my acer nitro 5 laptop doesn’t power on when battery is connected and in charging both orange and blue light will start blinking and when it is powered on the keyboard lights just turn on and went off immediately and only orange light will start blinking, I tried replacing with another battery but it still doesn’t work what can I do?

If you are not concerned with the warranty you can open the back and try this: Disconnect the battery, locate the round CMOS module withe the 2 black and red twisted wires located under the battery and take the coin battery out, connect (shorten) the +/- contacts inside the CMOS module with a bended paperclip or short piece of electric wire for a few seconds inside the CMOS (the - contact is at the bottom and the + contact on the side) and put the coin battery back in the CMOS module with the + sign facing up, that will reset the CMOS/BIOS. Check if the RAM modules are firmly seated/secured or replace the RAM modules if you have spare SODIMMs and hold down the power button for 10 seconds to discharge any static buildup on the motherboard. Reconnect the battery, close the back of the laptop and plug in the adapter, the blue power LED and amber battery LED should turn on. Try to boot.

Check if there is an issue with the power adapter plug, if you post your full Nitro 5 laptop model, we can tell you what adapter is compatible assuming you are using the brick barrel power adapter and not a USB-C charger? When charging with the barrel DC plug fully inserted in the DC slot of your laptop till you hear a click, move/wiggle the plug a bit and observe the LEDs, if you see the LEDs changing color/blinking that would indicate a bad contact. Alternatively bring the laptop to Acer Services in your country for checking.
