E5-571G-78GQ My laptop won't open anymore, it still lights but not for long except the orange one

Hello experts or technicians I really need your help immediately. My laptop won't open anymore, it still lights but not for long except the orange one cuz I was charging it. When I click the power button it lights blue as usual but then stopped for a couple of seconds. I'm no expert but I tried several tutorials/methods to solve this even trying to remove the ram and placing it back or the unplug battery and charger while holding the power button 30secs/1min/2min method don't work anymore cuz last time I did, it worked but now it's different. I was also trying to do the bios reset of removing the battery but I don't think my laptop has it since I checked, I bought a new battery for it since it's the reason why it stopped working due to unchargeable battery. I've been using this laptop for years doing schoolworks and playing games for boredom, and I still be needing it for college. I can't afford a new one or even let it fix by a technician, my dad would probably be mad of my stupidity😭 so any help would be really much appreciated🙏🏼

This is my model:

Acer E5-571/E-531 series
