repaired and in the future if you face any power or booting issues kindly follow the steps given below. The info provided below will be very helpfull for you.

    I am really sorry for the inconvenience..   Let us do the basic steps first..

    Doing the power drain and bios defaults will really help.  Kindly follow the steps given below:

    Turn off the laptop. Disconnect or unplug the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, you can find a  pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and – sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer.  Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.

    If you don’t find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery.  Turn off the laptop. Disconnect or unplug the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door.  Just below that you can find a latch.  If you move the latch you can remove the battery door. Once the battery is removed, flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 
     
    If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt) then please unplug all the cables and devices out of laptop.   Hold the power button for 1 minute.  After releasing the button you should wait a while before plugging in power. Just because the button has been pressed doesn’t bleed off all the residual electricity on the motherboard. Wait 15-30 minutes before plugging in power. Then once power is connected wait for a full battery indication before turning the system on. That allows the battery to fully reset it’s internal statistics.

    Connect all the cables back and restart the computer.  

    While turning on the computer, tap f2. It will go to bios. Press f9 once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear.  Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.   
     
    It might also be the issue with battery, charger or power outlet.   Try to use the charger in a different room on a different power outlet.  Try to bypass the surge protector and connect it directly to power outlet.    Try to use an alternative charger if possible.    Try to turn on the computer without the charger and check it  ( as long as the battery is not drained out )  

    Try windows x 
    go to device manager 
    expand Battery
    right click on all the items below battery – uninstall 
    Restart the computer 
     
    It should work fine..
